1.5.2 Selecting the cable

· Calculate the necessary cross−sectional area and themaximum permitted cable length.

· Avoid long distances between the power unit and thevalve terminal. Long cables reduce the voltage supplied

by the power unit.

1.5.3 Selecting the power unit�

Warning· For the power supply use only PELV circuits as perIEC/DIN EN 60204−1 (Protective Extra−Low Voltage,PELV).Take into account also the general requirements forPELV circuits as per IEC/DIN EN 60204−1.

· Use only power packswhich guarantee reliable electricalisolation of the operating voltage as per IEC/DINEN�60204−1.

By the use of PELV power units, protection against electricshock (protection against direct and indirect contact) is guar�anteed in accordance with IEC/DIN EN 60204−1 (electricalequipment of machines, general requirements).

The current requirement of a CP system depends on thenumber of CP modules and valve coils. Recommendation:

· Use closed−loop controlled power units.

· When selecting the power unit, check that it provides

sufficient output. Calculate the total current requirementin accordance with section 1.5.1.

1. Installation


1.5.4 Connect the power supply of the valve terminal

Please noteUse only a socket in accordance with appendix A.2 for thepower supply and connect this only to the connection forthe power supply (see Fig.�1/1).

1. In order to open the plug, loosen the centre knurled nut.

2. Open the strain relief on the rear part of the housing.

Then pass the cable through.

3. Remove 5 mm of insulation from the end of the cable and

fit end sleeves on the strands.

4. Connect the ends of the conductors.

5. Replace the connector part on the housing of the socket.

Pull the cable back so that there are no loops inside thehousing.

6. Tighten the strain relief.

1. Installation


Observe the following when connecting the 24 V load voltage(pin�2):

· Observe the tolerance (20.4 ... 26.4 V DC). Check the 24 V load voltage of the valves while the

system is operating.

CautionExcessive voltages or short circuits can lead to functionaldamage to the CP...−SC−DP, whereby actuators can nolonger be controlled.

· Protect the load voltage of the valve coils with externalfuses.

In order to ascertain the size of the fuses, calculate firstthe maximum current consumption in accordance withsection 1.5.1.

Please noteCheck your emergency stop circuit, in order to ascertainthe measures necessary for switching your machine/sys�tem into a safe state in the event of an emergency stop.

� Switching off the load voltage for the valves and outputmodules in the secondary circuit of the power unit.

� Switching off the compressed air supply for the valveterminal.

Due to energy stored in the input circuitry of valve ter�minals, there may be a delayed reaction of the valves whenthe load voltage is switched off.

Take this into consideration, e.g. as follows:

� by using an input signal in the controller for checkingwhether the load voltage has been switched off.

� by blocking the control signal for the valves by lockingthe output signal with the input signal �Load voltage".

1. Installation


Potential equalization

Earth the valve terminal:

� at the power supply connection (pin 5)

� and at the earth connection of the housing (see Fig.�1/1).

Please note· By means of low−impedance connections, make surethat the housing of the valve terminal and the earthconnection at pin 5 have the same potential and thatthere are no equalizing currents.

In this way, you will avoid interference caused by electro�magnetic influences.

2.1 Preparing the valve terminal for commissioning

2.1.1 Switching on the operating voltages

Please notePlease observe the switching−on instructions in the manualfor your controller.

· Before switching on, make sure that the field bus hasbeen configured completely and correctly as specified.

Recommendation:Providing the safety concept of your machine/system permitsthis, commission the CP...−SC−DP at first with both supply volt�

ages (pins 1 and 2), but without compressed air. A suitabletest function is therefore available which does not triggerundesired reactions.

Please observe the following when switching on the powersupply:

Common supply Common power supply for the control system and all field

bus slaves via a central power unit or a central switch.

Separate supply If the control system and the field bus slaves have separate

power supplies, the devices must be switched on in thefollowing sequence:

1. the operating voltage supply for all field bus slaves

2. the operating voltage supply for the controller.

2. Commissioning


2.1.2 Address assignment � CPA−SC−DP

The CPA−SC−DP valve terminal always occupies 32 outputaddresses, irrespective of the number of valve solenoid coils

fitted. This enables the valve terminal to be extended at alater date without the need to shift the addresses.

Please noteAs the CPA−SC−DP always occupies 32 addresses, the nextfree address in the CP extension is 32.

� Depending on the configuration (number of valve loca�tions and internal cabling), a valve location supports thecontrol of one or two solenoid coils. Accordingly, the valvelocations occupy one or two addresses, irrespective ofwhether the valve location is fitted with a valve plate or ablanking plate. The internal circuitry cannot be modifiedat a later stage.

The following diagram shows how many solenoid coils can becontrolled on the individual valve locations.

Pos = number of the valve locationCoils = total number of valve solenoid coilslight grey = 1 valve coildark grey = 2 valve coils

� If a valve location for 2 addresses is actually equippedwith two solenoid coils, the following allocation applies:

� pilot solenoid coil 14 occupies the less significantaddress

� pilot solenoid coil 12 occupies the more significantaddress.

� If a valve location for two addresses is fitted with only onesolenoid coil, the more significant address will remainunused. However, the valve location still occupies twoaddresses.

� Address assignment of the valve coils on the CPA−SC−DP isfrom left to right and on the individual valve locationsfrom the front to the rear.

3.3 Diagnosis via PROFIBUS−DP

The CP...−SC−DP supports the following diagnostic possibilityvia PROFIBUS as per EN 50170:

� identification−related diagnosis (see section 3.3.4)� identification number.

� channel−related diagnosis (section 3.3.5)� module number and type � type of diagnosis (fault number).

Please noteIf you are operating the CP...−SC−DP with the tool changeconfiguration, only one diagnostic information will beoutput for the CP extension (see section 3.3.6).

Please noteThe diagnostic information is only sent to the mastersystem if the device−related diagnosis is activated in theswitch module. In order to do this, set switch element 2 ofthe DIL switch to �OFF".

3.3.7 Siemens SIMATIC S5/S7

With these controllers you have the possibility of specifyingthe reaction of the CP...−SC−DP to the faults named (detailssee controller manual).

Almost all configuration programs contain the function

�Response monitoring". For the operating modes named, thespecified time corresponds to the drop−out time of the valvesand electrical outputs.

Further details on response monitoring can be found in therelevant controller manuals.

3. Diagnosis


You can set two types of fault reactions of the control system:

� hard fault reaction: the controller switches to the operat�ing mode �STOP" when a fault occurs.

� soft fault reaction: the controller remains in the operatingmode �RUN" when a fault occurs.

B.1 PROFIBUS−DP: Commissioning with the general DP master

The CP...−SC can be controlled by any PLC, PC or industrial PCwith a PROFIBUS−DP module as per EN 50170.

Further information Read the information on the following themes in theappropriate sections:

� Module consistency, FREEZE and SYNC, identifiers:section 2.2.

� GSD: section 2.3

B.1.1 Bus start

In order to commission the CP...−SC correctly, the DP mastermust carry out the following functions in the sequence

specified:

1. request diagnosis

2. send parametrizing data (Set_Prm)

3. check configuration data (Chk_Cfg)

4. transfer input and output data (cyclic data exchange,Data_Exchange)

5. read diagnostic information (Slave_Diag).

The composition and contents of the individual telegrams aredescribed in the following sections.



B.1.2 Send parametriziung data

Tab.�B/3: Overview of DP identifiers for various extensions of the CP...−SC

Configuration examples can be found in section 2.5.



B.1.4 Transferring input and output data

Data_Exchange The cyclic exchange of data is accomplished with thefunction Data_Exchange.

With this function the output data for the CP...−SC is trans�

mitted as an octet string of length x. The octet string lengthdepends on the number of identifier bytes.

Please noteWith the function Data_Exchange, the CP...−SC expects theoutput data for the valves and electric outputs.

The input data are sent to the master as a reply telegram.

B.1.5 Read diagnostic information

Slave_Diag The diagnostic data are requested by the CP...−SC via thefunction Slave_Diag (see section 3.3, Diagnosis viaPROFIBUS−DP).

Set_Prm With the function Set_Prm you can determine the watchdogtime (WD_Fact_1, Octet 2, WD_Fact_2, Octet 3). In the eventof a fault, the CP...−SC will switch off all the valves and elec�tric outputs after the parametrized time (e.�g. if there is abus failure).

B.1.8 Transmission times on the PROFIBUS−DP

Please noteObserve here the cycle time of your PLC and the updatetime of the PROFIBUS−DP.

The time delay within the CP...−SC depends on the amount of

data and therefore on the extension of the CP...−SC. It amounts to: < 2 ms.

Please refer to the manual for your controller for ascertainingthe total time required for transmission.
