Connecting to the field bus
Field bus cable
Note
If installation has not been carried out correctly and if high
baud rates are used, data transmission errors may occur
as a result of signal reflections and attenuation.
Causes of the transmission errors can be:
– missing or incorrect terminating resistor
– incorrect screening/shield connection
– branch lines too long
– transmission over long distances
– unsuitable cables.
Observe the cable specifications. Refer to your controller
manual for information about the type of cable to be used.
Use a twisted, screened 5-core cable for connecting the field
bus. The bus interface is supplied with power via the field bus
cable.
Alternatively, you can use ready made bus cables from other
manufacturers (see also appendix A, Accessories).
Note
If the valve terminal is fitted into a moving part of a
machine, the field bus cable on the moving part must be
provided with strain relief. Also note the relevant
regulations in: IEC/DIN EN 60204-1.

The maximum permitted length of the branch line depends on
the total length of the branch lines and the baud rate.
Note
• Refer to the manuals for your control system or bus
interface in order to ascertain which T-adapter you
should use and the maximum branch line length which is
permitted for your controller.
• Take into account also the sum of the branch line lengths
when calculating the maximum permitted length of the

Field bus interface
The field bus interface on the CPV Direct is used for the
supply line and continuation of the field bus line. The field
bus connection is exchangeable and can be in the form of:
–
9-pin Sub-D connector,
–
Micro style connection (2 x M12)
–
Open style connection (terminal strip).
Caution
• Make sure the polarity is correct when you connect the
field bus interface and the power supply for the bus
interface/internal logic.
• Connect the screening/shield.
Note
Bus slaves have different tolerances in respect to the interface supply, depending on the manufacturer. Note this
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:
Avoid long distances between the bus interfaces / logic supply and the CPV Direct. Place the power unit approximately in
the centre of the bus.

Bus termination with terminating resistors
Note
Fit a bus termination to both ends of a bus segment. This
also applies if the bus circuit or bus interface is at the
beginning of the bus cable.
If the CPV valve terminal is at the end of the field bus system,
a bus termination will be required.
If you use T-adapters, we recommend that you install the
terminating resistor at the unused output of the T-adapter.
Recommendation:
For the bus termination fit a terminating resistor (120 Ω,
0.25 W) between the connections for CAN_L and CAN_H.

Power supply
Cable for power supply
•
Use a power supply cable with sufficient cross-sectional
area.
•
Avoid long distances between the power unit and the CPV
valve terminal. Long cables reduce the voltage supplied
by the power unit.
•
If necessary calculate the suitable cross-sectional area
and the maximum permitted cable length.
The power supply connection is in the form of a plug. The pin
assignment of the plug can be found on the following pages.
Use plugs from the Festo range for connecting the power
supply in accordance with the outer diameter of the cables
used (see appendix A.3).

the “safety I/O module” may result in unexpected reactions of the valve terminal.
• Make sure that switch-on test pulses are reliably
suppressed or switched off.
Current consumption depends on the type of valve terminal.
Please refer to the Pneumatics manual, P.BE-CPV-... and the
previous chapter for the values.
•
Connect the power supply to the 4-pole M12 connector
(Fig. 1/1).
•
Observe the tolerance with the connection for the 24 V
load voltage at pin2: DC 20.4 V … 26.4 V. Check the 24 V
load voltage of the valves while the system is operating.
Caution
Protect the load voltage of the CPV valve coils with a
max. 2 A external fuse.
In this way you can avoid functional damage to the
CPV Direct in the event of a short circuit.

Note
During the course of your EMERGENCY STOP design, check
which measures are necessary for switching your machine/
system into a safe state in the event of an EMERGENCY
STOP:
– Switching off the load voltage for the valves and output
modules in the secondary circuit of the power unit.
– Switching off the compressed air supply for the valve
terminal.
Due to energy stored in the input circuitry of valve terminals, there may be a delayed reaction of the valves when
the load voltage is switched off.
Take this into consideration, e.g. as follows:
– by using an input signal in the controller for checking
whether the load voltage has been switched off.
– by blocking the control signal for the valves by locking
the output signal with the input signal “Load voltage”.

Potential equalisation
The CPV valve terminal has 2 earth connections for potential
equalisation:
–
on the power supply connection
–
on the end plate.
Note
• Always connect the earth potential to pin 4 of the power
supply connection.
• Connect the earth connection of the end plate with low
impedance (short cable with large cross-sectional area)
to the earth potential.
• By means of low-impedance connections, make sure
that the case of the valve terminal and the earth connection at pin 4 have the same potential and that there are
no equalising currents.
In this way, you will avoid interference caused by electromagnetic influences.

Rules for extending the CPI system
The CPI system supports a different number of modules per
CP string, depending on the type of CP master and on the
connected CPI/CP modules.
The CPV Direct is a CPI master.
Modules can be placed in two different groups:
–
CPI modules (with extended functions)
–
CP modules (without extended functions)
Rules and properties
CPI system
– Max. 4 modules on the CP string
– Max. 32 inputs and 32 outputs (per CP string)
– The sequence of the modules within the CP string can be in any order
CPI master
A mixture of CPI / CP modules is possible on CPI masters:
– Only one CP input module is possible at the end of a string
– Only one CP valve terminal 2) or one CP output module 2) is possible per CP string.
– “Unused” locations on the CP string can be “filled” with CPI modules 1)
CPI modules
Modules always have an incoming and continuing interface to all CPI modules (input
modules, output modules) and valve terminals with CPI connection

Preparing the CPI system for commissioning
This section is only relevant for you if you have connected
CPI/CP modules to the CPI extension connection.
Note
Do not connect the CPV Direct to a higher-order controller
yet for preparing the commissioning.
You will thus avoid addressing faults which may occur in
various field bus systems when address ranges are modified during operation.
1.7.1
Checking the CP strings
Preparations
Before commissioning a CPV Direct with CPI extensions, you
should first prepare each individual CPI system for commissioning.
Proceed as follows:
1. Check the pneumatic tubing of the valve terminals with
the aid of the manual override (see pneumatics manual).
2. Check the complete electric circuitry of the CPI system.
3. Save the current string assignment of the CPI system as the
nominal assignment, as described in section 1.7.2.

1. Installation
1.7.2
Saving the string assignment
Warning
Be very careful if the string assignment of your CPI system
is modified at a later stage:
• After saving the string assignment, check the address
assignments of your CPI system before starting user
programs.
You will then avoid addressing faults in the case of incorrectly installed CPI/CP modules.
String assignment
The CPV Direct saves the type and the sequence of the
connected CPI/CP modules for the CP string (string
assignment).
The saved string assignment enables the CPV Direct to avoid
faults in connecting, and thus addressing. It checks automatically to see if the current string assignment is the same
as the saved assignment. A distinction is made here between the following test phases:
–
testing during the start-up phase (see section 1.8)
–
testing during operation (see section 1.9).
When the status LEDs on all the CPI/CP modules are lit, the
CPI system is prepared for commissioning. You can now
commission the CPI system.
1-38
Festo P.BE-CPV-DN3-EN en 1201a
1. Installation
Saving the string
assignment
The desired string assignment is generated and saved for
commissioning. In this way the appropriate addresses are
assigned to the connected CPI/CP modules.
Save the string assignments as follows:
1. Leave the power supply for the CPV Direct switched off for
the time being.
2. Make sure that the CPI cables are fastened properly with
the union nut.
3. Switch on the power supply for the CPV Direct and, if
necessary, for the CPI/CP modules with load voltage
connection.
The fault LED P on the CPV Direct will flash if CPI/CP
modules are connected or if the string assignment is
modified.
4. Use a small screwdriver or similar tool to press the SAVE
button for at least 1 s (see section Fig. 1/3).
This will save the current string assignment as the nominal string assignment in the CPV Direct.
The fault LED Pno longer flashes.
The status LEDs of all the recognised CPI/CP modules
light.
Note
After saving the string assignment, check the address
assignments of your CPI system before starting user
programs.

1.8
Switching-on reaction of the CPI system
When the power supply is switched on, the CPV Direct ascertains the current string assignment automatically. It also
ascertains which CPI/CP modules are connected to the string
extension.
If the current assignment is the same as the saved assignment, the CPV Direct will switch automatically to the readyto-operate status.
The PS/PL LEDs of the CPV Direct as well as the status LEDs
on the connected CPI/CP modules light.
If the current assignment is not the same as the saved assignment, the fault LED P on the CPV Direct will flash. In this
case the CPI system is not ready to operate.
You then have the following possibilities of restoring the
readiness to operate:
–
Eliminate assignment faults manually or replace individual CPI modules (see section 1.9).
–
Save the current assignment as the nominal assignment
(see section 1.7.2).
Detailed instructions on diagnosing the CPV Direct using the
LEDs can be found in section 3.1.

Reaction of the CPI system to faults in operation
Warning
Undesired activation of actuators
An incorrect status of the valves and outputs can result in
dangerous situations.
• Make sure that valves and outputs are put into a safe
state when faults occur.
If there is a fault on the CP string during operation, e. g. due
to cable fracture, etc., this will be displayed on the CPV Direct
by the diagnostic LED of the string extension (P). The status
LED on the relevant module goes out. All modules working
without faults remain ready to operate.
Detailed instructions for diagnosing the CPV Direct using the
LEDs can be found in section 3.1.
1.9.1
Eliminating assignment faults
In order to eliminate assignment or connection faults of the
CPI system:
1. Switch off the power supply for the CPV Direct.
2. Restore the saved assignment by connecting the
appropriate CPI/CP modules to the CPV Direct again.
3. Switch on the power supply for the CPV Direct again.

Replacing CPI/CP modules
Note
Replacing a CPI/CP module with a CPI/CP module of a
different type or replacing several CPI/CP modules will
require new commissioning and new saving of the string
assignment (see section 1.7).
In order to replace a single module, proceed as follows:
1. Switch off the power supply for the CPV Direct.
2. In the case of CPI/CP output modules and valve terminals
on the CP string concerned:
Switch off the following energy sources:
– the compressed air supply to the valve terminal
– the operating voltage supply for the CPI/CP output
module.
3. Disconnect all connecting cables and, if necessary, also
the tubing.
4. Connect all the cables and, if applicable, the tubing with
the new module of the same type.
5. Now connect the new module of the same type to the
same string.
6. In the case of CPI/CP output modules and CP valve
terminals:
Switch on the operating voltage supply and the
compressed air supply again.
7. Switch on the power supply for the CPV Direct again.
8. Check the addresses of the CPI system.

Tool change configuration
With the string configuration in the tool change configuration
you can put CPI expansion connection modules into operation
without new configuration. In the tool change configuration,
pressing the SAVE button is not necessary.
The tool change configuration is useful if various CPI string
extensions are connected in turn to the CPV Direct during
operation.
Note
The system does not check in the tool change configuration which modules are actually connected. After changing the string assignment, evaluation of input signals can
appear to be defective if inputs are read which are no
longer present in the string assignment.
After changing the string assignment (e.g. with fewer
modules): Ensure that only the addresses of the modules
actually connected to the CP string are processed by the
controller. The same applies to outputs. Note the example
in Tab. 2/5.
Addressing and function

Bus configuration
Note
The Festo valve terminal type CPV...-GE-DN3-8 can be used
on all DeviceNet masters. This chapter describes configuration and commissioning using the example of the AllenBradley controllers.
General instructions for commissioning
Please note the following special features when using the CPV
valve terminal on the DeviceNet:
–
The I/O addresses of all recognised DeviceNet slaves can
be freely assigned as M-file addresses or as discrete I/Os
in the Scanlist.
–
The address assignment of a network slave is usually
carried out in ascending sequence.
–
The input and output addresses can be assigned independently of each other.
Note
Assign the I/O addresses of the network slaves so that
there is sufficient reserve for later extensions.
The following sections contain generally applicable instructions for configuring a valve terminal on the DeviceNet.
Detailed information can be found in the documentation or
the Help for the configuration program you are using.

Switching on the power supply
Note
Please also observe the switching-on instructions in the
manual for your PLC.
After switching on, the controller automatically performs a
comparison between the target and actual configurations. It
is important for this configuration run that:
•
the specifications for the field bus configuration are complete and correct,
•
the power supplies for the programmable logic controller
and for the field bus slaves are switched on either simultaneously or in the sequence indicated below.
Please note the following when switching on the power
supply:
Common supply
Common power supply for the control system and all field
bus slaves via a central power unit or a central switch.
Separate supply
Switch on the separate power supplies of the controller
system and field bus slaves in the following order:
1. operating voltage power supply of all field bus slaves,
2. operating voltage power supply for the controller.

Configuring DeviceNet slave features (EDS)
When you commission a new DeviceNet slave the first time,
you must inform your configuration program about certain
features of the slave.
The features of the various slaves are usually managed 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”:
–
Standard EDS
–
Modular EDS
–
Enter slave properties manually (only when using the
parameter settings set at the factory).
Note
Only one variant (Standard EDS or Modular EDS) must be
loaded in the RSNetWorx (or in other tools) software
program. The old variant is overwritten when a new EDS
variant is loaded into the software.

Remarks about configuration on the DeviceNet
When the slave features have been configured (e.g. by installation of the EDS file), the following steps are required for
parameterisation, depending on the configuration program.
1. Add the slave to the project / network (online or offline).
If the slave is added e.g. offline, it will be selected from
the slave list and added to the network.
2. Assign the slave to a scanner. A network can contain
several scanners. The slave must be assigned to a
scanner.
3. Define the I/O parameters of the slave. The following
entries are required here:
•
Number of I/O bytes to be transferred. For the
CPV Direct, the number depends on the connected
extensions (see section 1.6):
– 2 input bytes occupied
– 2 or 4 output bytes occupied.
•
Specification of the communication type.
The following applies for the CPV Direct:
– “Polled communication”
or
– “Change of State / Cyclic”
In addition to these communication connections, a
“Strobed I/O” connection must be used in each case
for the diagnostics.
Note
The specification of the diagnostics mode must correspond
to the setting of the 2-element DIL switch (see section
1.2.5).

The condition counter automatically counts the number of
valve actuations. With the parameter “Reset Condition
Counter Value” you can reset the counter value (“Condition
Counter Value”) at any time. The reset parameter works
positive-edge orientated, only the transition from value “0”
to value “1” will reset the “Condition Counter Value”.
With the parameter “Condition Counter Preselect” you can
define a limit value for each counter. If this limit value is
exceeded, the parameter “Condition Counter Compare” will
be set. In addition to the individual counters compare Status,
all 16 comparison results are represented together in the
parameter Counter Preselect Compare 1 … 16.”
With the value “0” in the “Condition Counter Preselect”, the
compare function becomes inactive (standard setting).

Automatic parameterisation via the scanner (ADR)
For Modular EDS, you need RSNetWorx Version 5 or later for
automatic parameterisation.
In order to force automatic parameterisation when a
CPV Direct is replaced or after Power on:
1. Double click on the scanner in the network. Change to the
“ADR” tab.
2. Select the CPV Direct from “Available Devices”.
3. Under “ADR Settings”, activate the “Configuration
Recovery” setting.
The scanner now automatically loads the specified parameters into the CPV Direct before it exchanges I/O data with
the CPV Direct.
Note
Without ADR, the parameters are stored locally in the valve
terminal.

Parameterisation via the user program (Explicit Message)
Program-controlled access to parameters is made via the
“Explicit Message” programming. The addresses of the
DeviceNet object model necessary for this can be found in
appendix B of this manual.
Information about programming can be found in the manual
for your controller.

Checklist for commissioning the CPV Direct on DeviceNet
Observance of the following points helps you to avoid errors
during commissioning the CPV Direct on DeviceNet.
2-48
•
Check the DIL switch settings before using the CPV Direct.
•
Note the instructions for switching on the power supply in
section 2.2.1.
•
Check the configured address range (process data and
assigned input and output bytes). Test the inputs and
outputs if necessary.
•
Check the address assignment of the inputs and outputs,
particularly for the tool change configuration.
•
Ensure that the desired parameterisation of the CPV Direct
in the start-up phase or after field bus interruptions is
restored by the interface module. After a replacement,the
new CPV Direct will therefore also be operated with the
desired parameter settings.
•
Check the parameterisation, for example using the
configuration program.

Error handling
With the following faults, the reaction of the CPI system
depends on the configured reaction of the master module:
–
telegram failure
–
The master has stopped
–
interruption in the bus cable.
Depending on the parameterisation or configuration, the
outputs (valves, electrical outputs) will be switched off
(factory setting), switched on or retain their status.
Warning
• Ensure that valves and outputs are put into a safe state
if the faults named occur.
An incorrect status of the valves and outputs can result in
dangerous situations.
Note
Please note the following if the outputs are reset after
PLC stop, field bus interruption or fault:
– Single-solenoid valves move to the basic position.
– Double-solenoid valves remain in the current position.
– Mid-position valves move to the mid-position (depending on valve type: pressurised, exhausted or blocked).

Short circuit/overload
Detailed information about input and output modules can be
found in the manual “CP modules electronics” and “CPI-CL
modules, CPI-EL modules”.
3.4.1 Output module
If there is a short circuit or overload:
–
all digital outputs of an output module will be switched off
–
if present, the diagnostic LED on the output module will
light, otherwise the green LED will flash
–
the short-circuit/overload bit in the DeviceNet diagnostics
object (object class 103d) will be set.
Note
The outputs cannot be used again until the short circuit or
overload has been eliminated and the fault cleared.
Clearing faults
You clear the faults by resetting all 8 outputs. You can do this
in one of the following ways:
Options
Explanation
• Set all the outputs of the output module to
– Manually or automatically in the program
logical “0” (RESET)
• Briefly interrupt the CP connection on the
CP output module
• Briefly interrupt the operating voltage for the
CPI system
– The outputs on the output module will be
reset automatically
– All outputs on the CPI system will be reset
automatically
Tab. 3/10:
Possibilities for clearing the error
The outputs can then be used again. If the short circuit/
overload still exists, the outputs will be switched off again.

3. Diagnosis and error treatment
3.4.2 Sensor supply on one input module
If there is a short circuit, overload or voltage fault in the
sensor supply:
–
the sensor supply for all inputs of the module will be
switched off
–
if present, the diagnostic LED on the output module will
light, otherwise the green LED will flash
–
the Vsen bit in the DeviceNet diagnostics object
(object class 103d) will be set.
Note
The inputs cannot be used again until the short circuit or
overload has been eliminated and the fault cleared.
Clearing faults
You have the following alternatives for clearing faults:
1. Briefly interrupt the CP connection on the CP input
module.
2. Briefly interrupt the operating voltage for the CPI system
on the CPV Direct.
The inputs can then be scanned again. If the short circuit/
overload still exists, the fault will be shown again.
Module CP-E16-M8-Z:
The short circuit/overload will be reset automatically and the
voltage will switched on again.

Compatibility of the CPV...-GE-DN3-8 with earlier products
If you wish to use the CPV Direct type CPV...-GE-DN3-8 as a
replacement for the earlier variant type CPV...-GE-DN2-8, you
must adapt the network configuration.
The CPV-DN3 is different from the CPV-DN2 as regards
–
product type
–
software version
–
diagnostic and status information.
The position and length of the physical I/O data are identical
and can be retained.
You can use the addresses of the 8 status bits of the
CPV...-DN2 for the status byte of the CPV...-DN3.
You can adapt the settings for the configuration in your
configuration software as follows:
1. Remove the existing slave from the configuration.
2. Install the new EDS file in your configuration software.
3. Add the new slave CPV...-DN3 to the project/network.
4. Assign the address of the previous slave to the new one.

B.1.12 Structure of the External Modules Identifier (Modular EDS Query)
The module types and their I/O configurations are stored in
the External Modules Identifier.
The CPV-DN3 is defined as a system with 6 slots. Slot 0
always contains the Communication Adapter which describes
all global objects. The slots 1 … 5 are module-related.
The CPV-DN3 is always configured on slot 1.
The CPI/CP modules are configured on slots 2 … 5.
The slot identifier is 2 bytes.
