Intended use
The CPX pneumatic interfaces, MPA pneumatic modules and
CPX I/O modules described in this manual have been de
signed exclusively for use in conjunction with CPX terminals
from Festo. The pneumatic interfaces and I/O modules are
only to be used as follows:
asspecified in industrial applications
 without any modifications by the user
Only the conversions or modifications described in the
documentation supplied with product are permitted.
Inperfect technical condition.
If additional commercially−available components such as
sensors and actuators are connected, the specified limits for
pressures, temperatures, electrical data, torques, etc. must
not be exceeded.
Please observe the standards specified in the relevant
chapters and comply with technical regulations, as well as
with national and local regulations.
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).
Take 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 guar
anteed in accordance with IEC/DIN EN 60204−1 (electrical
equipment of machines, general requirements).

Notes on the use of this manual
This manual contains general basic information on the
method of operation, on fitting and installing CPX pneumatic
interfaces, MPA pneumatic modules and CPX I/O modules.
General basic information on the method of operation, on
fitting, installing and commissioning CPX terminals can be
found in the CPX system manual.
Special information on commissioning, parametrizing and
diagnosing a CPX terminal with the field bus node you are
using can be found in the appropriate manual for the field
bus node.
Information on further CPX modules can be found in the
manual for the relevant module. An overview is provided in
table Tab.0/4.
Conventions
The special parameters of the modules are described in the
individual chapters. These appear in English on the Handheld
type CPX−MMI−1.

Diagnosis via the field bus
Depending on the parametrization, CPX pneumatic interfaces
and CPX I/O modules register specific faults via the field bus.
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 field bus node.

The following product−specific terms and abbreviations are
used in this manual:
Term/abbreviation Meaning
A Digital output
CPX modules Common term for the various modules which can be incorporated in a
CPX terminal.
CPX terminal Modular, electric terminal type 50
Diagnosis D2 Additional diagnostic functions of MPA input modules (see section 2.5)
DIL switches Dual−in−line switches consist of several switch elements with which set
tings can be made.
E Digital input
Field bus node Provides the connection to specific field buses. Transmits control signals
to the connected modules and monitors their ability to function.
I/O diagnostic interface The I/O diagnostic interface is a bus−independent diagnostic interface at
I/O level, permitting access to internal data of the CPX terminal.
I/O modules Common term for the CPX modules which provide digital inputs and out
puts (CPX input modules and CPX output modules).
I/Os Digital inputs and outputs
Input module CPX input module
Manifold sub−base Upper part of the housing of a module or block for linking the module
electrically with the terminal.
MPA electronic module Electronic module which provides the electronic functionality including
the diagnostic functions for the valve solenoid coils of the MPA pneu
matics.
MPA pneumatic module Pneumatic module which provides digital outputs for the valves fitted
(valve solenoid coils).
Output module CPX output module
PLC/IPC Programmable logic controller/industrial PC
Pneumatic interface The pneumatic interface is the interface between the modular electrical
periphery and the pneumatics.
