1.1 General notes on installation

Warning

Sudden unexpected movement of the connected actuators
and uncontrolled movements of loose tubing can cause
injury to human beings or damage to property.

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

– the compressed air supply
– the operating voltage supply for the internal logics
– the load voltage supply to the valves.

You will thereby avoid undefined switching states of the
electronic components.

Caution

The electronic components may be damaged if they are
not handled correctly.

– Observe the handling specifications for electrostatically

sensitive components.

– Do not touch the electrical contacts of the components.

1.3 Connecting to the field bus

1.3.1 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 attenuations.
Causes of the transmission faults 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 on the type of cable to be used.

Use a twisted, screened 4-core cable for connecting the field
bus. The bus interface is supplied with power via the field bus
cable.

If the Festo field bus plug is used, a cable diameter of
5…8mmor7…10mmispermitted.

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. Note the relevant regulations in:
IEC/DIN EN 60204-1.

1.3.2 Field bus baud rate and field bus length

The maximum permitted field bus length depends on the
baud rate used. Detailed information can be found in the
manuals for your control system.

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 cable.

Information on setting the baud rate can be found in
section 1.2.3.

1.3.3 Information on connecting the field bus

The field bus interface on the CPV Direct serves for providing
and continuing the field bus cable. The feld bus connection
can be exchanged and has been designed as:

– a 9-pin Sub-D plug

– an M12 adapter

– a screw terminal adapter.

Caution

• Make sure the polarity is correct when you connect the

field bus interface and the power supply for the bus
interface/internal logics.

• Connect the screening/shield.

Note

Bus slaves have different tolerances in respect of 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 9 on the Sub-D plug or pin 2 on the M12
adapter and pin 5 on the screw terminal adapter):
V

= 30.0 V

max

V

= 11.0 V

1.5.2 Selecting the power unit

Warning

• In order to provide the electric power supply, use only

PELV circuits as per IEC/DIN EN 60204-1 (Protective
Extra-Low Voltage, PELV).
T ake into account also the general requirements for
PELV circuits as per IEC/DIN EN 60204-1.

• Use only power packs which guarantee reliable electri-

cal isolation of the operating voltage as per IEC/DIN
EN 60204-1.

By the use of PELV power units, protection against electric
shock (protection against direct and indirect contact) is
guaranteed in accordance with IEC/DIN EN 60204-1
(electrical equipment of machines, general requirements).

The current requirement of a CPI/CP system depends on the
number of CPI/CP modules and valve coils.
Recommendation:

• Use closed-loop controlled power units.

• When selecting the power unit, check that it provides

sufficient output. If necessary, calculate the total current
requirement 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” may lead to 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 section for the values.

• Connect the power supply to the 4-pin M12 plug

(Fig. 1/1).

• Observe the tolerance when connecting the 24 V load

voltage at pin 2: 20.4 … 26.4 V DC. Check the 24 V operat­ing voltage of the valves whilst 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

Check your EMERGENCY STOP circuit in order to ascertain
the measures 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.

Duetoenergystoredintheinputcircuitryofvalveter­minals, there may be a delayed reaction of the valves when
the load voltage is switched off.

T ake 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”.

1.7 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 yet connect the CPV Direct to a higher-order
controller for preparing commissioning.

You will thus avoid addressing faults which may occur in
variousfieldbussystemswhenaddressrangesaremodi­fied 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.

1-38

Festo P.BE-CPV-CO3-EN en 1201a

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 fitted 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 addresssing. 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 light up, the
CPI system is prepared for commissioning. You can now com­mission the CPI system.

Festo P.BE-CPV-CO3-EN en 1201a

1-39

1. Installation

Saving the string
assignment

The desired string assignment is generated and saved for
commissioning. In this way the connected CPI/CP modules
are assigned with the relevant addresses.

Save the string assignment 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

1.8 Switching-on reaction of the CPI system

When the power supply is switched on, the CPV Direct
ascertains automatically the current string assignment. It also
ascertains which CPI/CP modules are connected to the string
extension.

Ifthecurrentassignmentisthesameasthesaved
assignment, the CPV Direct will switch automatically to the
ready-to-operate status.
The PS/PL LEDs of the CPV Direct as well as the status LEDs
on the connected CPI/CP modules light up.

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.

Warning

Undesired activation of actuators
An incorrect status of the valves and outputs can lead to

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, 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 on 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 with the CPV Direct again.

3. Switch on the power supply for the CPV Direct again.

1.9.2 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 an individual 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 sources of energy:
– 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 ofthesametype.

5. Now connect the new module ofthesametypeto the
same string.

6. In the case of CPI/CP output modules and CP valve
terminals:
Switch on the operating voltage supply or the
compressed air supply again.

7. Switch on the power supply for the CPV Direct again.

8. Check the addresses of the CPI system.

2.2.1 General information on CANopen

CANopen devices have an object directory which makes all
important slave parameters accessible in a standardized
manner. A CANopen system is configured mainly by access to
the object directory of the individual slaves. The access
mechanism is provided by Service Data Objects (SDO).

There are two different communication mechanisms in a
CANopen system.

The P

rocess Data Objects (PDO) serve for the fast transfer of

processing data and are transmitted by simple CAN mess­ages without protocol overhead. Process Data Objects can be
transmitted event-controlled, synchronous to a system pulse
sequence or on demand.

The S

ervice Data Objects (SDO) form a point-to-point connec-

tion and permit access to every entry in the object directory
of a node.

2.3.5 Reaction to network communication faults

You can parametrize the reaction of the valves and any exist­ing outputs if a fault occurs. All valves/outputs are reset as
standard when the following faults and operating states occur
as soon as Node guard, Heart beat are activated via the con­figuration:

– Communication faults (Node guard, Heart beat)

– Transitio n from operational to pre-operational or stopped

The status of the valves/outputs can be modified via indices
6206 and 6207 (Default Output Mode, Error State Output)
(see section B.1.4).

The general reaction of the valve terminal to faults (communi­cation faults, faults on the input or output module and faults
on the CPI/CP string) can be parametrized via Index 1029.

Default setting via Index 1029 (see section B.1):

– Communication faults as well as input/output faults lead

to the pre-operational status.

– CPI/CP faults remain in the current status.

Warning

• Make sure that valves and outputs are reset when the

faults named occur.

Dangerous situations may arise if the valves and outputs
are not reset.

Note here the example C.1.3. in the appendix.

2.4 Tool change configuration

With the string configuration in the tool change configuration,
you can commission modules on the CPI extension connec­tion without a 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

In the tool change configuration, the system does not
check which modules are actually connected. After modifi­cation to the string assignment, evaluation of input signals
may appear to be incorrect if inputs, which are no longer in
the new string assignment, are read. The current CP string
extension can be ascertained via Object 3100.2-5.

After modification to the string assignment (e.g. with fewer
modules): Make sure that the controller processes only the
addresses of the modules actually connected to the CP
string. The same applies for outputs.

Addressing and function With the tool change configuration, the maximum possible

32 inputs and 32 outputs will be assigned in the CPI string
extension, irrespective of whether these are used or not. The
addresses are assigned without gaps, module after module
in ascending sequence. Please take this into account when
programming the controller.

3.1.3 Status display of the valve solenoid coils

There is a yellow LED for every valve solenoid coil
(see Tab . 3/6). This LED indicates the switching status of
the valve solenoid coil.

Note

The LEDs indicate the signal states only if there are valve
coils at the relevant valve locations. For this purpose the
load voltage must lie within the permitted tolerance.

3.2.1 Composition of the Emergency Message

The CPV Direct sends an Emergency Message in the event
of a fault. Parallel to this, the pre-defined error field
(Index 1003) will be written with the appropriate fault
message from:

– Byte 0 and byte 1 of the Manufacturer Status Register

(Index 1002) (corresponds to bytes 3 and 4 of the
emergency object)

– Error code as per DS301

The existing faults will each be shifted by one position in the
pre-defined error field (see section B.1, Index 1003, Subin­dices 1 … A).

Bytes 3 to 7 of the Emergency Message correspond to the
Manufacturer specific error field and contain device-typical
error messages.

3. Diagnosis and error treatment

3.4 Short circuit/overload

Detailed information on input and output modules can be
found in the manual “CP modules electronics”.

3.4.1 Output module

If there is 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 fast

– the bit Short circuit/overload (Index 1002, byte 1, bit 2)

will be set to “1”.

Note

The outputs cannot be used again until the short circuit or
overload has been eliminated and the fault deleted.

Deleting faults

You can delete (quit) the fault by resetting all 8 outputs. You
can do this in one of the following ways:

Options

• Set all the outputs of the output module t o “0” (RESET)

or

• Interrupt briefly the operating voltage for the

CP system

Explanation

– Manually or automatically in the

program

– All outputs on the CP system will be

reset automatically

T ab. 3/14: Possibilities of deleting the fault

The outputs can then be used again. If the short circuit/
overload still exists, the outputs will be switched off again.

3-18

Festo P.BE-CPV-CO3-EN en 1201a

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 there is a diagnostic LED on the output module, it will

light up, otherwise the green LED will flash.

–ThefaultbitV

(Index 1002, byte 1, bit 4) will be set

sen

to “1”.

Note

The inputs cannot be used again until the short circuit or
overload has been eliminated and the fault quitted.

Deleting faults

In order to delete the fault, proceed as follows:

– Interrupt briefly 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.
