1.3 Connecting to the field bus

1.3.1 Field bus cable

Please note

With incorrect installation and high baud rates, data trans�

mission errors may occur as a result of signal reflexions

and attenuations.

Causes of the transmission errors may be:

� missing or incorrect terminating resistor

� incorrect screening connection

� branch lines too long

� transmission over long distances

� unsuitable cables.

Observe the cable specifications. Refer to the manual for

your controller for information on the cable type.

Use a twisted, screened 5−wire cable for the field bus. The

bus interface is supplied with power via the field bus cable.

Alternatively, you can use the bus cables of other manufac�

turers (see also Appendix A, Accessories).

Please note

If the valve terminal is fitted onto the moving part of a ma�

chine, the field bus cable on the moving part must be pro�

vided with strain relief. Please observe the relevant regula�

tions in IEC/DIN EN 60204−1.

1. Installation


1.3.2 Field bus baud rate and field bus length

The maximum permitted field bus length depends on the

baud rate used. Fig.�1/11 shows the guideline values.

Detailed information can be found in the manuals for your

control system or scanner.

The maximum permitted length of the branch line depends on

the total length of the branch lines and the baud rate.

Please note

S Refer to the manuals for your control system or bus in�terface for information on the T−adapter and the maxi�

mum branch line length which is permitted for your con�

troller.

S When ascertaining the maximum permitted length of thefield bus cable, take into account also the sum of the

branch line lengths.

Avoid long distances between the bus interfaces/logic supply

and the CPV Direct.

Caution

S Make sure the polarity is correct when you connect thefield bus interface and the power supply for the bus

interface/internal�logics.

S Connect the screening/shield.

Please note

Bus slaves of different manufacturers show different toler�

ances in respect of interface power supply. Take this into

consideration when planning the bus length and placing

the power unit.

The following tolerance of the bus interface supply applies to

the CPV Direct (pin 2 with the micro style connection or pin�5

with the open style connection):

Vmax = 30.0 V

Vmin = 11.0 V

Recommendation:

Place the power unit in or near the centre of the bus.

Sub−D socket. This is to prevent equalizing currents flow�

ing through the screening of the field bus cable (Fig.�1/18).

With this plug, contact with the screening cable is made via

the cable clip. This connects the incoming and outgoing cable

screening. With a 5−core cable, you can therefore cut off the

screening cores.

1. Installation


1.4 Bus termination with terminating resistors

Please note

Use a bus termination at both ends of the bus segment.

This also applies when the module or the interface is at the

beginning of a bus cable.

If the CPV valve terminal is at the end of the field bus system,

a bus termination will be required.

If you are using T−adapters, we recommend that you install

the terminating resistor at the unused output of the

T−adapter.

Recommendation:

Fit a resistor (120�Ω, 0.25 W) for the bus termination betweenthe connections for CAN_L and CAN_H. Fig.�1/19 shows this

as an example with the open style connection.

1.5 Power supply

1.5.1 Cable for power supply

S Use a power supply cable with sufficient cross−sectionalarea.

S Avoid long distances between the power unit and the CPVvalve terminal. Long cables reduce the voltage supplied

by the power unit.

S If necessary, ascertain the suitable cross−sectional areaand the maximum permitted cable length.

The connection for the power supply is in the form of a plug.

The pin assignment of the plug can be found on the following

pages.

For connecting the power supply, use plugs from the Festo

range which correspond to the outer diameter of the cable

used (see Appendix A.2).

Preparing When you have selected suitable cables connect them as

follows (Fig.�1/20):

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 conductor.

5. Replace the connecting part back onto the housing of the

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

the housing.

6. Tighten the strain relief.

1. Installation


1.5.2 Selecting the power unit�

Warning

S Use only PELV circuits as per IEC/DIN EN 60204−1 (Pro�tective Extra−Low Voltage, PELV) for the electrical supply.

Consider also the general requirements for PELV circuits

in accordance with IEC/DIN EN 60204−1.

S Use power supplies which guarantee reliable electricalisolation of the operating voltage as per IEC/DIN EN

60204−1.

By the use of PELV circuits, protection against electric shock

(protection against direct and indirect contact) is guaranteed

in accordance with IEC/EN 60204−1 (Electrical equipment for

machines, General requirements).

The current consumption of a CP system depends on the

number of CP modules valve coils.

Recommendation:

S Used closed−loop power units.

S When selecting the power units, check that they havesufficient output. If required, ascertain here the total cur�

rent consumption according to the following table.

1. Installation

sumption for a CP system. The values specified have been

rounded up.

1) Current consumption depends on valve type (see Technical

specifications for the valves).

1. Installation


1.5.3 Connecting the power supply

Warning

If the valve terminal is supplied with load voltage via an

output of a �safety I/O module", switch−on test pulses of

the �safety I/O module" can cause unexpected reactions

of the valve terminal.

S Make sure that these switch−on test pulses are reliablysuppressed or switched off.

Use only a 4−pin M12 socket for the power supply and con�

nect this only to the connection for the power supply (see

Fig.�1/1).

The current consumption depends on the type of valve ter�

minal. Please refer to the �Pneumatics manual, P.BE−CPV−.."

and the previous chapter for the values.

When connecting the 24 V load voltage (pin�2), observe the

following:

S Observe the tolerance (20.4 V DC ... 26.4 V). Check the 24 V load voltage of the valves while your system is oper�

ating.

Caution

Protect the load voltage of the CPV valve coils externally

with a fuse max. 2 A.

In this way you can avoid functional damage to the CPV

Direct in the event of a short circuit.

1. Installation


Please note

Check within the framework of your EMERGENCY STOP

circuit, to ascertain the measures necessary for putting

your machine/system into a safe state in the event of an

EMERGENCY�STOP.

� Switch off the load voltage of the valves and output

modules in the secondary circuit of the power unit.

� Switch off the compressed air supply to the valve

terminal.

Due to energy being stored in the input circuit of valve

terminals, there may be a delay when the load voltage is

switched off before the valves are switched off.

Take this into consideration as follows:

� Register the fact that the load voltage is switched off

by means of an input signal in the controller.

� Block the control signal of the valves by locking the

output signal with the input signal �load voltage".

Potential equalization

The CPV valve terminal has two earthing connections for

potential equalization:

� on the power supply connection

� on the end plate.

Please note

S Always connect the earth potential to pin 4 of the powersupply connection.

S Connect the earth connection of the left−hand end platewith low impedance (short cable with large cross−sec�

tional area) to the earth potential.

S With low−impedance connections you can ensure thatthe housing of the valve terminal and the earth connec�

tion at pin 4 have the same potential and that there are

no equalizing currents.

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

magnetic�influences.

tion will be recognized only if the DIL switch is set cor�

rectly.

Information on setting the DIL switches can be found in

chapter 1.2.2.

1. Installation


You can connect the following CP modules to the CP exten�

sion connection:

� CP input module with 16 inputs, either with 8 x M12 plug

(sockets assigned twice), 16 x M8 plug (sockets assigned

once) or terminals (IP20).

� CP input module (IP20) with 16 inputs.

� CP output module with 8 outputs each with 0.5 A. The

power for the module is also supplied via the CP exten�

sion connection. The load voltage must be supplied

separately via an M18 plug.

� CPV valve terminals of widths 10, 14 and 18 mm. These

are available with 4, 6 or 8 CP valve plates.

� CPV valve terminals of widths 10 and 14 mm.

These are available for field bus connections with max. 8

double−solenoid or 16 single−solenoid valve plates.

Please note

The CPV Direct can be extended by maximum:

� one CP input module

� one CP valve terminal or one CP output module.

1. Installation


Caution

The maximum cable length between the CPV Direct and the

last CP module must not exceed 10 m.

The CP connecting cables must have special electrical

characteristics. Always use, therefore, Festo CP connecting

cables.

You can obtain ready−to−use CP connecting cables from Festo.

These are available in various lengths and types. You will find

a summary in Appendix A.

Seal unused CP connections of your CP system with the rel�

evant seal provided. You will then comply with protection

class IP65.

2.1 Preparing the CP valve terminal for commissioning

2.1.1 Switching on the operating voltage

Please note

Please observe also the switching−on instructions in the

manual for your PLC controller.

S Before switching on, make sure that the specifications onthe field bus configuration are complete and correct.

Please observe the following points when switching on the

power supply:

Common supply If there is a common supply for the control system and for all

the field bus slaves, the power should be switched on via a

central power unit or central switch.

Separate supply If there is a separate supply for the control system and for the

field bus slaves, the power should be switched on in the fol�

lowing sequence:

1. the power supply for all the field bus slaves

2. the power supply for the controller.

2. Commissioning


2.1.2 Address assignment of the CPV valve terminal

The CPV valve terminal with field bus direct connection al�

ways occupies 16 output addresses, irrespective of the

number of valve solenoid coils fitted on it. This enables the

CPV valve terminal to be extended at a later stage without the

need to shift the addresses.

The following diagram shows the addressing sequence of the

individual CPV valve plates.

� A valve location on the CPV valve terminal always oc�

cupies 2 addresses, even if it is fitted with a blanking

plate or pressure−separator plate. If a valve location is

fitted with a double−solenoid valve, the following assign�

ment applies:

� pilot solenoid 14 occupies the lower−value address;

� pilot solenoid 12 occupies the higher−value address.

With single−solenoid valves the higher−value address

remains unused.

2.2 Commissioning on the DeviceNet

Please note

� The Festo valve terminal type CPV...−GE−DN2−8 can be

used on all DeviceNet masters.

� This chapter describes configuration and commissioning

using as an example the controllers from Allen−Bradley.

2.2.1 General information

Please note the following special features when using the CPV

valve terminal on the DeviceNet:

� The I/O addresses of all recognized DeviceNet slaves can

be freely assigned as M−file addresses or as discrete I/Os

in the Scanlist.

� The addresses of network slaves are normally assigned in

ascending order.

� The input and output addresses can be assigned indepen�

dently of each other.

Please note

Order the I/O addresses of the network slaves so that

there is sufficient reserve for later extensions.

The following sections contain generally valid instructions for

configuring a valve terminal on the DeviceNet.

Detailed information can be found in the documentation or in

the help for the configuration program you are using.

2. Commissioning


2.2.2 Configuring DeviceNet slave features (EDS)

When you commission a new DeviceNet slave the first time,

you must inform your configuration program of certain fea�

tures of the slave. The features of the various slaves are

usually administered by the configuration program in a list or

library e.�g. �EDS library" (EDS for electronic data sheets).

The following possibilities are available for extending an

�EDS library":

� Installing an EDS−file

� Entering the slave features by hand.

Installing an EDS−file

Internet Current EDS−files and icons can be found under the following

address in Internet:

� www.festo.com: Go to the Business Area �Pneumatics"

and then to �Download Area".

For the CPV Direct you will require the following files:

File type File name

EDS−file DN2DICP.EDS

ICO file (Icon) DN2DICP.ICO

BMP file (Bitmap) DN2DICP.BMP

EDS file The EDS file contains all the necessary features of valve ter�

minal type CPV...GE−DN2−8. You can install this file with the

aid of your configuration program.

ICO/BMP file Depending on the configuration program used, you can as�

sign the bitmap file or icon file to the valve terminal. The valve

terminal will then be represented accordingly in the configur�

ation program.

2. Commissioning


Instructions on installing an EDS file and an ICO or BMP file

can be found in the manual or in the help for your configur�

ation program.

Entering the slave features by hand

When an EDS file is installed, the following information about

the DeviceNet slave is added to the EDS library. This informa�

tion can also be entered manually.

When the EDS library has been extended, the valve terminal

is entered in the slave list as a possible DeviceNet slave. It

can now be added to a network.

2. Commissioning


2.2.3 Valid instructions for parametrizing on the DeviceNet

When the slave features have been configured (e.g. by instal�

ling the EDS file), the following steps are required for parame�

trizing, depending on the configuration program.

1. Insert the slave in the project/network (online or offline).

If the slave is inserted e.g. offline, it will be selected from

the slave list and added to the network.

2. Assign a slave to a scanner. A network can contain several

scanners. The slave must be assigned to a scanner.

3. Determine the I/O parameters of the slave. The following

specifications are required here:

S The number of I/O bytes to be transmitted. For theCPV Direct, the number depends on the connected

extensions (see chapter 1.6):

− 2 input bytes occupied

− 2 or 4 output bytes occupied.

The table in Fig.�2/3 shows the assignment.

S Specification of communication type. The followingapplies for the CPV Direct:

− �Polled Communication"

or

− �Change of State / Cyclic".

In addition to these communication connnections a

�Strobed I/O" connection must be used in each case

for the diagnosis.

2. Commissioning


Please note

The following applies to an SLC 500 with an Allen−Bradley

scanner type 1747−SDN:

� �Change of State / Cyclic" can be used in combination

with the diagnosis via Strobed I/O only as from software

version V4.015 of the scanner.

� �Polled I/O" with �Strobed I/O" is also supported by

earlier versions.

S Assign the I/O addresses of the slave to the PLC operands.

S Assign 1 diagnostic byte to the PLC operands.

4. Load the configuration into the scanner.

Loading the configuration into the scanner

To conclude, load the configuration into the scanner. Further

information on this can be found in the documentation for

your scanner.

2. Commissioning


2.2.5 Device−specific parametrizing

The CPV Direct supports various device parameters by means

of which you can set the reaction of the valve control and

some status messages. The parameters are set by means of

the �Device Parameter" in the network configurator.

The table in Fig.�2/9 shows how you can address the valve

coils.

The program−controlled access by the PLC is made with the

�Explicit Message" programming. The addresses of the Devi�

ceNet Object Model necessary for this can be found in Appen�

dix B.

Reaction of the outputs in the Fault mode

If communication via the DeviceNet is interrupted, the bus

slaves assume the Fault mode. The reasons for this can be:

� Physical interruption in the network

� Interference by data telegrams.

In the Fault mode, the outputs for the valve control and the

outputs of the output module can assume one of the follow�

ing states:

� Reset the output

� Set the output

� Freeze the current status of the output.

You can determine the status to be assumed for each output

separately. The standard setting is �Reset the output".

2. Commissioning


The valves of the CPV Direct basic unit and the outputs of the

modules in the extension are set with separate parameters:

Parameter �Fault Action, main unit"

With this 16−bit parameter you can determine whether each

output is to freeze the current status or assume a certain

output status (0/1) in Fault mode.

Parameter

value

Meaning

0 The output is set to a certain output status (0 or 1).

The output status is defined with the parameter

�Fault Value, main unit".

Reaction of the outputs in the Idle mode

The Idle mode is assumed by the slave after request by the

master or scanner. The following applies in this status:

� Inputs are transmitted

� Outputs of the slaves are no longer updated.

In the Idle mode, the outputs for the valve control and the

outputs of the output module can assume one of the follow�

ing states:

� Reset the output

� Set the output

� Freeze the current status of the output.

You can determine the status to be assumed for each output

separately. The standard setting is �Reset the output".

The valves of the CPV Direct basic unit and the outputs of the

modules in the extension are set with separate parameters:
