1.1 Structure of CP systems
Festo can assist you in solving your automation tasksat the machine level by means of valve terminals. Dueto their modular structure, valve terminals and I/Omodules from Festo can be incorporated to the bestadvantage in your machines and systems.

1. System overview
CP... 9609 1-3
The CP system consists of individual modules whichare connected by means of the CP cable. This permitsa decentralized arrangement of the CP system. Thecompact CP valve terminals can be mounted very closeto the cylinders which are to be actuated, thereby enab-ling short compressed air tubing to be used.
Short compressed air tubing minimizes the loss of airflow and the times required for pressurizing and ex-hausting the tubing.
This permits the use of smaller valves with sufficientflow and thereby helps to reduce costs.

1.1.1 CP system module functions
CP systems consists of the following modules:
CP module Function
CP node There are special CP fieldbus nodes for thevarious fieldbuses.– They provide the connection to certain
fieldbuses– They offer connections for up to 4 strings
to which I/O modules and valve terminals can be connected
– They transmit control signals to theconnected modules and monitor their functioning
CP valveterminals
– These provide various valve functions via valve plates for controlling pneumatic actuators
– Relay plates, pressure isolating plates andblanking plates can be used here as well
Input modules There are various special designs for various types of connections.– These provide inputs for connecting
sensors and permit e.g. the scanning of cylinder positions
Output modules – These provide universally usuable electrical outputs for actuating low current consuming devices (further valves,bulbs etc.)
1. System overview
CP... 9609 1-5
Depending on type, the CP nodes control the transferof data to a wide variety of control systems via thevarious fieldbuses. Some nodes have an integratedPLC. This enables the CP system to be operated au-tonomously without being coupled to a fieldbus.

1.3.1 Basic rules of addressing
– A CP node provides four strings with a total of 64input addresses and 64 output addresses.
CP node
– A string occupies 16 input addresses and 16 outputaddresses.
– The addresses are assigned fixed to the individualstrings and in ascending order.
Stringnumber
Input addresses(E = Input)
Output addresses(A = Output)
0 E0 ... E15 A0 ... A15
1 E16 ... E31 A16 ... A31
2 E32 ... E47 A32 ... A47
3 E48 ... E63 A48 ... A63
– The assignment of addresses to the individual mo-dules is therefore determined by the string to whichthey are connected.
– The addresses of an unoccupied string at the end ofthe complete address range can be used by otherfieldbus nodes, providing this supports the fieldbusprotocol used. Other unused addresses remainreserved for later extensions to the CP system.
1. System overview
CP... 9609 1-13
– A CP valve terminal always occupies 16 output ad-dresses, irrespective of how many valve solenoidcoils are fitted on it. Therefore only one valve termi-nal can be connected to each string. This enablesthe valve terminal to be extended at a later stagewithout the need for the address range to be shifted.

– A valve location always occupies 2 addresses evenwhen it is fitted with a blanking plate or pressure iso-lating plate. If a valve location is fitted with a doublesolenoid valve, the following assignment applies:- pilot solenoid 14 occupies the lower value address,- pilot solenoid 12 occupies the higher value address.With single solenoid valves, the higher value addressremains unused.
– Altogether, a maximum of 64 valve solenoid coils canbe addressed per node.

1.3.2 Address assignment after extension or conversion
WARNINGPlease take care when modifying the string assign-ment of your CP system. The input and output addresses for the modules willchange if you connect the modules to a differentstring.
A special feature of the CP system is its flexibility. If thedemands placed on the machine change, you can eas-ily replace or remove modules or add further modules.
The input and output addresses of already used mo-dules will not then change, providing they remain con-nected to the same string.
The following diagram shows as an example the newaddress assignment after modification of the string as-signment in Fig. 1/9.

In contrast to Fig. 1/9, string 0 and string 2 have beenextended by the addition of extra modules. On string 0,a CP valve terminal with 4 valve locations has beenreplaced by a valve terminal with 8 valve locations.Please note that the assignment of the input and outputaddresses on strings 1 and 3 has not changed.

3.1.2 Selecting the power unit
WARNINGAn isolating transformer as per EN 60742 (IEC 742,DIN/VDE 0551) with at least 4 kV isolation resist-ance is required for reliable electrical isolation of theoperating voltages.
The current consumption of a CP system depends onthe number and type of components connected.
Recommendation.
• Use a closed-loop power unit.
• When selecting the power unit, check that it has suf-ficient output. Calculate the total current consumptionaccording to the following table.
• Connect the operating voltage for the valve coils(pin 2) via EMERGENCY STOP.
The following table shows how to calculate the com-plete current consumption for a CP system. The valuesspecified have been rounded up. Please refer to theappropriate technical specifications for the current con-sumption of the valves and modules.

3.1.3 Configuring the CP system
CP systems can be coupled to various fieldbuses. Thecoupling is made via the CP node which has beenadapted to suit the appropriate fieldbus. CP nodesusually support various fieldbus protocols and baudrates for the appropriate fieldbus. The various settingsmust be made with the DIL switch on the node.
The following settings are possible depending on theCP node used :
Settingson the
node
– Fieldbus baud rate
– Fieldbus address
– Valve terminal test
On the compact design nodes, the DIL switches are si-tuated behind an easily accessible cover; on nodes instandard design, you must open the housing in order toset the DIL switch.
Information on the procedure as well as on the settingpossibilities can be found in the manual "CP fieldbusnode".

3.2.1 Connecting the CP modules
WARNING• Use the special CP cable (type KVI-CP-1-...) from
Festo for connecting the CP modules to a string.• Please note that the total length of the cable must
not exceed 10 m.
You thereby avoid:
– errors in data exchange between the node and theconnected CP modules.
There are four CP connections on the node for strings0...3. Modules with a total of 16 inputs and 16 outputscan be connected to each CP connection.
CPconnections
If required, a maximum of one module with outputs (val-ve terminal or output module) can be connected to theCP connections. These modules have a CP connectingsocket for coupling to an input module.
Input modules can also be connected directly to the CPconnecting socket of the node. The output addressesoccupied by this string then remain unused.

4.2 Preparing the CP system for commissioning
WARNINGLeave the fieldbus unconnected while you are com-missioning the CP system.
You thereby avoid:
– addressing errors which arise due to modification ofthe address ranges with various fieldbus systemswhile they are operating.
Before commissioning a fieldbus system with CP node,you should first prepare each individual CP system forcommissioning.
Prepara-tions
Proceed as follows:
1. Check the pneumatic tubing of the CP valve termi-nals with the aid of the manual override (see pneu-matics manual).
2. Check the complete electrical circuitry of the CPsystem.
3. Save the current string assignment of the CP sys-tem as the nominal assignment, as described in thefollowing section.
4. Commissioning
4-4 CP... 9604
4.2.1 Saving the string assignment
WARNINGIf you later modify the string assignment of your CPsystem:• Check the address assignment of your CP system
after saving the string assignment and beforestarting any user programs.
You thereby avoid:
– addressing errors with incorrectly installed CP mo-dules.
Each string, and therefore each module connected to astring, is assigned a fixed address range (see chapter1). The assignment of strings and modules, accomplis-hed with CP cables, is known as the string assignment.
Stringassignment
In order to prepare for commissioning, you must createand save the desired string assignment. The appropri-ate addresses are then assigned to the connected CPmodules.
Saving the string
assignment
PLEASE NOTENon-assigned strings are saved as string assign-ments at the factory.
4. Commissioning
CP... 9604 4-5
Save the string assignment as follows:
1. Check that the CP modules are connected to thestring which provides the intended address range(see also chapter 1).
2. Check also that the modules are correctly markedand that the CP cables are correctly fastened withthe union nut.
3. Now switch on the operating voltage.The status LEDs on the CP modules and the LEDson the strings to which CP modules are connected,or where the string assignment has been modified,will now flash.
4. Now take a pen or other pointed object and pressthe SAVE button on the fieldbus node. The current string assignment will then be saved asthe nominal assignment and the appropriate ad-dresses assigned to the CP modules.
5. Check to see that the status LEDs on the moduleslight up and that the string LEDs on the node areout (see also section 4.5).If this is the case, all the CP modules are ready tooperate and the saved string assignment is identicalto the current string assignment.
4. Commissioning
4-6 CP... 9604
With the aid of the saved string assignment, the CPnode helps to avoid connecting errors and therefore ad-dressing errors. It checks automatically whether thecurrent string assignment corresponds to the savedstring assignment. A distinction is made here betweenthe following test phases:
Test phases
– test during the power-up phase (see section 4.3)
– test during operation (see section 4.4).
If the status LEDs on all the modules light up, the CPsystem is prepared for commissioning. Now you cancommission the CP system on the fieldbus. Differentprocedures are necessary for commissioning thevarious fieldbus systems. Explanations on this can befound in the manual for the CP fieldbus node.
4. Commissioning
CP... 9604 4-7
4.3 Reaction of the CP system when switched on
When the voltage supply is switched on, the node as-certains the current string assignment automatically. Itascertains, one after the other, which CP modules areconnected to which strings.
If the current assignment corresponds to the saved as-signment, the fieldbus node will switch immediately toready status. The status LEDs on the modules will thenlight up, thereby indicating readiness to operate (seeFig. 4/2).
If the current assignment does not correspond to thesaved assignment, the LED of the relevant string willflash on the fieldbus node. The status LEDs on the mo-dules will also flash. In this case, the CP system is notready to operate.
PLEASE NOTEIf several strings do not match, their string LEDs willflash one after the other.
4. Commissioning
4-8 CP... 9604
The ready status can be restored in one of the followingways:
– by eliminating assignment errors manually
– by saving the current assignment as the nominal as-signment (see section 4.2.1).
Eliminating assignment errors manually
• Restore the saved assignment by connecting thenode with the appropriate modules again.
If the current assignment is now correct again, the CPnode will switch automatically and immediately to readystatus.
4. Commissioning
CP... 9604 4-9
1) Due to saving the string assignment, the scope of data for fieldbus communicationmay also be changed.
2) If the address range is saved by saving the string assignment when the power supplyis switched on, it may be necessary to switch on the power supply again(see manual "CP node").

Replacing modules during operation
WARNING• Check whether the organisational concept of your
machine/system permits the replacement of modules during operation.
• Make sure that modules are not separated from astring and then connected to another string duringoperation. Use the labels (type IBS 6x10), to markmodules unambiguously.
You thereby avoid:
– an incorrect string assignment ascertained by thenode and then displayed when the operating voltageis switched back on.
4. Commissioning
CP... 9604 4-13
Please observe the following rules:
Only modules of the same type can be replaced duringoperation.
Basic rules
• Replace I-module by I-module of same type(replacement of CP-E16-M8 by CP-E16-M12x2is not permitted during operation)
• Replace O-module by O-module
• Replace valve terminal by valve terminal of the sametype (valve type and number of valves must corre-spond).
Replacement by another module type (e.g. O-moduleby valve terminal) will be interpreted by the node as auser error.
In this case therefore, the ready status will not be re-stored to the relevant module during operation.
During operation, a maximum of one I-module and onemodule with outputs (O-module or valve terminal) maybe separated from the CP system or replaced at thesame time, e.g.:
Replacementpossibilities
• one I-module and one valve terminal or
• one I-module and one O-module.
4. Commissioning
4-14 CP... 9604
If more than the above-mentioned modules are separ-ated from and then connected again to the CP systemsimultaneously, there is a danger of a connection error(reversal of module connections). Operation of thesemodules is not, therefore, resumed while the system isoperating.
In this case, the operating voltage must be switched onagain. The test will now run through the power-upphase and assignment errors will be displayed accord-ingly. Proceed as follows when replacing a module:
1. With output modules and valve terminals:Switch off:- the compressed air supply to the valve terminal- the operating voltage supply to the O-module.
2. Loosen all connecting cables and, if necessary, all tubing.
3. Connect all the cables and, where appropriate, tubing with the same type of new module.
4. With output modules and valve terminals:Switch on the operating voltage supply and the compressed air supply again.
5. Now reconnect the same type of new module to the same string.

Correct the string assignment as follows:
•• Use the string LEDs to ascertain on which stringsthere is an assignment error.
•• Check whether the correct modules or module typesare connected to these strings.
•• Replace defective modules or defective CP cables.
If the node ascertains an incorrect string assignmentduring the power-up phase, the status LEDs of all theconnected modules will flash. Modules of which thestatus LED does not flash, are not ready to operate.There is a non-permitted string assignment, forexample, or the connection to the node is interrupted.
•• In this case, create a permitted string assignment orcheck the connection to the node.

PLEASE NOTEThe following information is for the exclusive use ofpersonnel trained in electrical engineering who are al-ready familiar with the contents of the chapter "Instal-lation" in this manual.
A load-dependent drop in voltage occurs on all threecables for operating voltage supply to a node. This cancause the voltage at pin 1 or pin 2 of the operatingvoltage connection to be outside the permitted toleran-ce.
Recommendation
•• Avoid long distances between the power unit and thenode.
•• Calculate suitable cable lengths and cross sectionsin accordance with the following formulae.
PLEASE NOTEThe following formulae require that the cross sec-tions of the operating voltage cables (pins 1, 2 and3) are the same.
