1 Introduction

Note The Mark VIeS Safety control does not support status options. For a description of status operations, refer to theMarkVIe Controller Standard Block Library (GEI-100682), the Status Monitoring (STATUS_ MONITORING) block.

Blocks are software subroutines that are included in the tasks to be run in the controller. Within the ToolboxST* application,the connections are accomplished graphically using pins and wires to form a data flow diagram. The blocks run in the orderlisted in the task. The connections between the blocks are RAM memory elements through which data is passed. Theseelements are referred to as variables. Each variable has a defined data type and must be connected to pins of the same datatype. Some block pins accept multiple data types and others are capable of converting from one data type to another.

Each block entry in the library consists of the following:

• Block name and category• Block description• Block diagram• Pin definitions• Application notes (optional)

Each block has a full name and a simple name. The full name is descriptive and too long to display in a block diagram. Forthis reason, all blocks have a simple name. The simple name is displayed in the ToolboxST application.

Floating point (REAL and LREAL) values conform to IEEE® 754. The standard defines certain computational exceptions thatmay produce non-standard results, such as divide by zero. These non-standard values include infinities and Not a Numbers(NaNs), which, if used in subsequent calculations, produce additional non-standard results. The software has been designed toprevent the production and proliferation of such values. Function block descriptions may include additional details concerningfloating point exception handling where needed.

Block Libraries also contain rubber blocks, which are sized according to the number of pins used. Within the library, theblocks are grouped functionally to simplify the task of converting ideas into blocks. For example, the Controller Monitor(CTRLR_MON) block is a member of the System category.

Note Pin names are given modifiers that provide additional information about the pin.

A graphical representation of the software for each block is provided in the form of a block diagram that includes the simpleblock name and block configuration pins and variable pins, which transfer data in and out of the block. The pins are locatedon the block diagram according to their usage. All input pins (pins read by the block) and block configuration pins are listedon the left. All output pins (pins written by the block) and state pins (pins read and written by the block) are listed on theright. The pin name is listed beside each pin inside the block diagram border.

Pin Name Modifiers Description^ prefixed with a carat (^ONREQ) Pin is rising-edge sensitive

[ ] suffixed with square brackets (STATE[4]) Pin expects a variable that is an array of the size indicatedwithin the brackets


1.1 Block Data TypeThe pin data type identifier is listed beside the pin outside of the block diagram border. The basic data types used in the blocklibraries are BOOL, INT, UINT, REAL, LREAL, DINT and UDINT. Blocks with data types ANY_NUM and ANY must havethe Block Data Type set to match the intended data type of the block output.

Note The default value of Boolean inputs is False unless the input is a block Enable, in which case the default is True andthe default value of inputs with data types INT, UINT, DINT, UDINT, REAL and LREAL is 0, until otherwise specified.

The block content provides tables to define the input and output pins. Each entry includes the block name for the variable,basic data type, typical scaling units, and a description of the variable. Typical scaling units are supplied for reference only;specific applications may use other scaling units as appropriate.

Data Type Identifier Basic Data Type DescriptionA Any (ANY) Any data typeB Boolean (BOOL) 8-bit BooleanI Integer (INT) 16-bit (Short) Signed IntegerDI Double Integer (DINT) 32-bit (Long) Signed Integer

R Real (REAL) 32-bit Floating Point

Data Type Identifier Type Definition Modifier Description# m Build time constant

Note The Block Data Type is set in the block Property Editor.

1.2 Change Data Type of Variant BlockThere are few blocks that support more than one data type as an input and/or output.

➢➢ To change the block data type

1. Select the block for which to change the data type.

2. From the Block Properties window, expand the General section.

3. From the Property Editor, select the Block Data Type.

4. From the Block Data Type drop-down box, select a valid data type for the block.


From the Block Data Typedrop down list , select a valid data type for the block.

1.3 Legacy Category BlocksSome of the controller software blocks have been put into the Legacy Category (this is the category that is used by theToolboxST Block Diagram Editor). This category is different than the blocks that reside in the Legacy Block Library. Legacycategory blocks are supported but not recommended for use in any new controller applications (ControlST V05.02 or later).They are in the LEGACY category because no new development is to be done to add any new functionality to these blocks. Inmany cases, there is a newer block that is preferred for use as a replacement for these blocks, as listed in the following table.

Legacy Category Rationale

Legacy CategoryBlock

ReplacementBlock Reason

_COMMENT_BF _COMMENT_COMMENT is equivalent to the current functionality of _COMMENT_BF_COMMENT_BF used to provided a carriage-return/page-feed in the Mark VI and earlyversions of Mark VIe controllers

TIMER TIMER_V2 TIMER_V2 supports AT_TIME output to RESET input

BFILT ON_OFF_DELAY Allows the Mark VIeS controller to have similar functionality as the Mark VIe controller

COMPHYS COMPARE Allows the Mark VIeS controller to have similar functionality as the Mark VIe controller

Note LEGACY category blocks are hidden by default in the ToolboxST application. Refer to the ToolboxST User Guide forMark Controls Platform (GEH-6700) for steps to display these blocks if needed for legacy support.


2 Black Channel Receiver (BLACK_RX)Block Category: Communications

The Black Channel Receiver (BLACK_RX) blockis a rubber block that allows for the connection ofup to 32 input variables of heterogeneous datatypes with rubber pins. By default, the block isdisplayed with only one variable input but may beexpanded as necessary for the application. If morethan 32 variables are required, the user may addadditional BLACK_RX blocks to the application.

The BLACK_RX block validates the integrity of the Mark VIeS Safety controller data signed by a corresponding BlackChannel Transmitter (BLACK_TX) block running in the transmitting device. The user configures the running rate of theBLACK_RX block on the receiving device to greater than or equal to the rate of the incoming Black Channel EGD page fromthe referenced transmitting device. The BLACK_RX block receives the Connection ID (CONN_ID), Sequence number(SEQ), Signature (SIGNATURE and SIGNATURE2), and variable data consumed from the referenced EGD page as inputs.The block also receives an Expected Connection ID (CONN_ID_EXP) input value used to validate the transmitted CONN_IDvalue. The user configures a corresponding CONN_ID input on the BLACK_TX block and the CONN_ID_EXP constantinput on the matching BLACK_RX block.

InputsName Data Type DescriptionCONN_ID_EXP Constant UDINT Expected connection IDCONN_ID UDINT Connection IDSEQ UDINT Sequence number

STALE_CNT Constant UDINT

The Stale Count (STALE_CNT) input is a Constant pin used to configure the number times theblock can run without the SEQ input value changing. If the number of times the block ran withoutthe SEQ value incrementing exceeds the STALE_CNT value, LINK_OK is driven to False andthe STALE_CNT pin defaults to 1. The value zero may be applied to the STALE_CNT pin todisable driving LINK_OK False due to stale sequence number transmission completely. Thisprovides the flexibility to monitor for stale data externally in the application code if necessary.

SIGNATURE UDINT Signature

SIGNATURE2 UDINT Second Signature

VAR01 ANY Input variable 1↓ ANY ↓

VAR32 ANY Input variable 32

OutputName Data Type Description

LINK_OK BOOL

The output pin, LINK_OK, is a single Boolean value that denotes the integrity of the control datareceived from the Black Channel. If any of the inputs from the Black Channel are corrupt, theSignature calculation will not match the SIGNATURE and SIGNATURE2 input values from thetransmitter (BLACK_TX) and LINK_OK will be driven False.If the CONN_ID value from the Black Channel does not match the CONN_ID_EXP value, LINK_OK output will also be driven False.

The BLACK_RX block also checks for out-of-order reception of SEQ values. If the sequence number does not monotonicallyincrease, LINK_OK will be driven False until the sequence number resumes increasing from the point at which theout-of-order reception was encountered. The block takes sequence number roll-over into account during run time.


3 Black Channel Transmitter (BLACK_TX)Block Category: Communications

The Black Channel Transmitter (BLACK_TX) block is arubber block that allows for the connection of up to 32input variables of heterogeneous data types. By default,the block is displayed with only one variable input butmay be expanded as necessary for the application. If morethan 32 variables are required, the user may add additionalBLACK_TX blocks to the application.

The block receives a Connection ID (CONN_ID) input used to uniquely identify a Black Channel connection between aspecific BLACK_TX block in the transmitting device and a specific Black Channel Receiver (BLACK_RX) block configuredin the receiving device. The Sequence Number (SEQ) output of the block monotonically increases each time the block runs.The BLACK_TX block creates a Signature that the BLACK_RX block uses for a data integrity check. The Signature output(SIGNATURE and SIGNATURE2) is calculated using the values of the CONN_ID, Sequence number (SEQ), and input dataof the variables connected to the block and transmitted to the receiver (BLACK_RX).

Each of the variables connected to the BLACK_TX block must be placed on a dedicated Black Channel EGD dedicated pagethat is configured for production at a rate tuned for the application. All of these variables should not only exist on the sameEGD page but must also exist on the same EGD exchange to provide coherency on the receiving end of the Black Channel. Ifthe number of the variables required by the application exceeds the length of the EGD exchange, additional BLACK_TXblocks, EGD pages, and exchanges may be used to scale the application.

4 Black Channel ExampleThe black channel feature enables the transfer of safety control data between two separate Mark VIeS Safety controllerdevices over the UDH network, using a new EGD page and unicast configuration. A matching pair of transmitter and receiverblocks, BLACK_TX and BLACK_RX, are configured for the two Mark VIeS Safety control devices in the application. Theseblocks run a data integrity check on each side of the black channel. The following figure displays an overview of the blackchannel setup.

This example uses two simplex Mark VIeS safety controllers installed and set up on the same UDH network, as displayedfrom the ToolboxST System Editor.


HMI with ToolboxST application

MarkVIeS_1 Device MarkVIeS_2 Device

New EGD Page

VAR## pins must be connected to the same global variables , in the same order , in both black channel blocks .

EGD Referenced Device

Black Channel Example


Open both Mark VIeS Component Editors, and select the General tab, Network Adapter 0, Adapter Settings. Verify thatthe IP addresses are properly configured to be on the same network. The Black Channel uses UDH EGD Pages to send databetween each of the controllers. Routable EGD or controllers in the same subnet are the available options in the Mark VIeSsystem, however any network topology that allows UDH EGD communication between the controllers would be consideredvalid.


➢➢ To configure the Mark VIeS safety controllers for Black Channel communications

1. Verify that the controllers have been properly installed and configured for UDH network IP addresses.

2. From the first Mark VIeS Component Editor, EGD tab, right-click Produced Pages and select Add Page. Enter aname for this page (for example blackTx).

3. Set the Destination to be the IP address of the second Mark VIeS controller and set theMode to be Unicast.

4. From the Software tab of the first Mark VIeS device, create a Program and Task, then insert the Black_TX block.

5. From the Software tab Tree View, select the Variables for the Task. From the Data Grid, create global variables for allBlack_TX block pins.

a. Create up to 32 VAR## variables as needed for the data to be transmitted from the first controller to the secondcontroller.

Note Use another pair of transmitter and receiver blocks if more than 32 variables are needed.

b. Select data types as are needed for the data to be transmitted or as are required for the block pins.

c. Select the EGD Page for each of these variables to be the black channel page created in step 2.


d. Use this example to verify that the data types for the Black_TX pins match the data types of the created variables.

e. Notice that the Initial Value for the CONN_ID is 1 in this example (BlackConnectionID). This Connection ID must be a unique number to represent this particularBlack_TX block (important when using more than one Black_TX transmitter block). This ID is used by the Black_RX receiver block to identify which transmitter block itis receiving.

6. To connect the global variables to the block pins, from the Block Diagram Editor, double-click the Black_TX block andselect Browse Globals.

7. Select the appropriate global variable created from step 5.

8. From the second Mark VIeS Component Editor, EGD tab, select Referenced Devices and select the first Mark VIeScontroller (MarkVIeS_1) in this example.

Under Referenced Devices, select the new device (MarkVIeS_1 in this example), and verify that the available globalvariables display.

9. From the Software tab, create a Program and Task, then insert the Black_RX block.

10. From the Software tab Tree View, select the Variables for the Task. From the Data Grid, create a Boolean globalvariable for the Link_OK pin.

11. From the Block Diagram Editor, and the Black_RX block, double-click the CONN_ID_EXP pin. Set the ImmediateValue to be the same as the Black_TX CONN_ID value (in this example it is 1). This value is especially important whenusing more than one set of blocks (to identify which Black_TX data values should be received by this particular Black_RX block).

12. Double-click the Black_RX block, select Browse Globals.

13. Select the global variables created in the first Mark VIeS controller, and connect them to the appropriate pins.

a. From the Select a Variable dialog box, select the folder with the name of the first controller device, then select theappropriate variable.

b. Attach the VAR## data variables in exactly the same order as they appear in the Black_TX block.

14. Build and Download both controllers (this can be done simultaneously).

15. Click each controller’s Status tab and wait for the controller to be in the Controlling state.


➢➢ To test the communication

1. Unlock the first controller.

2. From the Black_TX block, double-click a value for one of the VAR## pins (tiny green value).

3. From the Set Value dialog, change the Next Value and click Send & Close.

4. From the second controller’s Black_RX, notice that the data value of the matching VAR## pin has changed to match thesent value from the first controller.

5. Disconnect the UDH cable from the transmitter end (Mark VIeS controller).

6. From the Black_RX block, notice that the LINK_OK pin connected variable changes to False.


5 Boolean Filter (BFILT)Block Category: Boolean Operations

Note This block is not recommended for use in any new controller applications (ControlST V05.02 or later). Refer to thesection Legacy Category Blocks.

The Boolean Filter (BFILT) block passes a rising True value on the IN pin to the OUT pin if IN remains True for PU_DEL (inmilliseconds) time. The block passes a falling False value on the IN pin to the OUT pin if IN remains False for DO_DEL (inmilliseconds).

6 Calculator (CALC)Block Category: MATH

The Calculator (CALC) block is an expandable block that performs mathematical operations,defined by the equation string, on up to 8 inputs, A, B, C, D, E, F, G, and H, and places theresult in the output variable, OUT. The data type of the inputs and output is implied by the blockdata type selected in the Block Properties panel in the ToolboxST application. Any modificationto the equation string EQUAT requires a re-download to the controller.

The following operators are supported within EQUAT:+ (add), - (subtract), * (multiply), / (divide), ^ (power), % (modulus), ABS() (absolute value), NEG() (negate), LOG()(logarithm, base 10), LN() (natural logarithm), EXP() (Exponential e^x), RECIP (1/x), RND() (round to nearest integer), SQR() (square root), COS() (cosine), SIN() (sine), TAN() (tangent), ACS() (arccosine), ASN() (arcsine), ATN() (arctangent).

The equation must be stated in terms of the operators and the A through H operands. The trigonometric functions expect angleoperands to be expressed in units of radians.

There is a limit of 64 elements (Operands and Operators) that may be specified in the equation string. For example, anequation to ADD two input variables A+B, has two Operands (A and B) and one Operator (+): a total of three elements.

When using the division operator (/), if the denominator = 0, the denominator will be replaced by 3.4e-38.

When using the modulus operator (%), if the divisor = 0, the divisor will be replaced by 3.4e-38.

When using the RECIP() function, if the input operand A = 0, it will be replaced by 3.4e-38.

When using the SQR() function, if the input is negative, the output will be the square root of the absolute value of the input.

When using the TAN() function, if the input operand A is equal to np + p/2 (where n is an integer), then OUT = 0.

When using the LOG() function, if the input operand A is less than or equal to zero, then the output value is set to 0.

When using the LN() function, if the input operand A is less than or equal to zero, then the output value is set to 0.

When using the power operator (^), if the input operand A = 0 and operand B is not an integer, the calculation is done with therounded value of operand B.

Note This is a variant block which supports any one the following block data types: INT, DINT, REAL, LREAL, UINT, andUDINT. The default data type is REAL. Refer to the section Change Data Type of Variant Block.

7 Capture Data (CAPTURE)Block Category: System

The Capture Data (CAPTURE) block collects multiple samples of 1 to 32 variables in a buffer that can be uploaded toToolboxST application or the Data Historian for display and analysis. Multiple clients may upload the same buffer. The blocksupports a variety of triggering and sampling options. Changes to the configuration can only be accomplished by a download.An optional, automatic re-enable feature allows the collector to re-arm for the next collection following a specified timeoutfrom the last upload.

Level (2) – If the current trigger condition is True, the trigger is True.

AUTOENAConstantBoolean

AutomaticEnable

If True, the block is automatically re-enabled for a new capture after the buffer is uploaded. Notethat if automatic enabling is selected, all manual enable inputs are ignored (default is False).

ATOUTConstantUDINT

AutomaticEnableTimeout

The number of seconds after the last upload before capturing is re-enabled (only applicable ifAUTOENA is True) (default is 60 seconds).

BUF_CTLConstantBuf_Ctl_T

BufferControl

Buffer Control – Controls how and when the data is collected (default is NORMAL).

NORMAL (1) – PRE_SAM samples are collected before a trigger event. POSTSAM samples arecollected after the trigger event. Samples are collected every FMULTscans. Capturing stops whenthe specified samples have been collected, an upload command is received, or when the ENA_CAP pin transitions to False if automatic re-enabling is not selected.

CIRCULAR (2) – Samples are collected indefinitely every FMULTscans. The buffer contains thenewest PRE_SAM + POSTSAM samples unless capturing is stopped prior to filling the buffer.Capturing stops when an upload command is received, or when the ENA_CAP pin transitions toFalse if automatic re-enabling is not selected.

ONLY (3) – The trigger condition is evaluated each scan. Samples are only collected when thetrigger event is valid. The buffer contains PRE_SAM + POSTSAM samples unless capturing isstopped prior to filling the buffer. Capturing stops when the specified samples have been collected,an upload command is received, or when the ENA_CAP pin transitions to False if automaticre-enabling is not selected.

ENA_CAP BOOLManualEnable

If True and the AUTOENA pin is False, enable the block for capture. This pin gives the applicationcode the ability to enable and disable data collection. This is an edge-triggered pin. Once a capturehas been stopped the pin must be toggled False and then True again to re-enable the next capture(default is False).

FMULTConstantUINT

SamplePeriodMultiplier

Allows data to be collected slower than the performance rate of the block (scan period) byspecifying a multiple of the scan period for samples to be taken (only applies to Normal andCircular buffer control) (default is 1).

If a zero value is given, then the block will treat it as one Frame multiple.

Capture Block Theory of Operation

The Capture block is a software function used to collect application variables in real-time for offline display and analysis. Thecore software is shared between the Capture block and Dynamic Data Recorders (DDRs). The main differences between themare:

• Capture blocks require an application code download to configure, while DDRs are configured by an independentdownload mechanism.

• Capture blocks are embedded in the application code and can be used to catch events that occur between application codeblocks. DDRs perform outside of the application code and can only sample data after all of the application code hasperformed in a particular frame.

• Capture blocks perform at the same priority as the other application code and so insure the highest data fidelity. DDRsperform at a lower priority than the application code and are not guaranteed to catch data transitioning at frame rate.

The Capture block collects data sets of variables, known as samples and stores them in a local buffer. The buffer may beuploaded to one or more client devices. Once uploaded the block may be re-armed to take another collection. Typically, forclients other than ToolboxST application the status pin must be mapped to EGD so that it can be monitored outside thecontroller. Once an upload is in progress, the buffer is locked to prevent it from being re-armed during the data transfer.Multiple clients may upload the buffer simultaneously. The block ignores the transitions of its ENA_CAP pin until all clientshave been serviced.

Data collection is managed by specifying a buffer control mode and a trigger event. There are three buffer control modes. ANORMAL collection is one where a specified number of samples are collected prior to a trigger event and a specified numberof samples are collected after the trigger event. Once the trigger event has been found to be satisfied it is no longer evaluated.A CIRCULAR collection is one where no trigger event is specified and samples are taken indefinitely until the collection ishalted by requesting an upload or disabling the block. An ONLY collection is one where samples are only collected if thespecified trigger event is True each opportunity the block has to collect a sample. This is useful when collecting data aroundan event that occurs sporadically.

A trigger event is completely specified by selecting a trigger condition, a trigger type, a trigger variable, and a trigger value.The trigger variable is an application variable that the block monitors. It is compared against a trigger value using therelational specifications of the trigger condition, and the sensitivity of the trigger type. Acceptable trigger conditions includeEQUALTO, NOT EQUALTO, GREATER THAN, GREATER THAN OR EQUALTO, LESS THAN, and LESS THAN OREQUALTO. Acceptable trigger types include LEVEL or EDGE. A level trigger is one that is satisfied at present, regardlessof past values. An edge trigger is one that is satisfied at present but was not satisfied at the previous evaluation.

Capture Block Configuration

The Capture block may be re-configured by either an offline or online download. Downloading causes the states of ALLCapture blocks in the controller to be re-initialized, invalidating any data that may be in the process of being collected.Therefore, if external blockware is used to sequence to collection of data, it must be sufficiently robust to recover from such are-initialization. This may be accomplished by examining the DONE and STATUS pins or through timeouts.

Capture Block Enabling Collections

Note Avariable needs to be connected to the Status pin to enable the automatic upload functionality of the CAPTURE blockin the WorkstationST* application.

A new collection may be enabled manually through blockware, or automatically, if so configured. If manual enabling isselected, the application code must toggle the ENA_CAP to False for at least one frame then back to True to re-enable acollection. Additionally, the block ignores all transitions of the ENA_CAP pin while the buffer is locked for uploading so thistoggling must occur when the buffer is unlocked. If automatic enabling is selected, the block is initially enabled and alltransitions of the ENA_CAP pin are ignored. The block will re-enable a capture after at least one upload occurs, and no newupload requests are received within ATOUT seconds following the completion of the last upload. Uploading a collection thatis not complete automatically changes the block status to complete. Another upload is not necessary to re-enable the nextcollection.


Capture Block Triggering Issues

The trigger event is evaluated differently for each of the buffer control modes. For the NORMAL and CIRCULAR modes thesample period multiplier pin, FMULT allows the block to collect samples at rates slower than the block performs, therebyextending its range. A sample is only collected every FMULT scans. Using the NORMAL mode, the trigger event is evaluatedevery scan regardless of the value of FMULT. When the event occurs, the sample is collected and post-trigger samples arecollected every FMULT scans away from the trigger sample. Note that because the trigger sample may not occur on anFMULT boundary, the time between the last pre-trigger sample and the trigger sample may not be the same when FMULT isnot equal to one.

Capture Block NORMAL

NORMAL mode is used to collect samples before and after a specified trigger event.

Once enabled, the block begins collecting pre-trigger samples, retaining the most recent PRE_SAM samples before a triggerevent occurs. Once the trigger occurs, the block collects POSTSAM more samples before changing the STATUS pin toComplete. The trigger sample is included in the post sample count. Typically the buffer will contain PRE_SAM + POSTSAMtotal samples. If the trigger occurs prior to collecting all of the pre-trigger samples, or the collection is halted prior tocapturing all of the post trigger samples this may not be the case.

Capture Block CIRCULAR

CIRCULAR mode is used to collect samples continuously until the buffer is manually stopped. Specifying a trigger event ismeaningless in this mode.

Once enabled, the block begins collecting samples, retaining the most recent PRE_SAM + POSTSAM total samples. It ispossible for the buffer to contain fewer samples if the collection is halted prematurely.

Capture Block ONLY

ONLY mode is used to collect samples only when the trigger event is True. The FMULT pin is ignored in this mode.

Once enabled, the block begins looking for trigger events every scan but only collects samples on the scans where the triggerevent is True. The block collects the first PRE_SAM + POSTSAM trigger samples before changing the STATUS pin toComplete. It is possible for the buffer to contain fewer samples if the collection is halted prematurely.

Capture Block Time Stamping

The TSTAMP pin specifies whether wall clock time (in UTC format) is collected with each sample, or whether it is collectedonly at the trigger event and all other sample times are extrapolated from the block performance period modified by FMULT.

It is recommended that TSTAMP always be left True, to insure that trends are displayed with the most accurate timestampinformation.


Capture Block Status

The state of each collection is expressed through the DONE and STATUS output pins. The DONE pin may be monitored byapplication code to drive manual reset algorithms. The STATUS pin provides more detailed state information and is usuallypublished on EGD for use by external clients. The definition of the states is affected by the specified buffer control mode andis provided in the following table.

Buffer Control Mode Affected StatesStatus BUF_CTL DescriptionDISABLED All Prior to being enabled for the first time (manual enable mode only)

CIRCULAR Collecting samples

ONLY Collecting a trigger sample

COMPLETE All No longer collecting, ready to be uploaded, ready to be re-enabled

FLASHWRITINGNORMAL Writing the pre-trigger and post-trigger samples to flash.CIRCULAR Does not occurONLY Does not occur

Capture Block Redundancy Issues

Like all application code blocks configured in a redundant controller system, the Capture block is replicated faithfully in eachcontroller. However, unlike other blocks, the Capture block maintains un-voted internal state information in each controller.This independence allows the block to trigger on and capture data that may be different in each controller (for example,anti-voted data). Likewise the communication channel established between the block and an external client (for example,ToolboxST application) for an upload is not replicated to any redundant controllers. The STATUS and DONE pins are notvoted and as a result may not always track between controllers. This is normal if a capture is terminated early by an uploadrequest or anti-voted data is used in the trigger specification. Application writers who want to monitor these pins throughblockware should be aware of this discrepancy.

Capture Block Memory Use

Capture blocks consume RAM memory from the system memory pool to create the capture buffers. The allocation of memoryin the controller is a compromise that must be made considering the amount of real RAM available, the amount required forapplication code, the amount needed for data collection (for example, Capture blocks and DDRs), and a free pool necessaryfor support services, such as ToolboxST application and HMI connections.

The amount of memory required for a particular CAPTURE block may be calculated as the number of samples times the sumof the size of each collected variable. If time-stamping is enabled add 8 bytes times the number of samples. For example, if aCAPTURE block is configured to collect 1000 total samples where each sample contains two REAL, three INT, and fiveBOOL data types, and time-stamping is enabled, the amount of memory required for the captured data is:1000 x ((2 x 4) + (3 x 2) + (5 x 1) + 8) = 27,000 bytes

15 Controller Monitor (CTRLR_MON)Block Category: System

Note Only one instance of this block is allowed per controller.

The Controller Monitor (CTRLR_MON) block is used for various purposes. The Block has a POWER_UP output thattransitions to True 5 sec after the controller is in control mode. SIG_FORCED turns on if there are any forced variables in thecontroller, SIG_FORCED is set to False for 2 s every time the number of forced variables are increased. SIG_FORCED_NUM indicates the number of forced variables in the controller.

The block detects the current controller configuration (Simplex, Dual, or TMR). According to this configuration overtemperature alarms OVERTEMP_R, OVERTEMP_S, OVERTEMP_T (not applicable for all platforms, refer to the table,Platforms) and controller online variables ONLINE_R, ONLINE_S, and ONLINE_T are generated for R, S and Trespectively.

The input ONLINE_FL_TMR is used to delay the controller online variables change from True to False in the event thecontroller heartbeat stops.

Note CTRLR_MON creates global variables that can be used throughout the controller application software.

The outputs, HW_ALARM_R, HW_ALARM_S, HW_ALARM_T, become True any time a hardware failure diagnostic isgenerated for R, S and T controllers, respectively. The outputs, FAN1_FAIL_R, FAN1_FAIL_S and FAN1_FAIL_T, becomeTrue any time a FAN 1 failure is detected for R, S and T controllers, respectively (not applicable for all platforms; refer to thetable Platforms). The outputs, FAN2_FAIL_R, FAN2_FAIL_S and FAN2_FAIL_T, become True any time a FAN 2 failure isdetected for R, S and T controllers, respectively (applicable to UCSB only). Fans 1 and 2 are available only in the UCSB andthe corresponding failure outputs will be False for other platforms.

Note In the Virtual Controller, the OVERTEMP_R, OVERTEMP_S and OVERTEMP_T are all False because there is notemperature measurement functionality. ONLINE_S and ONLINE_T are always False irrespective of the controllerconfiguration (Simplex, Dual or TMR).

16 Counter (COUNTER)Block Category: Timers and Counters

The Counter (COUNTER) block accumulates rising edges of the INC pin into CUR_CNTwhile the RUN is True and CUR_CNT is less than MAX_CNT. When CUR_CNT is equal to MAX_CNT, AT_CNT transitions to True. If RUN is False thencounting is suspended, but CUR_CNT holds its value. If RESET is True then CUR_CNT is set to zero and counting issuspended. If MAX_CNT is less than one, each rising edge of INC sets AT_CNT True and increments CUR_CNT.

17 Device Heartbeat (DEVICE_HB)Block Category: System

The Device Heartbeat (DEVICE_HB) block outputs an incrementing value to drive the heartbeat signal on a protection I/Omodule, such as PPRO. This block follows the internal frame counter, which is synchronized in the three controllers of aTMR system.

The DEVICE_HB block provides a voted variable representation of the controller scheduler frame number (anotherfree-running counter). It is normally used to drive the heartbeat input into the protection I/O packs. Because the variable is thesame in all controllers in a redundant set. It does not cause a potential voter disagreement diagnostic in the packs (couldhappen with ControllerStateHeartbeat_R/S/T). The protection I/O pack trips the unit after five frames if no updates aredetected. After the unit trips, it must detect 60 frames of incrementing heartbeat before it allows the unit to go back online.

Note The OUT value freezes if the associated task/user block stops running.

18 Dual Select Version 2 (DUALSEL_S2)Block Category: Analog Operations

The Dual Select Version 2 (DUALSEL_S2) block transfers the average, minimum, or maximum of two analog signals tooutput ({Device}). The user has the option to disable one transmitter. If one transmitter is disabled, the output will be the valueof the remaining transmitter.

This block is similar to the Mark VIe DUALSEL_V2 block but functionality differs in the following ways:

• The DUALSEL_S2 block does not support the status option.• The Auto Enable (AU_EN_P) feature is not supported.• Control commands for disabling and enabling transmitters are supported in the DUALSEL_S2 bock; however, the

push-button reset functionality must be implemented in another device. For further details, refer to the description ofcontrol word (CTL_EXT) in the section Control Word.

Block Configuration

Disabling Transmitters

When the quality status of transmitter A (IN_ABQ) is BAD (False), ABQ and AD become True and transmitter A isautomatically disabled. Once the quality status of transmitter A becomes GOOD (True), ABQ becomes False. If the qualitystatus of transmitter A becomes GOOD (True) and the value of input A is within the deviation limits set by the user, ADbecomes False and A is automatically enabled. This concept also applies to input B.

A transmitter can be manually disabled using the CTL_EXT input. If input A and B are both enabled and have a GOODquality status and A is manually disabled, then the corresponding output, AD, becomes True to indicate that input A isdisabled. If input A is enabled and B is disabled, then BD is True.

Output Bad Quality Indication (OBQ)

When two transmitters are disabled and/or in a BAD quality state, OBQ becomes True, the default value, DF, is automaticallytransferred to output, and MODE is set to DEFAULT. OBQ becomes False when the quality status of either input becomesGOOD. The GOOD quality input will be enabled and transferred to the output.

Control Word

Control word (CTL_EXT) is used by the HMI operator for manual control. The manual commands from the HMI allow eachinput to be enabled or disabled. A manually disabled transmitter can be manually enabled, regardless of its deviation status.The command enumerations are defined in the following table.

CTL_EXT Enumerations

Enumeration CommandNO_CMD No CommandEN_A_CMD Enable Input A CommandDIS_A_CMD Disable Input A CommandEN_B_CMD Enable Input B CommandDIS_B_CMD Disable Input B Command

Note Operation of the CTL_EXT pin in the Mark VIeS control differs from that in other Mark VIe control products. In theMark VIeS control, the variable attached to the CTL_EXT pin must be from a consumed EGD page. The EGD producerdevice driving the variable must implement the necessary push-button reset logic.


Commands are only accepted by the block if a transition from NO_CMD to a command value is detected while the CTL_EXT input is healthy. After a command is accepted by the block, the CTL_EXT pin is ignored for a period of two secondsafter which a valid transition from NO_CMD must be detected to accept another command. An example configuration is asfollows:

Example Configuration

An HMI faceplate is created to display data from the DUALSEL_S2 block from a Mark VIeS control. EGD signals areconsumed by the HMI from the Mark VIeS control and are used to drive the faceplate. The control word from the MarkVIeS control is used for feedback. Control commands are sent to an EGD signal driven from a Mark VIe device. Forexample, after adding the DUALSEL_S2 block to the Mark VIeS control system and attaching the EGD signals to thefaceplate, the following configuration is required:

In a Mark VIe device:• Create a control word variable.• Add the control word variable to a produced EGD page.• Add push-button reset logic in the blockware to reset the control word value to NO_CMD (0). The control word should

be reset after one second of it being non-zero.

In the HMI:• Attach the control word variable from the Mark VIe control to the control word logic in the appropriate DUALSEL_S2

faceplate.

In the Mark VIeS device:• Attach the control word variable from the Mark VIe control to the CTL_EXT pin of the appropriate DUALSEL_S2

block.

Block Function Enumerations

Dual Select (DS) mode defines the block function mode. The function mode enumerations are defined in the following table.

DS Mode EnumerationsEnumeration FunctionAVG Average of A and BMIN Minimum of A and BMAX Maximum of A and B

Operating mode (MODE) is a block-operating mode that depends on DS and the quality status of the inputs. The operatingmode enumerations are defined in the following table.

MODE EnumerationsEnumeration Operating ModeAVG Average of A and BMIN_A-B Minimum of A and BMAX_A-B Maximum of A and BA Input AB Input BDEFAULT Input DF


Examples

• AVG,MIN_A-B, orMAX_A-B is the operating mode when both transmitters are not BAD quality and are enabled.• A mode is selected when transmitter B is manually disabled or determined to be BAD quality.• B mode is selected when transmitter A is manually disabled or determined to be BAD quality.• DEFAULT is the operating mode selected automatically when both transmitters are determined to be bad quality and/or

disabled.

Deviation Alarms

A and B values are compared to determine if the absolute value of their difference is greater than or equal to the deviationlimit, DL. If so, the deviation high alarm, ODH, becomes True, delayed by the deviation time delay, DT. The deviation alarmwill not become False until the absolute difference between A and B is less than the value of DL minus DLDB (deviationlimit dead band)or either input is disabled.

Note The deviation high output, ODH, becomes True when at least one transmitter is in deviation. Also, if a transmitterinput is disabled, the deviation alarm for that transmitter is disabled.

In general, the deviation alarm only sets Boolean outputs and has no influence on the functionality of the block (that is, thetransmitter in deviation with the output is not automatically disabled, and the block mode does not change).

Note Refer to the section Alarm and Event Configuration for more information.

Rate of Change Restriction

The rate of change of OUT is only restricted by the value of RATE when the block operating mode changes.

RATE is in engineering units per second. For example, if RATE = 1, A = 10 (enabled), and B = 25 (disabled), so MODE = A,and the mode of the block is changed by enabling input B and disabling input A. Now, MODE = B and output will increasefrom 10 to 25 engineering units in 15 seconds. At this point, output equals B, the block operating mode transition from A to Bis complete and the rate of change restriction on output is removed until the block operating mode changes, again.

ToolboxST Configuration

Inserting this block into the application program will generate the window displayed in the following figure. This prompts theuser to Enter Device Description, Enter Device Name, and Enter Format Specification in the Values column.

Changing Default Attributes


When the user clicks OK, the block will automatically set the appropriate attributes for each variable (for example, Type andFormat Specification). Any variables that need to be on EGD will be automatically placed on the $Default EGD page.

Note Each Device Name used in a controller must be unique.

The block and pin connections are configured automatically. The object will display in the ToolboxST application.

DUALSEL_S2 Block

Pin names are in the form Device Value.Pin Name, where Device Value has the attribute value 00DUALSEL_S21000 and pinName is the block input/output pin name. (Refer to the table Global Variables.) The description, DUALSEL_S2 Description,becomes the prefix of the block input/output descriptions. The FormatSp Attribute Name Value, TempFS, is the formatspecification of the block output. The DLFormatSp Attribute Name Value, TempDiffFS, is the format specification of theblock DL pin output.

Note The only exception to the rule is the output pin ({Device}) where the global pin name is in the form Device Value pinname without the " ".

FUNC Fungen_T

Function to generate the following:

• Step (1) drives the output to MAX_VAL in one sweep• Square wave (2) oscillates between MAX_VAL and MIN_VAL, holding MAX_VAL for

PERIOD1 and MIN_VAL for PERIOD2. The sequence always begins with MAX_VAL• Ramp (3) ramps the output to MAX_VAL. If the output is less than MAX_VAL the

ascending ramp rate, A_RATE is used. If the output is greater than MAX_VAL thedescending ramp rate D_RATE is used.

• Triangle wave (4) repetitively ramps from MAX_VAL to MIN_VAL at D_RATE andback to MAX_VAL at A_RATE. At startup if the output is greater than MAX_VAL thedescending cycle will commence first. Otherwise the ascending cycle will commencefirst

• Sine wave (5) generates a sinusoidal wave between the amplitudes of MAX_VALand MIN_VAL with a period of PERIOD1. The waveform commences at 0 degreesregardless of the initial output value (default value is Step.

MAX_VAL REALMaximum value of the output (unless the initial value of the output is already greater thanMAX_VAL). For proper operation MAX_VAL should be greater than or equal to MIN_VAL

21 Interpolator Version 2 (INTERP_V2)Block Category: Controls (Basic)

The Interpolator Version 2 (INTERP_V2) block generates an output as a function of IN by linear interpolation. The argumenttable X[N] is searched using IN as the key. OUT is calculated from the function table Y[N] using the search index from theargument table and interpolating between the values:

OUT = Y[i] + ((Y[i+1] - Y[i]) x ((IN - X[i]) / (X[i+1] - X[i]))),where i is the index resulting from the binary search of the argument table.

The array sizes of the variables attached to X[ ] and Y[ ] must be equal to or greater than the table size specified by N and thetable size must be greater than or equal to 2. If either of these conditions is not met, a build error is generated. OUT isclamped to either the first or last element in the function table if IN is not within the range of the argument table elements.When IN is within the limits of the argument table, the slope, M, is calculated as follows; otherwise, M is defined to be theslope of a line between the nearest function table end point element and the element next to it:

ERROR is False under normal operation but is set to True if an error is detected. If the value of IN is a NaN or if the elementsof X[] are not monotonically increasing, ERROR is set to True. If ERROR is True, OUT is not updated.

24 Logic Builder State Change (LOGIC_BUILDER_SC)Block Category: Permits and Overrides

This block allows up to 32 inputs to be configured with the AND, OR, and NOT blocks to create a PERMIT, OVERRIDE,FORCE, or TRACK type block. Unlike the normal PERMIT, OVERRIDE, FORCE, or TRACK blocks that essentiallyfunction as either an AND or OR block, this block allows the user to create unique logic scenarios that can contain up to 32individual inputs and up to six logic blocks in series of depth using any combination of AND, OR, and NOT blocks.

The LOGIC_BUILDER_SC block provides a simple, versatile, and effective solution to provide FORCE, OVERRIDE orPERMIT applications for complex situations. Each of the 32 inputs has a corresponding attribute set by the programmer,which, when changed, must be downloaded to the controller. The input attribute either permits or does not permit theoperator’s ability to enable or disable the associated input using the CIMPLICITY graphical interface. The LOGIC_BUILDER_SC block type, PERMIT, OVERRIDE, FORCE, or TRACK is controlled by an enumerated input, TYP, which isset by the programmer. The enumeration selected for the TYP input determines the enumerations the block will output fromthe OUT block output. The output enumerations will correspond to the type of block specified by the TYP input enumeration.

Each input has the capability of inheriting the description of a connected global variable or a global variable connectedthrough a NOT block. When a connection is made to one of the input pins, the description of the global variable is inheritedby default. If this description is undesirable, it must be disabled by setting the Inherit Description option to False in the inputvariable properties. The description can be replaced with a desirable description by entering an appropriate description in thedescription field of the input variable of the LOGIC_BUILDER_SC block (replace LOGIC_BUILDER_SC #1 with thedesired override description for the source connected to IN1). The description is not copied from the connected variableimmediately; the input’s description is set when the library or device containing the input is validated or built.

Equation (EQN) Input

The equation input, EQN, is a string equation that is equivalent to the graphical AND, OR, and NOT blocks used to representthe logic required to provide the correct block output (* = AND, + = OR, ~ = NOT, () are grouping characters). The stringequation can be entered directly into the input EQN, or it can be generated automatically from the graphical representation ofthe logic created using AND, OR, and NOT blocks. If the equation is entered manually into the EQN input, the logic isautomatically configured correctly in the logic building template and visa versa.

Example: EQN input; (IN1+IN2)*(~(IN3))

Example EQN Input

Logic Building Template


IN1, IN1TP, IN1TE, and IN1T (1-32) Inputs

Inputs IN1 through IN32 are manipulated by AND, OR, and NOT logic to create the desired output.

Input toggle permits, IN1TP through IN32TP , are set by the programmer and can only be changed in the controller byperforming a Build and Download of the modified code. If the toggle permit input for a corresponding input is True, theoperator is able to toggle the value of the associated logical input, IN1TE through IN32TE, using the CIMPLICITY graphicalinterface.

Inputs IN1TE through IN32TE are toggle enable inputs that are controlled by the operator using the CIMPLICITY graphicalinterface. The operator can toggle each permitted input from True to False, or False to True.

The toggle input values, IN1T through IN32T, track the values of IN1 through IN32, respectively, when toggle mode is notenabled for its input. The toggle input value, IN1T through IN32T, is the actual value that is used in the AND, OR, and NOTprogrammed logic. The toggle value, IN1T, for the IN1 input is defined as a combination of the toggle input permit, IN1TPbeing equal to True, and the toggle enable input from the CIMPLICITY graphical interface, IN1TE being equal to True. Thistoggle value concept is True for all 32 inputs, IN1 through IN32.

Output (OUT) Enumerations

The output, OUT, is an enumerated output. The enumerations for OUT are based on the block type dictated by the inputenumeration assigned to the input TYP, and will be a PERMIT, OVERRIDE, FORCE, or TRACK type enumerations. OUToutput enumerations are defined by type, either PERMIT, FORCE, OVERRIDE or TRACK.

Outputs OUT_TGL and OUT_VAL

The output, OUT_TGL, indicates one or more of the inputs are in toggle-enabled mode. OUT_TGL is True when at least oneIN1TP and IN1TE through IN32TP and IN32TE pair is True. When OUT_TGL is True, the OUT enumeration containsBYPASS or BLOCK based on the enumeration chosen for the block by the input TYP.

OUT_VAL, the Boolean output status, is driven by the logical output of the user-defined equation input, EQN. When OUT_VAL is True, the OUT enumeration contains either PERM, OVR, FORCE or TRACK based on the enumeration chosen forthe block input TYP.



When a block is inserted into the ToolboxST application code, it generates a window prompting the user to enter the DeviceName and the Block Type that will be assigned to the TYP input. The block automatically creates the variables associatedwith the block and provides the appropriate attributes for each variable (for example Type, Scope, variables that need to be onEGD will be automatically placed on the $Default EGD page).

HMI Configuration (CIMPLICITY)

The following figure is an example of the CIMPLICITY graphical interface with a permit type block, with six permit enabledinputs and input 2 is toggled.

Typical HMI Object for LOGIC_BUILDER with a Permit Type Block

The following figure is an example of the common usage of a LOGIC_BUILDER block. This example displays the LOGIC_BUILDER block sharing the same name as the M_O_V block that it is controlling. The ToolboxST application requires thatall blocks have unique names. The LOGIC_BUILDER blocks avoid this by adding the block type to the block name. Thismakes them unique, links them to the block they control in the HMI, and indicates their function.


Connection and Naming

State Change

The State Change feature performs a First In-First Out (FIFO) operation for all 32 inputs. It latches input values for thecurrent and previous frames when the output transitions to a Not Permitted, Forced, Override, or Track state. Indication isprovided that a State Change has occurred and acts as a reset dominant latch.

Each input has the capability of inheriting the description of a connected global variable or a global variable connectedthrough a NOT block. When a connection is made to one of the input pins, the description of the global variable is inheritedby default. If this description is undesirable, it must be disabled by setting the Inherit Description option to False in the inputvariable properties. The description can be replaced with a desirable description by entering an appropriate description in thedescription field of the input variable of the LOGIC_BUILDER_SC block (replace LOGIC_BUILDER_SC #1 with thedesired override description for the source connected to IN1). The description is not copied from the connected variableimmediately; the input’s description is set when the library or device containing the input is validated or built.

The State Change feature adds the input pins SCA_ENABLE, RESET, and RESET_PB. The SCA_ENABLE pin must beTrue for the State Change feature to operate. This would typically be connected to device I/O to prevent recording a StateChange while the equipment is not operating. For example, it may not be desired to record a process trip to a pump if thepump was already off when the trip signal was sent.

The RESET pin is available for control logic to reset the SCA pin. While the RESET pin is held True, the SCA pin willremain False. It might be desirable to set this input True for one frame when a sequence or system is initially started.

The RESET_PB pin is intended for use by the CIMPLICITY graphical interface. When the RESET_PB pin is set to True theSCA pin is set to False, then RESET_PB is set to False by the LOGIC_BUILDER_SC block.

The State Change feature adds the outputs pins SCA, SCA_CUR, and SCA_PRV. The SCA pin changes from False to Truewhen the OUT pin transitions to a Not Permitted, Forced, Override, or Track state. The SCA pin acts as a reset dominantlatch. The RESET and RESET_PB pins reset the SCA latch. The SCA_ENABLE pin prevents the SCA latch from being set,but will not reset the SCA latch.

The SCA_CUR pin holds a 32-bit un-signed integer. The value of each bit of this integer represents the value of thecorresponding input, for the frame the OUT pin transitioned to a Not Permitted, Forced, Override, or Track state.

The SCA_PRV pin holds a 32-bit un-signed integer. The value of each bit of this integer represents the value of thecorresponding input, one frame before the OUT pin transitioned to a Not Permitted, Forced, Override, or Track state.

28 Median Select Version 2 (MEDSEL_S2)Block Category: Analog Operations

The Median Select Version 2 (MEDSEL_S2) block selects the median or average of three analog signals based on theenumerated value of the input TS and transfers the selection to the output ({Device}). The user has the option to disable up totwo transmitters. If one transmitter is disabled, the output will be either the minimum, maximum, or average of the tworemaining transmitters based on the enumerated value of the input, DS. If the one transmitter allowed property, 1XMTR_P, isTrue, two transmitters can be disabled and the output will be the value of the remaining transmitter.

This block is similar to the Mark VIe block MEDSEL_V2 but functionality differs in the following ways:

• The MEDSEL_S2 block does not support the status option.• The Auto Enable (AU_EN_P) feature is not supported.• Control commands for disabling and enabling transmitters are supported in the MEDSEL_S2 bock; however, the

push-button reset functionality must be implemented in another device. For further details, refer to the description ofcontrol word (CTL_EXT) in the section Control Word.

Block Configuration

Disabling Transmitters

When the quality status of transmitter A is BAD (False), then ABQ and AD become True and transmitter A is automaticallydisabled. Also, depending on the DS enumeration selected, the average, minimum, or maximum of inputs B and C istransferred to OUT. Once the quality status of transmitter A becomes GOOD (True), ABQ becomes False. If the quality statusof transmitter A becomes GOOD (True) and the value of input A is within the deviation limits set by the user, AD becomesFalse and A is automatically enabled. This concept also applies to inputs B and C.

A transmitter can be manually disabled through the CTL_EXT input. If input A, B, and C are all enabled and have a GOODquality status, and A is manually disabled, then the corresponding output, AD, becomes True to indicate that input A isdisabled. If input A is enabled and B is disabled, then BD is True. If input B is enabled and C is disabled, then CD is True.

Output Bad Quality Indication (OBQ) functionality is as follows:

If 1XMTR_P is True, when three transmitters are disabled and/or in a BAD quality state, OBQ becomes True, the defaultvalue, DF, is automatically transferred to the output, and MODE is set to DEFAULT.

OBQ becomes False when the quality status of any input becomes GOOD. The GOOD quality input will be enabled andtransferred to the output.

If 1XMTR_P is False, when two or three transmitters are disabled and/or in a BAD quality state, OBQ becomes True, thedefault value, DF, is automatically transferred to output, and MODE is set to DEFAULT.

OBQ becomes False when the quality status of two inputs become GOOD. The GOOD quality inputs will be enabled andbased on the DS enumeration selected, the average, minimum, or maximum of the GOOD quality inputs is transferred to theoutput.

Control Word

Control word (CTL_EXT) is used by the HMI operator for manual control. The manual commands from the HMI allow eachinput to be enabled or disabled. A manually disabled transmitter can be manually enabled, regardless of its deviation status.The command enumerations are defined in the following table.

Note A manually disabled transmitter may be manually enabled, regardless of its deviation status, unless the block is inAverage mode. For further details, refer to the section Deviation Alarms.


CTL_EXT Enumerations

Enumeration CommandNO_CMD No Command

EN_A_CMD Enable Input A Command

DIS_A_CMD Disable Input A Command

EN_B_CMD Enable Input B Command

DIS_B_CMD Disable Input B Command

EN_C_CMD Enable Input C Command

DIS_C_CMD Disable Input C Command

Note Operation of the CTL_EXT pin in the Mark VIeS control differs from that in other Mark VIe control products. In theMark VIeS control, the variable attached to the CTL_EXT pin must be from a consumed EGD page. The EGD producerdevice driving the variable must implement the necessary push-button reset logic.

Commands are only accepted by the block if a transition from NO_CMD to a command value is detected while the CTL_EXT input is healthy. After a command is accepted by the block, the CTL_EXT pin is ignored for a period of two secondsafter which a valid transition from NO_CMD must be detected to accept another command. An example configuration is asfollows:

Example Configuration

An HMI faceplate is created to display data from the MEDSEL_S2 block from a Mark VIeS control. EGD signals areconsumed by the HMI from the Mark VIeS control and are used to drive the faceplate. The control word from the MarkVIeS control is used for feedback. Control commands are sent to an EGD signal driven from a Mark VIe device. Forexample, after adding the MEDSEL_S2 block to the Mark VIeS control system and attaching the EGD signals to thefaceplate, the following configuration is required:

In a Mark VIe device:• Create a control word variable.• Add the control word variable to a produced EGD page.• Add push-button reset logic in the blockware to reset the control word value to NO_CMD (0). The control word should

be reset after one second of it being non-zero.

In the HMI:• Attach the control word variable from the Mark VIe control to the control word logic in the appropriate MEDSEL_S2

faceplate.

In the Mark VIeS device:• Attach the control word variable from the Mark VIe control to the CTL_EXT pin of the appropriate MEDSEL_S2

block.

Examples

• MEDIAN or AVG_ABC mode is selected when none of the transmitters have a BAD quality status.• AVG_A-B mode is selected when a BAD quality is detected on transmitter C or when C is manually disabled, and the DS

enumeration is AVG.• MIN_A-B mode is selected when a BAD quality is detected on transmitter C or when C is manually disabled, and the DS

enumeration is MIN.• MAX_A-B mode is selected when a BAD quality is detected on transmitter C or when C is manually disabled, and the

DS enumeration is MAX.• A mode is selected when 1XMTR_P is True and B and C transmitters are disabled.• DEFAULT mode is selected when all transmitters are BAD quality and/or disabled or 1XMTR_P is False, and two

transmitters are BAD quality and/or disabled.

Deviation Alarms

Each transmitter value is compared with the output to determine if it is outside of the deviation limit, DL. If so, the deviationhigh alarm for the deviant input DA, DB, or DC, for transmitters A, B, or C respectively, and ODH become True, delayed bythe deviation time delay, DT.

The deviation alarms will not become False until the absolute difference between the deviant input and the output is less thanthe value of DL minus Deviation Limit Deadband (DLDB), or the deviant input is disabled.

Note The Deviation High output, ODH, becomes True when at least one transmitter is in deviation. Also, if a transmitterinput is disabled, the deviation alarm for that transmitter is disabled.

In general, the deviation alarm only sets Boolean outputs and has no influence on the functionality of the block (for example,the transmitter in deviation with the output is not automatically disabled, and the block mode does not change).

However, if the block is calculating the average of all three transmitters (all three transmitters are enabled and TS = AVG), atransmitter that gets a high deviation will be automatically disabled immediately (ignoring the value of DT). The highdeviation alarm will be True for a single block execution. It will be enabled when the absolute difference between the deviantinput and the output is less than the value of DL minus DLDB.

Rate of Change Restriction

The rate of change of the output is only restricted by the value of RATE when the block operating mode changes.

RATE is in engineering units per second. For example, if 1XMTR_P = True, RATE = 1, A = 10 (enabled), B = 25 (disabled),and C = 50 (disabled), so MODE = A, and the mode of the block is changed by enabling input B and disabling input A. Now,MODE = B and the output increases from 10 to 25 engineering units in 15 seconds. At this point, the output equals B, theblock operating mode transition from A to B is complete and the rate of change restriction on the output is removed until theblock operating mode changes again.


Inserting the MEDSEL_S2 block in the application program displays the Enter the Attribute Instance Values window,prompting the user to enter the device description, device name, and format specification in the Values column. The blockthen automatically creates the variables associated with the block and provide the appropriate attributes for each variable (forexample, Type and Format Spec variables that need to be on EGD will automatically be placed on the $Default EGD page,and so forth).



Enter the Attribute Instance Values Window

For this example, accept the default options for these attributes. The Device Name is 00MEDSEL_S21000, the description isMEDSEL_S2 Description, and the format specification is TempFS.

When the user clicks OK, the block and pin connections are automatically configured and Global pins are generated. Pinnames are in the form Device Value.pin Name, where Device Value has the attribute value 00MEDSEL_S21000 and Input_Name is the block input/output name. (Refer to the table Global Variables.) For this example, the descriptionMEDSEL_S2Description becomes the prefix of the block input/output descriptions. The FormatSp Attribute Name Value in the previousexample, TempFS, is the format specification of the block output. The DLFormatSp Attribute Name Value, TempDiffFS, is theformat specification of the block DL pin output.

Note The only exception to this rule is the output pin ({Device}), where the global pin name is in the form Device Value.pinName without the " ".

Once the object has been added successfully, the block displays in the ToolboxST application as displayed in the followingfigure.

29 Move (MOVE)Block Category: Type Conversion

The Move (MOVE) block transfers the value of the input variable, SRC, into the output variable, DEST. The data transferoccurs each time the block runs and the ENABLE pin is True. The analog variants of the block can be used to perform datatype conversions, as well as memory move operations. The Boolean variant of MOVE is used to move only a logical state andcannot convert the data type.

The MOVE blocks are useful for taking snapshots of data that are shared between tasks in separate modules. Moving thevariable to local copies guarantees that a high priority task cannot change the shared data while the low priority task isprocessing it.


The MOVE block does not allow a NaN to pass through it. If a NaN is encountered on an input pin, it is replaced at the outputwith either the most positive or most negative representable number, based on the sign of the NaN.

Note This is a variant block that supports any one the following block data types: BOOL, INT, DINT, REAL, LREAL,UINT, and UDINT. The data type of the DEST pin must match the selected data type of the block. Refer to the section .

32 Pulse (PULSE)Block Category: Sequencing

The Pulse (PULSE) block generates a Boolean one-shot of the specified width (WIDTH in milliseconds) at the output pin onthe rising edge of the trigger. Once the pulse is initiated, it persists until it times out regardless of the value of the trigger. Theprevious state of the trigger is stored with each execution sweep so the falling edge of the next trigger may be seen prior to theend of the pulse. A specified pulse width of 0 results in a one sweep pulse. The Pulse width is always a multiple of the frameexecution period set in the ToolboxST application. For accurate execution of the block, set WIDTH as a multiple of the frameexecution period.

35 System Outputs (SYS_OUTPUTS)Block Category: System

Note Only one instance of this block is allowed per controller.

The System Outputs (SYS_OUTPUTS) block provides a command interface between the application code and the I/Osubsystem (that is, I/O packs). The command input Booleans are synchronously transmitted to every I/O pack. The commandsare interpreted as level values by the I/O packs and so should not be kept in the True state, but rather pulsed for a few framesand then reset.

36 Temperature Status (TEMP_STATUS)Block Category: System

The Temperature Status (TEMP_STATUS) block is a temperature-sensing block for the Mark VIeS Safety controllers. Alltemperatures are in degrees C. The outputs from this block are dependent on controller platform. TEMP_STATUS is notsupported in the Virtual Controller, where all the outputs default to a value of zero and ALARM defaults to False. TEMP_STATUS does not generate any diagnostic alarms.

Notes on Legacy Controller Functionality

With UCCC controllers, the CPU_TEMP pin outputs the CPU core temperature. The BRD_TEMP pin outputs themotherboard temperature. two temperature sensors are embedded in the processor card as well, TEMP1 and TEMP2. Onesensor is placed near a resistor so that it is constantly warmed above the ambient temperature. The other is placed away fromany heat-producing elements. When the fan is on, the airflow provides cooling around both sensors and a relatively constanttemperature difference, DELTA, measures the difference between the two. When the fan is off the warmed sensor experiencesa much larger rise in temperature than does the ambient sensor. All three variables, TEMP1, TEMP2, and DELTA are outputfor diagnostic purposes and backward compatibility, but they no longer contribute to the alarm logic.

With UCCC controllers, the TEMP_STATUS block uses a default temperature, DEF_THLD, to determine an uppertemperature alarm limit. This limit can be replaced with a user configurable limit, THLD, if the user enables Boolean inputUSR_ENA. Once in ALARM, the Boolean condition will not reset until the CPU temperature falls below the uppertemperature alarm limit less a hysteresis value. This hysteresis value defaults to a supplied value DEF_HYST, unless theBoolean input USR_ENA overrides this value with the input HYST. Default temperature limits are determined by GE for theparticular platform. Current EPMC values are: DEF_THLD = 90, DEF_HYST = 5°C. The user is given another Booleaninput pin, OTPROT, to control action when an alarm condition is detected. If an alarm condition latches when OTPROT isTrue, the controller automatically reboots into a low power failure mode. The application will not run in this mode, but toolconnectivity is maintained. After a subsequent reboot, the application will run again.


37 Timer (TIMER)Block Category: LEGACY, Timers and Counters


The Timer (TIMER) block accumulates incremental time into CURTIME while RUN is True. When CURTIME is equal toMAXTIME, AT_TIME transitions to True. If RUN is False then timing is suspended but CURTIME holds its value. IfRESET is True then CURTIME is set to zero and counting is suspended. The AUTO_RS flag can reset the timer after itreaches MAXTIME. In this mode, AT_TIME will be True for one scan and the CURTIME will be set to the residual count sothat no time is lost.

The time period taken by the output pin AT_TIME to transition is always a multiple of the frame execution period set in theToolboxST application. For accurate execution of the block, set MAX_TIME as a multiple of the frame execution period.

The maximum value of mCurTime in the TIMER block can be 4294967295ms (0xFFFFFFFF).

38 Timer Version 2 (TIMER_V2)Block Category: Timers and Counters

The Timer Version 2 (TIMER_V2) block accumulates incremental time into CURTIME while RUN is True. WhenCURTIME is equal to MAXTIME, AT_TIME transitions to True. If RUN is False then timing is suspended but the value inCURTIME remains. If RESET is True then CURTIME is set to zero and counting is suspended. The AUTO_RS flag can resetthe timer after it reaches MAXTIME. In this mode, AT_TIME will be True for one scan and the CURTIME will be set to theresidual count so that no time is lost.

The time period taken by the output pin AT_TIME to transition is always a multiple of the frame performance period set inthe ToolboxST application. For accurate performance of the block, set MAX_TIME as a multiple of the frame performanceperiod.

The maximum value of mCurTime in the TIMER block is 4294967295ms (0xFFFFFFFF).

39 Unit Delay (UNIT_DELAY)Block Category: Controls (Basic)

The Unit Delay (UNIT_DELAY) block performs a one-frame delayed copy of the input, IN, to the output, OUT. The timeperiod of the delay depends upon the Frame period with which the block is being executed.

Note This is a variant block which supports any one the following block data types: BOOL, INT, DINT, REAL, LREAL,UINT, and UDINT. The default data type is REAL. To modify the data type, refer to the section Change Data Type of VariantBlock.

40 Variable Health (VAR_HEALTH)Block Category: System

The Variable Health (VAR_HEALTH) block receives from 1 to 32 variable signals as input points to this block. For eachconfigured input, this block provides two corresponding output pins that provide both the health status (HEALTHnn) and linkstatus (LINKOKnn) of the corresponding input.

The available 32 input pins can be assigned to any of the following variables:

• Regular variable directly from an I/O board input signal• Variable from an external network, such as a variable assigned to a Unit Data Highway (UDH) EGD page• Regular variable directly from an I/O board output signal (not usually required)• Internal state variable (rarely needed)

Inputs

Name Data Type DescriptionVAR1 Simple Input variable to know the health status↓ ↓ ↓VAR32 Simple Input variable to know the health status

Outputs


HEALTH1 BOOL Input 1 healthyLINKOK1 ↓ Link OK for EGD variable 1HEALTH32 ↓ Input 32 healthyLINKOK32 BOOL Link OK for EGD variable 32

When a variable VARnn is believed to be working properly, the corresponding output pins HEALTHnn and LINKOKnn areboth set to True. This happens when all tests defined for its source are completed successfully. This includes both variablesignal connectivity as well as any healthy/unhealthy determinations made by the specific I/O pack.

The HEALTHnn output provides an indication of the health of the corresponding variable VARnn. If the Ethernet cable isunplugged from a simplex analog input I/O pack, this causes a connectivity issue resulting in the HEALTHnn variable beingset to False to indicate an Unhealthy signal. The I/O pack can set the HEALTHnn variable to False for other conditions, suchas if an input configured as a 4–20 mA analog input has its input current out of range.

I/O points transition from Unhealthy to Healthy the first frame they are received Healthy from the I/O module.

Note For input health information to be viewable in a live data display, for example in Live View, Trender, or the blockwareeditor, the input must be connected to either a VAR_HEALTH or AI block. Refer to the table, Output Pin States.

If LINKOKnn is True, the controller has successfully received the EGD data packet from the I/O pack or other source. IfLINKOKnn is False, the EGD data packet has not been received and HEALTHnn will always be False as well.

Each configured VARnn input on the VAR_HEALTH block also has a separate output pin, LINKOKnn, even though it is acomponent of the overall health. The LINKOKnn output applies to all of the data from a particular device and may be used asan indication of electronic hardware health (for example, I/O pack health).

The HEALTHnn output for each variable provides the instantaneous status of the variable input. A healthy value on theHEALTHnn output implies a healthy input pin. However, any user application code should allow an appropriate time beforeresponding to a transition from healthy to unhealthy. All Ethernet communication links have a bit error rate, so occasional lossof a single EGD packet on an Ethernet network is considered normal and expected. The HEALTHnn output can go False afteronly a single period loss of communication. In most applications that monitor variable health, it will be necessary to add a (1)time delay or (2) period counter or (3) loss-counts-per-time-interval counter to the detected unhealthy transition based on thespecific needs of that I/O variable. Refer to the section Output Health Status Details for detailed timing.


Note A period refers to the time between consecutive transmissions of the variable. For most variables from I/O packs, theperiod corresponds to the frame rate, although certain I/O packs such as PSCA do not always transmit at frame rate. Forvariables that derive their health from the health of a received EGD page from another controller, the period depends on theframe rate of the transmitting source and the associated page period multiplier. From the ToolboxST application, select theEGD tab to view the Period information.

Output Health Status Details

I/O pack variable sources— the VAR_HEALTH output status goes unhealthy during the first period in which the controllerdoes not receive a healthy indication from the source I/O pack.

• For a network with simplex redundancy, the VAR_HEALTH output status goes unhealthy after the loss of the only inputdata packet.

• For a network with dual redundancy, the VAR_HEALTH output status goes unhealthy after the loss of both input datapackets.

• For a network with TMR redundancy, the VAR_HEALTH output status goes unhealthy after the loss of the second inputdata packet.

This unhealthy status could be caused by a communication failure with the I/O pack or by the I/O pack's determination thatthe signal is unhealthy based on conditions specific to that type of I/O pack and input.

External network/EGD page sources— including variables received over the UDH or Control Data Highway (CDH) usingEGD pages, the corresponding HEALTHnn output on the VAR_HEALTH block for an input variable does not go unhealthyafter the loss of a single input data packet containing that variable. Instead, the corresponding HEALTHnn output goesunhealthy during the fourth unhealthy period. Since EGD pages can be configured to run at different rates, the health of thevariable is verified once each period as configured for that EGD exchange. Each time an EGD exchange is received, theassociated input variables in that exchange are set to healthy status and a timeout timer for that exchange is set to four. Thistimeout timer is then decremented each time the configured time interval occurs. If the timeout timer reaches zero, all inputvariables in that exchange are set with an unhealthy status and the counter remains at zero until the EGD exchange issuccessfully received again.

Note If the VAR_HEALTH block has an anti-voted variable connected as an input, the corresponding VAR_HEALTHoutput behaves the same as if the system has simplex redundancy, regardless of the actual redundancy of the system.

Single Network I/O Pack Input Response to Loss of Input

When an input on an I/O pack goes unhealthy, the input value holds the previous healthy input state for the first four periods.After this, the value is set to the default value.
