Designated use
The CPX pneumatic interfaces, MPA pneumatic modules and
CPX I/O modules described in this documentation are in
tended exclusively for use in conjunction with Festo CPX ter
minals. The pneumatic interfaces and modules may only be
used as follows:
asintended in industrial installations
 without any modifications by the user
Only the conversions or modifications described in the
documentation supplied with the product are permitted.
infaultless technical condition.
If used together with additional commercially available com
ponents, such as sensors and actuators, the specified limits
for pressures, temperatures, electrical data, torques etc.
must be observed.
Observe also the standards specified in the relevant chapters,
as well as national and local laws and technical regulations.
Caution
Use only power units which guarantee reliable isolation of
the operating voltages as per IEC 742/EN 60742/VDE 0551
with at least 4 kV isolation resistance (Protected Extra Low
Voltage PELV). Switch power packs are permitted, provid
ing they guarantee reliable isolation in accordance with
EN60950/VDE 0805.
Note:
By the use of PELV power units, protection against electric
shock (protection against direct and indirect contact) is guar
anteed with the SPC10 in accordance with EN 60204−1/
IEC204. Safety transformers with the adjacent symbol must
be used for supplying PELV networks. The valve terminals
must be earthed to ensure that they function correctly (e.g.
EMC).

Diagnosis via the field bus
Depending on the parametrizing, CPX pneumatic interfaces
and CPX I/O modules register the specific faults via the field
bus.
These faults 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 and in the manual for the field bus node.

The following product−specific terms and abbreviations are
used in this manual:
Term/abbreviation Meaning
CPX modules Common term for the various modules which can be incorporated in a
CPXterminal
CPX terminal Modular, electric terminal type 50
DIL switches Dual−in−line switches usually consist of several switch elements with
which settings can be made.
Field bus node Provides the connection to certain field buses. Transmits control signals
to the connected modules and monitors their functioning.
I Digital input
I module CPX input module
I/O diagnostic interface The I/O diagnostic interface is a bus−independent diagnostic interface at
I/O level which enables access to internal data of the CPX terminal.
I/O modules Common term for the CPX modules which provide digital inputs and
outputs (CPX input modules and CPX output modules).
I/Os Digital inputs and outputs
Manifold sub−base Lower part of housing of a module or sub−base for electrical linking of the
module with the terminal.
MPA pneumatic module Pneumatic module which provides digital outputs for the fitted valves
(valve solenoid coils).
O Digital output
O module CPX output module
PLC/IPC Programmable logic controller/industrial PC
Pneumatic interface The pneumatic interface is the interface between the modular electrical
peripherals and the pneumatics.
Status bits Internal inputs which supply coded common diagnostic messages.
Sub−base Exchangeable upper part of housing of modules with connection
techniques.
