Diagnosis via the Fieldbus or a network
Depending on the parameterisation, CPX pneumatic inter
faces and CPX I/O modules signal specific faults via the Field
bus or your network.
These can be evaluated via the:
 Status bits (system status)
 I/O diagnostic interface (system diagnosis)
 Module diagnosis
 Fault numbers
Further information on diagnosis can be found in the CPX
system manual or in the manual for the bus node.

1.1 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 1.3)
maximum 8 MPA pneumatic modules are permitted per
CPX terminal. Up to 64 valve solenoid coils (exclusively
MPA1) or 32 valve solenoid coils (exclusively MPA2) are
therefore possible.
With intermediate electrical supply (see section 1.3) maxi
mum 16 MPA pneumatic modules are permitted per CPX
terminal. Up to 128 valve solenoid coils (exclusively MPA1)
or 64 valve solenoid coils (exclusively MPA2) are therefore
possible.
