1.1 Structure of the CPX terminal

CPX terminals consist of electric and pneumatic modules forcontrolling pneumatic actuators and low−current consumingelectric devices (further valves, bulbs, etc.). They are usuallyplaced decentrally directly on the machine or system.

Design variants CPX terminals are available in plastic version (type CPX−...)and in metal version (type CPX−M−...) with various differentfunctions. They can be fitted with different electric and pneu�matic modules (valves) in accordance with the customer’swishes. The equipment fitted on the CPX terminal in this man�ual may therefore differ from the equipment you are using.

Tab.�1/3: Valve terminal pneumatics for CPX terminals

The electric and pneumatic side of the CPX terminal can beadapted to various requirements. The electric side can befitted with various electric CPX modules, e.g.�a CPX bus node,digital and analogue CPX I/O modules etc. (see Tab.�1/1).



The pneumatic side can be fitted with pneumatics of typeMPA, VTSA, Midi/Maxi or CPA (see Tab.�1/3). Different sizes of valves are possible here. Pneumatic modules are not abso�lutely necessary. CPX terminals can consist exclusively ofelectric modules. If pneumatic modules are to be used, thepneumatic interface appropriate to the pneumatics in ques�tion is required (see Tab.�1/2).

CPX bus node

The node point of a CPX terminal with fieldbus connection isthe CPX bus node, which controls the following functions:

� The connection of the terminal to the relevant field bus

� The control of data transfer to/from the field bus moduleof your control system

� Read and write access (depending on the CPX bus node)to system−relevant parameters and diagnostic data (access to internal data and parameters)

� Internal control of the terminal

CPX bus nodes provide the connection to certain fieldbuses,pass control signals on to the other CPX modules and monitortheir ability to function. Basic settings for fieldbus communi�cation can usually be made by DIL switch directly on the CPXbus node.

Detailed information on the CPX bus node you are using can befound in the manual for the relevant CPX bus node.

CPX Front End Controller (CPX−FEC)

The CPX Front End Controller can be used together with a CPXbus node or independently of a CPX bus node. It offers thefollowing functions, for example:

� Independent control of the CPX valve terminal (StandAlone)

� Communication via Ethernet (e.g. web server, e−mail,EasyIP)

� Ethernet slave function (via Modbus TCP)

� Communication via fieldbus (only in conjunction with theappropriate CPX bus node)



CPX I/O modules

Processing signals can be evaluated with the CPX I/O mod�ules. Input modules provide inputs for connecting sensorsand enable cylinder positions to be scanned, for example.Output modules provide universally usable electric outputsfor controlling low−current consuming devices (further valves,bulbs, etc.).

NoteIncluding the CPX bus node, a maximum of�10 electric CPXmodules plus a pneumatic interface are permitted on theelectric side.

The CPX I/O modules have various types of connections. Theconnections are on a sub−base which can be removed fromthe module. This offers the following advantages:

� The CPX terminal can be fitted with the desired con�nections. It can be adapted easily to various applica�tions and operating conditions.

� When servicing is required, the electronics of the I/Omodules can be replaced without the need to dis�mantle the CPX terminal, or to loosen individual con�nections on the I/O modules.

The following types of connection can be used:

� M12 connection, 5− or 8−pin

� M8 connection, 3− or 4−pin

� Terminal strips, 16−pin

� Sub−D connection, 25−pin

� HARAX connection, 4−pin

Further information on the CPX I/O modules can be found in themanual �CPX I/O modules", type P. BE−CPX−EA−...



CPX−CP interface

The CPX−CP interface serves for connecting decentrally ar�ranged CP modules (CP valve terminals and CP I/O modules).It transmits control signals to the connected CP modules andmonitors their ability to function. Maximum 128 external I/Osare possible per CPX−CP interface.

Detailed information on the CPX−CP interface can be found inthe manual for the CPX−CP interface type P. BE−CPX−CP−...

Pneumatic interface

If the CPX terminal is to be fitted with valves, a pneumaticinterface will be required (see Tab.�1/2). The pneumatic inter�face is the interface between the electric and pneumatic pe�ripherals. It forms the mechanical connection between thepneumatic and electric modules and transmits the electricsignals.

The CPX pneumatic interface is mounted on the right−handside of the last electric module. Pneumatic interfaces can beused for e.g.:

� Pneumatics of type MPA (maximum 128�solenoid coils)

� Pneumatics of type VTSA (maximum 32�solenoid coils)

� Pneumatics of type Midi/Maxi (maximum 26�solenoidcoils)

� Pneumatics of type CPA (maximum 22�solenoid coils)



Pneumatic interface forMPA pneumatics

The pneumatic interface for MPA pneumatics provides themechanical and electrical connection to the MPA pneumaticmodules. Therefore, from the point of view of the CPX termi�nal, the MPA pneumatic interface does not count as an elec�tric module. Instead, the individual MPA pneumatic moduleseach represent an electric module with digital outputs fortriggering the integrated valves.

Pneumatic interfaces forVTSA pneumatics, Midi/Maxi pneumatics or CPA pneumatics

From a technical point of view, the pneumatic interfaces for VTSA pneumatics, Midi/Maxi pneumatics or CPA pneu�matics represent electrical modules with a variable (configu�rable) number of digital outputs for activating the integratedvalves.

Detailed information on the CPX pneumatic interfaces andMPA pneumatic modules can be found in the manual for theCPX I/O modules of type P. BE−CPX−EA−...

Valve terminal pneumatics

The valve terminal pneumatics provide the following:

� Common channels for supply and exhaust air

� Electric signals for all valve solenoid coils

Working lines 2 and 4 are provided for each valve position onthe individual pneumatic modules. The valves are suppliedwith compressed air via the common channels or via specialsupply modules. Both the air and auxiliary pilot air from thevalves are also exhausted via these common channels.Further modules for pressure supply are also available, e.g. in order to permit work to be carried out with differentwork pressures.



CPX terminals without pneumatics

CPX terminals without pneumatic modules possess an endplate instead of the pneumatic interface. This design providesdigital and analogue inputs and outputs on the relevant fieldbus. A maximum of 10 electric modules (including theCPX bus node) are permitted on a CPX terminal.

Valve terminal pneumatics of type MPA

MPA pneumatics consist of serially linked MPA pneumaticmodules. From a technical viewpoint, the MPA pneumaticmodules in a CPX terminal represent digital output modulesfor controlling the integrated valves (valve solenoid coils). The pneumatic interface for MPA pneumatics provides themechanical and electrical connection to the MPA pneumaticmodules.

CPX terminals with MPA pneumatics can be expanded as fol�lows:

1.1.2 Structure of the electric CPX modules

An electric CPX module always consists of:

� An interlinking block (see section�1.1.3 for variants)

� An electronics module

� A connection block (selectable for I/O modules)

1 Sub−base (selectable housing upperpart)

2 Electronics module

3 Interlinking block (selectable housinglower part)

Fig.�1/8: Structure of the CPX modules (example)

Connection block The upper part of the housing selected for the CPX I/O mod�ules is called the connection block. Connection blocks providethe necessary connections for sensors and actuators. In thisway, the CPX terminal offers a high degree of flexibility withregard to adaptation to different applications and operatingconditions.



Electronic module The electronic module contains the electronic components.It�is connected to the interlinking block and to the connectionblock by means of electric plug connectors. Many electronicsmodules can be combined with various connection blocks.

In the case of the CPX bus node, the connection technology isan integral part of the module; in other words, the connectionblock and the electronics module form a single unit.

Interlinking block The lower part of the housing of the electric modules is calledthe interlinking block. Interlinking blocks serve for the electri�cal and mechanical linking of the modules. They can providea�connection for supplying the operating voltage and/or loadvoltage and transmit the operating and load voltages to theneighbouring modules (see section�1.1.3). In the plastic ver�sion of the interlinking blocks, the mechanical link betweenthe electric modules is made via tie rods (see section�2.2.1).Interlinking blocks in the metal version are bolted togetherindividually (see section�2.3).

You can replace electronics modules with connection blocksduring servicing without the need to dismantle the CPX ter�minal or loosen individual connections. Instead the entireconnection block is removed, the electronics module is re�placed and the connection block is placed into position again(see manual for the �CPX I/O modules", type P. BE−CPX−EA−...).



NoteWith a combination of connection blocks and interlinkingblocks with metal on plastic or plastic on metal, always usethe appropriate screws for the interlinking block (seewww.festo.com\catalogue):

� With plastic interlinking block: thread−cutting screws

� With metal interlinking blocks: screws with metric thread

1.1.3 The power supply concept of the CPX terminal

The operating and load voltages for the CPX terminal are sup�plied via the interlinking blocks (see Tab.�1/5 and Tab.�1/6).These conduct the operating and load voltages to the neigh�bouring modules.

Interlinking blocks are available in various housing designsand with alternative connections:

Intermediate supply forload voltage supply of valves in MPA

When using MPA pneumatics, a max. of�8 sub−bases equipped with valves can be supplied electrically with load voltage by the CPX terminal. If the pneumatics side is expanded further (>�8�sub−bases), an electric supply platemust be used for the power supply.

For additional information about permissible power supplies,see the relevant manual for �MPA−... pneumatics", type P.BE−MPA−... in the section �Replacing electronics modules".



1.2 Commissioning, diagnosis and operational functions

The system reaction of the CPX terminal can be adapted tothe relevant application. For this purpose, the CPX terminalprovides extensive functions for commissioning, diagnosisand operation.

Commissioning and operational functions

The reaction of the CPX terminal can be adapted to individualrequirements by parameterising. The following reactions ofthe CPX terminal can be influenced, for example, by accessingthe internal parameters:

� The reaction of the outputs and valves to fieldbus com�munication faults (fail−safe settings)

� The reaction to fault elimination

� The debounce times for digital input signals

� The signal extension for digital input signals

� The force settings (force signal status)

� The operating method of the diagnostic memory

The CPX terminal is supplied from the factory with presetparameters.

CautionA different parametrisation will result in different characte�ristics. Check especially when replacing CPX terminals tosee which settings are necessary and make sure that theseare restored (e.g. in the start−up phase by the higher−orderPLC/IPC).



Information about the module−specific parameters supportedby the module you use can be found in the manual for therelevant module. Basic information on the different para�meters can be found in Appendix C in this manual.

Diagnostic functions

Extensive diagnostic information can be accessed dependingon the fieldbus used.

Status bits Common diagnostic messages (global error messages) aredisplayed by means of 8 internal inputs (8 status bits).

I/O diagnostic interface With fieldbuses that do not possess extensive diagnosticfunctions, the diagnostic information of the CPX terminals isavailable via the I/O diagnostic interface. The I/O diagnosticinterface enables bus−independent access to diagnostic in�formation, data and parameters via internal digital I/Os(16�inputs and 16 outputs).

Diagnostic memory Faults that occur during operation are entered in a diagnosticmemory. The first or the last 40 entries are saved, as well asthe relevant time measured from the moment the power sup�ply was switched on.

Fieldbus−specific diagnos�tic functions

Special diagnostic functions or communication services areavailable, depending on the fieldbus used. For examplecommunication services on:

� DPV1 (PROFIBUS)

� The PCP channel (Interbus)

� SDO access (CANopen)

� etc.

2.1 General instructions on assembly and dismantling

WarningUncontrolled movements of the connected actuators anduncontrolled movements of loose tubing can cause injuryto human beings or damage to property.

Before carrying out assembly and maintenance work,switch off the following:

� Compressed air supply

� The operating and load voltage supplies.

NoteHandle all modules and components of the CPX terminalwith great care. Note especially the following:

� Screw connections must be fitted without distortion andmechanical tension. Screws must be fitted accurately(otherwise threads will be damaged).

� The specified torques must be observed.

� The modules must not be offset (IP 65).

� Contact surfaces must be clean (avoid leakage and con�tact faults).

� The contacts of the midi/maxi valve solenoid coils mustnot be bent (not resistant to bending, i.e. they will breakoff if they are bent back).

� Electrostatically sensitive devices.Do not touch the contact surfaces of the plug connectorson the modules and components.

2. Assembly


Rules for assembly

� Including the CPX bus node, a maximum of 10 electricmodules plus a pneumatic interface are permitted on theelectric side.

� For MPA pneumatics:The MPA pneumatic interface does not count as an elec�tric module. Instead, the individual MPA pneumatic mod�ules each represent an electric module with digital out�puts for triggering the integrated valves. A maximum of16�MPA pneumatic modules are permissible. If there aremore than 8�modules, an additional load voltage powersupply is needed for the valves.

� Except for the pneumatic interface, each electric moduleincluding the CPX bus node can be fitted in any positionon the electrical side.

The electric modules can be arranged in any sequence in theCPX terminal. Depending on the fieldbus protocol used, itmay however be sensible to arrange modules of the sametype one after the other. In these cases, the address assign�ment and therefore communication between the fieldbusmaster and the individual CPX terminals can be optimised.

� The pneumatic interface must be placed on the right−handside as the last electric module.

� Interlinking blocks can be used universally for CPX busnodes and I/O modules.

� If interlinking blocks with additional supply are not re�quired, the interlinking block with the system supply canbe fitted in any desired position.

� If interlinking blocks with additional supply are required,these must always be placed to the right of the systemsupply (see also section 1.1.3).

� Connection blocks can be used universally for differentI/O modules.

2. Assembly


� The maximum number of pneumatic components sup�ported is as follows:

� 128�valve solenoid coils of type MPA (16�MPA pneu�matic modules with max.�8�valve solenoid coils each)

� 32�valve solenoid coils of type VTSA/VTSA−F

� 26�valve solenoid coils of type Midi/Maxi

� 22�valve solenoid coils of type CPA

2.2 Assembling electric modules with plastic interlinking blocks

CautionInappropriate handling can result in damage to the mod�ules.

· Observe the handling specifications for electrostaticallysensitive devices.

· Discharge yourself before installing or removing sub−assemblies to protect the sub−assemblies from staticdischarges.

You can adapt the CPX terminal to your requirements by ad�ding or removing modules. The mechanical link between theelectric modules is made via tie rods in the interlinkingblocks. The length of the tie rod is determined by the possiblenumber of interlinking blocks or electric modules.

Dismantle the CPX terminal before you add or remove inter�linking blocks. If you are using the additional fastenings oftype CPX−BG−RW−... for fastening onto a wall, it may benecessary to loosen existing fastenings (see also Tab.�2/4).

2. Assembly


2.2.1 Replacing a complete module or interlinking block with tie rod inter�linking

Assembly To insert a module or interlinking block, proceed as follows:

1. Insert the module in the desired position (see Fig.�2/3).The tie rod must lie exactly over the tie rod groove.

CautionWhen interlinking blocks are arranged in series:Make sure that the electric plug connectors of the inter−linking blocks are not bent.

2. Align the CPX terminal on a flat surface so that the compo�nents are not offset. Use the bearing surface for the H−railto align the component correctly. It is easier to align if youuse an H−rail. Alternatively, you can place the CPX ter�minal without pneumatics or with the CPA pneumatics insuch a way that the interlinking blocks’ electrical connec�tions are facing upwards (see Fig.�2/4). The tie rod is heldin the tie rod groove by the force due to weight.

2.4 Fitting the CPX terminal

NoteFit the CPX terminal so that there is sufficient space forheat dissipation and ensure that the maximum limits fortemperatures are observed (see Technical data).

You can fit the CPX terminal in one of two ways:

Mounting method Description

H−rail mounting The CPX terminal is suitable for fitting onto an H−rail (mounting rail asper EN�60715). There is a guide groove on the back for hanging thevalve terminal onto the H−rail.

Wall mounting The end plates and the pneumatic interface contain holes for fittingthe terminal onto a wall. CPX terminals with four or more interlinkingblocks require additional mounting components for the electric modules.

Tab.�2/2: Methods of fitting the CPX terminal

2.4.1 Fitting CPX terminals without pneumatics onto a H−rail

For fitting the CPX terminal without pneumatics onto an H−rail,you will require mounting kit type CPA−BG−NRH. This kit con�tains 2�clamping components and 2�M4x12 screws.

Fitting onto an H−rail is carried out in the same manner asfitting CPX terminals with pneumatics onto an H−rail (see sec�tion�2.4.2).

2. Assembly


2.4.2 Fitting CPX terminals with pneumatics onto an H−rail

For fitting the CPX terminal onto an H−rail you will requiremounting kit type CPX−CPA−BG−NRH. This kit contains3�clamping components and 3�M4x12 screws.

CautionH−rails with mounted valve terminals can break if they aresubjected to vibration exceeding severity level 1:

� 0.15 mm path at 15 ... 85 Hz

� 2 g acceleration at 58 ... 150 Hz

This can damage the valve terminal, your machine or yoursystem.

· In this case use wall mounting.

· Note the permitted values for vibration and shock inappendix A.1 �Technical data".

Caution� H−rail mounting without an H−rail clamping unit is notpermitted.

· If the terminal is fitted in a sloping position or if it is sub�jected to vibration, secure the H−rail clamping unit addi�tionally� against sliding down with the retaining screws intended for this purpose (see 3 in Fig.�2/11)

� against unintentional loosening/opening.

2.4.3 Fitting CPX terminals with Midi/Maxi pneumatics onto an H−rail

For fitting the valve terminal onto the H−rail you will require anH−rail clamping unit type CPX−03−4,0 (Midi) or typeCPX−03−7,0 (Maxi).

Caution� H−rail mounting without an H−rail clamping unit is notpermitted.

· If the terminal is fitted in a sloping position or if it is sub�jected to vibration, secure the H−rail clamping unit addi�tionally� against sliding down with the retaining screws intended for this purpose (see Fig.�2/13, item 6)

� against unintentional loosening/opening.

Note� If the terminal is fitted in a horizontal position and theload is at rest, it is not necessary to use the screws tosecure the H−rail clamping unit (see Fig.�2/13, item 6).

� If your CPX terminal does not have an H−rail clampingunit, you can order this and fit it at a later stage.

� The existing end plates (MIDI/MAXI) determine whetherMIDI or MAXI clamping elements are to be used.

Fasten the H−rail clamping unit to the rear of the right−handend plate and the pneumatic interface as described below.

Before fitting

· Glue the rubber feet on (�4 in Fig.�2/13). Make sure thatthe surfaces to be glued are clean (clean with spirit).

· Tighten the flat−head screws (see Fig.�2/13, item 3).

· Make sure that the spacer discs have been removed.

2.4.4 Wall mounting

CautionWhen fitted onto a wall, the CPX terminal can bend and bedamaged in the following cases:

� When fitted to an uneven, flexible surface

� When CPX terminals with Midi/Maxi pneumatics arefitted without spacer discs (see Fig.�2/15)

� When fitted to a wall without additional fastening (seeTab.�2/4)

Fit the CPX terminal only onto a flat fixed surface. Makesure that the spacer discs are fitted before you mount theCPX terminal with Midi/Maxi pneumatics.

The end plates and the pneumatic interface contain holes forfitting the terminal onto a wall.

Spacer discs for Midi/Maxi pneumatics

To compensate for the differences in height between thepneumatic and electrical sides, you have to fit spacer discsfor a CPX terminal with Midi/Maxi pneumatics. Fit two spacerdiscs on each of the following:

� On the pneumatic interface for Midi/Maxi

� On the end plate

The spacer discs have one self−adhesive side to simplify theassembly process. Remove the protective foil before mount�ing.

Note Fig.�2/15 and the relevant fitting instructions.

3.1 General installation instructions

NoteObserve the following if the UL requirements are to becomplied with in your application:

� Rules for observing the UL certification can be found inthe separate UL−specific documentation. The relevanttechnical specifications listed there also apply here.

� The technical specifications in this documentation mayshow different values.

WarningUncontrolled movements of the connected actuators anduncontrolled movements of loose tubing can cause injuryto human beings or damage to property.

Before carrying out installation and maintenance work,switch off the following:

� Compressed air supply

� The operating and load voltage supplies.

3.1.1 Connecting cable

Field bus cable Use a suitable cable for your field bus system. Refer to themanual for your controller for the type of cable to be used.Also take into account here the distance and the fieldbusbaud rate.

Operating voltage cable Use a cable for the operating voltage with sufficient cross−sectional area. Avoid long distances between the power unitand the CPX terminal. Long operating voltage cables reduce thevoltage supplied by the power unit.

If necessary, ascertain the suitable cross−sectional area of thecable and the maximum permitted cable length in accordancewith the general rule in section A.2.

3. Installation


Pre−assembling the connecting cable

CautionThe position of the pins on the plug is different from thaton the socket.

� See the manual for the CPX bus node in question fora�description of the pin assignment of the fieldbus inter�face.

� See manual �CPX I/O modules" for the pin assignmentof the sensor and actuator connections of input and out�put modules.

� The operating voltage and load voltage connections arein the form of plugs. The pin assignment can be found inthe following sections.

Use plugs and sockets from the Festo supply programmewhich match the outer diameter of the cables used.

3. Installation


Pre−assembling the plugsand cables

Connect the plugs and cables as follows (example):

1. Open the plugs/sockets as follows:

· Power supply socket:Insert the mains power socket into the operating volt�age connection of the CPX terminal. Unscrew thehousing of the socket.Then remove the connecting part of the socket, whichis inserted in the operating voltage connection.

· Fieldbus socket and sensor plug (only with PG...):Loosen the centre knurled nut.

3. Remove 5 mm of insulation from the end of the conduc�tors and fit cable−end sleeves on the stranded wires.

4. Connect the ends of the conductors.

3. Installation


5. Replace the connecting part on the housing of the plug/socket. Pull the cable back so that there are no loops in�side the housing.

6. Tighten the strain relief.

3.1.2 Configuration of the CPX bus node

The characteristics of the CPX terminal can be adapted tovarious requirements.

Settings on the CPX busnode

CPX terminals can be coupled to various fieldbuses. Coupling is made via a CPX bus node that is adapted to suit the relevant fieldbus. The following settings can bemade, depending on the CPX node used:

� The fieldbus configuration (e.g. fieldbus address)

� Error characteristics of the CPX terminal

� Diagnostic behaviour of the CPX terminal

Depending on the CPX bus node used, important, application−specific settings can be made, if applicable, with DIL switcheson the CPX bus node. The DIL switches are behind an easilyaccessible cover on the CPX bus node.

Information about the installation and the setting options foryour CPX bus node can be found in the manual for the CPXbus node.

3. Installation


3.1.3 Configuration of the pneumatics

MPA pneumatics

From a technical point of view, the individual MPA pneumaticmodules on the CPX terminal each represent an electric mod�ule with digital outputs for controlling the valves fitted. In thecase of VMPA1−FB−...−8, 8�digital outputs will always be as�signed and in the case of VMPA2−FB−...−4, 4�digital outputswill always be assigned.

VTSA, Midi/Maxi or CPA pneumatics

From a technical point of view, the pneumatic interfaces onthe CPX terminal are electric modules with digital outputs.

NoteWhen the pneumatics have been converted or extended,the number of output addresses occupied by the pneuma�tics for 8, 16, 24 or 32 outputs must be set on a DIL switchon the pneumatic interface.

The DIL switch is situated under the transparent cover on thepneumatic interface.

Detailed information on the pneumatic interfaces and MPApneumatic modules can be found in the manual for the �CPXI/O modules" of type P. BE−CPX−EA−...

3. Installation


3.1.4 Selecting the power supply unit

Warning· Use only PELV circuits as per IEC/DIN EN 60204−1 for theelectric power supply (protective extra−low voltage,PELV).Also observe the general requirements for PELV circuitslaid down in IEC/DIN EN 60204−1.

· Use only power sources that guarantee reliable electri�cal isolation of the operating voltage as per IEC/DIN�EN�60204−1.

Protection against electric shock (protection against directand indirect contact) is guaranteed in accordance with IEC/DIN EN 60204−1 by using PELV circuits (electrical equip�ment of machines, general requirements).

The current consumption of a CPX terminal depends on thenumber and type of integrated modules and components.

Recommendation:

· Use regulated power supply units, to ensure that the loadvoltage of the outputs remains within the permitted toler�ances even during continuous operation.

· Select power supply units that provide sufficient outputreserves for later extensions to the CPX terminal.

NoteWhen selecting the power supply units, check that theyhave sufficient output. If necessary, ascertain the currentconsumption according to the following tables.

3. Installation

3. Installation


3.1.5 Power supply of the CPX terminal

NoteCheck within the framework of your EMERGENCY STOPconcept to ascertain the measures necessary for puttingyour machine/system into a safe state in the event of anEMERGENCY STOP (e.g.�switching off the operating voltagefor the valves and output modules, switching off the com�pressed air).

NoteWhen supplying power to CPX terminals with connectedpneumatics:

· Note that the lower tolerance range of the pneumaticsmust be observed when the operating and load voltagesupplies are provided by a power unit.Tolerance ranges:− MPA pneumatics: ±25�%,− VTSA pneumatics: ±10�%− Midi/Maxi pneumatics:±10�%− CPA pneumatics: +10/−15�% or − CPX−CP interface: +10/−15�%.

Power is supplied to the CPX terminal (in the form of operat�ing and load voltages) via supplies in the interlinking blocks(see section�1.1.3 for an overview of the supplies). These con�duct the operating and load voltages to the neighbouringmodules.

3. Installation


Supplying operating and load voltage

Interlinking blocks withsystem supplyTypes CPX−(M−)GE−EV−S...

The operating and load voltages for the CPX terminal aresupplied via these interlinking blocks. The voltages are sup�plied via an M18, 7/8" or push−pull plug and can be used forfurther electric modules and for the valves on either side.

If interlinking blocks with additional supply are not required,the interlinking block with the system supply can be fitted inany desired position.

If interlinking blocks with additional supply are required,these must always be placed to the right of the system supply(see also Fig.�3/2).

Interlinking blocks withadditional supply for elec�tric outputsTypes CPX−(M−)GE−EV−Z...

The additional load voltage for the electric outputs is sup�plied via these interlinking blocks. The load voltage for theoutput modules is also supplied via an M18, 7/8" or push−pull plug and can be switched off separately. These interlinking blocks must always be placed to the rightof a system supply and, in the case of a push−pull connec�tion, must not be combined with a forwarding functionwithin a CPX terminal.

The use of interlinking blocks with additional supply for elec�tric outputs causes the following (see also Fig.�3/2):

� The load voltage for electric output modules will beinterrupted to the previous module on the left.

� The load voltage supplied will be available to the inte�grated module and, where applicable, to the followingmodules on the right.

� The operating and load voltage supplies for the valveswill be transmitted further.

� Several additional supplies for electric outputs in aCPX terminal are possible.

3. Installation


Interlinking block withadditional power supplyfor valves Types CPX−GE−EV−V...

These interlinking blocks enable separate circuits to becreated for supplying load voltage to the valves. The loadvoltage for the valves, which is also supplied via an M18 or7/8" plug, can be switched off separately. This interlinkingblock must also always be placed to the right of a systemsupply.

The use of interlinking blocks with additional supply forvalves causes the following (see also Fig.�3/2):

� The load voltage for the valves will be interrupted at theprevious module on the left.

� The load voltage supplied is available for the followingmodules:

� Subsequent pneumatic modules/valves to the right

� CP modules that are connected to the fitted CPX−CPinterface and to those CPX−CP interfaces subsequentlyfitted to the right

� The operating and load voltage supplies for the electricoutputs will be transmitted further.

� These additional supplies must not be used for MPApneumatics with MPA electronic modules of the typeVMPA...−FB−EMS−... (see description of P.BE−MPA−ELEK�TRONIK−...).

Interlinking blocks withpush−pull forwardingfunction of type CPX−M−GE−EV−S−PP−5POL

These interlinking blocks are used to forward the powersupply to subsequent external equipment. These interlinking blocks must be placed directly to the rightof a system supply and must not be used more than oncewithin a CPX terminal. They must not be combined with anadditional supply, either.

3. Installation


CautionDamage to device and the environment

CPX terminals with push−pull forwarding function musthave external fuse protection to 16�A in order to avoidoverloading and resultant damage to the device and itsenvironment.

The use of interlinking blocks with forwarding function forsupplying power to subsequent equipment causes the follow�ing (see also Fig.�3/2):

� The operating voltage supply and the load voltagesupply are forwarded/connected through to subse�quent equipment via the push−pull connection. Thisreplaces a T−adapter in the field.

� The operating voltage supply and the load voltagesupply are available to the fitted output module andsubsequent output modules to the right.

� Interlinking blocks with a push−pull forwarding func�tion are identically constructed to those with a�push−pull system power supply

Interlinking blocks withoutsupplyTypes CPX−(M−)GE−EV

These interlinking blocks serve for the electrical linking ofmodules which do not require a separate load voltage supply.

3. Installation


Internal voltage forwarding

The operating voltage supplied (internal electronics/inputs)and load voltage (valves/outputs) are forwarded in the inter�linking blocks via what are known as contact rails. Fig.�3/2and Fig.�3/3 show the differences between 4−pin and 5−pinalternative connections:

Special features concerning the use of the CPX−CP interface

NoteThe CPX−CP interface connects the current rails 0�Vel/senand 0�Vval of the CPX valve terminal. This means that theseparate circuits for the operating voltage for the electro�nics/sensors (Vel/sen) and the load supply for the valves(Vval) will no longer be effective until the next additionalsupply for valves following the CPX−CP interface.

Further information on the power supply for the CPX terminalin conjunction with the CPX−CP interface can be found in themanual for the CPX−CP interface in the section �Installation" �section �Power supply concept − forming voltage zones."

Pin allocation for the alternative connections


Provide external fuse protection for the system supply andadditional supplies. The permissible current per pin at thesupply is:

� 7/8" plug, 4−pin: max. 10�A 1) 2)

� 7/8" plug, 5−pin: max. 8�A 1)

� M18 plug (4−pin): max. 16�A 2)

Potential equalisation

The CPX terminal has two earthing connections for potentialequalisation:

� The �functional earth" pin from system supply, additionalsupply or valve supply (see Tab.�3/4)

� Earth connection on the left−hand end plate (see Fig.�3/4).

Note· Always connect the �functional earth" to the earth po�tential.

· Connect the earth connection of the left−hand end plateto the earth potential with low impedance (short cablewith large cross−sectional area).

· With low−impedance connections you can ensure thatthe earth connection at the left−hand end plate and theearth connection at the supplies have the same potentialand that there are no equalising currents.

You can thereby avoid interference from electromagneticsources and ensure electromagnetic compatibility in accor�dance with EMC directives.

Connection examples

Connection example 1 Fig.�3/4 shows as an example the connection of a common24�V supply for pin�1 and pin�2 on the M18 plug. Please notethat:

� The tolerance of 24�V�DC ±25�% must be observed.

� Both connections for potential equalisation are connectedand that compensating currents must be prevented

� The load voltage at pin�2 of the M18 plug (valves and out�puts) can be switched off separately

� External fuses are used, depending on the application(maximum value at pin �0�V" in total for both fuses: 16�A)

4.1 Procedure for commissioning

In order to avoid connecting errors and addressing errors,you should carry out commissioning in steps as follows. The individual commissioning steps are shown in Fig.�4/1.

1 Step 1 � Checking the valve/cylinder combinations (see manual for the specificpneumatics)

2 Step 2 � Checking the I/O assignment

3 Step 3 � Commissioning the CPX terminal on the fieldbus and checking theaddress assignment, if necessary, without connected actuators by means ofLED (see manual for the specific CPX bus node)

Fig.�4/1: Commissioning steps

4. Commissioning


4.2 Preparing the CPX terminal for commissioning

CPX terminals can be connected to various fieldbuses. Connection is made via the CPX bus node that is adapted tosuit the relevant fieldbus.

The reaction of the CPX terminal can be adapted to variousrequirements. You can carry out important settings as follows:

� With the DIL switch directly on the CPX bus node (seesection 3.1.2).

� By parametrisation (see section 4.2.1).

The DIL switch and the parameters are preset at the factory.

CautionIncorrectly set DIL switches and parameters can causedamage during operation. You must observe the followinginstructions in order to prevent damage.

· Check the DIL switch settings before using and replacingCPX terminals.

· Make sure that the desired parametrisation of the CPXterminal in the start−up phase or after fieldbus interrup�tions is carried out by the plug−in module or the scanner/bus master, providing this is supported by the fieldbusprotocol used. This is to ensure that if the CPX terminal isreplaced, the new terminal will also be operated with thedesired parameter settings.

Preparations Before commissioning a fieldbus system with CPX terminals,you should first prepare each individual CPX terminal forcommissioning.

4. Commissioning


NoteDo not connect the cables for the fieldbus when preparingfor commissioning.

In this way, you can avoid:

� Addressing errors that may occur due to the modificationof the address range during operation with variousfieldbus systems.

Proceed with preparation as follows:

1. Check the pneumatic tubing of the valve terminals withthe aid of the manual override (see manual for specificpneumatics).

2. Check the entire electric wiring of the CPX terminal.

3. Check the DIL switch settings of your CPX terminals (see manual for the specific CPX bus node).

4.2.1 Parameter types

The parameters are preset at the factory. These pre−settingscan be used for a large number of applications. With the aidof parametrising, the characteristics of the CPX terminal orthe characteristics of the individual modules and I/O chan�nels can be adapted to each particular application.

The possibilities available depend on the fieldbus protocolused. Information about this can be found in the manual foryour CPX bus node.

A distinction is made between the following types of para�meters:

4. Commissioning


4.3 Start−up behaviour of the CPX terminal

The desired parametrisation of the CPX terminal should becarried out in the start−up phase or after fieldbus interrup�tions by the plug−in module or the scanner/bus master, pro�viding this is supported by the fieldbus protocol used. In thisway you can be sure that when a CPX terminal has been re�placed, the new terminal is operated with the same para�meter settings.

You can influence the start−up behaviour with the aid of thesystem parameter System start (see section B.2.2). If possibleselect the setting �System start with default parameterisingand current CPX system equipment". The desired parameter�ising can then be created in the start−up phase or after field�bus interruptions e.g. by the plug−in module or the scanner/bus master (depending on the fieldbus used).

If the M�LED lights up permanently after the system start,then �System start with saved parametrising and saved CPXsystem equipment" is set.

CautionIn the case of CPX terminals on which the M−LED lights uppermanently, parametrising will not be restored automati�cally by the higher−order system if the CPX terminal is re�placed after servicing. In these cases check before repla�cing to see which settings are required and carry out thesesettings.

Detailed instructions can be found in the manual for the spe�cific CPX bus node or the manual for the handheld.

5.2 Diagnosis via status bits or the I/O diagnostic interface

The CPX terminal offers the following two modes for diag�nosis, irrespective of the CPX bus node used:

Mode Description

Status bits(system status)

The status bits serve for displaying com�mon diagnostic messages (global faultmessage). Access to the status bits ismade via 8 internal inputs (see section5.2.1).

I/O diagnostic inter�face (system diagno�sis)

The I/O diagnostic interface is a fieldbus−independent diagnostic interface.With this interface, all internal data andparameters can be read out via 16 internalinputs and 16 internal outputs (see sec�tion 5.2.2 and Appendix B). All diagnosticinformation is then also available even ifthe fieldbus protocol used does not offerany extensive diagnostic functions.

Tab.�5/2: Fieldbus−independent diagnostic modes



5.2.1 Structure of the status bits

Irrespective of the CPX bus node used, the CPX terminal pro�vides 8�status bits for displaying common diagnostic mess�ages (global error messages).

Status bits are configured like inputs. The input addresses,which are to be assigned to status bits, depend on the field�bus protocol used (see manual for the specific CPX busnode).

The status bits supply coded diagnostic information. Bits 0 to3 specify the module types in which faults have occurred. Bits4 to 7 specify the type of fault.

If different faults occur simultaneously on different types ofmodules, faults cannot be distinguished. Use the I/O diag�nostic interface in order to distinguish faults clearly.



5.2.2 The I/O diagnostic interface

Organisation of internal data and parameters

Internal data and parameters of the CPX modules and of theCPX terminal are stored in a common memory range. Withthe�I/O diagnostic interface, read access can be made withthe aid of the function number to individual bytes of thismemory range.

Parameters can be modified with the aid of fieldbus−specificfunctions (depending on the fieldbus used) or with the hand�held (see also section 4.2.2).

Method of operation of the I/O diagnostic interface

Detailed diagnostic information can be accessed via the I/Odiagnostic interface. You can ascertain exactly, e.g. on whichmodule and on which channel a fault has occurred. 16 inputbits and 16 output bits, via which all diagnostic data can beread, are available for accessing the system diagnosis.

The addresses of the input and output bits of the I/O diag�nostic interface depend on the fieldbus used (see the manualfor the specific CPX bus node).



Output bits The function number of the desired data will be specified inbinary coded form via the output bits A0 ... A12 of the I/Odiagnostic interface. The function number is accepted whencontrol bit A15 supplies a 1−signal.

With the aid of the module number of the faulty module youcan ascertain the function numbers of the relevant modulediagnostic data (see also section B.2.7). Module diagnosticdata can be e.g.:

� The number of the faulty channel

� The module fault number.

With the following function number, you can ascertain e.g. themodule fault number of module 5:

5.2.3 Error numbers

Detailed information on module−specific diagnosis can befound in the manual for the relevant module.

Possible faults of the CPX terminals are divided into threeerror classes with different priority depending on the serious�ness of the fault. If a fault occurs, the system error LED (SF LED) will flash depending on the error class.

Error class Flashing sequence of theSF LED

Error weighting Priority

1 1 * flashes, pause time Simple (e.g. simple user fault) low

2 2 * flashes, pause time Medium (standard diagnosisand extended diagnosis)

medium

3 3 * flashes, pause time High (hardware fault/internalfault)

high

Tab.�5/7: Error classification

If several errors occur together, the error with the highestpriority will have precedence. This means that:

� The system error LED flashes according to the higherpriority

� The number of the error with the higher priority will beentered in the system diagnostic data under functionnumber�1938 (error number).

Within an error class, errors of modules with a lower modulenumber have higher priority, e.g. errors of module number�0have the highest priority within a specific error class. Errors ofmodule number�1 have the second highest priority, etc.

A.2 Cable length and cross−sectional area

NoteIn the following section it is assumed that the reader isfamiliar with the information in the chapter �Installation" inthis manual. This section is directed exclusively at person�nel trained in electrotechnology.

A load−dependent drop in voltage occurs on the cables of theoperating voltage supply to a CPX terminal. This can causethe voltage at pin�1 or pin�2 of the operating voltage connec�tion to be outside the permitted tolerance.

Recommendation:

· Avoid long distances between the power supply unit andthe CPX terminal.

· Ascertain the most suitable cross−sectional area and themaximum cable length for the operating voltage cable inaccordance with the following formula.

NoteThe following formula assumes that the cross−sectionalareas of the operating voltage supply are the same.



Ascertain by formula

Proceed as follows:

1. Calculate the maximum current consumption of the inputsand electronics (I1) as well as of the outputs and val�ves�(I2).

2. Ascertain the lowest voltage to be expected during opera�tion (VBmin) on the power unit. Take the following intoaccount:

· The load dependency of the power supply unit

· The fluctuations in the primary voltage

· The operating temperature of the equipment

3. Enter the values in the relevant formula. The equivalentcircuit diagram as well as the example explain the correla�tions.

B.1 Access to internal parameters and data

The CPX terminal permits access to internally saved data andparameters. The ways in which you can access these data andparameters depend on the fieldbus protocol used. Forexample access can be made via:

� The plug−in module or scanner/bus master; e.g. for guar�anteeing the desired parametrisation of the CPX terminalin the start−up phase or after fieldbus interruptions

� Fieldbus−specific configurators, e.g. during the commis�sioning phase or during a search for faults

� The user program in the higher−order PLC/IPC, e.g. formodifying parameters or system features during oper�ation

� The handheld, e.g. during the commissioning phase orduring a search for faults

� The I/O diagnostic interface, e.g. for reading out diagnos�tic data.

Data can be read. Parameters can be read and modified.

Only read access to parameters and data by means of therelevant function number is possible via the I/O diagnosticinterface (see section 5.2.2).

C.1 Input debounce time

Fundamentals

Input debounce times are specified in order to eliminate in�terfering changes of signal edge during switching procedures(bouncing of the input signal). For example, mechanicalswitches generate brief undesired signal edges during switch�ing procedures. The signal states which are thereby producedcan cause interference in the control sequence and shouldtherefore frequently be suppressed.

Interfering, undesired signal edges can be suppressed bya�PLC program in the higher−order controller. Interference cantherefore be avoided. With the CPX terminals, undesired sig�nal edges can be suppressed simply by parametrisation.

CPX parametrisation

With the CPX terminals, the input debounce time can be setwith an appropriate module parameter. The possible inputdebounce times therefore depend on the particular type ofmodule. Typical input debounce times are: 0.1�ms, 3 ms (typi�cal presetting), 10 ms and 20 ms.

Mode of operation

Changes of edge in the sensor signal will be accepted as alogical input signal (see Fig.�C/1) only when the specifieddebounce time has expired.

C.2 Signal extension

Fundamentals

Signal extension times are specified when very short signalsare to be taken into account in the control process. Shortsignals can occur, e.g. when an intermediate position is ex�ceeded and evaluation is necessary in order to produce atime−optimised consequent process before an end position isreached.

Depending on the type of sensor, the length of the signal,which is generated when the intermediate position is ex�ceeded, can fluctuate according to the positioning speed.There is a danger here that the short signals are not always�recognised" due to long cycle times of the higher−order controller.

With CPX terminals, a signal extension time can be defined byparametrisation of the appropriate input signal. Short signalswill then also be recognised reliably by the higher−order con�troller.

CPX parametrisation

With the CPX terminals, the signal extension time for the mo�dule is set with the appropriate module parameter. The poss�ible signal extension times depend on the type of module.Typical signal extension times are: 0.5�ms, 15 ms, 50 ms and100 ms.

The signal extension time for each channel can be activatedor deactivated with a further channel−orientated module para�meter. When preset, the signal extension time is inactive.



Mode of operation

Signal states accepted as logical input signals usually remainvalid at least until the specified minimum signal duration hasexpired. Change of edge within the minimum signal durationare ignored (see Fig.�C/2). Fixed debounce times remain ef�fective.

Obtain further information on Idle mode, Fail safe and Forcingfrom the following sections.



C.3.1 Force

Fundamentals

The function Force permits the manipulation of signal statesindependent of actual operating conditions. Force enablesinput and output signals to be overwritten, Input signalsactually present or changes of status by program will be ig�nored. The input signals actually present and the output sig�nals generated by the user program only become valid againwhen the function Force is deactivated.

WarningDepending on the functions of the machine/system, themanipulation of signal states can lead to serious personalinjury or material damage.

Use the Force function very carefully, in order to avoid damage.

The �Force" function is used mainly in the commissioningphase in order to set certain signals to the desired status fortest purposes even if the wiring is not complete.

CPX parametrisation

With CPX terminals, Force parametrisation can be used for:

� Digital inputs

� Digital outputs

� Valves

� I/Os of the I/O diagnostic interface and status bits

� Analogue inputs

� Analogue outputs



By means of a system parameter, Force is enabled globally forthe CPX terminal or blocked.

C.3.2 Signal status in the event of a fault (Fail safe)

Fundamentals

With the aid of the so−called fail−safe parametrisation, thesignal status which the outputs are to assume in the event offieldbus communication faults, can be determined (fail−safestatus). In this way, a defined machine/system status shouldbe created in the event of fieldbus communication faults (e.g.failure of the higher−order PLC/IPC).


Use the Fail−safe parametrisation very carefully, in order toavoid damage.

CPX parametrisation

With CPX terminals, fail−safe parametrisation can be used for:

� Digital outputs


� Valves

By means of the system parameter fail−safe, you can globallydetermine the signal status which the outputs/valves are toassume in the event of fieldbus communication faults, e.g. inthe event of:

� Communication failure (fieldbus interruption, PLC failure)

� Communication stop

C.3.3 Signal status in Idle status (Idle mode)

This function is only relevant with certain fieldbus protocols(see manual for CPX bus node).

Fundamentals

Idle mode parametrisation helps determine which signalstatus outputs/valves should take when changing into theIdle status. In this way a defined machine/system statusshould be created.


Use the Idle mode parametrisation very carefully, in orderto avoid damage.

CPX parametrisation

With CPX terminals, Idle mode parametrisation can be usedfor:

� Digital outputs


� Valves

By means of the system parameter Idle mode, you can glo�bally determine the signal status which the outputs/valvesare to assume when changing into the Idle status.

C.4 Diagnostic memory

Fundamentals

A diagnostic memory serves for protocolling fault states. Ifthe time when faults occur and if fault sequences are regis�tered, this will facilitate the search for the cause of the faultswhich are otherwise difficult to locate. If the causes are elim�inated, faults can be avoided over long periods.

CPX parametrisation

Various diagnostic memory filters can be parameterised bymeans of diagnostic memory parameters (see section B.2.4).With these filters the registering of certain system states canbe suppressed, and both starting and stopping can be con�trolled. The method of operation of the diagnostic memoryfilters is shown in Fig.�C/10.

Fig.�C/10: The method of operation of the diagnostic memory filters



Mode of operation

With the CPX terminals the start and end of a fault can beprotocolled in the internal diagnostic memory. The diagnosticmemory contains up to 40�entries. In addition to informationon localising the fault, the relevant time point is saved,measured from the moment the power supply is switched on.A diagnostic entry consists of 10�bytes. The first five bytescontain information on the time point. The last five bytes con�tain information on the fault (see section B.2.5).

With the aid of the function number, entries in the diagnosticmemory can be read out via the I/O diagnostic interface irre�spective of the fieldbus protocol used. The various fieldbusprotocols provide, where applicable, further possibilities forreading out and configuring the CPX diagnostic memory (seethe manual for the specific CPX bus node).



C.5 Monitoring errors

Fundamentals

Monitoring functions that run automatically can be activatedand deactivated by parametrisation.

The activation of monitoring functions helps to guarantee thefunctionality of the machine/system and to avoid unnecess�ary idle periods. The deactivation of monitoring functionshelps to avoid disturbing error messages, e.g.:

� During commissioning

� During an EMERGENCY STOP, if the EMERGENCY STOPconcept of the machine/system requires that the loadvoltage for the valves and output modules be switchedoff. The error messages (e.g undervoltage), which aretriggered when the load voltage is switched off, should be frequently suppressed here.

CPX parametrisation

The CPX terminal permits the monitoring of various types offault (e.g. short circuit, wire fracture, undervoltage, etc.). Thedifferent monitoring functions can be activated or deactivatedglobally by system parameters for the complete CPX terminaland by module parameters for a single CPX module or anindividual channel. Activation of a monitoring function causesthe following:



Monitoring Reaction to activation

Module parametersMonitoring

A fault on the module will be:� Forwarded to the CPX bus node� Displayed by the module common error LED

System parametersMonitoring

A fault registered by the module will be:� Sent to the higher−order fieldbus master� Displayed by the red SF−LED on the CFX bus node� Entered in the module diagnostic data and, if applicable, in the

status bits� Entered, if applicable, in the diagnostic memory

Tab.�C/8: Monitoring

The behaviour of the channel fault LED is normally controlledby hardware functions and does not therefore depend on thesetting of the monitoring functions.

The following monitoring functions can be activated or deacti�vated globally:

System parameter monitoring Description

Undervoltage of valves Monitors the load voltage supply for the valves

Undervoltage of outputs Monitors the load voltage supply for the outputs

Short circuit/overload of outputs Monitors whether outputs are overloaded or short circui�ted

Short circuit/overload, sensor supply Monitors whether sensor supply is overloaded or shortcircuited

Tab.�C/9: System parameter monitoring



The following monitoring functions can be activated or deactivated by modules, providing the module supports the relevant monitoring function:

Module parameter monitoring Description

Short circuit/overload, sensor supply Monitors whether sensor supply is overloaded or shortcircuited

Short circuit/overload of outputs Monitors whether outputs are overloaded or short circuited

Undervoltage for outputs/valves Monitors the load voltage supply for the valves/outputs

Short circuit/overload at the valve Monitors whether valve outputs are overloaded or shortcircuited

Upper/lower limit value Monitors the upper/lower limit

Parametrisation error Monitors module parametrisation (plausibility check)

Monitoring wire fracture (channel−specific)

Monitoring can be activated and deactivated for eachchannel (0 = inactive; 1 = active).

Tab.�C/10: Module parameter monitoring

The meaning of the module parameter depends on the mo�dule used. Detailed information can be found in the manualfor the relevant module.
