About this Guide The Trending Historical Data manual is intended for process control engineers and operators who are responsible for analyzing real-time and historical data using iFIX®. The manual assumes knowledge of the Microsoft Windows environment, and basic iFIX operations and concepts.

Reference Documents

For related information on iFIX, refer to the following manuals:

• Building a SCADA System

• Understanding iFIX

• Setting Up the Environment

• Creating Pictures

Introduction Historical Trending provides an automatic, comprehensive, and long-term means of sampling, storing, and displaying process data. Once data is collected from SCADA servers (or SCADA nodes), you can examine the data in an object-oriented chart in the Proficy iFIX WorkSpace.

With Historical Trending set up to collect process data, you have a powerful tool to help you:

• Analyze process trends.

• Archive process variables to meet federal regulations.

• Monitor the efficiency of products.

• Maintain equipment.

• Analyze post-process data.

iFIX® lets you configure both historical and real-time pens in the same chart, and gives you the ability to assign multiple time ranges for each pen. There is no limit to the number of pens you can add to your charts.

Other features of charts include:

• Complete iFIX object color and style properties for each pen.

• Multiple X and Y axis configuration.

• Zoom capability in the run-time environment.

• Left-to-right and right-to-left scrolling of real-time data.

• Tool tips time cursor that shows the time and date of a point in a trend.

• The use of an expression as a data source for real-time pens.

• Configuration and property adjustment in the run-time environment.

The features cited in the above list are covered fully in the Using Charts to Analyze Process Trends chapter.

How Historical Trending Works

Historical Trending consists of the following elements:

Historical Assign – defines your collection strategy. Here you define:

• The tagnames (or data sources) from which you want to collect data. The tagnames are organized into collection groups.

• Collection parameters for each collection group (node, rate, phase, qualifier, status, and tags).

• Length of the historical files in hours and how long the files are stored on the collection server's hard disk.

Historical Collect – collects data on all tagnames assigned to each active collection group.

Chart – displays historical and real-time data as an iFIX object in the Proficy iFIX WorkSpace.

Historical Assign gathers process data from local and remote SCADA servers, configures the data for collection at a specified rate, and stores the data in collection groups. Historical Collect then collects the data and stores it in historical data files on SCADA servers running iFIX. The data is then retrieved and displayed in a chart in the Proficy iFIX WorkSpace.

Example of Historical Trending in Use

The following is an example of how Historical Trending can be applied to collected data on a local server and provide a process record:

• Sample Application

• Interpreting Historical Data in the Sample

Sample Application

If you want to monitor the temperature of a heated tank, the most crucial points of the application are the I/O points that:

• Receive data from the sensor measuring the tank's current temperature.

• Monitor the setpoint value.

Refer to the following figure.

Collecting Process Data

An Analog Input block, AI_TEMP, on the SCADA server monitoring a tank's temperature, receives input from a sensor in the tank. AI_TEMP's current value is an important point to trend because it provides a historical record of the tank's temperature.

An Analog Output block, AO_CNTL, sends setpoint values to the PLC that controls the tank's heater. AO_CNTL's current value is an important I/O point to trend because Historical Trending can record how closely the actual tank temperatures compare to the setpoint values that are sent to the PLC.

In a normal operation, the trend display for both AI_TEMP and AO_CNTL should be similar because the input values for AI_TEMP will match the output values for AO_CNTL (thereby maintaining an even temperature).

The following figure shows how data collected on these two blocks appears during normal operation.

Example of a Normal Process

If the heater in the tank failed, the setpoint value (sent to the PLC) from AO_CNTL would not change the tank temperature to the desired temperature. The following figure shows how data collected by Historical Trending may appear in this situation.

Example of an Abnormal Process

Interpreting Historical Data in the Sample

The display shown in the Sample Application section presents a situation where the input value trended from AI_TEMP fell while AO_CNTL's setpoint value remained constant. While looking at this data in a chart, you can determine if:

• There is a break in the communication between the PC to the PLC.

• The heater in the tank is defective and cannot maintain the temperature.

• An external factor is affecting the heater and needs to be examined.

The important points illustrated in this example are that Historical Trending:

• Provides a permanent record of your process that you can use to track process inconsistencies.

• Allows you to compare process inconsistencies to product quality produced during the events.

• Allows you to display collected data from other processes with data collected from a similar process.

Getting Started This chapter details how to begin trending real-time and historical data. It also introduces the concepts of historical data files and their storage. The sections in this chapter include:

• Before You Begin

• Historical Data File Storage

• Starting and Stopping Data Collection

• Enabling Historical Trending Security

• Overview Checklist

Before You Begin

Before you start to assign and collect data, you should consider the following:

• Have you installed iFIX and configured it correctly?

• Have you verified that your historical data paths in the SCU are correct?

• Have you configured your database so you can access data?

• Are you familiar with the Proficy iFIX WorkSpace and the nature of object-oriented graphics?

For more information on configuring and managing iFIX, refer to the Setting up the Environment and Understanding iFIX manuals. For more information on database configuration, refer to the Building a SCADA System manual.

Historical Data File Storage

Data collected by Historical Collect is stored in the historical data path defined in the SCU. Each node that data is collected from has its own subdirectory beneath the historical data path.

Refer to the following sections for more information about historical data file storage:

• Historical Assign File Location

• Historical Collect File Location

• Using File Servers

Historical Assign File Location

Historical Assign creates a file for each collection group in the historical data path. The following is an example of the format using the default system path:

C:\Program Files\Proficy\Proficy iFIX\HTR\HTRGRP01.DAT

Historical Collect File Location

Historical Collect files reside in the Historical data path. The following is an example of the format using the default system path:

C:\Program Files\Proficy\Proficy iFIX\HTRDATA\nodename\YYMMDDHH.H04

where YY is the year, MM is the month, DD is the day, and HH is the hour (a four-hour file is shown in this example).

Historical Collect can be configured to start automatically and run on any node. Refer to the Setting up the Environment manual for more information on running Historical Collect automatically.

Using File Servers

An optional way to store Historical Collect files is to save them on a file server. Using a file server to store historical data files requires a few adjustments to your configuration:

• Because each node running Historical Collect has a subdirectory named after it (in which it stores its own historical collect data files), unique node names must be assigned to all nodes running Historical Collect. Using different node names will prevent a node running Historical Collect from overwriting another node's historical data files.

• A node must specify the path of the file server it needs to access in order to display historical data in a chart. This historical data path is configured in the SCU. Refer to the Configuring iFIX Using the SCU chapter in the Setting up the Environment manual to set up directory paths in the SCU.

File Servers

In the previous example, the paths to the file server (F:) are set to separate directory paths.

Avoid specifying THISNODE as the data source node name in Historical Assignment when you collect historical data on a file server. While iFIX can collect historical data from the local node when THISNODE is used, the chart used to display the data cannot determine on which node the data resides.

You can access your historical data files while Historical Collect is writing to them. For example, a chart in a picture can access recently-collected data depending on how you configure the chart properties. Likewise, the iFIX Backup and Restore Wizard can back up your historical data files while the Historical Collect is writing data to the file.

NOTE: We do not recommend backing up historical data files while data is being collected because you may lose data or back up an old obsolete file. Instead, shut down iFIX prior to backing up your historical data files.

Starting and Stopping Data Collection

Before you can start collecting data, you must assign specific database tags to trend using Historical Assign. Refer to the Implementing Historical Trending chapter for more information on how to do this.

The follow sections show you the basics of starting and stopping Historical Assign and Historical Collect:

• Starting Historical Assign

• Exiting Historical Assign

• Starting Historical Collect

• Stopping Collection

Starting Historical Assign

You can start Historical Assign by clicking the HTA button on the Application toolbar (Classic view), or from the Proficy iFIX WorkSpace system tree, by opening the Historical Configuration folder and selecting Historical Assignment. In the following example, the Historical Assign window has

been configured to include node COLLECT2, which has a collection rate of 30 seconds, a phase of 0 seconds, and an active status. All of the Historical Assign parameters are described later in this chapter.

Historical Assign Window

Exiting Historical Assign

When you want to exit Historical Assign, select Exit from the File menu.

After you create a historical collection group with Historical Assign, you can start collecting data. When you start Historical Collect, it retrieves data from the tags assigned in Historical Assign.

NOTE: If you add or delete a tag from a database that is currently being collected, Historical Collect resolves all the links to that database. This can cause a gap in collected data for all tags being trended in that database.

Starting Historical Collect

To start Historical Collect, select Mission Control from the Proficy iFIX WorkSpace and click the HTC tab. Click Start to begin collecting data. The Historical Collect tabbed page displays the number of overruns since collection started. Overruns are described later in this section.

You can also start Historical Collect automatically using the Task Configuration of the SCU. For more information on configuring tasks, refer to the Configuring Startup Tasks section of the Setting up the Environment manual.

If you want the Historical Collect application that you added to the task list to start as a service under Windows, you must enable iFIX to run as a service. After you do this, if you log out of Windows, Historical Collect will continue to collect data. For more information on configuring iFIX to run as a service under Windows, refer to the Running iFIX as a Service section of the Setting up the Environment manual.

Overruns

When Historical Collect cannot collect all of the data at the rate specified, a historical collect overrun can occur. When an overrun occurs, values for some tagnames in the group are not collected at the configured rate. Temporary conditions such as heavy network traffic, network upsets or off-line nodes can cause overruns.

However, a repeated number of overruns may indicate that the phase value for the group needs adjustment. You can prevent overruns by phasing the data collection rate. Refer to the Defining a Collection Group section for information on phasing to prevent overruns.

Stopping Collection

To stop collection for all groups, click Stop on the HTC tabbed page in Mission Control.

NOTE: If you make any changes to a collection group in Historical Assign after you start Historical Collect, you must stop and restart Historical Collect so that the system can read the new configuration.

System Shutdown

If you shut down iFIX, data is not collected or written to historical data files. Historical data files will contain data before the shutdown, and collection will resume when you restart Historical Collect. You can also continue to collect historical data after shutdown by running Historical Collect as a background task. Refer to the Starting Historical Collect section for more service task information.

Overview Checklist

The following list outlines the process for setting up and running Historical Trending.

To set up and run Historical Trending:

1. Configure the SCU and your database and historical paths.

2. Assign database blocks for trending and specify the parameters for collection.

3. Start historical collection.

4. Add a chart to the Proficy iFIX WorkSpace, and configure the chart to display the data you collected.

5. Run the chart in the Proficy iFIX WorkSpace to view the collected data.

Implementing Historical Trending This chapter helps you implement a strategy to effectively trend historical data using Historical Assign and Historical Collect. It includes the following sections:

• Assigning Blocks for Trending

• Creating a Collection Group

• Defining a Collection Group

• Suspending a Collection Group

• Modifying a Collection Group

• Deleting a Collection Group

Assigning Blocks for Trending

The first step in implementing Historical Trending is selecting database blocks (or tags) with Historical Assign. In Historical Assign you create a group of tagnames called a collection group. This group identifies specific database blocks that contain process data that you want to trend. The following sections show you how to:

• Select database blocks for a collection group.

• Use Historical Assign to set up the group to collect process data and store it in historical data files.

Determine Which Blocks To Trend

To effectively configure Historical Assign, you must develop a group that collects meaningful process data. If you assign blocks in Historical Assign that monitor critical process points, you can later create charts that let you view useful trends of your process, either from one or multiple process areas.

You can also plot pens from different groups in the same chart. Therefore, review the database that monitors your process to determine which blocks you need to trend.

Application Example

In the application example in the Introduction, both AI_TEMP and AO_CNTL are associated. They contain, respectively, real-time data on the actual temperature of the tank and the setpoint values that the SCADA node sent to the PLC to control the tank's temperature. In this example, trending data from each block provided a meaningful process record when examining the history of a process. The following figure illustrates this example.

Trending Data From One Process

In another application, suppose you have three tanks for which you want to collect process data. You can collect data on all the Analog Input blocks that receive temperature input and the Analog Output blocks that return setpoint values to the PLC to control the tanks' temperatures. The following figure illustrates this setup.

Trending Data From Multiple Processes

Once historical data is collected on a number of important database blocks, you can create charts that allow you to analyze your process from a number of perspectives.

For example, using the information in the preceding figure, you can display historical data on how:

• Real-time input values from each tank compared to each tank's output value.

• Inputs varied from tank to tank.

• Outputs from the SCADA servers varied from tank to tank.

For detailed information on how to use charts, refer to the Using Charts to Analyze Process Trends chapter.

Whatever you require from trending historical or real-time data, Historical Trending allows you to assign, collect, display, and compare specific process trends to improve your process. It also gives you control at all levels, from changing the collection length in Historical Assign to changing chart properties at run-time.

Creating a Collection Group

The following is a summary of the tasks required to create a collection group.

To create a collection group:

1. In Historical Assign, on the Group menu, click Add, or double-click the next available group number or row. The Group Configuration dialog box appears.

2. Select the node containing the blocks from which you want data collected.

3. Specify an optional qualifier block that determines when the data collection state for the group is on or off.

4. Select a data collection rate for how often you want data collected.

5. Select a phase value to disperse the data collection load over time and prevent overruns.

6. Select the tagnames for data collection.

7. Enter a deadband limit to filter out process fluctuations.

8. Save the collection group.

Defining a Collection Group

You can create a new historical collection group by selecting Add from the Group menu. You can also modify an existing group by double-clicking that group from the Historical Assign window.

The following sections detail the tasks involved in establishing a collection group file:

• Setting Historical Collect File Length

• Purging Historical Files

• Selecting a Node

• Selecting Tagnames for Trending

• Entering a Qualifier Block for On/Off Collection State

• Entering a Data Collection Rate

• Phasing Data Collection

• Entering a Deadband Limit for Data Collection

Setting Historical Collect File Length

You can specify the length of each historical data collection file for all collection groups.

The collection length button choices are based on a 24-hour clock:

For the collection length...

New files start at...

4 Hour 0:00, 4:00, 8:00, 12:00, 16:00, and 20:00

8 Hour 0:00, 8:00, and 16:00

24 Hour 0:00 (midnight)

NOTE: For very active process loops where values are rapidly changing, we recommend

shorter collection file lengths of 4 or 8 hours. Conversely, for process loops where values are not fluctuating as often, set a 24-hour file length.

When you change the collection length, you must save the Historical Assign file for the changes to take effect. Also, if you change the collection length while Historical Collect is running, you must stop and restart Historical Collect so that the system can read the new setting and create files accordingly.

NOTE: When you start Historical Collect, the first data file only records data from the start time until the end of the next data collection interval. For example, if you start historical collection at 12:25PM, and enter a collection rate of 4 hours, a file is created for the 12:00 to 4:00 period, but the file only contains data starting at 12:25PM.

Purging Historical Files

Often times you may have historical files on your local machine that you don't use any more, or that are taking up extra disk space on your collection node. For this reason, you may want to prevent unwanted files from storing on

your machine by automatically purging them. Historical Assign lets you do this with ease.

To purge old historical data files for all collection groups, select the Automatically Purge Data Files After Days check box. In the Days field, enter the number of days you want data to be saved before it is automatically purged. The valid entries for saving data are from 2 to 200 days. File purging occurs at midnight, 00:00 hours, or when Historical Collect starts for the first time in a day.

If you deselect the Automatically Purge Data Files After Days check box, old data files are not purged and remain on your collection node. When you change the purge setting, you must save the new setting for the change to take effect. You must also stop and restart Historical Collect.

NOTE: Before historical data files are purged, you can remove the files from the collection node's hard disk and copy them to a back-up disk for future use.

Selecting a Node

In order to begin collecting data, you must enter the SCADA node that contains the tagnames for the collection group.

Using a Local Node Alias

The local node alias feature in Historical Trending allows you to enter the THISNODE placeholder for the node portion of a tag, thereby permitting you to share historical collection groups among nodes.

To use this feature, select THISNODE from the list in the Node Select dialog box. When you select this option, historical data is stored in a HTRDATA path in the local node's directory.

For examples of how local node alias works and a complete description of the feature, refer to the Local Node Alias section of the Mastering iFIX manual.

Selecting Tagnames for Trending

You must also enter the tagnames that you want to trend from the selected node.

NOTE: Only floating point fields (F_) can be trended.

Entering a Qualifier Block for On/Off Collection State

You can specify an optional qualifier block to collect data for a specific interval when process data has changed. For example, if your plant is temporarily down for maintenance, you can specify that data not be collected for that period. In the Qualifier field, enter the tagname of the block that determines when the data collection state for the group is on or off.

The Qualifier block is usually a Digital Input or Digital Output block. You cannot use a Digital Register block as a qualifier block. When the digital block changes from Open to Close, data collection starts for the group. When the digital block changes from Close to Open, data collection stops.

If the qualifier block is a block other than a digital block, then a value of 0 stops collection. Any value other than 0 starts collection.

If a non-digital block is assigned as a qualifier, the following message appears:

The qualifier is not a digital point. Use anyway?

You must then choose either to create the block anyway, or cancel out of the message dialog box.

If a non-existent block is assigned as a qualifier, the following message appears:

This qualifier not found in database. Use anyway?

You must then choose either to create the block anyway, or cancel out of the message dialog box.

When you start Historical Collect, an operator message is generated warning that the qualifier is not found.

Entering a Data Collection Rate

Using the Rate field, you can define how often values are to be collected for the tagnames in the collection group.

The following table lists valid collection rates.

Valid Collection Rates

Rate Time

1s 1 Second

2s 2 Seconds

10s 10 Seconds

20s 20 Seconds

30s 30 Seconds

1m 1 Minute

2m 2 Minutes

10m 10 Minutes

20m 20 Minutes

30m 30 Minutes

The Rate field has a default value of 30 seconds.

IMPORTANT: We recommend a minimum collection rate of ten seconds for remote nodes.

NOTE: The collection rate operates off the system's clock time rather than when Historical Collect is started. That is, time increments (hours, minutes, and seconds) for clock time are maintained from midnight (00:00:00) to the present. So no matter when you start Historical Collect, the rate function runs off the system's clock and begins its collection process in relation to the clock's setting.

Phasing Data Collection

Phasing offsets the collection process for a group by a specified amount of time. When collection starts, it waits for the phase period to elapse once. Thereafter, data is collected according to the rate defined for the group.

Preventing Overruns

The main benefit of phasing collection rates when you collect data is to prevent overruns. An overrun occurs when Historical Collect cannot collect all the data at the rate specified.

Phasing Examples

If you assign a phase time of 2 seconds and a rate time of 10 seconds, then once collection starts data will be collected at 2 seconds, 12 seconds, 22 seconds, 32 seconds and every 10 seconds thereafter.

System Clock Showing Phasing

Here is another example of phasing used when collecting data from two nodes and four collection groups:

A node is collecting data from a group of 80 tagnames on node A and a group of 80 tagnames on node B. You can phase the collection to collect data on 60 tagnames from node A, and then 60 tagnames from node B. You can then phase the collection to collect data on another 20 tagnames from node A and node B. This phase configuration would be entered as follows:

Node Tags Time

Node A tags 1 - 60 phase 2 seconds

Node B tags 1 - 60 phase 4 seconds

Node A tags 61 - 80 phase 6 seconds

Node B tags 61 - 80 phase 8 seconds

In this example, the task of collecting data for all tagnames is distributed over a period of 8 seconds.

In iFIX, the phase value choices are in two-second increments from 0 to 58 seconds. The default value is 0 seconds. The phase value you enter must always be smaller than that entered in the Rate field.

Historical Trending uses less CPU time to process one group containing 80 tagnames than it does to process eight different groups with ten tagnames per group. Therefore, phasing can be an effective strategy to save disk space and make data collection more efficient.

Enabling Phasing During the First Minute of Data Collection

To enable phasing during the first minute of data collection, you must create a new registry subkey.

To create a new registry subkey:

1. Click the Start button, and then click Run. The Run dialog box appears.

2. In the Open field, type regedit.

3. Click OK. The Registry Editor appears.

4. Open the following key folder:

HKEY_CLASSES_ROOT\FIX32\BrowseTree\Local Node\Historical Assignment

5. Create a new DWORD Value called initphase.

6. Double-click initphase.

7. In the Value data field, type 1.

8. Click OK.

Entering a Deadband Limit for Data Collection

Using a deadband limit is a convenient and powerful way to compress data. During times when process values change by insignificant amounts, the deadband limit can improve system performance and decrease the amount of disk space used by historical data files. It does so by controlling how much the current value can deviate from the last recorded value before Historical Collect records the new value in the historical data file.

For example, if a limit value for a specific tagname is 1.000, then a value change of 1.000 or greater is required before Historical Collect saves the new value. Any new values less than 1.000 are not saved.

To limit the amount of data recorded by Historical Collect, enter a deadband limit in the Limit field. The default value is 0.5.

NOTE: If the limit value is 0, the system saves every sample. Because of this, tagnames with a limit value of 0 use the maximum amount of disk space.

The following figure illustrates how setting the Limit field reduces the amount of data collected by Historical Collect. In this example the Limit field is set to 2.5. Of the 16 data points shown, only three are recorded by Historical Collect. Data points within the shaded areas are not recorded because they fall within the 2.5 deadband limit.

Deadband Limit Example

Let's take another look at the figure. The first recorded value shown is 50. Therefore, the next value that Historical Collect records must be greater than or equal to 52.5, or less than or equal to 47.5.

The second value recorded is 54. The deadband limit now applies to the current value of 54. Therefore, the third value that Historical Collect records must be greater than or equal to 56.5, or less than or equal to 51.5.

Finally, the third value recorded is 51. The deadband limit now applies to the current recorded value of 51.

Estimating Required Disk Space

To obtain an estimate of how much disk space you will need to store historical data for a specific number of collection groups, use the following formula:

File size in bytes = (3500 x A) + ((8 x B) x C)

A – the number of groups collected for the file.

B – the average number of tagnames per collection group.

C – the number of values written to the file for all collection groups.

For example, Historical Assign is configured to collect data on 2 groups at a rate of one minute, in 4-hour files. One group consists of 80 tagnames and the other 20. In this case, the values for A, B, and C are as follows:

Variable Value Calculation

A 2 2 groups collected per file.

B 50 Average = (80+20)/2=50

C 480 60 values/hour x 4 hours x 2 groups = 480

Insert these values into the file size formula to compute an estimate of how much disk space is required to store the historical data:

(3500 x 2) + ((8 x 50) x 480) = 199,000 bytes

Therefore, this configuration uses approximately 200K for every 4-hour file.

NOTE: This formula assumes that the values exceed the tolerance at each scan period, and therefore provides only rough estimates. Depending on your database configuration, the results may differ.

Suspending a Collection Group

In Historical Assign, you can suspend a collection group temporarily. For example, if current data is unimportant to you, or the data is taking up too much disk space on your system, you may want to make that data inactive. To suspend a collection group, select Deactivate from the Group menu and restart Historical Collect.

To reactivate a group, select the group and then select Activate from the Group menu. Again, restart Historical Collect.

Modifying a Collection Group

If you want to change the collection parameters for a group at a later date, select the group in Historical Assign and double-click it or select Modify from the Group menu. Make changes to the group in the Group Configuration dialog box.

NOTE: If you make changes to a collection group in Historical Assign (such as adding new tags to a group) after you have started Historical Collect, you must stop and restart Historical Collect so that the system can read the new configuration.

Deleting a Collection Group

If you want to delete a group, select the group in Historical Assign and then select Delete from the Group menu. The following message appears:

"Are you sure you want to delete this group?"

Click Yes to delete the collection group, or No to cancel the deletion.

Using Charts to Analyze Process Trends Given the vast amount of data you can collect with iFIX, you need a way to present the information and react to the results. Once you have collected the necessary data, you can display the data as process trends in a chart. iFIX charts let you plot both real-time and historical data on the same chart, and gives you easier access to the information you need.

Refer to the following sections for more information on charts:

• What is a Chart?

• Comparing Standard Charts and Enhanced Charts

• Plotting Different Types of Data

• Working with Standard Charts

• Working with Enhanced Charts

• Displaying SQL Data

What is a Chart?

Charts are an effective way to display trend data to users. They enable you to view specific sets of data relative to other data, thereby allowing you to continually determine the status of your process.

Charts are objects, and as such contain properties, methods, and events, just like any other iFIX object that you can add to your picture. This means you can animate a chart through VBA, or change the chart's colors or other properties. The behavior of iFIX objects is fully documented in the Creating Pictures manual. The VBA properties, methods, and events are documented in the iFIX Automation Reference manual.

iFIX offers many types of charts for displaying your trend data. They are divided into two groups: Enhanced Charts and Standard Charts. Enhanced Charts include many types of statistical process charts and are highly customizable. Standard Charts allow you to configure an unlimited number of data sources, in any combination, for your chart.

For more information about each type of chart, refer to the Types of Charts section.

Types of Charts

iFIX provides two types of charts for displaying trend data. The two types of charts are Enhanced Charts and Standard Charts.

Enhanced Charts

Beginning with iFIX 5.0, Enhanced Charts are available in addition to the Standard Charts always available with iFIX. Enhanced Charts include the following types of charts:

• Line/MultiLine Chart: displays the trend of a variable(s) over time. In this chart, the X-Axis always represents the time. Both real time and historical data will be allowed to co-exist within the same Enhanced Chart. You can plot an unlimited number of data sources, in any combination or type. Any database block is allowed.

• SPC - X-Bar Chart: displays the real-time average value (X-Bar) from a Statistical Data (SD) database block.

• SPC - R-Bar Chart: displays the real-time average range (R-Bar) from a Statistical Data (SD) database block.

• SPC - S-Bar Chart: displays the real-time average standard deviation (S-Bar) from a Statistical Data (SD) database block.

• Histogram Chart: displays a frequency distribution. The data for the Histogram Chart comes from the Histogram (HS) database block.

• XY Chart: displays the relationship between two DataSets. The data can either be real-time or historical in nature. However, only type of data can exist in the same Enhanced Chart. Any database block, except SD, HS, ETR, SQT, SQD, or PA is allowed.

Enhanced Charts are highly customizable; you can customize every aspect of a chart's appearance, from the color theme to the font used for the title. For more information on customizing Enhanced Charts, refer to Working with Enhanced Charts.

Additionally, unlike with Standard Charts, with Enhanced Charts, you can export the data being viewed in the chart. You can export in a variety of graphical and text/data formats to the Windows clipboard, a printer, or a file.

Standard Charts

iFIX Standard Charts are multi-pen, meaning that they allow you to configure multiple pens in one chart. Multi-pen charts can plot an unlimited number of data sources, in any combination. There is no limit to the number of pens you can add to your picture, you are only limited by the memory in your system. You can set up each trend line with a different color and marker style, and different time ranges. For more information on customizing Standard Charts, refer to Working with Standard Charts.

Adding Charts to Your Pictures

To add a chart to your picture, click the Chart button on the Shapes toolbar (Classic view) or on the Insert tab, in the Charts group, click the desired chart style (Ribbon view - pictured in the following figure). If the Toolbox is enabled, click the button on the Toolbox.

Chart Selection Options - Ribbon View

After selecting the desired chart, the cursor becomes a plus sign. Click and drag the mouse in an area of the picture where you want to place the chart. When you initially add a chart to your picture, it is created with a default name of Chart#, and the chart appears in the system tree in the Proficy iFIX WorkSpace.

Plotting Different Types of Data

iFIX charts plot three types of data:

• Real-time – Data that is current.

• Historical – Data obtained at a previous time by Historical Collect.

• T_Data – Data obtained from a trend block of a real-time data source.

The type of data plotted is determined by the data source you have selected. For Standard Charts, this is referred to as the pen type. For Enhanced Charts, it is referred to as Data Sources. The pen type, or data source, determines which properties are available in your chart.

The following table lists some of the common pen, or data source properties and their availability for each type.

Properties Based on Type

Property Historical Real-time (including T_Data)

Fixed Date Enabled Disabled

Fixed Time Enabled Disabled

Days Before Now

Enabled Disabled

Duration Before Now

Enabled Disabled

Interval Enabled Disabled

NOTE: If you are using a historical data source, the Tolerance, Deadband, and Refresh Rate fields have no effect on data retrieval.

This section primarily focuses on how to set properties for historical data you want to plot in a chart. For additional information on working with properties for real-time data, refer to the Adding a Chart section in the Creating Pictures manual.

Working with Standard Charts

The following sections describe how to modify many of the properties of a Standard Chart:

• Working with Standard Chart Properties

• Defining General Standard Chart Properties

• Changing the Appearance of a Standard Chart

• Animating Standard Chart Properties

• Working in the Run-time Environment

Working with Standard Chart Properties

The Chart Configuration dialog box allows you to select and modify various properties for your charts. This dialog box contains two tabs: General and Chart. Properties selected from the General tabbed page apply to the entire chart. For example, you can enable run-time interaction in the entire chart (for zooming and pen selection, for example) by selecting the Highlightable and Selectable options.

Properties accessed from the Chart tabbed page, on the other hand, are applied per pen, unless you select the Apply to All Pens check box. The following section describes the methods of applying properties to your chart.

Applying Standard Chart Properties

There are several ways you can apply selected properties to your charts using the Chart Configuration dialog box:

• Select a new pen in the Pen List.

• Click OK.

• Click Apply.

• Select the Apply to All Pens check box.

Each of these methods are described in the following table.

Methods of Applying Properties

Use this method...

To...

Select a new pen in the Pen List

Automatically apply properties based on the selected data source. This method takes precedence over other methods of applying properties: you do not have to click OK or Apply to apply the pen property, and, if you click Cancel after you have selected a pen, the properties are still applied.

Click OK Quickly apply selected properties to your chart and close the Chart Configuration dialog box.

No matter which method you use to apply properties, you must click OK to close the dialog box.

Click Apply View a property change immediately without closing the Chart Configuration dialog box. For example, if you want to change the foreground color of a chart from gray to white, change the color and click Apply. The color of the chart will change while the Chart Configuration dialog box stays on your screen.

You are not required to click Apply to apply properties to your chart.

Select the Apply to All Pens check box

Apply properties to all pens added to a chart. Refer to the Applying Properties to all Pens section below for more information.

Applying Properties to all Pens

iFIX allows you to easily define time, X and Y axis, grid, and legend properties for every pen you add to your chart. You can do this by simply selecting the Apply to All Pens check box on the Chart tabbed page. For example, you may want all of the pens in your chart to have the same legend. To accomplish this, click the Legend tab and select the properties you want. Next, select the Apply to All Pens check box. Exit the dialog box by clicking OK.

Defining the Pen Type

One of the most dynamic features of charts is the integration of both real-time and historical data in the same chart, which lets you easily view all types of data in the Proficy iFIX WorkSpace. You need to define a pen for each data source you want to trend. Before you can add a pen to your chart, however, you must specify a data source for that pen. The following sections show you how to select a data source and configure additional pen properties.

Adding Pens to Your Chart

Each pen that you enter must be defined by a data source. At the top of the Chart tabbed page of the Chart Configuration dialog box is the Data Source area, which lists the pen names in Data Server.NODE.TAG.FIELD format. By default, a sample pen is displayed in the pen list with the correct syntax you must use to address a data source.

There are two ways you can add a new pen to your chart:

1. Modify the existing sample pen by double-clicking it and entering the data source in the syntax illustrated in the sample.

2. Delete the existing sample pen by double-clicking it, highlighting it and pressing <Delete>, and do one of the following:

• Click the Add Pen button in the Pen List area, and enter a data source in the field that appears.

• Double-click a blank field in the Pen list and enter a data source in the field.

You can also click the Browse button to the right of the field to display the Expression Builder, which allows you to search for global data sources through a data source browser. To learn how to use the Expression Builder and define data sources, refer to the Animating Object Properties chapter in the Creating Pictures manual. For more information on data sources, refer to the System Architecture section of the Understanding iFIX manual.

iFIX also gives you the ability to add pens to your chart in the run-time environment by writing a VBA script. Refer to the Writing Scripts manual for more information.

NOTE: Whatever method you use to add pens to your charts, do not add more than 25 pens. Doing so may cause your chart to disappear.

To modify an existing pen in the pen list, double-click the pen and enter an alternate data source. To change the order of the pens in the chart's legend, click the pen you want to move in the Pen List area, and then click either the up or down arrow.

To delete a pen, double-click the pen from the list and click the Delete button.

Defining Data Properties

To control how the data is presented by the configured pen(s), you can define data properties for each pen in your chart. You can do this by simply selecting the properties you want on the Chart tabbed page. The following properties can be defined:

• High Limit – Displays the high limit value defined for the selected data source.

• Low Limit – Displays the low limit value defined for the selected data source.

• Fetch Limits – At run-time, automatically retrieves the low and high limits assigned to the selected data source.

• Maximum Display Points – Determines how many data points will be displayed in the chart over a given span duration.

• Show Line – Displays the trend line for the selected data source.

• Constant Line – Displays a constant horizontal line at the current value of the pen.

• Show Gaps – Determines whether a blank space or a line is displayed to represent an area in a plot where there is no data.

The following table illustrates some examples of data properties applied to a chart.

Data Property Examples

Use this property...

To...

High Limit

Low Limit

Specify high and low limit values for trending. To do this, enter the low and high limit values you want to trend for the selected data source in the Low Limit and High Limit fields, respectively.

Fetch Limits Retrieve the limit range assigned to the data source at run-time. For example, you may have a data source with limits that are unknown or prone to change in the configuration environment.

By selecting Fetch Limits, you can set the pen's high and low limits equal to that of the data source at run-time.



To...

Maximum Display Points

Determine how many data points displayed in the chart based on a set duration.

For example, if the maximum points are 500, and the duration is 500 seconds, then the maximum number of points that the chart will maintain is 1 per second.

Selecting a Historical Display Mode

Pens displaying historical data offer additional flexibility in how the data is displayed by offering a historical mode, available on the Pen tab of the Chart Configuration dialog box. Select a mode from the Historical Mode drop-down list. The display mode determines how iFIX selects data from a historical data source and displays it in the chart, and determines what each displayed value represents.

Historical modes are directly related to Span Interval and Span Duration properties for the time group. The Span Interval determines the range of data that the display mode uses to calculate the point of data that is trended. Time group properties are further described in the Defining Time Ranges section.

The following table shows the different historical modes you can choose from, and how trending differs for each mode.

Historical Modes

If you select this mode...

Then...

Sample The last valid value found is trended, up to and including the start of the interval.

Historical Modes


Then...

Avg The average of all valid data found during the interval is trended, starting at the beginning of the interval, 12:00:00.

High The highest valid data point value found during the interval is trended, starting at the beginning of the interval, 12:00:00.

Low The lowest valid data point value found during the interval is trended, starting at the beginning of the interval, 12:00:00

Historical Modes


Then...

Interpolated The data is interpreted by assuming that the line between two values is a straight line. All points along that line are estimated except the starting point and the ending point. Available for Proficy Historian only.

Let's examine an example of a pen configured to display in sample mode. Assume that the following data is available for a pen and the Interval is set to 10 minutes.

Using the above chart, the values are trended as indicated:

Avg – 4.5 is trended from 12:00:00 to 12:10:00.

High – 9.0 is trended from 12:00:00 to 12:10:00.

Low – 0.0 is trended from 12:00:00 to 12:10:00.

The value, 0.0 at 12:00:00 (the start of the interval), is trended for the duration of the interval, from 12:00:00 up to 12:10:00. If 0.0 is not a valid point, then the last valid value found prior to the start of the interval is trended.

You can enter a data source more than once to display data in different modes. For example, if you trend an Analog Input block, you can enter the block twice in the Pens list box: once in Sample mode, and again in Average mode.

NOTE: Sample mode is the fastest mode for displaying historical data. However, the average, high, and low modes may provide more detailed data values for your application.

Defining General Standard Chart Properties

The General tab on the Chart Configuration dialog box lets you specify basic chart properties such as a title and color, as well as scroll and display options. Properties selected from the General tab apply to the entire chart.

The following sections describe these properties:

• Naming a Chart

• Entering a Chart Description

• Attributing a Help Context ID

• Scrolling a Chart

Naming a Standard Chart

The Name field allows you to enter a specific name for your chart. When you initially add a chart to your picture, the default name appears as Chart1. To change the name, enter an alternate name in the Name field.

Entering a Standard Chart Description

The Description field allows you add a description for your chart. This can be any name that will help you identify the purpose of the chart.

Attributing a Help Context ID

If you have created your own help files, you can attribute a help context ID by entering a value in the Help Context ID field. When you switch to the run-time environment, you can select the chart and press F1 to get help on the chart.

For more information on creating help files, refer to the Creating the Help File section of the Mastering iFIX manual.

Scrolling a Standard Chart

The first thing you must do in order to scroll a chart is determine the direction of the scroll. The scroll direction determines whether the data on the chart plots left-to-right or right-to-left. You can specify a scroll direction for the chart by selecting the appropriate option button in the Scroll Direction area of the General tabbed page.

The following figure illustrates a chart configured with both a real-time and historical pen, with a right-to-left scroll.

For a left-to-right scroll, you can also assign a reset value by entering a value in the Reset field. When the data plot reaches the right edge of the chart, a reset occurs and the pen fetches new data. The data and its time shifts according to the reset percentage. For example, if you enter a reset value of 50, the data plot will shift back one-half of the chart's time axis when it hits the right edge.

To scroll the chart, use the Historical Dynamo, available in the Dynamo Sets folder in the Proficy iFIX WorkSpace system tree. To use the Historical Dynamo, add the Dynamo to your picture and double-click it. The Chart Configuration dialog box appears, which lets you make changes to the chart's properties. Click the Left and Right arrows on the bottom-left and bottom-right of the chart to scroll the chart in a particular direction.

NOTE: The Quick Dynamo Updater and Dynamo Updater Wizard are not available for the Chart Dynamo, and other pre-canned Dynamos that were available before iFIX 4.5. This is because they are not true Dynamo objects.

You can also configure AutoUpdate to scroll the chart forward automatically.

You can change the chart's scroll percentage using VBA scripts. For more information on using scripts to scroll charts, refer to the Writing Scripts manual.

Plotting Ideal Curves

A chart's left-to-right scrolling functionality helps you easily determine how close your data is to a desired value. It does so by letting you easily recognize ideal and actual curves in the same chart. An ideal curve is an existing historical plot that represents an ideal condition in your process. The actual curve is a real-time plot that represents current conditions. Depending on your process, it may be crucial that the actual curve come as close as possible, if not exactly match, the ideal curve.

For example, let's say you want to plot real-time data so that it shows the proper variation in temperature of a process, determined by a plot collected previously. Using multiple pens and scrolling in iFIX charts, you can view the real-time and historical data simultaneously to determine whether data that is currently being fetched matches the ideal scenario.

First, configure both a real-time and a historical pen. Then, for example, assign a green color property for the real-time pen, and a red color property for the historical pen.

Then specify a left-to-right scroll with a reset value of 50. When you switch to the run-time environment, you can watch the real-time pen follow the ideal curve. When the data reaches the right edge of the chart, the data is reset and the plot resumes in the middle of the graph. You do not have to manually position, change the shape of the chart, or leave the run-time environment.

Thanks to the real-time monitoring of all types of data in a scrollable format, iFIX charts give you the ability to monitor crucial fluctuations in data, which, in many cases, can greatly impact your process. The following figure illustrates a chart plotting both a real-time and historical pen with a left-to-right scroll. Notice how easy it is to evaluate the ideal curve.

Scroll direction also appears in the Chart Preferences tabbed page of the User Preferences dialog box. If you change the scroll direction in Chart Preferences, you change the default value for all new charts. To access this dialog box, select User Preferences from the WorkSpace menu (Classic view) or on the Home tab, in the WorkSpace group, in the Settings list, click User Preferences (Ribbon view), and click the Chart Preferences tab.

For more information on the User Preferences dialog box, refer to the Setting User Preferences section of the Understanding iFIX manual.

Changing the Appearance of a Standard Chart

You can easily change how a chart looks by selecting specific properties in the Chart Configuration dialog box. These can include attributes such as color, refresh rate, and transparency, or pen styles such as a marker type.

The following sections describe how to change the appearance of a chart by modifying many of the available chart and pen properties:

• Changing a Chart's Foreground or Background Colors

• Changing the Refresh Rate

• Defining Pen Styles

• Defining Time Ranges

• Configuring the X and Y Axis

• Defining a Grid

• Configuring the Legend

Changing a Standard Chart's Foreground or Background Colors

A chart object is comprised of two rectangular areas: the chart area (where the trends are drawn), and the area around the chart. You can select or change the color of the foreground or background colors using the General tab on the Chart Configuration dialog box. To do this, click either the Foreground Color or Background Color field in the Appearance area and select a color from the Select Color dialog box.

We offer the following recommendations for choosing your colors:

• Use darker colors for the background and a lighter color for the foreground, so that the chart data in the foreground is easier to read.

• Apply a dark pen line color that contrasts well with yellow, so that you can easily read the data on a tool tip in the run-time environment. (The tool tip appears as a yellow box.) Refer to the Displaying Time Cursors and Tool Tips section for information on the tool tip feature.

• Create a transparent chart. The following section shows you how to apply the transparency property to your chart.

For more information on this dialog box and the different ways you can color objects, refer to the Working with Color section in the Creating Pictures manual.

Making the Chart Transparent

A transparent chart is clear, allowing objects displayed behind the chart to be visible. By clicking the Transparent check box in the Appearance area, you instantly create a gray-on-white transparent chart, with a red legend, X and Y axes, data source, and description.

The figure that follows illustrates a transparent chart.

The Transparency property also appears in the Chart Preferences tabbed page of the User Preferences dialog box. To enable or disable the Transparency property for all new charts, select or deselect the Transparent check box. To access the Chart Preferences dialog box, select User Preferences from the WorkSpace menu (Classic view) or on the Home tab, in the WorkSpace group, in the Settings list, click User Preferences (Ribbon view), and click the Chart Preferences tab.

Changing the Refresh Rate

The refresh rate determines how quickly a chart updates the data plot in the run-time environment. The faster the refresh rate, the slower your performance will be, as the chart needs to be redrawn each time it is refreshed at the specified refresh rate.

You can specify a refresh rate for your chart by entering a rate, in seconds, in the Refresh Rate field. The refresh rate can be from 0.1 seconds to a maximum of 1800 seconds, and can be entered in 0.1 second intervals.

Defining Pen Styles

iFIX lets you determine how the pens in your chart look, giving you complete control over the appearance of your chart.

On the Pen tabbed page of the Chart Configuration dialog box, you can define the following pen styles:

• Line Style – Applies a style to the pen's plot line.

• Line Color – Applies a color to the pen's plot line.

• Line Width – Specifies the width of a pen's plot line.

• Marker Style – Applies a style to the pen's marker type.

Each of these styles is described in the following sections.

Applying Line Styles

With iFIX, you can use any line style that you use in any other object. To apply a line style, simple select it from the Line Style drop-down list. Available line styles are:

• Solid – Applies a solid pen line style.

• Dash – Applies a dashed pen line style.

• Dot – Applies a dotted pen line style.

• DashDot – Applies a dash-dot combination line style.

• DashDotDot – Applies a dash-dot-dot combination line style.

The following figure illustrates each of these line styles in a chart.

Selecting a Line Color

To select a line color for a pen, click the Line Color field and choose a color from the Select Color dialog box. Line colors also apply to the X and Y-axis and to the legend. For more information on using this dialog box, refer to the Working with Color section of the Creating Pictures manual.

Selecting a Marker Style

In the Marker Style field, you can select a shape or character to represent the pen marker in your chart. Markers are particularly useful for printing to a black and white printer. Using the drop-down menu, you can select from the following marker styles:

• None – Applies a solid line marker to the pen.

• Rectangle – Applies a rectangle marker to the pen.

• Oval – Applies an oval marker to the pen.

• Diamond – Applies a diamond marker to the pen.

• Character – Applies a character to represent a pen marker. If you select this option, the character field to the right of the Marker Style drop-down list is enabled. Enter any alphanumeric keyboard character in the field.

Defining Time Ranges

Using the Time tab of the Chart Configuration dialog box, you can assign a time range to each pen in the chart. This allows you to compare data from different time periods on the same chart, which in turn aides in plotting ideal curves versus actual curves. You can specify one global time period for all pens in a chart, or select a separate time period for each pen.

To define time ranges, click the Time tab and enter the time ranges in the appropriate fields on the Time tabbed page. Refer to the following table for the correct entry and format for each field.

Time Range Fields and Formats

In the field...

Enter... In the format...

Fixed Date A specific date on which to start the display.

MM/DD/YYYY (month/day/year)

Days Before Now

The number of days prior to today to start the display. For example, if you want to define a time group to display data collected two days before the current date, enter 2.

999 (maximum value)


In the field...


Fixed Time A specific time to start the display, based on a 24-hour clock. For example, enter 14:00:00 for a starting time of 2 P.M.

HH:MM:SS (hour:minutes:seconds)

Lock Time Locks the current time, even if you change the time zone in the Date and Time Properties dialog box in the Control Panel. This field is only available when you designate a specific time to start the display using the Fixed Time field.


In the field...


Duration Before Now

The duration prior to the current time to start the display. The minimum duration for a display is 0 seconds; the maximum is 23 hours, 59 minutes, and 59 seconds.

HH:MM:SS


In the field...


Time Zone The time zone to associate with the start time. You can select an explicit time zone, the client time zone, the server time zone, or the tag time zone. The default time zone is that of the client machine. This field is only available when Proficy Historian is being used.


In the field...


Adjust for Daylight Savings Time

Adjusts the time when the zone you selected is experiencing daylight saving if you selected the Automatically adjust clock for daylight saving changes check box in the Control Panel. This field is only available when Proficy Historian is being used.

NOTE: Before allowing automatic Daylight Saving Time to be used in a production environment, you should test your application for proper behavior.


In the field...


Duration The duration for the display, which determines how much data to display on the X axis. The minimum duration for a display is 1 second; the maximum is 99 days, 23 hours, 59 minutes, and 59 seconds. Using Proficy Historian, the minimum duration for a display is 1 second; the maximum is 365 days, 23 hours, 59 minutes, and 59 seconds. The span duration also appears in the Chart Preferences tabbed page of the User Preferences dialog box.NOTE: The Duration must be evenly divisible by the Interval or unpredictable results may occur in the chart. The Chart tab does not allow you to configure a duration that is not evenly divisible by the Interval.

Days: DD

Time: HH:MM:SS


In the field...


Span Interval

A time interval between the samples taken from the Historical Collect data file. The interval cannot be greater than half the Duration value.

When the Span Interval is 0, the time interval between data samplings is determined automatically based on the span duration divided by the maximum number of display points.

The span duration also appears in the Chart Preferences tabbed page of the User Preferences dialog box.

You can display milliseconds only if you are using Proficy Historian.

NOTE: The Span Duration must be evenly divisible by the Span Interval.

Time: HH:MM:SS

Time (with milliseconds): HH:MM:SS:MS

You can also dynamically change the limits of the time axis using a VBA script that changes in the Start Time and End Time properties of a chart. To enable this feature, select the Allow Reset of Axis Limits check box on the X-Axis tab. When you select this control, you enable the time axis to be reset after you right-click to zoom out in a chart. If you want to configure all charts to behave this way, select the Allow Time Axis Reset check box in the WorkSpace's user preferences.

To apply a global time period to all pens in a chart, select the Apply to All Pens check box. For more information on applying properties to all pens, refer to the Applying Properties to all Pens section.

Configuring the X and Y Axis

iFIX charts allow you to configure both the X (horizontal) and Y (vertical) axis so that you can customize your display. For example, let's say you want to plot an Analog Input block, AI1, with values ranging from 0 to 100 with a one-minute duration (represented as a red pen line with a rectangle marker). You also want to plot another Analog Input block, AI2, with values from 0 to 200 with a two-minute duration (represented as a blue pen line with an oval marker). You can view both plots at the same time and, if the chart is selectable, you can switch between pens by either clicking the plot line or by clicking the text in the legend. This is illustrated in the following figure.

You can configure an axis by clicking the X-axis or Y-axis tab. On both tabs you can choose whether to display the axis or axis labels, and you can specify the title name, the axis color, and the number of labels and ticks. For the X axis, you can also select whether to display the date.

To specify a title name, enter a title of up to 255 characters in the Title field. To specify a color, click the Label Color field and select a color from the Select Color dialog box.

To specify the number of labels in your chart, enter a number in the Number of Labels field. The maximum number of labels you can have is 21. Similarly, to specify the number of ticks per axis, enter a number in the Number of Ticks field. The maximum number of ticks you can have is 21.

The default values for ticks and labels appears in the Chart Preferences tabbed page of the User Preferences dialog box.

Defining a Grid

The grid in your chart gives you a point of reference when data points move across the chart. iFIX gives you precise control of both the horizontal and vertical axis of your grid. To define a grid, click the Grid tab. Both the Show Horizontal Grid and Show Vertical Grid areas let you select whether to display the grid, the number of lines in the grid, and the grid color and style. For the horizontal axis, you can also select whether to scroll the grid when you select a scrolling option.

To select a number of lines for the grid, enter a number in the Number of Lines field. The maximum number of lines you can have in your grid is 21. To select a color for your grid, click the Grid Color field and select a color from the Select Color dialog box.

To select a grid style, select a style from the Grid Style drop-down list. You have the same types of styles for your grid as you do for your pen line styles (Solid, Dashed, Dotted, Dash-Dot, and Dash-Dot-Dot).

Configuring the Legend

The legend lets you quickly identify the information that the chart is plotting. The legend appears at the bottom of the chart and provides collection and error information for each trended data source. Each legend displays in the pen color assigned to the pen's data source. To configure a legend, click the Legend tab on the Chart tabbed page of the Chart Configuration dialog box.

You can modify the legend to appear in various configurations. For example, if you want to change the length of the data source description, select the Description check box in the Items area and enter the number of characters that represents the length of the description. To change the order of the pens in the chart's legend, click the pen you want to move in the Pen List area, and then click either the up or down arrow.

To configure the legend, click the Legend tab and select or deselect the properties of the legend. The Order area of the Legend tab lets you display the items you select in any order in the legend (left to right).

Animating Chart Properties

Chart properties can be animated just like other iFIX objects. For example, you can animate the chart's foreground color, pen color, and value axis. To animate chart properties, right-click the chart and select Animations from the pop-up menu. The Animation dialog box lets you change property settings and add animations to those properties.

For more information on animating object properties, refer to the Animating Object Properties chapter of the Creating Pictures manual.

Working in the Run-time Environment

To view the data in a chart, click the Switch to Run button on the Standard toolbar (Classic view) or on the Home tab, in the WorkSpace group, click Switch to Run (Ribbon view). In order to control your charts in the run-time environment, you must assign specific attributes in the configuration environment.

These attributes are detailed in the following sections:

• Defining Run-time Attributes

• Zooming

• Displaying Multiple Values and Times

• Displaying Time Cursors and Tool Tips

• Understanding Chart Time

• Adjusting for Daylight Saving Time

Defining Run-time Attributes

You can assign certain attributes in the configuration environment to make the chart accessible when you switch to the run-time environment. You can specify these attributes by selecting the appropriate check boxes on the General tabbed page of the Chart Configuration dialog box. Refer to the following table:

Chart Attributes

By selecting the check box...

You activate the property...

Which lets you...

Highlightable IsControllable Highlight the object at run-time so it can be modified.

Example: Determine which object in a picture can be selected or modified.

Selectable IsSelectable Select the object at run-time.

Examples: Zoom in on an area of the chart; display a time cursor tool tip on a pen.

Modifiable IsModifiable Modify the object at run-time.

Example: Modify pen properties using the Chart Configuration dialog box.

Zooming

When a chart is selectable, you can zoom to an area of the chart by placing the cursor within the chart area and clicking an area, or enclosing an area in a rectangle selector. When the cursor is in the chart area, it becomes a magnifying glass. You can zoom to the horizontal, vertical, or both axes in the chart to view specific data. To zoom out on the chart, right-click the mouse while the cursor is in the chart area.

Depending on the options you enabled, the chart is restored to its original magnification or to the magnification set by the HiLimit and

LoLimit properties (on the Y-axis) and the Start Time and End Time properties (on the X-axis). The following table summarizes the options to set or clear to achieve the effect you want.

To... Do this...

Restore the chart to its original magnification.

Clear the following check boxes:

• Allow Reset of Axis Limits (on the x-axis and y-axis tabs of the Chart object).

• Allow Time Axis Reset (on the Chart Preferences tab of the User Preferences dialog box).

• Allow Value Axis Reset (on the Chart Preferences tab of the User Preferences dialog box).

Reset the range of the time axis to the Start Time and End Time properties.

Select one of the following check boxes:

• The Allow Reset of Axis Limits check box (on the x-axis tab of the Chart object).

• The Allow Time Axis Reset check box on the Chart Preferences tab of the User Preferences dialog box.

Reset the range of the value axis to the HiLimit and LoLimit properties.

Select one of the following check boxes:

• The Allow Reset of Axis Limits check box (on the y-axis tab of the Chart object).

• The Allow Value Axis Reset check box on the Chart Preferences tab of the User Preferences dialog box.

Displaying Multiple Values and Times

In your chart, you may have pens with different high and low limits and time scales. You may want to see these differences in the run-time environment. By default, iFIX lets you view a given pen's value and time axis by clicking the pen line, clicking the pen's legend, or setting the current pen using VBA scripts.

If you don't need to view the value of a specific pen, select the Show Multiple Values check box on the General tabbed page. The chart will be displayed with all of the pen's axes in a stacked fashion. Similarly, if you wish to view specific time scales for your pens, deselect the Show Multiple Times check box. To view multiple time scales, select the Show Multiple Times check box.

The following figure illustrates a chart with two pens configured with different time and value ranges and their axes.

Displaying Time Cursors and Tool Tips

In iFIX you can choose to display time cursors in the run-time environment. The time cursor appears as a gray bar in the center of the chart that you move left and right by clicking the cursor and dragging it with the mouse. The value of the time cursor is displayed in the legend. For historical pens, the value at the point of the time cursor is displayed; for real-time pens, the current value is always displayed.

To display the time cursor in the run-time environment, select the Show Time Cursor check box on the General tabbed page.

Another run-time feature of charts is the time cursor tool tip. When you click on a point in a pen line where that line crosses the time cursor, the current time and value of that point is displayed in a yellow-colored box. The tool tip is a convenient way to determine plot values in the run-time environment. Every pen in the chart has its own tool tip. To display the tool tip in the run-time environment, select the Show Time Cursor ToolTips check box on the General tabbed page.

NOTE: The chart must be selectable to view the time cursor and tool tip at run-time.

The following figure illustrates a chart configured with two real-time pens, a time cursor, and tool tip for each pen.

Understanding Standard Chart Time

The following fields affect the time displayed in the chart when you use a fixed start time and date:

• Lock Time

• Time Zone (Proficy Historian only)

• Adjust for Daylight Savings Time (Proficy Historian only)

iFIX charts save time as Coordinated Universal Time (or UTC time). When you switch to the run-time environment, UTC time is read from the picture file containing the chart, and is then converted to local time before the chart fetches data from the historical file. Therefore, when you configure a chart, time is entered and displayed in local time. However, the time saved within the chart is in UTC time, which allows the data to be displayed independently of specific time zones.

The following examples help explain the concept of using time zones and daylight saving.

Example 1: No Features Enabled

In this example, pictures are created and saved in Eastern Standard Time (EST). The Fixed Time is set to 09:00:00, the Duration Before Now is set to 01:00:00, and Days Before now is set to 0.

You get these results when you open the picture in the indicated time zone:

EST – displays data from 9:00 to 10:00 a.m.

CST – displays data from 8:00 a.m. to 9:00 a.m. local time.

Example 2: Lock Time Feature is Enabled

In this example, pictures are created and saved in EST. The Fixed Time is set to 09:00:00, the Lock Time is selected, the Duration Before Now is set to 01:00:00, and Days Before now is set to 0. You get these results when you open the picture in the indicated time zone:

EST – displays data from 9:00 to 10:00 a.m. local time.


Example 3: Developing for Remote Deployment (Proficy Historian only)

When you use the Time Zone and Adjust for Daylight Savings Time fields, the pictures you create are independent of the time zone in which you draw them. This independence gives you more control of the behavior of a picture when it is opened.

In this example, pictures are created and saved in EST, but deployed to a computer in Pacific Standard Time (PST). If you want the picture to show 9:00 a.m. to 10:00 a.m. PST when opened, you must select the explicit PST time zone in the Chart tab and set the start time to 9:00 a.m. You must also select Lock Time check box.

If your plant policy is to automatically adjust for Daylight Saving Time and you have selected Automatically Adjust for DST in the Control Panel time settings, then you should select the Adjust for Daylight Savings Time check box in Chart tab.

Example 4: Developing for Multiple Time Zone Deployment (Proficy Historian only)

You can share pictures across time zones by using the client time zone setting in the Chart tab.

In this example, pictures are created and saved in EST, but deployed to a computer in EST in the client time zone. The Lock Time is selected. When the picture is opened in CST, PST, or EST, it is always displayed as 9:00 a.m. local time.

Example 5: Using Server Time Zone (Proficy Historian only)

A picture configured to use the server time zone can be opened on any client machine in any time zone and will always show the same plot of data.

Example 6: Displaying Data from Other Time Zones (Proficy Historian only)

You are investigating an event that occurred at 3:30 Central Standard Time (CST) and your computer is in PST. Rather than open a chart with a 1:30 start time in PST, you can select the explicit central time from the Time Zone field and set the Fixed Time at 3:30

Example 7: Displaying Data from Multiple Time Zones (Proficy Historian only)

You have some points in the Proficy Historian archive that contain data from Mountain Standard Time (MST) and some from PST. You want to create a chart to display the events that occurred in each time zone at 10:00 a.m. Rather than being required to know the exact time zone location of each point and then choosing explicit time zones, you can select the tag time in the Time Zone field and set the Fixed Time at 10:00 a.m.

The UTC time feature of iFIX charts allows you to easily view and analyze a data plot, no matter where you display the data.

Adjusting for Daylight Saving Time

If you are a Proficy Historian user, you have the option to adjust for daylight saving time. If you choose to adjust for daylight saving time, you must:

1. Select the Automatically adjust clock for daylight saving changes check box in the Date/Time section of the Control Panel on all Proficy Historian collector, Proficy Historian server, and iFIX client computers.

2. Select the Adjust for Daylight Savings Time check box on the Time tab when you add an historical pen to an iFIX chart.

Before allowing automatic Daylight Saving Time to be used in a production environment, you should test your application under each of the following scenarios for proper behavior:

• While in Standard Time.

• While in Daylight Time.

• During the transition from Standard Time to Daylight Time.

• During the transition from Daylight Time to Standard Time.

Working with Enhanced Charts

The following sections describe how to modify many of the properties of an Enhanced Chart:

• Enhanced Chart Types

• Working with Enhanced Chart Properties

• Changing the Appearance of an Enhanced Chart

• Working in the Run-time Environment for Enhanced Charts

• Performance Considerations and Limitations for Enhanced Charts

• Exporting Data from an Enhanced Chart

Enhanced Chart Types

There are four types of enhanced charts. They include statistical process control charts, histograms, line/multiline charts, and XY charts. The following sections describe each chart in detail:

• Statistical Process Control Charts

• Other Types of Enhanced Charts

Statistical Process Control Charts

Enhanced charts offer the ability to add statistical process control charts to your pictures. The charts use the Statistical Data database block type SD. These blocks collect data according to how you configure them, and display the collected data in run mode.

The number of samples and other parameters are configured in the block, not through the WorkSpace. Refer to the Database Block Reference for more information on configuring Statistical blocks.

When you configure a data source for a statistical process control chart, you can only use statistical data tags. If you add a data source using the Expression Builder, only statistical data tags are available for selection. Similarly, if you choose to enter your data source directly in the Data Sources list of the expression editor and it is not a statistical data tag, you will receive an error message.

The statistical charts provide graphical data of key Statistical Data tag calculations. There are three statistical process control charts, which are X-Bar, R-Bar, and S-Bar.

Understanding X-Bar Charts

The X-Bar chart shows how the mean (or average) changes over time. This chart is used to analyze central location; that is, the center of a set of sample data. The statistic used to describe the central location is the mean.

Data for the X-Bar chart can be derived from subgroups of constant size or variable sizes.

X-Bar Chart

The average over time

The Upper and Lower Warning Limits

The Upper and Lower Control Limits

Understanding R-Bar Charts

An R-Bar chart shows the range of the data. When creating statistical data, R is the range of the data; that is, the highest observed value minus the lowest. R-Bar is the average of the ranges for the subgroups collected.

R-Bar Chart

The average of the ranges of the data for all subgroups


Understanding S-Bar Charts

The S-Bar chart shows the standard deviation of the process, where S represents the standard deviation of the process data, and the S-Bar represents the average of the standard deviations for the subgroups.

S-Bar Chart

The average of the standard deviations for all subgroups


Other Types of Enhanced Charts

Other than the statistical process control charts, iFIX offers three other types of Enhanced charts. They are the histogram, line/multiline, and XY charts.

Each chart provides you with a particular way to visualize your data. Histograms show the distribution of a DataSet, while an XY chart illustrates the relationship between DataSets. Line/Multiline charts can help you visualize a trend in your data over time.

Data Sources and Chart Types

Each type of chart requires that you use a particular database block type, as detailed in the following table:

Chart Type Database Block to Use

Histogram HS

Line/Multiline Any

XY Any block, except SD, HS, ETR, SQT, SQD, or PA

These blocks collect data according to how you configure them, and display the collected data in run mode. The number of samples and other parameters are configured in the block, not through the WorkSpace. Refer to the Database Block Reference for more information on configuring these blocks.

When you configure a data source for an Enhanced chart, you must use the appropriate tags. If you add a data source using the Expression Builder, only the appropriate tags are available for selection. Similarly, if you choose to enter your data source directly in the Data Sources list of the expression editor and it is not the correct type of tag, you will receive an error message.

Understanding Histograms

A Histogram chart (also referred to as a Normal chart), is a bar graph that shows the distribution of a DataSet.

The Histogram graphically shows the following:

• Center of the data – which is measured by mean, median, and mode.

• Spread of the data – how different the values are from the each other and from the middle.

• Presence of outliers – outliers are points on a chart that do not fall into the pattern.

• Presence of multiple modes in the data – the shape of the histogram may reveal multiple `peaks'.

Understanding Line/Multiline Charts

A line/multiline chart displays a trend in data over intervals of time. It can display historical and real-time data.

Line/Multiline Chart

If you choose to use a real-time data source for your line/multiline chart, be aware that when you view it in run mode, the first data points will not be plotted until the time specified in the Chart Update Rate on the General tab of the Enhanced Chart Configuration dialog box has elapsed. Therefore, there will be a lag time between when you open the chart in run mode and when the data is plotted; the first data point does not immediately display. This applies to tag group substitution, as well.

Understanding XY Charts

An XY chart allows you to visualize how two or more types of data, such as temperature and pressure, are affected by one another. Using the chart, you can determine the type of relationship between two DataSets.

In XY charts, you can use either real-time data or historical data, but not both on the same chart. The data is refreshed and plotted based on the settings for the X-axis.

XY Chart

The axis used as the data source is underlined in the data source legend. In the preceding illustration, the Y axis is underlined, which indicates that the second data source added during configuration of the XY chart was selected for the horizontal axis.

If you choose to use a real-time data source for your XY chart, be aware that when you view it in run mode, the first data points will not be plotted until the time specified in the Chart Update Rate on the General tab of the Enhanced Chart Configuration dialog box has elapsed. Therefore, there will be a lag time between when you open the chart in run mode and when the data is plotted; the first data point does not immediately display. This applies to tag group substitution, as well.

Working with Enhanced Chart Properties

The following sections describe how assign specific properties to Enhanced Charts:

• Applying Enhanced Chart Properties

• Naming an Enhanced Chart

• Entering an Enhanced Chart Description

• Defining Data Sources for Enhanced Charts

Applying Enhanced Chart Properties

There are several ways you can apply selected properties to your charts using the Chart Customization dialog box:

• Select a new data set in the Data Sources list.

• Click OK.

• Click Apply.

• Select the Apply to All Data Sources check box.

Each of these methods are described in the following table.

Methods of Applying Properties

Use this method...

To...

Select a new data source in the Data Source list

Automatically apply properties based on the selected data source. This method takes precedence over other methods of applying properties: you do not have to click OK or Apply to apply the data source property, and, if you click Cancel after you have selected a data source, the properties are still applied.

Click OK Quickly apply selected properties to your chart and close the Chart Customization dialog box.

No matter which method you use to apply properties, you must click OK to close the dialog box.

Click Apply

View a property change immediately without closing the Chart Customization dialog box. For example, if you want to change the color of a chart, change the color and click Apply. The color of the chart will change while the Chart Configuration dialog box stays on your screen.

You are not required to click Apply to apply properties to your chart.

Select the Apply to All Data Sources check box

Apply properties to all data sources added to a chart. Refer to the Applying Properties to All Data Sources section below for more information.

NOTE: The Apply to All Data Sources check box applies only during the current configuration session. The default (that is, the check box is cleared) is restored the next time you open the Chart Configuration dialog box.

Applying Properties to all Data Sources

iFIX allows you to easily define time, X and Y axis, grid, and legend properties for every data source you add to your chart. You can do this by simply selecting the Apply to All Data Sources check box on the Time tab on the Data Sources tab. For example, you may want all of the data sources in your chart to have the same legend.

To accomplish this, click the Legend tab and select the properties you want. Next, select the Apply to All Data Sources check box. Exit the dialog box by clicking OK.

Naming an Enhanced Chart

The Name field allows you to enter a specific name for your chart. To change the name, enter an alternate name in the Name field.

Entering an Enhanced Chart Description

The Description field allows you add a description for your chart. The description is a VBA property and can be any name that will help you identify the purpose of the chart.

Defining Data Sources for Enhanced Charts

One of the most dynamic features of charts is the integration of both real-time and historical data in the same chart, which lets you easily view all types of data in the Proficy iFIX WorkSpace. You need to define the data sources you want to trend.

The following sections show you how to select a data source and configure its properties.

Adding Data Sources to Your Chart

Each data source must be defined. At the top of the Data Sources tab of the Chart Customization dialog box is the Data Sources List area, which lists the data sources in Data Server.NODE.TAG.FIELD format.

NOTE: If you are adding a data source to an SPC (X-Bar, R-Bar, or S-Bar) Chart, you must use the SD block. For a histogram, you must use the HS block. For XY charts, you can use any block except SD, HS, ETR, SQT, SQD or PA.

There are many ways to add a new data source to your chart:

• Click Add in the Data Sources List area, and enter a data source in the field that appears.

• Double-click a blank field in the Data Sources List and enter a data source in the field.

• Click the Browse button to the right of the field to display the Expression Builder, which allows you to search for global data sources through a data source browser. To learn how to use the Expression Builder and define data sources, refer to the Animating Object Properties chapter in the Creating Pictures manual. For more information on data sources, refer to the System Architecture section of the Understanding iFIX manual.

• Write a VBA script. Refer to the Writing Scripts manual for more information.

For XY charts, you can only add two data sources, one for the X-axis and one for the Y-axis.

To modify an existing data source in the Data Sources list, double-click the data source and enter an alternate data source. To change the order of the data source in the chart's legend, click the data source you want to move in the Data Sources List area, and then click either the up or down arrow.

To delete a data source, select the data source from the list and click the Delete button.

Defining Data Properties

To control how the data is presented by the configured data source(s), you can define the data properties for your chart. You can do this by selecting the properties you want on the Data tab on the Data Sources tab. The following properties can be defined:

• High Limit – Displays the high limit value defined for the selected data source.

• Low Limit – Displays the low limit value defined for the selected data source.

• Fetch Limits – At run-time, automatically retrieves the low and high limits assigned to the selected data source. If this option is selected, then the manually entered High and Low Limits will not be considered.

• Show Gaps – Determines whether a blank space or a line is displayed to represent an area in a plot where there is no data. This field is not available for XY charts.

• Interpolate Data – Causes the lines between plotted data to display as slopes, rather than flat lines. This field is not available for XY charts.

• Maximum Display Points – Determines how many data points will be displayed for the data source over a given span duration. This field is not available for XY charts.

• Auto Adjust Interval – Causes the intervals to automatically adjust, resulting in evenly spaced data display. This option is automatically selected. For Trend mode and for XY charts, this option cannot be disabled. In addition, for XY charts, this field is not displayed.

• Historical Mode – Determines how iFIX selects data from a historical data source and displays it in the chart, and determines what each displayed value represents. This field is not available for XY charts.

The following table provides some examples of data properties applied to a chart.



To...

High Limit

Low Limit

Specify high and low limit values for trending. To do this, enter the low and high limit values you want to trend for the selected data source in the Low Limit and High Limit fields, respectively.



To...

Fetch Limits Retrieve the limit range assigned to the data source at run time. For example, you may have a data source with limits that are unknown or prone to change in the configuration environment.

By selecting Fetch Limits, you can set the data sources high and low limits equal to that of the data source at run time.



To...

Maximum Display Points

Determine how many data points display for the data source in the chart based on a set duration.

For example, if the maximum points are 500, and the duration is 500 seconds, then the maximum number of points that the chart will maintain is 1 per second.



To...

Auto Adjust Interval

Avoid having data points interpolated. With this option, the chart automatically calculates the interval required to return a sample size equal to the number of chart points thus avoiding interpolation, missing intervals and gaps in the data.

Selecting a Historical Display Mode

NOTE: This feature is not available for XY charts. The data is always interpolated.

Data sources displaying historical data offer additional flexibility in how the data is displayed by offering a historical mode, available on the Data tab on the Data Sources tab. Select a mode from the Historical Mode drop-down list. The display mode determines how iFIX selects data from a historical data source and displays it in the chart, and determines what each displayed value represents.

Historical modes are directly related to Span Interval and Span Duration properties for the time group. The Span Interval determines the range of data that the display mode uses to calculate the point of data that is trended. Time group properties are further described in the Defining Time Ranges section.

The following table shows the different historical modes you can choose from, and how trending differs for each mode.

Historical Modes


Then...

Sample The last valid value found is trended, up to and including the start of the interval.

Avg The average of all valid data found during the interval is trended, starting at the beginning of the interval, 12:00:00.

High The highest valid data point value found during the interval is trended, starting at the beginning of the interval, 12:00:00.

Low The lowest valid data point value found during the interval is trended, starting at the beginning of the interval, 12:00:00

Historical Modes


Then...

Interpolated The data is interpreted by assuming that the line between two values is a straight line. All points along that line are estimated except the starting point and the ending point. Simple linear interpolation is used to estimate the line. Available for Proficy Historian only.

Trend The raw data for the minimum and maximum values for each interval is returned.

Let's examine an example of a data source configured to display in sample mode. Assume that the following data is available for a data source and the Interval is set to 10 minutes.

Time Data Value

12:00:00 0.0

12:01:00 1.00

12:02:00 2.00

12:03:00 3.00

12:04:00 4.00

12:05:00 5.00

12:06:00 6.00

12:07:00 7.00

12:08:00 8.00

12:09:00 9.00

Using the above chart, the values are trended as indicated:

Avg – 4.5 is trended from 12:00:00 to 12:10:00.

High – 9.0 is trended from 12:00:00 to 12:10:00.

Low – 0.0 is trended from 12:00:00 to 12:10:00.

The value, 0.0 at 12:00:00 (the start of the interval), is trended for the duration of the interval, from 12:00:00 up to 12:10:00. If 0.0 is not a valid point, then the last valid value found prior to the start of the interval is trended.

You can enter a data source more than once to display data in different modes. For example, if you trend an Analog Input block, you can enter the block twice in the Data Sources List: once in Sample mode, and again in Average mode.

NOTE: Sample mode is the fastest mode for displaying historical data. However, the average, high, and low modes may provide more detailed data values for your application. The trend mode is the preferred mode for retrieving data for plotting over long time periods.

Understanding Enhanced Chart Data Source Limits Symbols

In Enhanced Charts, if the values for the data source limits are particularly large or small, symbols are used to represent the value and are substituted for zeros. This minimizes the area required for labels and increases the chart display area. For example, in the following figure, the values for the axes are followed by a "B", indicating that the values are in the billions. The "B" replaces the nine zeros.

Scrolling an Enhanced Chart

Plotting Ideal Curves

A chart's left-to-right scrolling functionality helps you easily determine how close your data is to a desired value. It does so by letting you easily recognize ideal and actual curves in the same chart. An ideal curve is an existing historical plot that represents an ideal condition in your process. The actual curve is a real-time plot that represents current conditions. Depending on your process, it may be crucial that the actual curve come as close as possible, if not exactly match, the ideal curve.

For example, let's say you want to plot real-time data so that it shows the proper variation in temperature of a process, determined by a plot collected previously. Using multiple data sources and scrolling in iFIX charts, you can view the real-time and historical data simultaneously to determine whether data that is currently being fetched matches the ideal scenario.

iFIX charts give you the ability to monitor crucial fluctuations in data which, in many cases, can greatly impact your process.

Scrolling an Enhanced Chart

To scroll an enhanced chart, use the Historical Line Chart Dynamo, available in the Dynamo Sets folder in the Proficy iFIX WorkSpace system tree. Add the Dynamo to your picture and double-click it. The Historical Line Chart Customization dialog box appears, which lets you make changes to the chart's properties.

The following figure illustrates the controls available for date and time selection, as well as scrolling, in the Historical Line Chart Dynamo.

iFIX Historical Line Chart Dynamo

Fast Backward – Scrolls the chart back 50% of the chart's duration

Backward – Scrolls the chart back 25% of the chart's duration

Date Picker – Allows you to specify the date of the historical data

Time Picker – Allows you to specify the time of the historical data

Forward – Scrolls the chart forward 25% of the chart's duration

Fast Forward – Scrolls the chart forward 50% of the chart's duration

Chart Configuration Considerations

There are some considerations to keep in mind when configuring the Historical Line Chart Dynamo.

• If you want to use a key macro, or a click event for the Historical Line Chart Dynamo, clear the Selectable checkbox on the General tab on the Historical Line Chart Customization dialog box. Otherwise, when you click on the Dynamo in run mode, the key macro or click event does not work properly, because only the chart is selected, not the entire Dynamo. If you choose to leave Selectable enabled, then make sure to add your key macros and click script events to both the line chart and Dynamo objects.

• The Days Before Now and Duration Before Now fields, which are located in the Start Time area of the Time tab, of the Data Sources tab, on the Historical Line Chart Customization dialog box, are disabled. Any entry you make in these fields is disregarded.

• However, you can use the Fixed Date and Fixed Time fields of the first data source listed in the Data Sources list to set the start date and time. The Fixed Date and Fixed Time used for the first data source in the Data Sources list applies to all data sources, causing all data sources to start on the same date and time on the chart.

IMPORTANT: Do not disable FixedDate and FixedTime in the Property Window or in VBA. If you disable them, the chart will not work correctly.

• The initial date and time that appear on the chart in run mode are based on the start date and time configured in the Start Time area on the Time tab of the Data Sources tab for the first data source listed in the Data Sources list.

• While in configuration mode, if you use a method other than completing the Line Chart Customization dialog box to set the start date and time in the Date and Time Picker fields, when you switch to run mode, the start date and time on the chart axis will not match the date and time you configured. Instead, they will match the start date and time entered on the Time tab for the first data source in the Data Sources List.

• If you use only real-time data sources, the chart does not scroll.

Using the Historical Line Chart Dynamo

Click the arrows on the bottom of the chart to scroll the chart in a particular direction. Depending on the arrow selected you will move forward or backward either 25 or 50% of the chart's duration. The chart's duration is set on the General tab in the Duration area of the Historical Line Chart Customization dialog box.

You can use the date and time picker to specify exactly where you want your chart to begin. To choose a date, click the Date Picker selection box arrow; on the calendar that appears, click on the desired date. To choose a time, you can either enter the desired time directly in the Time Picker selection box, or use the Time Picker selection box arrows to change the time.

NOTES:

• Changing the time using the Time Picker does not change the date displayed on the Date Picker. So, for example, if you move the time from 11 p.m. to 12 a.m., the date remains the same in the Date Picker; it does not advance one day.

• When running the Historical Line Chart Dynamo with a Historical Update Rate set, the dates and times displayed in the Date and Time Pickers are not automatically updated to reflect the new start time of the chart upon refresh.

IMPORTANT:

• The Quick Dynamo Updater and Dynamo Updater Wizard are not available for the Historical Line Chart Dynamo because it is not a true Dynamo object.

• If you use multiple historical data sources, the time period for the chart is the same for all sources. It is based on the date and time selected using the Date and Time Pickers.

You can change the chart's scroll percentage using VBA scripts. For more information on using scripts to scroll charts, refer to the Writing Scripts manual.

Changing the Appearance of an Enhanced Chart

The following sections describe how to customize the appearance of an Enhanced Chart:

• Adding a Title to an Enhanced Chart

• Changing the Refresh Rate for an Enhanced Chart

• Understanding Refresh Rates for Enhanced Charts

• Configuring the Legends for an Enhanced Chart

• Choosing a Border Style for an Enhanced Chart

• Choosing the Format and Precision of Data to Display for Enhanced Charts

• Defining a Grid for an Enhanced Chart

• Defining Time Ranges for an Enhanced Chart

• Configuring the X and Y Axis for an Enhanced Chart

• Choosing Fonts for Enhanced Charts

• Changing the Color Scheme of an Enhanced Chart

• Defining the Plotting Style for Enhanced Charts

Adding a Title to an Enhanced Chart

Adding a title to your chart will help you to see at a glance what type of information the chart contains.

The Main Title field allows you to enter a specific title for your chart. When you first add a chart to your picture the default title that appears is Chart Type. For example, if you add an X-Bar chart to your picture, the title will read X-Bar Chart. To change the name, enter the desired name in the Main Title field.

Additionally, you can add a subtitle to your chart, for further clarification of the chart information. To add a subtitle, enter it in the Subtitle field on the General tab of the Chart Customization dialog box.

Changing the Chart Update Rate for an Enhanced Chart

The chart update rate determines how quickly a chart updates the data plot in the run-time environment. The faster the chart refresh rate, the slower the performance will be, as the chart needs to be redrawn each time it is refreshed at the specified refresh rate.

You can specify a chart refresh rate for your chart by entering a rate, in seconds, in the Chart Update Rate field, in the Appearance area on the General tab of the Chart Customization dialog box. For real-time data sources, the refresh rate can be from 0.1 seconds to a maximum of 1800 seconds, or 30 minutes, and can be entered in 0.1 second intervals. For historical data sources, the refresh rate can be from 5 seconds to a maximum of 1800 seconds, or 30 minutes.

Understanding Refresh Rates for Enhanced Charts

There are a number of refresh rates that are involved with presenting data on a chart. In order to get the best appearance from your charts, it is necessary to understand how the rates interact.

Type of Refresh Rate

Definition

Block Scan Time

The scan time, or the frequency of the interaction between the PLC and the SCADA.

Real-time Data Refresh Rate

The frequency at which the database updates the information from the block. This rate should not be set to a higher value than the block scan time value. This value is set on the Expression Builder dialog box.

Chart Update Rate

The frequency at which the chart retrieves data from the database. This rate should not be set to a higher value than the real-time data refresh rate. Doing so may result in flat line areas in your chart, because the chart is retrieving data faster than the database is receiving updates. This value is set in the Appearance area of the General tab of the Chart Customization dialog box.

For XY charts, this update rate applies to both real-time and historical data sources.

Historical Update Rate

The frequency at which the chart retrieves historical data from the Historian. This value is completely independent of the other three refresh rates, which are interdependent. Because the historical update rate is independent of the other refresh rates, when historical data is plotted on a chart with real-time data, it will not update in the same way. Its plotting behavior is best exemplified on Standard Charts.

NOTE: This option does not apply to XY charts.

Configuring the Legends for an Enhanced Chart

The legend lets you quickly identify the information that the chart is plotting. In Enhanced Charts, charts may display up to two legends, which include the plotting style and data source legends. To determine which legends appear on your chart, select or clear the legend check boxes in the Miscellaneous area on the Chart Style tab.

Plotting Style Legend

The plotting style legend, if enabled, appears at the top of the chart. For line/multiline charts, the plotting style legend displays the color and point or line type for each data source. For SPC charts, including X-bar, R-bar, and S-bar charts, the plotting style legend displays the color for the data source, the upper and lower control limits, the upper and lower warning limits, and the bar value. For XY charts, the plotting style legend displays the color and point, or line type for the Y-axis data source.

Data Source Legend

The data source legend, if enabled, appears at the bottom of the chart. For line/multiline and XY charts, the data source legend provides collection and error information for each data source. For SPC charts, including X-bar, R-bar, and S-bar charts, in addition to the collection information, the upper and lower control limits, the upper and lower warning limits, and the bar value also appear. To configure the data source legend, click the Data Sources tab on the Legend tabbed page of the Chart Customization dialog box.

You can modify the data source legend. You can add or remove items from the legend, as well as change the order of the items that appear. However, for XY charts, you cannot remove the axis indicators; they are always present. To add or remove items from the chart's legend, click the Legend tab and select or clear the property check boxes of the legend. The Order list of the Legend Column Widths area on the Chart Style tab lets you display the items you select in any order in the legend (left to right).

To change the number of characters permitted for each legend description, change the value in the corresponding field on the Chart Style tab in the Legend Column Widths area.

Choosing a Border Style for an Enhanced Chart

You can choose the type of border you want for your chart. Your selection is applied to both the graph and table.

To choose a border style, make a selection in the Border Style area on the Chart Style tab on the Chart Customization dialog box.

NOTE: Settings chosen on the Chart Style tab override the settings chosen on the Color tab.

Choosing the Format and Precision of Data to Display for Enhanced Charts

With all Enhanced Charts, except for the XY chart, you can choose to display your data in a graph, a table, or both. How you plan to use the data and who is looking at it will determine your choice of format for data display.

You can choose the format for your data in the Display area, on the Chart Style tab on the Chart Customization dialog box.

You can also select a level of numeric precision, or the number of decimal points used for your chart. However, decimal points do not appear on the chart, even if you specify a high level of precision unless they are necessary. You can set the level of numeric precision in the Numeric Precision area, on the Chart Style tab on the Chart Customization dialog box.

Defining a Grid for an Enhanced Chart

The grid in your chart gives you a point of reference when data points move across the chart. iFIX gives you precise control of both the horizontal and vertical axis of your grid. You can select whether to display the grid, which axis to display, whether the grid is in front of the data, and the grid style.

To define a grid, click the Chart Style tab and select the desired options in the Grid Lines area.

Defining Time Ranges for an Enhanced Chart

For historical data sources only, you can assign a time range to data sources in the chart, using the Time tab on the Data Sources tab on the Chart Customization dialog box. This allows you to examine data from a specific period of time.

To define time ranges, click the Time tab on the Data Sources tab and enter the time ranges in the appropriate fields.

NOTE: Time range selection is available only for Line/Multiline and XY charts.

Configuring the X and Y Axis for an Enhanced Chart

You can configure an axis by clicking the Axis tab. There, you can specify the label for both axes.

For the Y-axis, you can set the values including the minimum, maximum, or both, or have iFIX automatically generate the Y-axis range, by selecting the Use Data Source Limits field. If you choose to allow iFIX to auto generate the Y-axis range, you can enter a value in the padding field. This causes the chart to show values that exceeds the maximum and minimum values, thus allowing some padding on either side of the range. The padding is measured as a percentage of the total Y-axis. For line charts only, you can choose to use either linear or log values as the unit of measure. Optionally, you can choose to extend the Y-axis tick marks on the Chart Style tab.

For the X-axis, on the Chart Style tab, you can select the label orientation. The X-axis labels do not reflect the actual time stamp of the data. The X-axis time stamps are calculated based on the duration and/or start time defined for the data source selected for the horizontal axis. The horizontal axis's data source defaults to the one at the top of the list in the Data Sources List field on the Data Sources tab of the Chart Customization dialog box.

In run mode, you can change the data source selected for the horizontal axis by clicking on another data source in the Chart Legend. The actual data time stamps appear in the Time Cursor Legend.

For XY charts, you can configure the X-axis to use either linear or log values as the unit of measure. You can also choose to have iFIX automatically generate the X-axis range, by clearing the Use Data Source Limits check box. If you choose to allow iFIX to auto generate the X-axis range, you can enter a value in the padding field.

Choosing Fonts for Enhanced Charts

You can choose the font type and face to use for your charts. The font size selections you make are applied to all chart items including the title, sub-title, subset, points, axis labels, and table data.

You can also choose the display size of the fonts. However, when choosing a size, keep in mind that the total area available for your chart does not change, even if the font size does. Therefore, the size you choose for the font impacts the available area for chart display. For example, in the following table, the large size font provides much less space on the chart for actual data display, than does the small size font.

For the following chart... the font size selected is...

small

For the following chart... the font size selected is...

medium

large

To make your font choices, double-click your chart, and on the Chart Customization dialog box, click Font, and choose your font size, face, and style.

Font Selection Considerations

The following suggestions will make your chart easier to read:

• Use the same font face for all chart elements.

• Apply only one font style to each chart element. For example, use only bold or italic for the title, rather than both.

• Limit use of the italic style.

Changing the Color Scheme of an Enhanced Chart

You can view your chart in color, monochrome, or in monochrome + symbols. If performance is an issue, you will probably want to view your chart in monochrome because it is less taxing on the system.

If you choose to view your chart in color, you can customize every color aspect of the chart's appearance. The following illustration highlights each of the items you can customize, which include titles, legends, and graphs.

Using Pre-Set Styles

For easy color-customization of your chart, you can use a pre-set style. Pre-set styles provide comprehensive color themes for your chart. There are twelve themes available in light, medium, or dark color combinations. Additionally, you can easily add gradient shades to your chart. In the following example, Dark Inset was selected as the pre-set style. By applying a bitmap or gradient style to the Dark Inset, the chart on the right results.

Dark Inset Selected Bitmap / Gradient Styles and Dark Inset Selected

iFIX Enhanced Charts with Pre-Set Color Styles Applied

To customize your chart's colors, double-click your chart, and on the Chart Customization dialog box, click Color, and choose your viewing style, graph attributes and style.

Color Selection Considerations

We recommend keeping the following suggestions in mind when making your chart color selections:

• If performance is an issue, avoid using color. Instead, view your charts in monochrome.

• Avoid the use of too many bright colors. It can make your chart unpleasant to look at. Instead, use bright colors to highlight specific information, thus drawing attention where you want it.

Defining the Plotting Style for Enhanced Charts

Defining the plotting style for an enhanced chart includes choosing the type of line you want to use to plot your data, selecting the data point type, choosing the color for the line, labels and data points, and adding shadows to the data points, if desired. For line/multiline charts, you may also select the type of chart to use.

All plotting style choices can be selected on the Plotting Style tab of the Chart Customization dialog box.

Working in the Run-time Environment for Enhanced Charts

The following sections describe how to configure Enhanced Charts for specific attributes in the run-time environment:

• Defining Run-time Attributes for an Enhanced Chart

• Zooming in an Enhanced Chart

• Displaying Time Cursors in an Enhanced Chart

• Understanding Chart Time for Enhanced Charts

• Adjusting for Daylight Savings Time for Enhanced Charts

• Choosing Subsets for Line/Multiline Graphs

• Marking Data Points in an Enhanced Chart

Defining Run-time Attributes for an Enhanced Chart

You can assign certain attributes in the configuration environment to make the chart accessible when you switch to the run-time environment. You can specify these attributes by selecting the appropriate check boxes on the General tab page of the Chart Customization dialog box. The following table describes each attribute.

Selecting the check box...

Lets you...

Highlightable Highlight the object at run-time.

Selectable Select the object at run-time. Example: Zoom in on an area of the chart.

Modifiable Modify the object at run-time. Example: Modify chart properties using the Chart Configuration dialog box.

Zooming in an Enhanced Chart

When a chart is selectable, you can zoom to an area of the chart by placing the cursor within the chart area and clicking an area, or enclosing an area in a rectangle selector. When the cursor is in the chart area, it becomes a magnifying glass. You can zoom to the horizontal, vertical, or both axes in the chart to view specific data. To zoom out on the chart, press Z. Alternatively, you can use the right-click menu. Select Chart Options and then Undo Zoom.

To enable zooming for your chart, on the General tab of the Chart Customization dialog box, select the desired zooming capability.

Displaying Time Cursors in an Enhanced Chart

You can choose to display time cursors in the run-time environment. The time cursor appears as a crosshair, which moves as you move the mouse. The value of the time cursor is displayed in the legend.

For historical pens, the value at the point of the time cursor is displayed; for real-time pens, the current value is always displayed. To display the time cursor in the run-time environment, select Show Time Cursor on the General tab of the Chart Customization dialog box.

NOTE: The chart must be selectable to view the time cursor at run time.

Displaying Time Cursor Tool Tips in an Enhanced Chart

You can display tool tips in the run-time environment. When tool tips are enabled, placing the mouse pointer over a point in the chart causes the value of the point, along with the time and date stamp for that point, to display in a pop up box.

In the following figure, which depicts a line chart, the point, along with the time stamp appear in the turquoise pop up box.

In the following figure of an XY chart, the X and Y values for the point are displayed, as shown in the green pop up box.

Enhanced Chart with Tool Tips

To display the tool tips in run mode, select Show Time Cursor Tool Tips on the General tab of the Chart Customization dialog box.

Displaying Data Point Labels in an XY Chart

You can display the labels for all data points in an XY chart in the run-time environment.

The following figure displays an XY chart where the values, or labels, for all of the data points are displayed. It also illustrates a second way to view the values for a single data point, the tool tip. The tool tip, along with the time stamp, appears in the green pop up box. Enabling data point labels allows you to read all of the points' values at once. And, the values continue to display for as long as the chart is displayed in run mode. To check the value of a single point, you can use the tool tip. The value of the selected data point does not continue to display after you move the tool tip away from it.

XY Chart with Data Points Labels

To display the data points labels in run mode, select Include Data Labels in the Miscellaneous area on the Chart Style tab of the Chart Customization dialog box.

Data Source Limit Symbols

If your chart uses data source limit symbols to demarcate the axes limits, the Data Point Labels will use those too. In the following figure, the Tool Tips display the actual value; the Data Point Labels do not. Instead, the labels reflect the same substitution as the data source limits; the zeros and the data source limit symbol are implied. For more information on data source limit symbols, refer to Understanding Enhanced Chart Data Source Values Symbols.

Data Point Labels with Data Source Limits Symbol

Understanding Chart Time for Enhanced Charts

The relationship between the following fields must be considered when you use a fixed start time and date in a chart:

• Lock Time

• Time Zone (Proficy Historian only)

• Adjust for Daylight Savings Time (Proficy Historian only)

iFIX charts save time as Coordinated Universal Time (or UTC time). When you switch to the run-time environment, UTC time is read from the picture file containing the chart, and is then converted to local time before the chart fetches data from the historical file. Therefore, when you configure a chart, time is entered and displayed in local time. However, the time saved within the chart is in UTC time, which allows the data to be displayed independently of specific time zones. The following examples help explain the concept of using time zones and daylight saving.

Example 1: No Features Enabled

In this example, pictures are created and saved in Eastern Standard Time (EST). The Duration Before Now is set to 01:00:00, Days Before now is set to 0, and the current time is 10:00 a.m.. You get these results when you open the picture in the indicated time zone:

EST – displays data from 9:00 to 10:00 a.m.


Example 2: Lock Time Feature is Enabled

In this example, pictures are created and saved in EST. The Lock Time is selected, the Duration Before Now is set to 01:00:00, Days Before now is set to 0, and the current time is 10:00 a.m. You get these results when you open the picture in the indicated time zone:

EST – displays data from 9:00 to 10:00 a.m. local time.

Example 3: Using Server Time Zone (Proficy Historian only)

A picture configured to use the server time zone can be opened on any client machine in any time zone and will always show the same plot of data.

Example 4: Displaying Data from Multiple Time Zones (Proficy Historian only)

You have some points in the Proficy Historian archive that contain data from Mountain Standard Time (MST) and some from Pacific Standard Time (PST). You want to create a chart to display the events that occurred in each time zone at 10:00 a.m. Rather than being required to know the exact time zone location of each point and then choosing explicit time zones, you can select the tag time in the Time Zone field and set the Fixed Time at 10:00 a.m.

The UTC time feature of iFIX charts allows you to easily view and analyze a data plot, no matter where you display the data.

Adjusting for Daylight Savings Time for Enhanced Charts

If you are a Proficy Historian user, you have the option to adjust for daylight saving time. If you choose to adjust for daylight saving time, verify that Adjust for Daylight Savings Time is selected on the Time tab on the Data Sources tab when you add a DataSet to an iFIX Enhanced chart.

Before allowing automatic Daylight Saving Time to be used in a production environment, you should test your application under each of the following scenarios for proper behavior:

• While in Standard Time.

• While in Daylight Time.

• During the transition from Standard Time to Daylight Time.

• During the transition from Daylight Time to Standard Time.

Choosing Subsets for Line/Multiline Graphs

On an Enhanced Line/Multiline Chart, you can analyze a subset of the data presented in the graph. This is accomplished by selecting the number of data sources you want to analyze per graph from the Scrolling Subsets area on the Subsets tab of the Chart Customization dialog box. You may also select a data source, which will be present on all subset graphs by selecting it from the Baseline Subsets to Graph area.

After you have configured your subsets, you can view the results in run mode, where you can scroll through each of the subset graphs.

Marking Data Points in an Enhanced Chart

If you want a very precise depiction of the data, you can mark each of the data points. This way, in addition to viewing the data in a smoothed line, you can see each of the individual data points.

You can view the data points on an enhanced chart by selecting Mark Data Points in the Miscellaneous area on the Chart Style tab of the Chart Customization dialog box.

Performance Considerations and Limitations for Enhanced Charts

We recommend the following measures to keep your system's performance acceptable:

• Limit your charts to no more than 10 data sources per chart.

• Limit your charts to no more than 5 charts per picture.

• Avoid using the Snapshot feature if you are using an older CPU or lower end graphics card. In such a situation, the power necessary to create a full-screen Snapshot will cause other system processes to have very limited access to resources and may limit their performance.

• As a last resort, use the Monochrome Viewing Style.

• Do not use Classic Historian. Classic Historian is not supported for Enhanced Charts.

Exporting Data from an Enhanced Chart

Enhanced Charts allow you to export the data from a chart to a variety of formats. You can export the data to either picture or text/data format. If you choose to export the chart data to a picture format, such as EMF or JPG, you can choose the export size of the document, as well as the export location – the clipboard, a printer, or a file. If you choose to export the chart data to a text/data format, you can choose to export to the clipboard or a file.

When the data is exported, it can be used in a variety of ways and for multiple purposes, including further statistical analysis in Excel or for PowerPoint presentations.

If you export the chart data in a text/data format, the first row or column of the exported data represents the X-axis and the second row or column represents the Y-axis. Whether the axes are displayed in a row or column depends on the Export Style you select on the Export dialog box.

NOTE: Data exported from a Line/Multiline chart is interpolated. This is because the data is interpreted by assuming that the line between two values is a straight line. All points along that line are estimated. The data shown on the chart is processed and not the raw representation. However, if your Line/Multiline chart uses Trend for its historical mode, the chart's raw values are exported instead of the interpolated data.

Displaying SQL Data

iFIX can retrieve data that is stored in a relational database and display the data in a chart. The term SQL data encompasses any data that you want to display in a chart that is stored in a relational database.

For example, you may perform quality tests on your products or processes and record data from these tests. iFIX lets you view this data as charts, arrays, or single values. You can view numeric data from a relational database provided that the database supports ODBC queries.

iFIX gives you full control over how you display and manipulate SQL data by letting you create and edit VBA scripts. Refer to the Writing Scripts manual for detailed information on VBA scripts. For more information on using SQL data sources, refer to the Using SQL manual.

Using the Chart Group Wizard The Chart Group Wizard™ is designed for users who create or work with charts to monitor processes. The Chart Group Wizard offers you a flexible approach to charting data.

You can use the Chart Group Wizard to design and save multiple pen configurations in a chart group file. Operators can apply a saved chart group file to a chart and track its data, and then apply a different chart group file to the same chart and track different data. The Chart Group Wizard eliminates the need to clutter a picture with multiple chart objects and re-configure pen definitions to monitor different data.

For example, a manufacturing process may have these three process types:

• Temperature-sensitive

• Flow-dependent

• Fill-dependent

Using the Chart Group Wizard, you might create these chart group files to accommodate this manufacturing process: one that defines pens that track real-time and historical temperature-related data; one that tracks flow-related data; and one that tracks fill-related data. You need only one chart to display the data configured for each chart group file.

You apply a chart group file to the chart to display its data, and you then apply a different chart group file to monitor different data.

Displaying and Using the Chart Group Toolbar

Before using the Chart Group Wizard, you must import the Chart Group toolbar from the WorkSpace, if it is not already visible in the WorkSpace.

NOTE: Although hidden by default, you can access and use toolbars in Ribbon view. To access a toolbar in Ribbon view, on the Home tab, in the WorkSpace group, click Settings, and then click Toolbars.

To display the Chart Group toolbar:

1. In the WorkSpace system tree, double-click the Project Toolbar Files folder, and then the Toolbars folder.

2. Double-click the ChartGroupToolbar item to display the toolbar. The Chart Group toolbar should now display in the WorkSpace.

After importing the toolbar, the Chart Group Toolbar appears when you open a picture. The toolbar contains the three buttons shown in the following figure.

Before You Begin Working with the Chart Group Wizard

This section provides information you need to know before working with the Chart Group Wizard. In this section you'll learn about charts and pens and chart group files. You'll also be introduced to the demonstration picture available to you when you import the Chart Group Wizard.

Refer to the following topics for more details:

• Understanding Charts and Pens

• Understanding Chart Group Files

• Analyzing the Demonstration Picture

Understanding Charts and Pens

You must understand the concept and use of charts and pens to fully understand how to effectively use the Chart Group Wizard. A chart is an object that lets you display real-time and historical data. iFIX charts are multi-pen; they allow you to configure multiple pens in one chart to plot different data trends. Each pen is defined by its data source and can be uniquely configured to draw a trend line with its own color, line style, time range, marker style, and data limits.

A pen can plot three types of data:

• Real-time

• Historical

• T-data (data obtained from a trend block of a real-time data source)

The type of data you plot determines the pen type, which determines the appropriate properties for the pen. For example, the Days Before Now property is appropriate for an Historical pen, but is not appropriate for a real-time pen.

For more complete information on charts and pens, refer to the Using Charts to Analyze Process Trends chapter.

Understanding Chart Group Files

A chart group file is a collection of pens configured in the Chart Group Wizard. When you use a chart group file, you save your pen configurations as .CSV files in the C:\Program Files\Proficy\Proficy iFIX\HTR subdirectory. Each pen has its own data source and configurations, such as color, line style, and limits. You can create a chart group file independently of a chart. You can extract pen configurations from existing charts and create a chart group file from that configuration.

You can use chart group files in both configuration and run mode. In configuration mode, you can:

• Create, open, delete, and save chart group files.

• Apply a chart group file to a chart when a picture opens or when you click an object.

• Apply options that determine which functionality is available to you in run mode.

You can perform the same actions in run mode as in configuration mode. You can additionally perform these actions in run mode:

• Apply or associate a chart group file with a chart.

• Apply a chart group configuration to a chart without associating a chart group file with the chart.

You can open chart group files in other applications, such as Microsoft Excel™, to view and modify the file contents.

Analyzing the Demonstration Picture

When you import the Chart Group Wizard, the demonstration picture ChartGroupDemo.grf appears under the Pictures folder in the WorkSpace System Tree. This picture is provided to help you gain a better understanding of working with the Chart Group Wizard.

Before you use this picture, you must enable the Local Node Alias in the System Configuration setup.

To enable the Local Node Alias:

1. Ensure that you are logged in as an Administrator.

2. Open the System Control Utility (SCU).

3. On the Configure menu, click Local Startup. The Local Startup Definition dialog box appears.

4. Click the Local Node Alias check box.

5. Click OK.

Once you've enabled the Local Node alias, you can open the demo picture by double-clicking the ChartGroupDemo, located in the Pictures system tree of the WorkSpace. The picture contains two charts, Chart1 and Chart2. These charts are provided in the demonstration picture to illustrate the versatility of using the Chart Group Wizard in run mode.

Use the following chart group files, located in the C:\Program Files\Proficy\Proficy iFIX\HTR directory, with Chart1 and Chart2:

ChartGroup1.csv – plots data from nine data sources.

ChartGroup2.csv – plots data from four data sources.

ChartGroup3.csv – plots data from two data sources.

Each of these chart group files contains different pen configurations and varying high limits and fetch pen limits. The data sources for each are displayed when you apply a file to a chart.

Using the Demonstration Picture in Run Mode

In run mode, you can double-click Chart1 to invoke the Chart Group File dialog box, from which you can create a new chart group file or open and modify existing ones, such as ChartGroup1.csv.

Chart2 does not have the Chart Group Wizard applied to it, which prevents you from selecting a chart group file to apply to the chart. However, you can apply a chart group file to Chart2 by clicking one of the three command buttons. The Click event of each command button is configured to use an exposed Chart Group Wizard method (CGW_ApplyFileToChart) to apply a specific chart group file to Chart2. The command buttons use ChartGroup1.csv, ChartGroup2.csv, and ChartGroup3.csv, respectively.

Defining Pens in a Chart Group File

To define a pen, you should know how to use the Expression Builder, understand what data sources are, and know how to define them. Refer to the following sections for more details:

• Adding, Modifying, Deleting, and Re-Ordering Pens

• Setting Pen Styles

• Setting Pen Properties

• Historical Mode Options

• Applying Changed Pen Configurations to a Chart

For additional information, refer to the Creating Pictures and Understanding iFIX manuals.

Adding, Modifying, Deleting, and Re-Ordering Pens

The Pen List area displays the pen data sources. Use the four buttons on the Pen toolbar to add, delete, and re-order the pen sequence in the list box. The Pen toolbar is shown in the following figure.

Pen Toolbar

Adding and Editing Pens

To add a pen, you can perform any one of these actions:

• Click the Add button.

• Double-click the default pen syntax definition, Fix32.Node.Tag.Field.

• Double-click directly below the last pen in the Pen list.

To clear all pens from the Pen List before adding new pens, click New. If you have already modified the existing pens, the Chart Group Wizard prompts you to save your changes before it clears the Pen List. Double-click an existing pen to modify its data source.

The Expression Builder appears each time you add a pen. Click the down arrow to display a drop-down list of the ten most-recently defined pens in your iFIX system. Click the Browse button to select a new data source for the pen.

Deleting Pens

You can delete a pen, as long as at least one pen remains defined to a chart group file. If the file contains only one pen, re-configure the pen or delete the file if the you no longer need the information.

To delete a pen from a Pen List, select the pen and then click the Delete button, located above the Pen List.

The Chart Group Wizard does not prompt you to verify that you want to delete the pen; it removes the pen from the Pen List. If you decide not to delete the pen, close the Chart Group Configuration dialog box without saving your changes.

Reordering Pens

The order of the pens in the Pen List determines the order of pens listed in the chart key and the default labels that appear on the X-axis and Y-axis of the chart in run mode.

After adding two or more pens to a chart group file, you may want to change the order of the pens in the Pen List. To change the order of a pen in the Pen List, select the pen and then click the Up arrow to move it up in the list or the Down arrow to move it down.

Setting Pen Styles

You can set individual line styles to distinguish each pen in your chart. The Pen Style area in the Configure Chart Group dialog box contains these properties:

Line Style - determines what type of line to display, such as solid, dashed, or dotted. To choose a line style, select one from the drop-down list box.

Line Color - sets a color for the line. To select a color, click the Line Color field and select a color from the Select Color dialog box. These colors also apply to the X- and Y-axis and legends in the chart.

Marker Style - sets a shape or character that represents the pen marker in your chart. Markers are convenient for discerning shapes and characters if you print your charts on a non-color printer. To select a marker, choose one from the drop-down list box. If you choose the Character option, enter a character in the Marker Character field.

Line Width - sets the width of the pen's plot line. The default line width is 1.

Setting Pen Properties

Once you add pens to the chart group file, you can set individual properties for each pen. For historical pens, you can also select an option to use common time settings for each pen.

Setting Time-Related Pen Properties

The Time area of the Chart Group Configuration dialog box sets time-related properties for the selected pen. These properties depend of the type of pen: Real-time or Historical.

The Duration pen property is the only property that you can set for Real-time pens. It also applies to historical pens and is used by the Historical Mode property. The Duration property sets the time duration for the chart. Enter a duration value in this format:

dd:hh:mm:ss

For historical pens, you can assign a time range to each pen or specify one global time period. Applying different time ranges to the pens lets you compare data from different time periods, which helps to plot ideal curves rather than actual curves.

The following table describes fields in the Time area that pertain to historical pens.

Historical Time Property Fields

Option Description

Apply Time to All Historical Pens

Applies a common time period to all historical pens. When you select this option, you receive a message indicating that you are about to overwrite existing time properties for your historical pens.


Option Description

Time Before Now

Specifies the number of days and hours before the current time to start the display. Select a value from the drop-down list or enter a value, in this format:

dd:hh:mm:ss

where the variables represent the number of days, hours, minutes, and seconds before the current time.

Fixed Start Time

Specifies a specific date and time on which to start the display. Enter a date and time, using this format:

mm/dd/yy hh:mm:ss AM |PM


Option Description

Duration The duration for the display, which determines how much data to display on the X axis. The minimum duration for a display is 1 second; the maximum is 99 days, 23 hours, 59 minutes, and 59 seconds.

Using Proficy Historian, the minimum duration for a display is 1 second; the maximum is 365 days, 23 hours, 59 minutes, and 59 seconds.

Enter a value in the following format:

dd:hh.mm.ss


Option Description

Interval A time interval between the samples taken from the Historical Collect data file. The interval cannot be greater than half the Duration value.

When the Span Interval is 0, the time interval between data samplings is determined automatically based on the span duration divided by the maximum number of display points.

Enter a value in the following format:

dd.hh.mm.ss


Option Description

Display milliseconds

Allows you to enter milliseconds into the interval field. If you select this option, enter a value for the interval in the following format:

dd.hh.mm.ss.ms

Time Zone: The time zone to associate with the start time. You can select an explicit time zone, the client time zone, the server time zone, or the tag time zone. The default time zone is that of the client machine. This field is only available when Proficy Historian is being used.


Option Description

Adjust for Daylight Saving Time

Adjusts the time when the zone you selected is experiencing daylight saving if you selected the Automatically adjust clock for daylight saving changes check box in the Control Panel. This field is only available when Proficy Historian is being used.

Setting Properties Related to Data Limits

Data limit properties control how data is presented by the selected pen. The default, Fetch Limits, automatically retrieves the low and high limits assigned to the data source. These assigned limits appear as dim values in the High limit and Low limit boxes.

To override the default values, clear the Fetch Limits check box and enter high and low limit values in the respective fields.

Historical Mode Options

You use the Historical Mode options in conjunction with pens that display historical data. The display mode determines how iFIX selects data from an historical data source, displays it in the chart, and indicates what each displayed value represents.

The Historical Mode options are directly related to the Duration time property, as the duration determines the range of data used to calculate the data point plotted for the interval. The options in the Historical Mode drop-down list box are described in the following table.

Historical Mode Types

Option Description

Sample The pen plots the last valid value, up to and including the start of the interval.

Avg The pen plots the average of all valid data found during the interval, starting at the beginning of the interval, 12:00:00.

High The pen plots the highest value found during the interval, starting at the beginning of the interval, 12:00:00.

Low The pen plots the lowest value found during the interval, starting at the beginning of the interval, 12:00:00.

Applying Changed Pen Configurations to a Chart

You can use the Apply button in the Chart Group Configuration dialog box to apply the pen configurations displayed in the Pen List to the chart without associating a chart group file with the chart. The Apply button applies the pens to the chart and closes both the Chart Group Configuration dialog box and the Chart Group File dialog box, returning you directly to the WorkSpace in run mode.

To apply the current pen configurations without associating a chart group file with the chart, modify the current Pen List and click Apply.

A chart without an associated chart group file displays <no file> in the Chart Group File field of the Chart Group Configuration dialog box.

If you create a new chart group file and want to save the file as well as apply it to the selected chart, click the Save As button.

How the Chart Group Wizard Works in Configuration Mode

The Chart Group Wizard provides many charting options in configuration mode. You can use any of these three methods to create a chart group file:

• From inception.

• From an existing chart group configuration.

• From an existing chart group file.

You can use the Chart Group Wizard in configuration mode to:

• Apply the Chart Group Wizard to one or more charts in a picture to enable the operator to access the Wizard in run mode.

• Create, modify, save, and delete chart group files.

• Apply a default chart group file to a chart when a picture opens or on an object's Click event.

When you create a chart group file from an existing chart configuration, you can retain pen data sources that you know work for your process environment. The ability to extract existing pen configurations adds convenience when you implement the Chart Group Wizard in your iFIX configuration.

Applying the Chart Group Wizard to a Chart

You must use configuration mode to apply the Chart Group Wizard to one or more charts in your picture, or to remove it from one or more charts. If your picture contains multiple charts, you may want to apply the Chart Group Wizard to all or a subset of the charts in one operation.

When you apply the Chart Group Wizard to a chart, you can then invoke it when you double-click the chart in run mode. This enables you to use the Chart Group Wizard in run mode to:

• Select a chart group file to apply to the chart.

• Select a chart group file to apply pen configurations to the chart.

• Create and manage these chart group files.

NOTE: If you apply the Chart Group Wizard to a chart, be sure to clear the Modifiable check box on the General tab of the Chart Configuration dialog box. By clearing this check box, the double-click event invokes the Chart Group Wizard in run mode, rather than the Chart Configuration dialog box.

NOTE: If you do not select a chart, the Chart Group Wizard displays a message reminding you to first select a chart before trying to apply or remove the Chart Group Wizard.

Considering When to Apply the Chart Group Wizard

You may want to consider which charts should have Chart Group Wizard functionality in run mode before applying the Chart Group Wizard to all the charts in your picture. You may not know the best pens to apply to a chart. The operator, who typically monitors the system, may have a better idea of what to track to find problems. You may consider giving the operator the opportunity to choose a chart group file to apply to a chart and the ability to modify and save chart group file configurations. If you want tighter control on what is monitored in your system, you can implement security options, which are described in Preventing Run-time Changes to Chart Group Files.

You may also want to add configuration properties to the chart that are only available through standard configuration, in the Chart Configuration dialog box. For more information, see Applying Chart Properties.

Determining if Chart Group Wizard is Applied to a Chart

Use either of these methods in configuration mode to determine if the Chart Group Wizard is applied to a chart:

• Expand the system tree for the chart object. If the Chart Group Wizard is applied to the chart, the variable string object, `FileName' exists.

• Edit the script for the chart object by selecting the chart object. Right-click and select Edit Script. A chart that has the Chart Group Wizard applied contains the following script for the Double-Click event: CGW_OpenChartGroupForm

To determine which charts have the Chart Group Wizard applied, double-click the chart in run mode. The charts that have the Wizard applied display in the Chart Group File dialog box.

Configuring and Applying Chart Group Files

The steps that follow explain how to configure and apply chart group files.

To configure and apply chart group files:

1. In Classic view, in the iFIX WorkSpace, click the Configure Chart Group Files button on the Chart Group toolbar.

-Or-

In Ribbon view, on the Tools tab, in the Charts group, click Chart Groups, and then click Configure Chart Group Wizard.

2. Define a pen configuration that you want to save and apply to charts.

3. In the Chart Group Configuration dialog box, click Save.

4. Enter a file name.

5. Click OK.

6. Configure as many chart group files as needed.

7. Insert a chart in a picture. Ensure that the chart is selected.

Applying a Chart Group File to a Chart

When you switch from configuration to run mode, a chart that has the Chart Group Wizard applied appears blank until you associate a chart group file with the chart. In some cases, the application developer may have already defined a default chart group file for the chart; in this case, the chart may automatically begin plotting data when you open the picture or when you click an object.

Use the following steps to apply the Chart Group Wizard to a chart in configuration mode, and then to apply a chart group file to the chart in run mode.

To apply a chart group file:

1. Select a chart to apply the Chart Group Wizard to.

2. In Classic view, in the iFIX WorkSpace, click the Apply Chart Group Wizard to Chart button on the Chart Group toolbar.

-Or-

In Ribbon view, on the Tools tab, in the Charts group, click Chart Groups, and then click Apply Chart Group Wizard to Chart.

3. Click the Apply Chart Group Wizard to Chart option.

4. Click OK. This applies the Chart Group Wizard to the selected chart.

5. Switch to run mode and double-click the chart. The Chart Group File dialog box appears.

6. Select one of the chart group files you created.

7. In the Chart Group File dialog box, click Apply. This applies the chart group file to the chart.

Creating and Managing Chart Group Files

You can create and manage chart group files from the Chart Group File dialog box, as indicated in the following table.

Creating And Managing Chart Group File

Click... To...

New Create a new chart group file.

Add Folder

Add a folder to the C:\Program Files\Proficy\Proficy iFIX\HTR directory.

Delete File

Delete a selected chart group file.

Edit File Modify an existing chart group file.

Creating And Managing Chart Group File

Click... To...

Save Save a new or modified chart group file.

Save and Apply

Save a new or modified chart group file and apply it to the chart.

The New and Edit File button invokes the Chart Group Configuration dialog box, where you can add, modify, and delete pens. You cannot modify and save existing chart group files if the application developer set options in configuration mode that protect the files from any changes. Refer to Defining Pens in a Chart Group File for more information about defining pens.

Applying a Default Chart Group File to a Chart

A chart group file is typically not associated with a chart until the operator applies the chart group file in run mode. When you switch from configuration to run mode, a chart that has the Chart Group Wizard applied appears blank until you associate a chart group file with the chart. If the application developer has already defined a default chart group file for the chart, it may automatically begin plotting data when you open the picture or when you click an object.

However, you may want to assign a default chart group file to a chart in configuration mode, which is applied automatically in run mode. Assigning a chart group file ensures more control at run time. For example, as an application developer, you can remove Chart Group Wizard functionality from a chart and then assign a specific chart group file to the chart in run mode.

You can automatically apply a chart group file to a chart when:

• A picture opens.

• The operator clicks an object, including the chart itself

You can also let the operator make the chart and chart group selections at run time.

Displaying the Name of a Chart Group File

You may want to display the name of the chart group file associated with a chart to allow operators to determine which chart group file they applied.

To display the name of a chart group file without scripting:

1. Insert a chart in your picture and apply the Chart Group Wizard to it.

2. Insert a data link in your picture.

3. Enter the FileName variable object's InitialValue property as the data link's data source. For example, MyPicture.Chart1.FileName1.InitialValue.

4. Switch to run mode and apply a chart group file to the chart with the Chart Group Wizard. The name of the chart group file you applied appears in the data link.

To display the name of a chart group file with scripting:

1. Insert a chart in your picture and apply the Chart Group Wizard to it.

2. Insert a text object in your picture.

3. Position the cursor on the text object and click the right mouse.

4. Select Edit Script to register the text object in VBA.

5. Enter the following script below the CGW_OpenChartGroupForm on the chart's double click event:

Text.Caption = FileNameX.InitialValue

where Text is the name of your text object and X is the number of the FileName variable.

Preventing Run-time Changes to Chart Group Files

The Chart Group Wizard allows operators to configure chart group files in run time. However, for security reasons or to retain tighter control over process monitoring, you may want to limit which activities operators perform against chart group files in run mode.

Specifically, you can allow operators to apply a chart group file to a chart in run mode, but limit their ability to create a chart group file or modify and save existing chart group files.

Saving Chart Group Files

When you save a chart group file, you also save one or more pen configurations that you can apply in run mode to track different aspects of your process environment. The system file is saved in the C:\Program Files\Proficy\Proficy iFIX\HTR directory as a .CSV file. You have the option of saving the file in this directory or in a folder that you add to the directory. Use folders to organize your chart group files logically.

The Chart Group Wizard also lets you create and save multiple chart group files in one session of the Chart Group Configuration dialog box. When you click OK in the Chart Group File dialog box, the Chart Group Configuration dialog box reappears. You can continue to create, edit, and save chart group files before closing the dialog box.

How the Chart Group Wizard Works in Run Mode

The Chart Group Wizard gives operators the flexibility to apply different chart group files and pen configurations to charts. Depending on settings applied to a chart group file in configuration mode, operators may also create, modify and delete chart group files.

To apply chart group files to a chart in run mode, the chart must have the Chart Group Wizard applied to it in configure mode. Refer to Applying the Chart Group Wizard to a Chart to review how to create charts and define pens.

Double-click a chart with the Chart Group Wizard applied to it to access the Chart Group Wizard. The Chart Group File dialog box appears. You can select a chart group file to apply to a chart, and you can apply the pen configurations without actually associating the chart with a chart group file.

Depending on how the applications developer configured the Chart Group Wizard, you can also create, modify, save, and delete chart group files. These capabilities allow you to target and select only the data you must monitor with the freedom to apply and save different pen configurations.

Using Scripting with the Chart Group Wizard

This section shows how you can use one exposed method to apply a chart group file to a chart and how to use scripting with other exposed methods to perform various tasks, such as applying the Chart Group Wizard to a double-click event.

A list of properties used by the Chart Group Wizard and a series of examples of using the Chart Group Wizard are also provided.

Refer to the following topics for more details:

• Applying a Chart Group File Through Scripting

• Applying the Chart Group Wizard Through Scripting

• Properties Defined Through the Chart Group Wizard

Applying a Chart Group File Through Scripting

The Chart Group Wizard lets you apply a chart group file to a chart through the following exposed method:

CGW_ApplyFileToChart

For example, you might include push buttons in your picture, where the Click event for each button applies a different chart group file to a chart. The demo picture, ChartGroupDemo, provides an example of this.

You can also apply a chart group file to any event of an object. For example, you can use the CGW_ApplyFileToChart method in a script for a rectangle's Mouse Down event. The Mouse Down event can apply a chart group file to a chart that plots the fill percentage of the rectangle and causes an alarm to sound when the value exceeds defined limits.

The following example shows code from the ChartGroupDemo picture for the first push button. This script uses the CGW_ApplyFileToChart subroutine to apply the ChartGroup1.csv file to the Chart2 object.

'Procedure: CommandButton1_Click() 'Purpose: To initialize the variable strHTCPath to the FIX ' 'iFIX HTC Path, then Apply the Chart Group 'File "ChartGroup1.csv" to the Chart "Chart2" ' Private Sub CommandButton1_Click() Dim strMyChart As String Dim strHTCPath As String strHTCPath = System.FixPath(htc_path) strMyChart = strHTCPath & "\ChartGroup1.csv" CGW_ApplyFileToChart strMyChart, "Chart2" End Sub

Applying the Chart Group Wizard Through Scripting

The Chart Group Wizard provides an exposed method that lets you apply the Chart Group Wizard to a chart through scripting. The following code example applies the Chart Group Wizard to the Double-click event of Chart1:

Private Sub Chart1_DblClick() CGW_OpenChartGroupForm End Sub

The CGW_OpenChartGroupForm method opens the Chart Group File form. This method has an optional parameter for entering a chart name. If you want to apply a chart group file to a specific chart on an object's Click event, you can enter the following code on the object's Click event; in this example, the object is a command button:

Private Sub Commandbutton1_Click() CGW_OpenChartGroupForm "Chart1" End Sub

Properties Defined Through the Chart Group Wizard

The Chart Group Wizard reads pen data sources associated with existing charts and some pen properties, which it can save in a chart group file. The Chart Group Wizard saves only those properties defined through the Chart Group Wizard. These properties include pen styles, such as color and line style, data limits, and time-related properties, as listed in the following table.

Properties Defined Through The Chart Group Wizard

Time Properties

Data Properties

Pen Properties

DaysBeforeNow

Data source MarChar

Duration HiLimit MarkerStyle

EndTime LoLimit PenLineColor

FixedDate HistoricalSampleType

PenLineWidth

FixedTime FetchPenLimits

StartTime

TimeBeforeNow

You can configure properties for the chart that you cannot configure through the Chart Group Wizard. To configure these properties, double-click the chart to open the Chart Configuration dialog box. You can configure these chart properties:

• Properties on the General tab.

• Properties on the X-axis, Y-axis, Grid, and Legend tabs on the Chart tab.

• The Show Line, Constant Line, Show Gaps, and Maximum Display Points properties on the Pen tab of the Chart tab.

Refer to Applying the Chart Group Wizard Through Scripting for a sample script of toggling between the Chart Configuration dialog box and the dialog boxes invoked by the Chart Group Wizard.

Examples of Using the Chart Group Wizard

This section provides examples of how you can use the Chart Group Wizard to understand process trends in the iFIX environment. The examples show how you can:

• Apply the Chart Group Wizard to a chart to use in run mode.

• Modify a pen definition and save it in a chart group file.

• Modify a chart group file in run mode, and then apply and save the changes.

• Apply a chart group file to a chart on an object's Click event.

Each of these examples is based on the sample picture, ChartGroupDemo.grf, provided when you install iFIX.

Example 1: Applying the Chart Group Wizard to a Chart

The Chart Group Wizard is applied to Chart1 in the ChartGroupDemo.grf demo picture.

To apply the Chart Group Wizard:

1. Select Chart1 in configuration mode.

2. In Classic view, in the iFIX WorkSpace, click the Apply Chart Group Wizard to Chart button on the Chart Group toolbar.

-Or-


3. Select the Apply Chart Group Wizard option.

4. Click OK.

Refer to Applying the Chart Group Wizard to a Chart for more details.

Example 2: Modifying a Pen Definition

The ChartGroupDemo.grf demo picture uses three chart group files:

• ChartGroup1.csv

• ChartGroup2.csv

• ChartGroup3.csv

You can modify these files in either configuration or run mode. Click the Configure Chart Group Files button on the Chart Group toolbar (Classic view) or on the Tools tab, in the Chart Groups group, in the Chart Groups list, click Configure Chart Group Wizard (Ribbon view). The Chart Group Configuration dialog box appears, allowing you to create or modify chart group files.

To modify a chart group file in run mode, double-click Chart1, which has the Chart Group Wizard applied to it. The Chart Group File dialog box appears, allowing you to apply, create, or edit a file.

Modify chart group files and their pen configurations in the Chart Group Configuration dialog box, as shown in the following figure. In this example, the Marker Style for the second pen has been changed to Rectangle Marker. ChartGroup1.csv is the open file and the Marker Style for the second pen has been changed from a Rectangle to an Oval. Click Save to save your changes.

Select ChartGroup1.csv in the Chart Group File dialog box and click the Edit File button. The ChartGroup Configuration dialog box opens.

Modifying a Pen Definition

When you associate this chart group file with a chart in run mode, the marker style set here displays as a rectangle.

You can make many other changes in this dialog box, including adding and deleting pen definitions and saving the file under another name.

Example 3: Applying a Chart Group File in Run Mode

The Chart Group Wizard is applied to the ChartGroupDemo.grf demo picture. In run mode, Chart1appears empty until you apply a chart group file to it. To apply a chart group file to a chart in run mode, double-click the chart. The Chart Group File dialog box appears. Click Apply, and then select a chart group file to apply to the chart.

The following figure shows the results of Chart1when you apply a chart group file to it. When you click the first command button, the ChartGroup1.csv file is applied to it.

Example 4: Applying a Chart Group File on an Object's Click Event

The Chart Group Wizard is not applied to Chart2 in the ChartGroupDemo.grf demo picture. This is evident as the expanded System tree for the Chart2 object does not display the variable object FileName.

However, Command buttons, 1, 2, and 3 are configured to apply a chart group file to Chart2 based on their respective Click event. The Visual Basic script for each of these buttons uses the exposed Chart Group Wizard method, CGW_ApplyFileToCha to automatically apply a file to a chart. Refer to Applying a Chart Group File Through Scripting for more information on automatically applying a file to a chart.

Before the chart can display detail, you must open the Chart Group Configuration dialog box, set the Marker Style to Oval Marker for the second pen listed in the ChartGroup2.csv file, and then switch to run mode.

Using Scripts with the Chart Group Wizard

The following sections describe how to use scripts with the Chart Group Wizard:

• Applying the Chart Group Wizard Functionality through Scripting

• Applying a Chart Group File through Scripting

Applying Chart Group Wizard Functionality Through Scripting

To apply Chart Group Wizard functionality to a chart through scripting:

• Use the CGW_OpenChartGroupForm method, which you can access through script that lets you apply Chart Group Wizard functionality to a chart. The syntax for the method is: CGW_OpenChartGroupForm

Example

1. Create a chart named MyChart.

2. Add the following script to the chart's double-click event: Private Sub Chart1_DblClick()

CGW_OpenChartGroupForm

End Sub

Applying a Chart Group File Through Scripting

To apply a chart group file to a chart through scripting:

• Use the CGW_ApplyFileToChart method, which you can access through script that lets you apply a chart group file to a chart. The syntax for the method is:

CGW_ApplyFileToChart(strFileName As String, strChartName As String)

StrFileName Name of file to attach to the chart.

strChartName Name of the chart to attach the file to.

Example

1. Create a rectangle named MyRect.

2. Create a chart named MyChart.

3. Create a chart group file named chartgrouptest.csv.

4. Add the following script to the rectangle’s double click event: Private Sub MyRect_DblClick()

CGW_ApplyFileToChart "C:\Program Files\Proficy\Proficy iFIX\HTR\chartgroupTest.csv", "MyChart"

End Sub

5. Enter the following syntax if you don’t want to hard code the path: Dim path As String

path = System.FixPath(Htc_Path)

CGW_ApplyFileToChart path & "\chartgroupTest.csv", "MyChart"

Troubleshooting This chapter details potential error messages you may encounter while using Historical Trending, their meaning, and a suggested course of action. It also details some items you should consider when using Historical Trending with ODBC.

Refer to the following sections for more details:

• Historical Assign and Historical Collect Messages

• ODBC Considerations

Historical Assign and Historical Collect Messages

The following tables list messages generated in Historical Assign and Historical Collect, and their corresponding meaning.

Historical Assign Messages

Historical Assign Message

Action or Meaning

Can't add group. Disk may be full. Check disk.

Check disk space and delete unnecessary files.

Cannot save a group with no tags. Close dialog anyway?

A group that contains no tags cannot be saved.

Configuration file write error. Disk may be full.




Action or Meaning

Enter a nodename. To use ? support in the tagname field you must first enter a node name in the Node field.

Field must be floating point type.

Make sure your tagname has a F_ field.

Illegal characters in nodename.

Node name must start with a letter and be less than 9 alphanumeric characters.

Illegal limit value. Enter a limit value greater than or equal to 0.



Action or Meaning

Insufficient disk space to save new configuration.


Insufficient disk space to save new group.


Invalid autopurge time entered.

Valid autopurge range is from 2-200 days.

Invalid rate value. Valid collection rates are:

1, 2, 10, 20, 30 seconds

1, 2, 10, 20, 30 minutes



Action or Meaning

Invalid value entered for phase.

Phase values are in 2 second increments from 0-58 seconds.

Maximum number of groups has been reached.

Up to 255 collection groups can be defined in Historical Assign.

Nodename is not valid. Save anyway?

The node name entered is not valid. Establish a session with the node in the SCU.

Phase must be less than rate.

The Phase value must be less than the Rate value.



Action or Meaning

This Node:Tag.Field not found. Use anyway?

Verify that the entry is valid.

This tagname is already assigned to the group.

The tagname is already entered for this group. You cannot enter duplicate tagnames into a collection group.



Action or Meaning

This qualifier is not a digital point. Use anyway?

Verify the qualifier block that you entered. The qualifier is usually a Digital Input or Digital Output block.

If you are not using a Digital block, a value of 0 stops collection and a value other than 0 starts collection.

Historical Collect Messages

Historical Collect Message

Action or Meaning

An overrun has occurred.

An overrun indicates that values for some tagnames in the group are not collected at the specified data collection rate. Overruns can be prevented by phasing this rate.

Data file write failure. Disk may be full. Unable to read data file.

Run HTC_SCAN from the iFIX Base path.

Existing data file corrupted.


Existing data file read failure.




Action or Meaning

No groups defined for collection.

A collection group must be defined in Historical Assign before starting Historical Collect.

System time has been changed. HTC cannot continue.

The system date or time has been changed to a time that precedes data collection for the file. Stop Historical Collect, reset the time or date, and restart Historical Collect.



Action or Meaning

HTC warning qualifier not found. Use anyway?

The qualifier block you entered for the collection group in the Historical Assign program does not exist in the database.

Unable to open configuration file. Run HTA.

This message appears if the historical path was changed in the SCU. Run Historical Assign and modify a tag in each collection group so that the new configuration can be read.



Action or Meaning

Error initializing HTC. Some .DAT files may have been erased.

This message appears if a historical collection group was deleted out of the iFIX HTR path by a means other than HTA.

ODBC Considerations

The following sections describe some items you should consider when using Historical Trending with ODBC:

• Using ODBC Drivers to Query Historical Data

• ODBC Access to Historical and Real-time Databases

Using ODBC Drivers to Query Historical Data

When querying historical data using ODBC drivers, be aware of the following conditions:

• If you specify an open-ended criterion (for example: greater than with no less than), there is a default timespan of two hours.

• If you query for a time span that does not fall within the time span of the historical file, you will receive an empty record set. For example, if you were to query all records between 05:00 and 07:00 on a day that has no XXXXXX04.H04, you would receive an empty record set.

• If you do not specify an interval, the default time span will be one minute.

ODBC Access to Historical and Real-time Databases

Both the iFIX and real-time historical databases can be accessed through ODBC. To perform the ODBC connection and the SQL query, make sure the table to query in the SQL Query statement is the same as the node defined in the group of the Historical Assign configuration. Use the DSN name iFIX Historical Data.

The following example illustrates sample code used to connect to ODBC using ADO.

Private conADO As Connection Private rsADO As Recordset Private Sub QueryDatabase(strTag As String, strStartTime As String, strEndTime As String) Dim strQuery As String strQuery = "SELECT * FROM THISNODE " + _ "WHERE TAG = '" + strTag + "' " + _ "AND INTERVAL = '1.0' " + _ "AND (DATETIME

>={ts '" + strStartTime + "'} AND " + _ "DATETIME <={ts '" + strEndTime + "'})" If conADO Is Nothing Then Set conADO = New ADODB.Connection conADO.ConnectionString = "DSN=iFIX Historical _ Data;UID=sa;PWD=;" conADO.Open End If If rsADO Is Nothing Then Set rsADO = New ADODB.Recordset End If rsADO.Open strQuery, conADO, adOpenForwardOnly, _ adLockReadOnly, adCmdText End Sub
