1.5 Information regarding cable connection

I/O cables for digital signals

When wiring field devices, select shielded cable that is suitable for the conditions at the location of use. The possiblecable length depends on various factors. Observe the following in particular:

– the cable resistance

– the transition resistance at junctions

– the electrical characteristic values of the modules and theconnected sensors.

The maximum permissible length of the sensor cable is200 m (at min. 0.1424 mm², resistance < 50 Ω for total cablelength). The use of cables twisted in pairs increases the EMCresistance of sensor cables.

Shield support and shield earthing

Terminal connection blockCPX-P-AB-2xKL-8POL-...

These connection blocks do not feature a connection for thecable screening. A shield support or earthing (potentialequalisation) is to be configured separately.

M12 connection blockCPX-P-AB-4xM12-4POL-...

The metal thread of these terminal blocks can be used as ashield support by utilising corresponding plug connectors.The shield support is capacitively separated from the potential equalisation. If the screening is to be earthed on themodule side, a separate provision is to be provided for thispurpose.

Provided it is permitted by the national regulations for thepotential equalisation concept at the installation location,cable screenings should only be earthed at one point.

Mechanical coding system for terminal connection

To prevent connection errors from occurring during subsequent installation and maintenance work, you can mechanically code the terminal connector by using a coding system.

1. System summary


NoteIncorrect insertion is still possible, however, if mechanicalcoding is used incorrectly.

� Mark the connections and cables used for the device(colour coding and labelling) to prevent a mix-up of connections, particularly with regard to intrinsically safeand non-intrinsically safe circuits.

The coding system is optionally available (�www.festo.com/catalogue).

The coding system consists of coding tabs and coding profiles. For each contact you can:

– insert a coding profile into the groove of the plug-in blockand

– insert a coding tab into the recess of the box header.

If two coding elements meet at a contact point, insertion ofthe connector is mechanically locked for this point.

Fig. 1/6: Inserting a coding tab and a coding profile

Contacts that are not provided with a coding element (codingprofile or coding tab) do not contribute to protection againstincorrect connection.

Recommendation: Provide all contact points with a codingelement - either a coding profile in the plug-in block or a coding tab in the box header. Doing this will reduce the likelihood of any mix-ups. A suitable procedure for coding can befound in appendix A.2.

2.2.1 Mechanically coding the connection block

WarningAn incorrect assignment of connection blocks and I/Omodules when conducting installation and maintenancework can cause severe damage during operation.

� To avoid incorrect assignment, pay attention to the correct mechanical coding of the connection blocks whenmounting.

Faulty mechanical coding will result in the certification becoming invalid.

Connection blocks and CPX-P modules are equipped with amechanical coding system. The coding system allows connection blocks to be mechanically coded, thereby preventing amodule from being inserted into a different product versionduring subsequent maintenance work (for intrinsically safeand non-intrinsically safe wiring) or into a foreign moduletype.

The top of each CPX-P type electronics module is providedwith a fixed coding pin. The configuration and shape of thecoding pin depend on the module type and product version.

3.2 Installation

Recommendation: When dealing with tension spring andscrew terminal connections, utilise the mechanical codingoption in order to avoid connection errors during subsequentinstallation work (� Fig. 1/6 and appendix A.2).

3.2.1 Setting the miniature switch

The function range and the address space (process image) ofthe module can be extended via miniature switches. An extended function range also allows channels 0 ... 3 to be usedas counter inputs or for frequency monitoring.

With an extended function range the module provides currentcounter readings and frequency measurements in the process image inputs (PII). 8 additional bytes are therefore allocated in the PII. 1 additional byte is also allocated in the PIO.Furthermore, parameterisation options are also available forthe extended functions.

3. Installation


Inputs 4 ... 7 can be used exclusively as digital inputs. Inputs0 ... 3 also support the counter and frequency measurementoperating modes, whereby only input 0 supports the frequency measurement up to 10 kHz (� operating mode Din Tab. 3/8).

Configuration of process image inputs (PII)

Byte 0 in PII For inputs that are configured as a digital input, the signalstates (0/1) of the digitised input signals are represented inbyte 0.For inputs that operate in the counter or frequency measurement operating mode, the alarm signals (e.g. limit valuereached or limit value fallen below/exceeded) are represented in byte 0 (� Tab. 3/9).

In the event of a short circuit or wire break the parameterisedreplacement value is issued (� Tab. 3/28 and Tab. 3/29).

Byte 1 in PII The module represents the diagnostic status of the 8 inputchannels in byte 1 of the PII (� Tab. 3/9). A 1-signal indicates that there is a channel error at the corresponding input(short circuit, wire break). In the “Counter” operating modea 1-signal also indicates an undervoltage has been detectedthat is less than or equal to 20ms. Retraction of the diagnostics function is only possible by re-parameterisation orresetting the respective counter. The user should ensurehere that the validity of the counter value is checked andevaluated.

A 0-signal indicates that the input signal is in a signal rangethat is permissible for Namur sensors.

Byte 2 to 9 in PII If the miniature switch of the module is set to ON, bytes 2 to9 in the PII depict the current counter readings or frequencymeasurements. Two bytes are occupied in the PII for eachcounter or frequency measurement (� Tab. 3/9).

3. Installation


During configuration these two bytes (low byte, high byte)must be consolidated into one word (16 bit) in the controlsystem. The low byte and high byte location is to be arrangedin a different manner for various control systems.

Some CPX bus nodes provide a parameter which allows theprocess value display for analogue values to be set globally(� bus node description, parameter analogue process valuedisplay).

� Set the parameter according to the mode of operation ofthe control system used (� bus node description).

3. Installation


3.3.3 Selecting the operating mode

If the miniature switch (� section 3.2.1) of the module is setto OFF, the module makes all 8 channels available as digitalinputs according to EN 60947-5-6 (operating mode A).

If the miniature switch is set to ON, the desired operatingmode must be activated for input channels 0 ... 3 by means ofparameterisation (� Tab. 3/20).

Input channels 4 ... 7 can be used exclusively as digital inputs- independent of the setting of the miniature switch.

3.3.4 Operating mode A - digital input

Certain parameter alterations cause an initialisation of therespective channel. (� section 3.3.8).

In the digital input operating mode the applied signal is converted into a digital signal (0/1) in accordance with specification EN 60947-5-6 (Namur) and stored in the correspondingbit in byte 0 of the PII. If an error occurs (e.g. short circuit,overload, wire break, etc.), the last correct value or the parameterised replacement value is valid depending on parameterisation (Tab. 3/28 and Tab. 3/29).

A signal extension time (� Tab. 3/24 and Tab. 3/25) and aninput debounce time (� Tab. 3/26 and Tab. 3/27) can beactivated by means of parameterisation.

Detailed information regarding the signal extension time andinput debounce time parameters can be found in the CPXsystem description. In the CPX-P-8DE-N-..., however, theseparameters are channel-specific and influence the behaviourof an individual channel.

3. Installation


3.3.5 Operating mode B - Counter

The counters count rising or falling edges of the digitisedinput signal upwards or downwards depending onparameterisation.

Certain parameter alterations cause an initialisation of therespective channel. Counters are thereby reset to the startingvalue (lower or upper limit value) (� section 3.3.8).

time limits the max. counting rate. At a debounce time of 3 ms, forexample, this is approx. 166 Hz.

Tab. 3/11: Counter properties (operating mode B)

The “Counter input” operating mode is specified via the parameter “Operating mode of the input channel” (� Tab. 3/20).The counter is controlled (start, stop, reset) via the processimage outputs (� Tab. 3/10).

3. Installation


The limit values of the counter are freely specified within therange of values by means of parameterisation (� Tab. 3/32and Tab. 3/33). The corresponding bit in byte 0 of the PII supplies the alarm signal (limit value reached/not reached). Thecurrent counter setting is shown in the PII (byte 2 ... 9)(� section 3.2.1).

Counter inputs can be configured as incremental or decremental counters by using the counter configuration parameter. In addition, the edge polarity can also be specified(� Tab. 3/30).

Incremental counters Incremental counters count upwards starting from the parameterised lower limit value to the upper end of the countingrange (32767).

Upon reaching the parameterised upper limit value, the bitassigned to the relevant channel is set in byte 0 of the PII.Upon reaching the counting range limit the counter isstopped (maximum value = stop value).

3.3.6 Operating mode C, D - frequency measurement

In the frequency measurement procedure rising edges of thedigitised signal are counted within a parameterised gate timeand the frequency subsequently calculated (f = n/t). If thevalue exceeds or falls below the specified limit values, the bitassigned to the relevant channel is set in byte 0 of the PII(� Tab. 3/9).

Certain parameter alterations cause an initialisation of therespective channel. This stops the current frequency measurement (� section 3.3.8).

signal are counted. The debounce time limits the max. measurable frequency. At a debounce time of 3 ms, for example, this isapprox. 166 Hz.

Tab. 3/15: Frequency measurement (operating mode Cand D)

3. Installation


The “Frequency measurement” operating mode is specifiedvia the parameter “Operating mode of the input channel”(� Tab. 3/20). The frequency measurement can be switchedon and off via the process image outputs (� Tab. 3/10).

The frequency measured in the last gate period is shown inthe PII (byte 2 ... 9). An update is always effected at the endof the respective gate period. The length of the gate timethereby determines the resolution accuracy of the frequencymeasurement and the speed at which the measured value isupdated (� Tab. 3/31). For information regarding measurement accuracy � Technical data.

The corresponding bit in byte 0 of the PII supplies the alarmsignal (frequency in the permissible range or limit value notreached/exceeded).

Hysteresis for alarms: To prevent the alarm bit from being accidentally switchedback and forth, the bit is only reset again if a difference of atleast 2 signal edges has been determined in the followingmeasurement. At a gate time of 10 ms, for example, this corresponds to a difference of 200 Hz (a difference of 2 signaledges within the gate time of 10 ms).

The following applies for the limit values:

– Lower limit value (LLV) < upper limit value (ULV)

3.3.8 Instructions for avoiding parameterisation faults

NotePlease note that changes to certain parameters may inadvertently have an impact on signal, function and diagnosticstates.

An alteration of certain parameters causes a reinitialisation ofthe respective channel (� Tab. 3/18). Signal states cannotbe meaningfully evaluated in the PII of the respective channelduring the initialisation phase!

The initialisation of a channel results in the following:

– The signal bits for limit monitoring (� byte 0, PII), thedebounce time and the signal extension time of the channel are reset.

– The following applies if the channel operates in the frequency measurement mode or in the counter mode:

– Counters are set to the relevant limit value (incremental counters at the lower limit, decremental counters atthe upper limit)

– Frequency readings are reset.

When used in combination with the counter mode and thefrequency measurement mode, the function should bestopped before parameterisation by resetting the respectivestart/stop bits in the PIO. Doing this prevents undefinedstates during the parameterisation process.

3. Installation


Conduct the parameterisation process in the following sequence:

1. Stop the counter and frequency measurement via PIO

2. Conduct the parameterisation process. The channel isinitialised automatically.

3. If an error is not reported, the respective function can beused with the loaded parameters (start, stop and, if necessary, reset).

In the event of invalid parameters, the previously correctvalues remain effective.

The respective errors are registered or the message is suppressed depending on parameterisation of the module. Iftransmitted to the bus nodes, errors can be evaluated byhigher-level systems - depending on the bus protocol used.

The wire break monitoring and limit value monitoring functions are inactive by default.

By using the module parameter “replacement value”, you canspecify whether the replacement value or the last signalstatus is to be valid in a diagnostic case (� Tab. 3/28).

3.4.7 Diagnosis via the fieldbus or a network

Depending on parameterisation, CPX-EA modules register the

specific errors via the fieldbus or their network.

These can be evaluated via the:

– Status bits (system status)

– I/O diagnostic interface (system diagnosis)

– Module diagnosis

– Error numbers.

Further information on diagnosis can be found in the CPXsystem manual or in the manual for the bus node.

A.2 Coding proposal for terminal connection of the CPX-P modules

In order to ensure maximum protection against incorrect connection, all of the contact points for a connection areprovided with a coding element for the following proposedcoding procedure. Either a coding profile is to be insertedinto the plug-in block or a coding tab is to be inserted intothe recess of the box header on the connection block for eachcontact (� also Fig. 1/6).

4 coding tabs are used for the box header on the connectionblock and 4 coding profiles are used for the associated plug-in terminal block for the 8-pin terminal connections. This ensures up to 70 different codes are available.

The following table shows the codes for the box headers andthe code for the associated plug-in terminal block alongside.

A contact point designated “1” should be equipped with therespective coding element, a contact point designated “0”should not. In a modular system with up to 18 plug-in terminal blocks (max. 9 CPX-P modules permissible), a maximum of72 coding profiles are required for plug-in terminal blocksand 72 coding tabs are required for box headers.
