matic modules each represent an electric module with e.g.
8digital outputs for controlling the valves fitted
(seechapter 2).
Please note
The pneumatic interface for MPA pneumatics provides the
mechanical and electrical connection to the MPA pneu
matic modules.
As regards the CPX terminal, this pneumatic interface does
not therefore count as an electric module.

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 and load voltage supplies.
The CPX terminal must first be dismantled before it can
be
extended or converted, or when a pneumatic interface must
be replaced. Instructions on this can be found in the CPX
system manual.
Instructions on extending or converting the pneumatic
modules can be found in the appropriate pneumatics manual.

1.3 Settings for configuring the pneumatics
Midi/Maxi, CPA or
VTSA pneumatics
Settings for configuring the pneumatics are only necessary
with the pneumatic interfaces for Midi/Maxi, CPA and VTSA
pneumatics (ISO).
No settings are required for MPA pneumatics.
Caution
After conversion or extension of the Midi/Maxi, CPA or
VTSA pneumatics, the number of output addresses occu
pied by the pneumatics must be set on a DIL switch on the
pneumatic interface.
CPX terminals can be fitted with various valves and electric
modules in accordance with the customer’s wishes.
The size of the
valve address range on Midi/Max, CPA or
VTSA pneumatics is not modified when the valves are ex
tended or converted, providing sufficient address space has
already been reserved for the extension. The valve address
range must be set with a DIL switch. The DIL switch is situ
ated under the transparent cover on
the pneumatic interface.

Caution
Modules may be damaged if they are not handled
correctly.
· Do not touch the electrical contacts of the modules.
· Observe the regulations for handling electrostatically
sensitive components.
· Discharge yourself electrostatically before fitting or re
moving components in order to protect the components
against discharges of static electricity.
Please note
Handle all modules and components of the CPX terminal
with great care. Please note especially the following:
· Screws must be fitted accurately (otherwise threads will
be damaged).
Screws must be fastened at first only by hand. Place the
screws so that the self−cutting threads are used.
· The specified torques must be observed.
· Screw connections must be fitted free of offset and
mechanical tension.
· Check the seals for damage (IP65).
· Connecting surfaces must be clean (to ensure sealing
effect, avoid leakage and contact faults).
The screw connection between the cover and the lower
part of the CPA pneumatic interface is designed for at least
10 fitting/removal cycles.

Rules for setting
If the number of valve solenoid coils fitted is less than the
number of output addresses set with the DIL switch, the
superfluous addresses will be reserved for later exten
sions (if the maximum number of valves is fitted, output
addresses will then remain unused).
Modifications to the configuration will not become
effective until
8 further output addresses per switch element will be
assigned for valves in the address range.
The setting of the highest−value DIL switch in the ON
(closed) position is decisive for the assigned address
range.

Specific faults of the pneumatic interfaces are registered or
suppressed depending on the module parametrizing.
The faults are shown on−the−spot by means of the Fault LED
and, if necessary, can be evaluated with the Handheld (MMI).
Depending on the module parametrizing, the faults are sent
to the field bus
node, where they can be evaluated according
to the field bus protocol used.
With the MPA pneumatics, parametrizing takes place via the
individual MPA pneumatic modules (module−orientated, see

2. MPA pneumatic modules
2.1 Function of the MPA pneumatic modules
In the CPX terminal the MPA pneumatic modules provide
digital outputs for controlling the valves and thus enable
pneumatic actuators to be controlled.
From a technical point of view, the individual pneumatic
modules each represent a separate electric module with
digital outputs.
Without intermediate electrical supply (see section 2.3)
maximum 8 MPA pneumatic modules
terminal. Up to 64 valve solenoid coils (exclusively MPA1) or
32valve solenoid coils (exclusively MPA2) are therefore
possible.
With intermediate electrical supply (see section 2.3) maxi
mum 16 MPA pneumatic modules are permitted per CPX
terminal. Up to 128 valve solenoid coils (exclusively MPA1)
or 64valve solenoid coils (exclusively MPA2)

2.2 Fitting
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 and load voltage supplies.
The CPX terminal must first be dismantled before it can
be
extended or converted, or when a pneumatic interface must
be replaced. Instructions on this can be found in the CPX sys
tem manual.
Instructions on extending or converting the MPA pneumatic
modules can be found in the appropriate pneumatics manual.
Electronic modules or valve plates can be replaced on the
fitted CPX terminal.
Caution
Modules may be damaged if they are not handled
correctly.
· Do not touch the electrical contacts of the modules.
· Observe the regulations for handling electrostatically
sensitive components.
· Discharge yourself electrostatically before fitting or re
moving components in order to protect the components
against discharges of static electricity.

2. MPA pneumatic modules
Please note
Handle all modules and components of the CPX terminal
with great care. Please note especially the following:
· Screws must be fitted accurately (otherwise threads will
be damaged).
Screws must be fastened at first only by hand. Place the
screws so that the self−cutting threads are used.
· The specified torques must be observed.
· Screw connections must be fitted free of offset and
mechanical tension.
· Check the seals for damage (IP65).
· Connecting surfaces must be clean (to ensure sealing
effect, avoid leakage and contact faults).
Dismantling the electronic module
1. Use a screwdriver with a narrow blade to loosen the
fastening screws of all valve or blanking plates and
remove the plates from the sub−bases.
2−8
2. Loosen the screws with which the electronic module is
fastened to the sub−base.
3. Pull the electronic module upwards out of the body of the
sub−base.

Caution
Replace an electronic module only by an electronic module
of the same type (see section 2.3).
Please note
Before fitting, check the condition and position of the
following seals:
the sealing lip of the electronic module
the ring seal of the electrical contacts
the flat seal of the valve plates or blanking plates.
1. Place the electronic module in the sub−base.
2. Tighten the screws of the electronic module with
0.2...0.25Nm.
2−10
3. Then fit
the valve plates or blanking plates. Check the
seals of the valve or blanking plates for damage. Replace
seals if they are damaged.
4. Make sure that the seals are seated correctly.
The flat seal between the sub−base and the component
must be seated in the recess in the component. The ring
seals between
the electronic module and the component
are conical. The ring seals must be fitted on the guide
pins of the components so that the cone slides easily into
the appropriate recess in the electronic module
(seeFig.2/3).
5. Place the components on the sub−base.
6. Screw the components at first only slightly and then
tighten with 0.2
... 0.25 Nm.

3. Overview and connecting technology I/O modules
3.1 Components of an I/O module
All I/O modules consist of three parts:
The sub−base provides the electrical connections in the
form of different sockets or terminal strips.
The electronic module contains the printed circuit board
with the electronics and the LED display of the I/O mod
ule. The electronic module is fitted into the sub−base and
is connected to
means of electric plug connectors.
The manifold sub−base as the lower part of the housing
provides the mechanical and electrical link between the
module and the valve terminal.

3. Overview and connecting technology I/O modules
3.2.3 Connecting the cables and plugs to the sub−bases
Sensors and actuators must be connected to the CPX I/O
modules only at the sub−bases. In this way, e.g. when an elec
tronic module is replaced, the plugs and cables remain fitted
in the sub−base.
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 and load voltage supplies.
Festo P.BE−CPX−EA−EN en 0705f
The protection class of the I/O modules depends on the
sub−
base used as well as on the plugs and protective caps used.
Instructions can be found on the following pages and in the
Appendix A.6.
Use plugs and cables from the Festo range for connecting
sensors and actuators (see Appendix A.10).

2. Align the sub−base over the manifold sub−base with the
electronic module. Make sure that the plug connectors of
the sub−base are aligned exactly with the connectors of
the electronic module. Then push the sub−base carefully
and without tilting onto the manifold sub−base.
3. Tighten the screws at first only by hand. Place the screws
that the self−cutting threads can be used.

3.3.2 Fitting the screening/shield plates
A screening plate type CPX−AB−S−4−12 can be fitted on sub−
bases CPX−AB−4−M12x5−5POL and CPX−AB−4−M12−8POL.
The sub−base must be removed before the terminal is fitted
or dismantled.
Fitting Fit the screening plate as follows (see Fig.3/9):
1. Dismantle the sub−base (see section 3.3.1).
2. Snap the spring clips of the screening/shield plate from
above into the appropriate recesses
sub−base.
3. Fit the sub−base.
Instructions on earthing the screening/shield plate can be
found in section 3.2.3.
Dismantling The screening/shield plate must be removed in the opposite
sequence to the fitting procedure.
