Intended use
The CPX analogue I/O modules described in this manual have
been designed exclusively for use in conjunction with CPX
terminals from Festo. The analogue I/O modules must only be
used as follows:
–asintended
– in perfect technical condition
– without any modifications by the user.
If commercially available accessory components such as
sensors and actuators are connected, the specified limits for
pressures, temperatures, electrical data, torques etc. must be
observed.
Please observe the standards specified in the relevant
chapters and comply with the regulations of the trade
associations and the German Technical Control Board (TÜV),
the VDE conditions as well as the relevant national
regulations.
Warning
•Only use PELV power circuits according to IEC/DIN
EN 60204-1 (Protective Extra-Low Voltage, PELV) for the
power supply.
Also take into account the general requirements for PELV
power circuits according to IEC/DIN EN 60204-1.
•Only use power sources that guarantee reliable
electrical isolation of the operating voltage according to
IEC/DIN EN 60204-1.
Protection against electric shock (protection against direct
and indirect contact) is guaranteed in accordance with
IEC/DIN EN 60204-1 (electrical equipment of machines,
general requirements) by using PELV power circuits.

Notes on the use of this manual
This manual contains general basic information about the
mode of operation, fitting and installation of analogue
CPX I/O modules, CPX connection blocks and CPX pneumatic
interfaces.
General basic information about the mode of operation, fit-
ting, installation and commissioning of CPX terminals can be
found in the CPX system description.
Specific information about commissioning, parameterisation
and diagnostics of CPX terminal with the bus node you are
using can be found in the appropriate manual for the bus
node.
Information about further CPX modules can be found in the
manual for the respective module.
Information about MPA pneumatic and electronic mod-
ules can be found in a separate description of type
P.BE-MPA-ELEKTRONIK-...
An overview of the structure of the CPX terminal user
documentation is contained in the CPX system description.
CPX analogue I/O modules
The I/O modules each consist of the electronic module as well
as a connection block and an interlinking block. Note the pos-
sible combinations of connection blocks and electronics mod-
ules in section 1.2.2.
This manual contains information on the mode of operation,
the fitting and installation of the following modules:

Diagnosis via the field bus or a network
Depending on the parameterisation, CPX I/O modules report
the specific errors 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
– error numbers.
Further information on diagnosis can be found in the
CPX system manual or in the manual for the bus node.
