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.

1.4 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.

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.

1.5.3 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
1−30 Festo P.BE−CP−DN2−EN en 0503a
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".

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.

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.

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.

2.2.3 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.

2.2.5 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".

3.2 Error search when bus is started
A deviation in the actual extension of your CPV Direct from
the extension set in the switch module can lead to problems
when the system is started. Please refer in this case to
chapter 1.6. The following table shows the reaction:

3.3 Reaction to faults in the control system
The reaction of the outputs to control faults or communica�
tion faults can be set with the parameters:
� �Fault Value" and �Fault Action"
� �Idle Value" and �Idle Action".
The standard setting is �Reset the output".
Further information on parametrizing can be found in chapter
2.2.5.
Please note
If the outputs are reset in the event of a PLC stop, field bus
interruption or field bus fault, please observe the follow�
ing:
� Single−solenoid valves move to the basic position.
� Double−solenoid valves remain in the current position.
� Mid−position valves move to the mid−position (depend�
ing on valve type: pressurized, exhausted or blocked).

3.5 Short circuit/overload
Detailed information on input and output modules can be
found in the manual �CP modules electronics".
3.5.1 Output module
In the event of a short circuit or overload:
� all the digital outputs of an output module will be
switched off,
� the green LED �Diag" on the output module will flash
quickly,
� bit 2 (short circuit/overload) in the Device Status byte will
be set to logic �1".
Please note
The outputs cannot be used again until the short circuit or
overload has been eliminated and the error deleted.
Deleting the error
You can delete the error by resetting all eight outputs. You
can select one of the following possibilities:
Possibilities Explanation
S Set all the outputs of the output module tological �0" (RESET)
or
� Manually or automatically in the program
or
S briefly interrupt the CP connection at the CPoutput module
or
� Outputs on the output module will be reset
automatically
or
S briefly interrupt the operating voltage for theCP system
� All outputs of the CP system will be reset auto�
matically

The outputs can then be used again. If the short circuit/over�
load still exists, the outputs will be switched off again.
3.5.2 Sensor supply at an input module
If there is a short circuit, overload or voltage fault in the sen�
sor supply:
� the sensor supply for all inputs of the module will be
switched off,
� the green LED �Diag" on the input module will flash
quickly,
� error bit Vsen (bit 4 in the Device Status byte) will be set to
logic �1".
Please note
The outputs cannot be used again until the short circuit or
overload has been eliminated and theerror deleted.
Deleting the error/short circuit/overload
You can delete the error in one of the following ways:
S Briefly interrupt the CP connection at the CP input module
or
S briefly interrupt the operating voltage of the CP system onthe CPV Direct.
The inputs can then be scanned again. If the short circuit/
overload still exists, the error will be shown again.
Module CP−E16−M8−Z:
The short circuit/overload will be reset automatically and the
voltage will be switched on again.
