1.1 Overview CTEL system

Festo can assist you in solving your automation task at themachine level with the aid of valve terminals and I/O mod-ules.The CTEL master module from Festo permits connection ofdevices with an I-port interface (I-port devices) to a CPX sys-tem.Up to 4 devices per CTEL master module can be integratedinto the CPX system.

Fig. 1/1: Principle of CTEL system



A CTEL system consists of the CTEL master module and thedevices that are connected to the master module over spe-cified I-port connecting cables. In this way, it is possible todecentralise the arrangement of the devices. The compactvalve terminals and I/O modules with I-port can thus bemounted very close to the cylinders to be controlled. Thismeans that the length of the air supply lines can be reduced.

Short compressed air lines minimise the friction lossesand the times for pressurising and exhausting the tubes.

This enables smaller valves with sufficient flow to be used,thereby helping to reduce costs.



1.1.1 Mode of operation of the CTEL system

CTEL systems are composed of the following modules:

Modules Functions

CTEL master – Are components of a CPX system andserve as gateway between CPX andI-port modules.

– Provide connections for up to 4 valveterminals or I/O modules per mastermodule.

– Transmit control signals to the con-nected modules and monitor theirability to function.

I-port valve terminals – Make available various valve func-tions for controlling pneumatic actu-ators.

– Relay plates, pressure zone separa-tion plates and blanking plates canalso be integrated.

I-port input modules – Make available inputs for connectingsensors and enable interrogation ofcylinder positions, for example.

Other I-port modules

Tab. 1/1: Overview of CTEL modules



Each CTEL master module controls the data transfer to thedecentralised I-port I/O-modules in a CPX terminal.In principle, several CTEL master modules can be placed in aCPX terminal.

The number of CTEL master modules that can be placed in aCPX terminal is limited by the available address space of theCPX terminal of up to 64 bytes of inputs and 64 bytes of out-puts.

1.2 I-port

The CTEL master module has 4 I-port interfaces. I-port is aninterface for the exchange of serial data for the connection ofdecentralised function modules (devices) from Festo at fieldlevel. It is based on the IO-Link technology and is compatiblewith it in certain areas.

The limitations compared to the IO-Link standard are, amongothers:

– Permanently set baud rate of 230.4 kBit/s.

– SIO mode is not supported.

– The maximum length of the process data is limited to32 bytes input data and 32 bytes output data.

– Only one extract of the master commands is used.

– “Plug&work” principle, configuration over IODD is notsupported.

The kind of connection corresponds to a star topology. Thatmeans, only 1 device can be connected to each I-port.

1.2.3 I-port connecting cables

Operation in accordance with specifications is guaranteedonly if original Festo connecting cables are used.For operation in accordance with specifications, the maximumlength of the I-port connecting cables must always be ob-served (see section 2.3).



1.3 Display elements

The CTEL master module is equipped with seven displayLEDs, with whose help the current status (operating status) ofthe CTEL system and the devices connected to it can be de-termined.

Lights up red Device error. Several causes are possible:– Connection to the device interrupted.– Error in the I-port communication.

Flashes red Compatibility error. Several causes are possible:– An incompatible device is connected to the corresponding I-port.– The corresponding port is deactivated, but a connected device is

recognised.

All four LEDs flashingred

Configuration error. Several causes are possible:– Invalid configuration (e.g. through exceeding of the available

address space).– Device was not replaced by another device type, system restart

necessary (only for automatic configuration).

Tab. 1/3: Significance of the display LEDs



Monitoring of the load supply voltage (PL) takes place in thedevices and is passed on to the CTEL master module.Since all connected devices use this LED, the display of anerror has priority over the display “OK” (LED lights up green).The I-port at which the error occurred can be determinedthrough the FMT/MMI using the diagnostic messages.Information on eliminating the displayed errors can be foundin section 4.2.2.



1.4 Addresses

The CTEL master module can make available a total of up to32 bytes for inputs and 32 bytes for outputs. The preciseamount of the I/O bytes made available depends on the re-quirements of the connected devices or of the correspond-ingly selected operating mode.

1.4.1 I/O configuration presettings

The address space that the CTEL master module makes avail-able and assigns accordingly in the CPX system can be con-figured according to 13 different presettings (see Tab. 1/4).These presettings correspond to the selection options thatare supported within the configuration files for the respectivehost system (see section 2.6).There are 4 presettings available in each case for operationas “pure input module”, “pure output module” and for“mixed operation”.In addition, there is a configuration for operation without con-nected devices.

Tab. 1/4: Possible I/O configurations

The I/O lengths listed here are the sum of the bytes availablefor all I-ports together.

Which of these configuration presettings the CTEL mastermodule uses can be determined manually (through the user)or automatically (through the module itself ), dependent onthe operating mode.



1.5 Operating modes (selection of the I/O configuration presetting)

Users can determine the I/O configuration presettings usedby the CTEL master module themselves (operating mode“Manual configuration”) or have it determined automaticallythrough the module (operating mode “Automatic configura-tion”).

Selection of the operating mode and the setting for the manu-al configuration takes place via the DIL switches on the leftside of the module, directly below the housing cover. Theseare only accessible if the module is removed from the CPXsystem.

Fig. 1/7: Position of the DIL switches

The operating mode of the CTEL master module (automaticconfiguration or manual configuration) is determined with theDIL switches 1.1 and 1.2 (see Tab. 1/5).

With the DIL switches 2.1 and 2.2, the I/O length, i.e. theavailable I/O bytes per I-port, are determined in the manualconfiguration (see Tab. 1/6). In automatic configuration, thesetting of these two switches is not relevant.

In the manual configuration, the established I/O length al-ways applies for all 4 I-ports (max. 8 bytes per I-port).In the automatic configuration, the I/O length for each I-portis determined individually and with the determined value thesuitable or next higher configuration presetting is selected(see section 1.4.1 or section 3.1.2).

2.1 General instructions on installation

WarningAccidental movements of the connected actuators andloose tubing can cause injury to persons and/or damageto property.

Before carrying out mounting, installation and mainten-ance work, switch off the following:

– Compressed air supply

– Operatingvoltagesupply for theelectronics/sensors

– Load voltage supply for the outputs/valves

CautionElectrostatically sensitive devices!

• Do not touch any components.

• Observe the handling specifications for electrostaticallysensitive devices.

They will help you avoid damage to the electronics.

NoteHandle all modules and components with great care. Payparticular attention to the following:

– The specified torques must be complied with.

You can obtain information on mounting the CPX terminal inthe CPX system description (P.BE-CPX-SYS-…).

2. Installation


2.2 Mounting and dismounting of the module

The CTEL master module is designed for mounting in a CPXinterlinking block (see Fig. 2/1).

NoteThe CTEL master module does not have a separate connec-

tion block, but is designed as a complete unit.

Before the CTEL master module is mounted, the desired oper-ating mode/configuration should be set or checked with the

help of the DIL switches (see section 1.5), since they can nolonger be reached after mounting.

WarningMounting /dismounting of the CTEL master module mustalways take place in a de-energised status.

• Disconnect the corresponding CPX terminal completelyfrom the related voltage supply or switch it off.

Fig. 2/1: Mounting/dismounting the CTEL master module

2. Installation


Mounting Mount the CTEL master module as follows:

1. Put the CTEL master module into the interlinking block.Make sure that the corresponding grooves with the con-tacts on the bottom of the CTEL master module lie abovethe contact rails.

2. Press the CTEL master module carefully and without tilt-ing into the interlinking block up to the stop.

3. Only tighten the screws by hand. Place the screws so that

the self-cutting threads can be used.

4. Tighten the screws with a TORX screwdriver, size T10 with0.9 ... 1.1 Nm.

Dismounting Dismount the CTEL master module if needed as follows:

1. Loosen the 4 screws with a TORX screwdriver, size T10.

2. Pull the CTEL module carefully and without tilting awayfrom the contact rails of the interlinking block.

2. Installation


2.3 I-port connecting cables

NoteOperative malfunction due to impermissible cabling.

• For connection of the I-port devices to the CTEL mastermodule, use only the special I-port connecting cablesfrom Festo (see also appendix A.3).

• Observe that the length of the I-Port connecting cables islimited to a maximum of 20 m.

You will then avoid errors in data exchange between theCTEL master module and the connected devices.

For an operation with tool change, there are special specifica-tions that must be observed in designing the connectionlines.The interface in the connecting cable must be constructed sothat, when creating the connection, the contacts of the devicesupply voltage (24 V PS and 0 V PS) must first be energised.Otherwise, through the voltage present on the cable C/Qwhen the connection is created, a short circuit might be re-ported temporarily.

2. Installation


2.4 Connection of the devices to the CTEL master module

A total of up to 4 I-port devices can be connected to one CTELmaster module.The devices are connected via Festo I-port connecting cablesto the CTEL master module (see section 1.1 and section 2.3).

If an error occurs on several devices simultaneously, only thediagnostics/error message of the device with the highestpriority is passed on (see section 4.2.1).After this error is eliminated, the error with the next lowestpriority is displayed.The priority of the connected devices results from the numberof the used I-port. The device at I-port 1 has the highest, thedevice at I-port 4 the lowest priority in representing a dia-gnostic/error message.If the CTEL master is configured to “I/O mixed operation”,diagnostics/error messages from inputs have priority overdiagnostics/error messages from outputs.

With use of more than one CTEL master module in a CPX ter-minal, the module that is mounted closer to the CPX fieldbusmaster has the higher priority.

The result of this is that devices with process-critical func-tions must be connected to the I-ports as high a priority aspossible.

Connect devices:

1. Connect the devices to the CTEL master module corres-ponding to their priority (see above) with the I-port con-necting cables.

2. Fasten plugs and sockets of the I-port with the union nut.In this way the electrical contact is guaranteed.

3. With the identification labels (type IBS 6x10 or IBS 9x20),mark to which I-port the device is connected.In this way you can avoid confusion during later repairand maintenance work.

2. Installation


2.5 Connecting the power supply

Take the following aspects into consideration when installinga CPX system with the CTEL master module:

– Power supply (see section 2.5.1)

– Current consumption (see section 2.5.2)

– Formation of power zones (see section 2.5.3)

NoteIt is imperative that you observe the instructions in sec-tion 2.5.3 when forming power zones in the CPX terminalby means of several manifold blocks with power supply.

Recommendation:

• Provide the load voltage for the corresponding actuatorsseparately if you want to implement an EMERGENCY-OFFfunction.

NoteCheck whether pressure switch-off is also necessary for anEMERGENCY STOP function on your machine/system.

NoteObserve the instructions on earthing the I-port devices inthe description for the relevant module.

2. Installation


2.5.1 Power supply

The CPX terminal has 3 different conductors:

– VEL/SENoperating voltage supply for

– internal electronics of the CTEL master module

– internal electronics of all connected I-port devices

– VOUTLoad supply voltage for output modules (is not used bythe CTEL master module)

– VVALload supply voltage for valve terminals or other con-sumers

Interlinking blocks with power supply are used to provide thepower supply of the CPX terminal. The following designs areavailable in combination with the CTEL master:

Interlinking block typeCPX-…-EV-S… (VEL/SEN)

Offers connection options for supplying operating voltagesupply VEL/SEN , load voltage supply VOUT and load voltagesupply VVAL.

Interlinking block typeCPX-…-EV-V… (VVAL)

Offers connection options for supplying load voltage supplyVVAL.

2. Installation


NoteOperative malfunctions due to insufficient power supply.

• Supply of the load voltage supply VVAL must be suffi-ciently dimensioned to be able to supply the connectedactuators.

• Observe that, dependent on the respective length of theI-port connecting cable and current consumption of theconnected I-port device, a voltage drop results betweenthe CTEL master module and the device.Therefore, when I-port connecting cables >5 m are used,the operating voltage supply VEL/SEN should not befallen below by more than 10 %.

• The total current requirement of the CPX terminal andthe CTEL system as well as the limit values for the max-imum current intensities must be taken into account inthe design of the voltage supply (see section 2.5.2and 2.5.3).

2. Installation


2.5.2 Determining the current consumption

The current consumption of a CTEL system depends on thenumber and type of connected I-port devices.

Recommendation:

• Use a regulated power supply.

• When selecting the power supply unit, check that it hassufficient output. Calculate the total current consumption,if necessary.

Calculation Tab. 2/1 shows the calculation of the total current consump-tion for a CTEL system. Refer to the relevant technical data forthe current consumption of the I-port devices.

NoteSelect a power supply unit which provides sufficient out-put for later extensions to the CTEL system.

If you are using I-port output modules with a separate loadvoltage connection, take into account the corresponding cur-rent consumption when selecting a power supply unit.

Observe the instructions on selecting the power supply unitin the CPX system description.

2. Installation

Tab. 2/1: Current consumption from VEL/SEN of the CPX terminal

2. Installation


CautionOperative malfunctions due to exceeding of the maximumpermissible current consumption.

– Make sure that the current consumption from VEL/SEN doesnot exceed the maximum permissible value of 1.6 A.

– Make sure that the total current consumption of theCTEL system does not exceed the maximum permissible9 A (with deduction of the other consumers within thevoltage zone).

2. Installation


2.5.3 Voltage supply concept – formation of voltage zones

The modular power supply arrangement of the CPX terminalfacilitates the formation of voltage zones.

Observe the following:

– The internal electronics of the I-port devices are suppliedfrom the operating power supply for electronics/sensors(VEL/SEN).The I-port valve terminals and output modules areprovided with load voltage from the load voltage for thevalves (VVAL).

NoteThe CTEL master module must be supplied via the samepotential (common power supply unit) as the operatingpower supply for the electronics/sensors (VEL/SEN) of theCPX terminal (see also Fig. 2/2).The supply of the actuators can take place via theload voltage supply VVAL potential-isolated compared toVEL/SEN.

Basic information on the power supply arrangement of theCPX terminal can be found in the CPX system description.

You will find some specific application cases in Fig. 2/2,Fig. 2/3 and Fig. 2/4.

2. Installation


2.6 Connection with the host system

For the required connection between the CTEL master modulein the CPX terminal and the higher-order host system, it isrequired that the configuration file that corresponds to thecurrent configuration presetting of the CTEL master module isselected in the host system. Only in this case is the CTEL mas-ter module correctly recognised when the system is run up.Otherwise, no communication can be built up and no dia-gnostics/error message is output.

The possible configurations correspond to the description insection 1.4.1.

2.7 Ensuring protection class IP65/67

NoteTo comply with protection class IP65/IP67:

• Seal unused I-ports with corresponding protective caps(accessories, not included in scope of delivery, see ap-pendix A.3).

3.1 Description of the operating modes

The behaviour of the CTEL system is fundamentally influ-enced by the set operating mode. Decisive for the selection ofthe operating mode are especially

– type of installation (permanent or flexible)

– available address space (large or strongly limited)

3.1.1 Manual configuration (tool change mode)

Advantages Manual configuration of the I/Os offers the possibility toreplace the connected I-port devices during operation. I/Oconfiguration and I/O length are determined together for allI-ports. Each I-port device that corresponds to this configur-ation can be connected during operation.

For permanently established I/O lengths, observe that the con-nected modules must not exceed the set I/O lengths. Otherwise,an I-port configuration error is output (see section 4.7.2).

Select manual configura-tion

For manual configuration, it must be determined through theDIL switches S1.1 and S1.2 whether the CTEL master moduleat all 4 I-ports makes available only inputs (pure input mod-ule), only outputs (pure output module), or inputs and outputs(mixed operation). See Tab. 1/5 in section 1.5.1.

I/O lengths The I/O length is determined together for all I-ports throughthe DIL switches 2. An I/O length of 4 bytes per I-port cor-responds to a setting of 16 bytes, for example. See Tab. 1/6in section 1.5.1.

3. Commissioning


Example:The following devices should be connected to the CTEL mas-ter module at system start:

– Output module with 16 outputs (2 byte O)

– Input module with 8 inputs (1 byte I)

– Valve terminal with 32 outputs (4 byte O)


Since devices with inputs and outputs should be connected,the CTEL master module must be set to “mixed operation set(switch S1.1 and S1.2 to “ON”).

The I/O length results from the device with the highest I/Orequirements, in this case 4 bytes for the valve terminal.

Since no individual I/O lengths are possible with the manualconfiguration, an I/O length of 4 bytes per I-port, that is 16bytes (for all I-ports together) must be selected (switch S2.1to “OFF”, S2.2 to “ON”).

The configuration presetting selected through this is thus16 bytes I/16 bytes O.

In cases in which the reserved address space is not com-pletely used by the connected devices, this results in inputand output addresses (channels) to which no device input oroutput is assigned.

Unused channels Input channels to which no device input is assigned areautomatically set to the value “0” in the CPX system.Output channels to which no device output is assigned areignored in data transmission.

3. Commissioning


Sequence at system start At the start of the system, the CTEL master module checksall I-ports for connected devices and their agreement withthe selected configuration presetting.

Communication withthe host system

To make a connection set-up between the CPX terminal andhigher-order controller possible, the manual configurationpresetting of the CTEL master module must agree with therespective entry of the corresponding fieldbus configurationfile (see section 2.6).

3.1.2 Automatic configuration

Advantages No setting by the user is necessary in automatic configura-tion of the I/Os. At system start, the CTEL master moduleautomatically determines the suitable I/O configurationpresetting (see section 1.4.1). The precise sum of the re-quired I/Os are used for this so that a smaller configurationpresetting can be selected compared to the manual config-uration.

Select automaticconfiguration

To operate the CTEL master module with the “Automaticconfiguration” operating mode, the DIL switches S1.1 andS1.2 must be set to “OFF”. The position of switches S2.1 andS2.2 is not relevant thereby.

Sequence at system start Interrogation of the I-ports

At system start, all four I-ports are interrogated and thenumber of I/Os of all connected devices is determined to theprecise byte.

3. Commissioning


Selection of the configuration presetting

The sum of the determined I/Os is compared by the softwareto the available configuration presettings (see section 1.4.1).The suitable or next higher configuration presetting is selec-ted.

Example:The following devices are connected to the CTEL master mod-ule at the system start:

– Output module with 16 outputs (2 byte O)


– Valve terminal with 32 outputs (4 byte O)


Sum of the required I/O bytes:3 byte I/6 byte O

Selection of the configuration presetting:

Sum of I/O bytes Config. presettings

3 bytes I/6 bytes O …

32 bytes I/0 bytes O

8 bytes I/8 bytes O

16 bytes I/16 bytes O

…

Distribution of the assigned addresses to the I-ports is indi-vidually possible in the automatic configuration. That is, anindividual I/O length between 1 byte and 32 bytes can beassigned to each I-port for determination of the sum of theI/O bytes.But the sum of the bytes available in total remains 32 bytes.That means, if the 32 bytes are issued to an I-port, no moreI/Os are available for the other three I-ports.

3. Commissioning


Communication withthe host system

To make a connection set-up between the CPX terminal andhigher-order controller possible, it must be ensured that theautomatically determined configuration presetting of theCTEL master module agrees with the respective entry of thecorresponding fieldbus configuration file (see section 2.6).

I/O bytes are assigned in the CPX system corresponding tothe selected configuration presetting.The assigned address spaces are thereby filled “from below”,that is, the starting point is the least significant address(LSB). The unused MSBs expire.

The distribution of the device addresses to the address spaceof the CTEL master module in the examples from the sections3.1.1 and 3.1.2 would look as follows:

Through the possibility of automatic I/O configuration andexact-byte issuing of an individual I/O length to each I-port,assignment of unused address space can be considerablyreduced compared to the manual configuration.

3. Commissioning


In the example, the assigned address space in the automaticconfiguration is 8 byte I/8 byte O (12.5 % of the entire ad-dress space in the CPX system). To use the same devices inthe manual configuration, 16 byte I/16 byte O are needed(25 % of the total address space in the CPX system).

3.2 Procedure for commissioning

In order to avoid connecting and configuration errors, com-missioning in steps is required.Proceed as follows:

1. Check the CTEL master module and the connected I-portdevice (see section 3.3).

2. Determine the configuration presetting used (see sec-tion 1.4.1).

3. If required: parameterisation of the CTEL master moduleand the I-port device (see section 3.6).

4. Check voltage supplies (see section 2.5).

5. Commission the entire system.1)

1) See description for the respective CPX fieldbus master

3. Commissioning


3.3 Preparing the CTEL system for commissioning

NoteDo not yet connect the CPX terminal to a higher-order con-troller yet to prepare for commissioning.You will thus avoid addressing errors which may occur invarious fieldbus systems when address ranges are modi-fied during operation.

Please observe that host system integration of the CTEL mas-ter module might have to take place through a devicedescription file, dependent on the CPX fieldbus node used.You can find the corresponding description files atwww.festo.com.

3.3.1 Check the connected I-port devices

• Check, if necessary, the position of the DIL switches toguarantee the desired operating mode and configurationpresetting.

• Check the CTEL master module for a tight fit in the inter-linking block.

• Check whether the connected devices correspond to theentry of the configuration file on the host system (seesection 2.6).

• Check whether the connected I-port devices are distrib-uted corresponding to their priority for the diagnostic/er-ror messages at the I-ports (see section 4.2.1).

• Check whether the current consumption of the connectedI-port device and the other CPX modules corresponds tothe specifications and limits (see section 2.5).

• Check the power supply connections at the interlinkingblocks.

3. Commissioning


3.4 Behaviour of the CTEL system with operating malfunctions

If there is a malfunction on an I-port during operation, e.g.broken cable, etc., this will be indicated by flashing or illumin-ation of the display LED (X1 ... X4) of the corresponding I-porton the CTEL master module.The behaviour of the affected device is dependent on thedevice type.

Moreover, additional diagnostic information of the CTEL mas-ter module is available and can be called up both over thefieldbus used as well as via the Festo Maintenance Tool (FMT)or the Handheld (MMI), for example.

Detailed instructions on the diagnostic functions of the CTELmaster module can be found in the section 1.3 or in thechapter 4.

3.4.1 Start of the CPX terminal with system setting “Stored parameters”

If the start setting “Stored parameters” is configured in thesystem settings of the CPX terminal instead of “Standardparameters”, the current assignment of the I/O addressspace of all modules remains permanently stored in the CPXterminal.

Particularly if the CTEL master module is operated in theautomatic configuration, the following must be observed:In case of a change of the I/O assignment of the I-ports (e.g.through connection/disconnection of devices or wire break inthe I-port connecting cable) in combination with a restart ofthe CPX terminal, the error “Incorrect I/O length” is reported,since the currently existing I/O configuration of the CTEL mas-ter differs from the configuration stored in the CPX terminal.

An overview of all CPX errors can be found in section 4.2.2.

3. Commissioning


3.5 Instructions on operation

WarningAccidental interchange of the connected I-port devices.Caution with subsequent modification of the I-port assign-ment:

• Make sure that devices are not separated from oneI-port and accidentally connected to another I-port. Usethe identification labels (type IBS-6x10 or IBS-9x20) inorder to identify modules uniquely.

• Before starting the system, check whether the I-portassignment corresponds to the configuration in the hostsystem.

You can thereby avoid:

– unintended movements of actors.

WarningAccidental activation of actuators!

An incorrect status of the valves and outputs can lead todangerous situations!

• Make sure that valves and outputs are put into a safestate when malfunctions occur.

NotePlease note the following if the outputs of a valve terminal

are reset after master stop, fieldbus interruption or malfunc-tion:

– Single-solenoid valves move to the normal position

– Double-solenoid valves remain in the current position

– Mid-position valves go into mid-position (pressurized,exhausted or closed, depending on valve type).

3.6.2 Parameter “Monitoring VOUT/VVAL”

Monitoring of the supply voltage VOUT or VVAL,which is activ-ated as standard, can be deactivated with the parameter“Monitoring VOUT/VVAL”.When the monitoring is deactivated, any undervoltage thatthen occurs can be ignored. If the CTEL master already re-ports an undervoltage status (related to VOUT/VVAL), this mes-sage is deleted when this parameter is set to “inactive”.

Setting of this parameter applies for the entire module, thatis, for all I-ports equally.

3. Commissioning


3.6.3 Parameter “Behaviour after I-port short circuit”

Through the parameter “Behaviour after I-port short circuit”,the status of supply voltage can be established for an I-portdevice after elimination of a short circuit in an I-port connect-ing cable.

After the short circuit is eliminated, the power supply for thecorresponding device can

– remain switched off (setting “Leave switched-off”) or

– be automatically switched on again (setting “switch onagain”).

The parameter “Behaviour after I-port short circuit” is em-bedded as bit 7 in parameter 8. The remaining 7 bits are as-signed otherwise (see table Tab. 3/1).When the parameter for changing of the setting is overwrit-ten, the content of the bits 6…0 can be any desired. Only bit 7is evaluated for parameterisation.

With access via FMT or MMI, the parameter can be selectedand changed separately. In this way, the parameters “I/Omode” and “I/O length” can only be read.

Parameter information

The setting is made through bit 7 of parameter 8 (relativeaddress 7).

3.6.4 Parameter “I-port configuration”

Through the parameter “I-port X configuration” (X = numberof the I-port), the type of diagnostics or error control can beestablished for each I-port.First and foremost, the setting is used for monitoring whethera device is connected and, if so, whether it fits the configura-tion presetting.

At system start, the parameter is set to “Use existing device”.This setting can only be changed after the system start.

Nominal configuration Devices recognised at system start are saved as the “nomin-al configuration”. This nominal configuration remains intacteven after modification of the parameter “I-port configura-tion” and is sometimes even used by other configurations.

The following I-port configurations are available:

– Use existing device (standard setting)Operating mode “Automatic configuration”:A device recognised at an I-port during system start isstored as a nominal configuration for this I-port. When com-munication with the device is interrupted, the error “I-portdevice missing/failed” is output. If the device is replaced byanother device, this results in an “I-port configuration error”.For more information, refer to section 4.7.1.

Operating mode “Manual configuration”:Communication with the device works in a manner corres-ponding to the set I/O configuration (the device mustcorrespond to this configuration). If communication isinterrupted, an error is not output. If the device is re-placed by another device, various sequences are possible(see section 4.7.2).

3. Commissioning


– Expect device

This I-port configuration always requires a device connec-ted to the corresponding I-port.An I-port with this I-port configuration must always beconnected to a device. Otherwise, an error is output.

Operating mode “Automatic configuration”:The following scenarios are possible:

– A device was recognized at system start and stored asnominal configuration. The device is connected to“Expect device” when the I-port configuration ischanged.� Function OK.

– A device was recognized at system start and stored asnominal configuration. The device is disconnectedafter the I-port configuration is changed to “Expectdevice”.� Error message “I-port device missing/failed”.

Error is reset when the device is reconnected.

– No device was recognized at system start. The I-portconfiguration is still changed to “Expect device”.� Error message “I-port configuration error”.

All 4 I-ports are inactive.Error can only be reset through elimination of thecause of the error and a restart of the CPX system.

– Operating mode “Manual configuration”:The following scenarios are possible:A device with suitable I/O length was detected at sys-tem start. The device is connected to “Expect device”when the I-port configuration is changed.� Function OK.

– A device was recognized at system start and stored asnominal configuration. The device is disconnectedafter the I-port configuration is changed to “Expectdevice”.� Error message “I-port device missing/failed”.

Error is reset when the device is reconnected.

3. Commissioning


– At system start, a device is recognized with an I/Olength larger than the one defined.� Error message “I-port configuration error”.

Error is reset when the device is disconnected.

– No device was recognized at system start. The I-portconfiguration is still changed to “Expect device”.� Error message “I-port device missing/failed”.

Error is reset when a device with suitable I/Olength is reconnected.

– Port inactiveThe I-port is deactivated und cannot be used. A devicethat is still connected results in output of an “I-port con-figuration error”.

When the manual configuration is used, the address spaceset in the CPX system is also assigned for deactivated I-ports.

3.6.5 Parameter “Device parameter I-port”

For each connected device, 8 bytes are available for repres-entation of the device parameters. These parameters are indi-vidually interpreted by each device and are defined in thedescription of the corresponding device.

NoteObserve that the available diagnostic information maydepend on the settings of the CPX fieldbus master or theparameterisation.



4.2 Diagnostics/error messages

NoteA requirement for transmission of diagnostics/error mes-sages (if supported by the respective fieldbus) is an exist-ing connection to the host system (see section 2.6) and acorresponding parameterisation of the CTEL master mod-ule (see section 3.6).

In the operating mode “Automatic configuration” withoutconnected devices (0I/0O), no diagnostic/error messagescan be transmitted to the fieldbus master. The diagnosticdisplay in this case takes place locally through the LEDs.

4.2.1 Priorities of the diagnostics/error messages

The CTEL master module differentiates between 5 differentinstances (system + 4 I-ports) that can cause the diagnostics/error messages.

The instances have different priorities in the CPX system. Ifseveral diagnostics/error messages cannot be displayed par-allel to each other on the fieldbus side, the error messagewith the highest priority is displayed.

Priority Error instance Description

Highest System Error in the CTEL master module

• I-port 1 Error in the module at I-port 1



Lowest I-port 4 Error in the module at I-port 4

Tab. 4/2: Priorities of the error instances



The error instances of the I-ports are assigned standard to theoutputs. If no outputs are intended in the configuration of the

CTEL master module, the error instances are assigned to theinputs.

In the CPX terminal, the individual modules also have priorit-isation. This runs from the CPX fieldbus master (always com-pletely to the left) descending to the right. Modules that arecloser to the fieldbus master thus have a higher priority thanmodules sitting further to the right.

Within a CPX terminal, diagnostics/error messages with refer-ence to inputs have priority over diagnostics/error messagesof outputs. This principle of error prioritisation also finds usein the CTEL master module in the I/O mixed operation.

4.2.2 Diagnostics/error messages by CPX error numbers

Tab. 4/3 shows an overview of the CPX errors as well as pos-sible causes and information for error handling.

When the CTEL master module is accessed via FMT/MMI, themost current error for each I-port can be determined more pre-

cisely by means of an event code if the error is due to the con-nected device.

A list with the relevant event codes can be found in the ap-pendix A.2.



4.3 Diagnostics via LEDs

Display LEDs for diagnostics of the CPX terminal are availableon the CTEL master module and on the I-port devices.The description of the display LEDs on the CTEL master mod-ule can be found in section 1.3.

The significance of the LEDs on the I-port devices can befound in the description of the respective module.



4.4 Diagnostics via the CPX fieldbus master

Malfunctions of the connected I-port devices are reported tothe CPX fieldbus master as CPX error messages. Malfunctionsof the CTEL master module itself are reported as CPX errorsonly if the CTEL master in the “Manual configuration” or“Automatic configuration” operating mode is operated with atleast one device.

The following sections contain the special features of the rep-resentation for the CPX-specific diagnostics options.

– Status bits (see section 4.4.1)

– Diagnostic memory (I/O diagnostic interface, see sec-tion 4.4.2)

4.4.2 I/O diagnostic interface and diagnostic memory

The CTEL master module reports specific diagnostic informa-tion to the CPX fieldbus master.Via the I/O diagnostic interface and the diagnostic memory ofthe CPX terminal, it is possible to apply the diagnostics toindividual I-port devices. The I-port devices connected to aCTEL master module are treated as input or output channelswithin the CPX terminal.

4.7 Behaviour after lost connection to the device

With an interruption of the communication between the CTELmaster module and a device (e.g. through a wire break), theCTEL master module puts out various diagnostic/error mes-sages. These are (also) dependent on the selected operatingmode and the setting of the parameter “I-port configuration”.

4.7.1 Operating mode “Automatic configuration”

When communication with the device is interrupted, the CTELmaster module issues the error “I-port device missing/failed”(CPX error number 57).

If input bytes are assigned for the separated module in theCPX system, these are automatically set to “0”.For existing output bytes, their last known status is saved.

After an interruption is determined, the relevant I-port isqueried cyclically and checked for a connection-capabledevice.

If a device is recognised, the following procedures are thenpossible:

– The exact same device (same serial number) is recog-nised that was connected to the CTEL master moduleprior to the interruption.In this case, the error in the module is reset and the sys-tem can be further operated immediately.

– An identically constructeddevice(samenumberof I/Os,different serial number) is recognised.In thiscase, theerror in themodule isalsoresetand thesys-temcanbe immediatelyoperated further.

– Another device is recognised.An “I-port configuration error” is reported on the dia-gnostics channel of the corresponding I-port.



The “I-port configuration error” is only displayed if the powersupply of the CPX terminal has not been interrupted. Other-wise, when the system is started, the connected device isrecognised as the setpoint configuration and no error is re-ported.

4.7.2 “Manual configuration” operating mode

During operation with manual configuration, the I-ports arechecked only for the I/Os and I/O lengths that are set andassigned in the CPX system.

If the configuration parameter of the corresponding I-port isset to “Use existing device”, no error is issued.

If the configuration parameter of the corresponding I-port isset to “Expect device”, the CTEL master module issues theerror “I-port device missing/failed” (CPX error number 57)when communication with the device is interrupted.

If input bytes are assigned for the separated module in theCPX system, these are automatically set to “0”.For existing output bytes, their last known status is saved.

After an interruption is determined, the relevant I-port isqueried cyclically and checked for a connection-capabledevice.

If a device is recognised, the following procedures are pos-sible:

– The recognised device agrees with the manual configur-ation (I/Os and I/O lengths).The system can continue to be operated without limita-tion.

If the I/O length of the recognised device is less than thelength established in manual configuration, the I/O bytesused are assigned to the “lower end” of the reserved ad-dress space in the CPX system. The unassigned bytes atthe “upper end” remain unused.



Example:Manual configuration with an I/O length of 8 bytes. Con-nected is a device with an I/O length of 4 bytes. The4 bytes of the device are assigned to the first 4 bytes inthe address space of the I-port. The remaining 4 bytesremain unused.

– The recognised device has established a larger I/Olength than in the manual configurationThe system can continue to be operated. But the I/Obytes that “project” beyond the reserved address spaceare ignored.

Example:Manual configuration with an I/O length of 4 bytes. Con-nected is a device with an I/O length of 8 bytes. The first4 bytes of the device are assigned to the 4 bytes in theaddress space of the I-port. The remaining 4 bytes of thedevice remain unused.

– An output device is recognised, but the CTEL mastermodule is configured for operation as a pure inputmodule.The system can continue to be operated. Correspondingto the setting for the relevant I-port, either an I-port con-figuration error is reported (with setting “Expect device”)or no error message is issued (with setting “Use existingdevice”).The reserved input data address space is completely as-signed; all input bits are set to the value “0”.Write access to the outputs of the connected device arenot possible.

– An input device is recognised, but the CTEL mastermodule is configured for operation as a pure outputmodule.The system can be operated again. Corresponding to thesetting for the relevant I-port, either an I-port configura-tion error is reported (with setting “Expect device”) or noerror message is issued (with setting “Use existingdevice”).The reserved output data address space is completelyassigned. All write access to the output bits is ignored.Changes in status of the device inputs are also ignored.



4.8 Behaviour with error at the PL/PS supply

If the CTEL master module recognises a short circuit or over-load at an I-port on one of the related power supply cables PSor PL, the I-port involved is always switched off completely(PS and PL off).Behaviour after elimination of the error can be set via theparameter “Behaviour after I-port short circuit” (see sec-tion 3.6.3).
