1. System summary – CPI system

A CPI system consists of individual modules which are con­nected to each other by means of CPI cables. In this way it is
possible to decentralise the configuration of the CPI modules.
The compact CP valve terminals and I/O modules can be
mounted very close to the cylinders to be controlled. This
enables short compressed air lines to be used.

System losses can be minimized if short compressed air
tubing is used and the times required for pressurising and
exhausting the tubing can be reduced.

This enables smaller valves with sufficient flow to be used,
thereby helping to reduce costs.

1.1.2 Variants and extension rules for the CPI-/CP system

Modules can be divided into two groups:

– CPI modules (extended functions)
– CP modules (no extended functions)

Tab. 1/3 shows the number of supported modules and rules
dependent on the type of the master and the CPI/CP mod­ules.

Rules and properties

CPI system – Max. 4 modules on the CP string

– Max. 32 inputs and 32 outputs per CP string

CPI modules – There is an incoming and continuing interface on all CPI modules and valve

terminals

– Any sequence of the CPI modules/valve terminals within the CP string

CP modules – There is an incoming and continuing interface on CP output modules and CP

valve terminals

– Only incoming interface at CP input modules. They can therefore only be

placed at the end of a CP string.

CPI/CP master The CPX-CP interface and the CPV Direct are CPI masters.

A mixture of CPI/CP modules is possible on CPI masters:
– Only one CP input module is possible at the end of a string
– Per CP string, only one CP valve terminal
– “Unused” locations on the CP string can be “filled” with CPI modules2).

Festo P.BE-CPX-CP-EN en 1211b

Note

Independent of the type of CPI/CP modules, not more than
32 inputs and 32 outputs may be connected (sum of all
modules on a CP string).

That is, a CP string can be extended with a maximum of 2
CP valve terminals with extended functions, since they
always occupy 16 output addresses.

1.2 CPI system with the CPX-CP interface

The CPX-CP interface supports CPI systems with extended
functions. CPI systems with CP modules with extended
functions are distinguished by the following features:

– moreI/Osperstringarepossible(max.32I/32O)

– up to 4 CPI/CP modules are possible

– modules can be in any order.

The CPX-CP interface, in the capacity of technology module
(also termed function module), assigns I/O addresses in the
CPX terminal. The number of addresses assigned depends
on:

– the field bus node or FEC used and the operating mode of

the CPX terminal,

– the saved configuration (string assignment).

Address assignment is carried out as follows:

Field bus node/FEC

CPX field bus node with Remote I/O
operating mode, e.g.:

–

CPX-FB11, DeviceNet

–

CPX-FB13, PROFIBUS

–

CPX-FB14, CANopen

–

CPX-FB23, CC-Link

CPX front end controller with Stand Alone
or Remote Controller operating mode:

–

CPX-FEC

CPX field bus node for Interbus with
operating mode Remote I/O, e.g.:

–

Size of the assigned ad­dress range

The following rules apply to the address range occupied by
the CPX-CP interface ( Tab. 1/6):

– The size of the assigned address range depends on the

number of the last string used.

– The assignment for inputs is independent of the assign-

ment for outputs.

– Each string on the CP interface has an address range of

32 bits for inputs and 32 bits for outputs at its disposal.

Unused address range Unused address range is reserved for extensions.

1.2.2 Address assignment

The assignment of the addresses of the CPI/CP modules
depends on the CPX field bus node or CPX-FEC used. The
following representation applies to the field bus nodes (e.g.
CPX-FB13) as well as for the Front End Controller CPX-FEC, but
not for Interbus field bus nodes. The assignment for Interbus
field bus nodes (e.g. CPX-FB6) can be found in appendix B.1.

Address assignment of the individual modules takes places
according to the following rules:

– A CP interface provides four strings with a total of

128 input addresses and 128 output addresses.

– A used string occupies 32 input addresses and 32 output

addresses.

– The addresses are assigned fixed to the individual CP

strings and CPI modules in ascending order.

String

Input addresses Output addresses

number

1 I0 ... I31 O0 ... O31

2 I32 ... I63 O32 ... O63

3 I64 ... I95 O64 ... O95

4 I96 ... I127 O96 ... O127

– Address assignment of the individual modules is there-

fore determined by the string to which they are connected
and by the number of I/Os the existing modules occupy
on the string.

Festo P.BE-CPX-CP-EN en 1211b

– Unused address range (due to modules not being

available) remains reserved for later CPI extensions.

The diagram below shows as an example the address
assignment of a CPI system.

2.2 CPI connections

Note

Operative malfunction due to impermissible cabling.

•

For connecting the CPI/CP modules to the CP string,
use only the special CPI/CP cables from Festo
( www.festo.com/catalogue).

•

Observe that the total cable length on a string must not
exceed 10 m.

•

Dependent on the CPI/CP modules and CPI/CP cables
used as well as the current consumption, the
permissible modules and string length per CP st ring may
be limited ( section 2.2.1).

•

Observe the maximum permissible current consumption

per CP string, ( section 2.3.2).
In this way, you can avoid:
– Errors in data exchange between the CPX-CP interface

and the connected modules.

2.2.2 Connecting CP strings

CP connections There are four CPI connections for the CP strings on the

CPX-CP interface (X1 ... X4).

CPI/CP modules can be connected to each CPI connection
according to the rules described in section 1.2 .

Connecting CP modules

1. Check which address range is intended for the CPI/CP
module ( section 1.2).

2. Connect the modules with the CPI/CP cables to the string
which makes this address range available.

3. Fasten the plug and socket of the CPI/CP cable with the
union nut. In this way the electrical contact is guaranteed.

4. Use the identification labels (type IBS 6x10 or IBS 9x20)
to indicate the string to which the module is connected.
In this way you can avoid confusion during later repair
and maintenance work.

2.3 Connecting the power supply

Take the following aspects into consideration when installing
a CPI system with the CPX-CP interface:

– Power supply ( section 2.3.1)

– Current consumption ( section 2.3.2)

– Formation of power zones ( section 2.3.3).

Note

It is imperative that you observe the notes in section 2.3.3
when forming power zones in the CPX terminal by means
of several manifold blocks with power supply.

Recommendation:

• Provide the load voltage for the valve coils and, if necess­ary, for the outputs separately if you wish to implem ent
an EMERGENCY STOP function.

Note

Check whether pressure switch-off is also necessary for an
EMERGENCY STOP function on your machine/system.

Note

Observe the notes on earthing the CPI/CP modules in the
manual for the relevant module.

2.3.2 Ascertaining the current consumption

The current consumption of a CPÎ system depends on the
number and type of the CPI modules connected.

Recommendation:

• Use a closed-loop controlled power unit.

• When selecting the power unit, check that it has sufficient
output. Calculate the total current consumption, if
necessary.

Calculation Tab. 2/5 and Tab. 2/7 show how to calculate the total current

consumption for a CPI system. Please refer to the relevant
technical specifications for the current consumption of the
CP valve terminals and the CPI/CP modules.

Note

Select a power unit which provides sufficient output for
later extensions to the CPI system.

If you are using CP output modules with a separa te load
voltage connection, take into account the appropriate current
consumption when selecting a power unit.

Observe the notes on selecting the power unit in the
CPX system manual.

Do not yet connect the CPX terminal to a higher-order
controller for preparing commissioning.

You will thus avoid addressing faults which may occur in
various field bus systems when address ranges are
modified during operation.

3.2.1 Checking the CP strings

Preparations Before commissioning a CPX terminal with CPX-CP interface,

you should first prepare each individual CPI system for com­missioning.

Proceedasfollows:

1. Check the pneumatic tubing connections of the
connected CP valve terminals with the help of the manual
override ( pneumatics description).

2. Check the complete electric circuitry of the CP system.

3. Save the current string assignment of th e CPI system as
the set assignment, as described in section 3.2.2.

3.2.2 Saving the string assignment

Warning

Undesired modification of input and output addresses.
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 can thereby avoid:
– addressing faults with incorrectly fitted CPI modules.

String allocation The CPX-CP interface saves the type and sequence of the

connected CPI modules for every string ( chapter 1). This
is also termed string assignment.

The saved string assignment allows the CPX-CP interface to
avoid errors in connecting, and thus addressing errors. 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 ( section 3.3)

– Testing during operation ( section 3.4).

After the switch on procedure, the status LEDs indicate the
operating status and correct function of the bus node and the
fieldbus communication. If the status LEDs on all the CPI/CP
modules light up, the CPI system is prepared for configuration.
You can find out which indicator displays the normal operat­ing status in the user documentation of the respective CPI
module. Different procedures are necessary for configuration
of the various fieldbus nodes or the FEC.

Festo P.BE-CPX-CP-EN en 1211b

Explanations on this can be found in the manual for the CPX
field bus node or the CPX-FEC.

3. Commissioning

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 modules.

Save the string assignments as follows:

1. Leave the power supply of the CPX terminal switched off
for the time being.

2. Check that each of the CPI/CP modules is connected to
the string which provides the address range intended
( chapter 1).

3. Check that the CPI cables are fastened properly with the
union nut.

4. Switch on the power supply of the CPX terminal and, if
necessary, of the CPI/CP modules with load voltage con­nection.
On the CPX-CP interface, the LEDs of strings (L1 ... L4), to
which CP modules have been connected or for which the
string assignment has been modified, will flash.

5. Use a small screwdriver or similar to press the Save key
for at least 1 s ( section 2.1).
This will save the current string assignment as the target
string assignment in the CPX-CP interface.
The LEDs of strings (L1 ... L4), with which the connected
CPI/CP modules have been recognised, no longer flash.
ThestatusLEDsofalltherecognizedCPI/CPmodules
light up. Wait some seconds before continuing with the
next step.

6. Switch off the power supply for the CPX terminal. Wait
some seconds. Then switch it back on again.
The current string assignment is now available in the
fieldbus node or the CPX-FEC.

7. Depending on the CPX field bus node or CPX-FEC being
used, the modified address range of the CPX-CP interface
must be accepted:

How to accept the address range

System parameter “System start” [System start]:

“System start with default p arameterisation and up-to-date CPX
expansion” [default parameters], (factory setting):
– The revised address range of the CPX-CP interface is automatic-

ally accepted.

“System start with saved param eterisation and saved CPX expan­sion” [saved parameters]:

1. Change “System start ...” system parameter to “... default
parameterisation ...” .

2. Switch off the power supply of the CPX terminal then switch it
on again. The address range of the CPX-CP interface will then
be accepted.

3. If necessary, you can restore the desired parameterisation.

•

To accept the address range of the CPX-CP interface, you must
save the actual configuration as the set configuration (actual­setpoint comparison). Information on this can be found in the
manual for the CPX-FEC or software package FST 4.1.

3.3 Switching-on reaction of the CPI system

When the power supply is switched on, the CPX-CP interface
ascertains automatically the current string assignment. It
ascertains one after the other which CPI modules are con­nected to the relevant string.

If the current assignment is the same as the saved assign­ment, the CPX-CP interface will switch automatically to the
ready status.
The RN LED of the CPX-CP interface as well as the status LEDs
on the connected CPI/CP modules light up ( Fig. 3/1).

If the current assignment is not the same as the saved as­signment, the string LEDs (L1 ... L4) of the relevant string will
flash on the CPX-CP interface. 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 errors manually or replace

individual CPI modules ( section 3.4)

– Save the current assignment as the set assignment

( section 3.2.2).

Detailed notes on diagnosing the CPX-CP interface using the
LEDs can be found in section 4.2.

LED (L1 ... L4) flashing or lighting up. on the CPX-CP interface.
The status LED on the relevant module goes out. All modules
working without faults remain ready to operate.

Detailed notes on diagnosing the CPX-CP interface using the
LEDs can be found in section 4.2.

3.4.1 Eliminating assignment faults

In order to eliminate assignment or connection faults of the
CP system:

1. Switch off the power supply for the CPX terminal.

2. Restore the saved assignment by connecting the
appropriate CPI/CP modules with the CXP-CP interface
again.

3. Switch on the power supply for the CPX term inal again.

3.4.2 Replacing CPI/CP modules

Replacement possibilities Only one defective CPI/CP module can be replaced with a

CPI/CP module of the sa me type without the need to save
the string assignment again.

Note

Replacing a CPI/CP module with a CPI/CP module of a dif­ferent type or replacing several CPI/CP modules will re­quire a new commissioning and new saving of the string
assignment ( section 3.2).

In order to replace a single CP module, proceed as follows:

1. Stop the process controller P LC/Master

2. Switch off the power supply for the CPX terminal.

3. In the case of CPI/CP output modules and CP valve
terminals on the CP string concerned:
Switch off the following sources of energy:
– the compressed air supply for the CP valve terminal
– the o perating voltage supply for the CPI/CP output

module.

4. Disconnect all connecting cables and, if necessary, also
the tubing.

5. Connect all connecting cables and, if necessary, the
tubing with the identically constructed new module.

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

Festo P.BE-CPX-CP-EN en 1211b

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

8. Switch on the power supply for the CPX term inal again.

9. Check the addresses of the CPI system.

3. Commissioning

3.4.3 Replacing CPI/CP modules during operation

In special cases, a single CPI/CP module can be replace d
during operation with a CPI module of the same type.

In rare cases, the replacement can produce a short circuit
report for the string. Restart the system if there is a short
circuit report.

Warning

Undesired modification of I/O states.

• Check whether the design of your machine/system
permits replacement of modules during operation.

Warning

Undesired modification of input and output addresses.
Be very careful if the string assignment of your CPI system

is modified at a later stage:

• Make sure that modules are not sepa rated from a string
and subsequently connected to another string during
operation. Use the identification labels (type IBS 6x10 or
IBS9x20) in order to identify modules clearly.

You can thereby avoid:
– modified input and output addresses of the modules.

The CPX-CP interface will recognise replacement with a differ­ent type of module (e.g., O module replaced with a valve ter­minal or CP-E16-M8 replaced with CP-E16-M12x2) as a string
assignment fault. In this case, therefore, readiness to operate
is not restored to the relevant module during operation.

Recommendation:
When replacing CPI/CP modules, always switch off the power
supply if possible ( section 3.4.2).

3-12

Festo P.BE-CPX-CP-EN en 1211b

3. Commissioning

If the design of your machine/system makes it necessary to
replace a CPI/CP module during operation, you should
proceed as follows:

1. In the case of CPI/CP output modules and CP valve
terminals on the CP string concerned:
Switch off the following sources of energy where
applicable:
– the compressed air supply to the valve terminal
– the o perating voltage supply to the output module.

2. Disconnect all connecting cables and, if necessary, also
the tubing.

3. Connect all connecting cables and, if necessary, the
tubing with the identically constructed new module.

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

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

You can thus restore the defective connection during
operation, or replace the defective module without impairing
operation of the modules in the other strings. When the
connection is restored again or replaced, the readiness to
operate will be taken up with the appropriate module
automatically.

Restriction in recognising the string assignment

Specific modifications to the string assignment cannot be
recognised during operation:

– CPI/CP modules or entire strings which are connected to

the previously unassigned string 2 instead of string 1 or
vice versa. This also applies to strings 3 and 4, respect­ively.

However, these modules will retain their previous addresses
until the power supply is switched off and then on again.

Note

Modifications to the string assignment will be recognised
reliably after the power has been switched on.

Recommendation:

• If possible, switch the power supply off and t hen on
again after performing conversion work on the
CP strings, provided that your system permits this.

Note

After saving the string assignment, check the address
assignments of your CPI system before starting user
programs.

You can thereby avoid:

– addressing faults with incorrectly fitted CPI/CP modules.

3.5 Notes on operation

Warning

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

dangerous situations.

• M ake sure that valves and outputs are put into a safe
state when faults occur.

Note

Please note the following if the outputs of a valve terminal
are reset after master 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 (depend-

ing on valve type: pressurized, exhausted or blocked).

Warning

Undesired modification of input and output addresses.
Be very careful if the string assignment of your CPI system

is modified at a later stage:

• Make sure that modules are not separated from one
string and accidentally connected to another. Use the
identification labels (type IBS 6x10 or IBS9x20) in order
to identify modules clearly.

• After saving the string assignment, check the address
assignments of your CPI system before starting user
programs.

You can thereby avoid:
– modified input and output addresses of the modules.

All the CPI/CP modules of the recognised string assignment
are now each displayed with string number (e.g. L1), module
number on the string (e.g. M0) and their long name.

If no modules are recognised on the strings, the message
“No CP modules” will be displayed.

The following CPI/CP modules are marked with “x”:

– Modules recognised after the power supply has been

switched on but not included in the saved string assign­ment.

– Modules contained in the saved string assignment but

no longer recognised.
In this case the CPX-CP interface will report a configura­tion error.

Malfunctioning CPI/CP modules (modules reporting an er­ror, e.g. short circuit) are marked with “!”. Diagnostic in­formation about each of these modules can be displayed.

These special system errors occur in very rare cases. The CP
interface has detected an error that requires a software stop.
The error is displayed through flashing of all CPI-specific LEDs
(PS, PL, RN, P). In addition, an error message is shown en­coded through flashing of the LEDs L1 … L4 ( Tab. 4/4 and
Tab. 4/5).

•

In the event of error, restart the CPX terminal with POWER
OFF/ON and observe the instructions in the tables
