The CPX terminal must only be used as follows:
– As specified in industrial applications.
– In an original condition, without any modifications by the
user. Only the conversions or modifications described in
the documentation supplied with the product are permitted.
– In perfect technical condition.
The limit values specified for pressures, temperatures, elec-
trical data, torques etc. should be observed.
If conventional accessory components such as sensors and
actuators are connected, the specified limits for pressures,
temperatures, electrical data, torques etc. should be ob-
served.
Comply with the legal rules and regulations and standards,
rules of the testing organisations and insurance companies
and national specifications applicable for the location.
Target group
This manual is intended exclusively for technicians trained in
control and automation technology who have experience in
installing, commissioning, programming and diagnosing pro-
grammable logic controllers (PLC) and the Interbus fieldbus

The following product-specific terms and abbreviations are
used in this manual:
Term/abbreviation Meaning
CPX bus Data bus via which the CPX modules communicate with each other and
are supplied with the necessary operating voltage.
CPX modules Collective term for the various modules which can be integrated in a CPX
terminal.
CPX terminal Modular electric terminal type 50
DIL switch Dual-in-line switches consist of several logic elements with which settings
can be made.
Bus nodes Create the connection to certain networks or fieldbuses, conduct control
signals to the connected modules and monitor their functioning.
Handheld (MMI) Handheld terminal (handheld, CPX-MMI) for CPX modules for
commissioning and service purposes (Man-Machine Interface, MMI).

The following Interbus-specific terms and abbreviations are
used in this manual:
Term/abbreviation Meaning
CMD software Parameterisation, commissioning and diagnostic software for slaves on
the Interbus (configuration, monitoring, diagnosis).
FOC Fibre-optic cables
Ident. code By means of the Ident code (in brief: ID code), the module ascertains the
type and the process data length of all the slaves.
Module ThemoduleisthecentraldeviceforcheckingtheInterbusdataring.
It exchanges the data transported serially in the data ring with the
higher-order controller or computer system and the lower-order Interbus
slaves in both directions acyclically or cyclically.
Peripheral fault (PF) Faults in the peripherals of Interbus slaves are shown by means of
peripheral faults (dependent on slave), e.g.
– load voltage failure
– short circuit at the outputs, etc.
The peripheral fault is a common fault message which does not contain
any module-specific information.
Process data I/O data from the Interbus slaves transmitted cyclically via the Interbus,
e.g. for:
– light barriers, sensors
– valves, fuses
– diagnostic I/Os
Remote bus The remote bus bridges long distances within an Interbus system
(main string). With baud rates of 500 kBd and 2 MBd it can be up to
12.8 km long (from the module to the last connected remote bus slave).
Individual segments can be up to 400 m long.

1.1 Fibre optic cable (FOC) connection
We recommend fibre optic cable technology for transmission
in environments subjected to heavy interference, as well as
for extending the range when high transmission speeds are
used.
This has the added advantage of high electromagnetic resist-
ance to interference due to the optical transmission of the
signals.

1.2 General instructions on installation
Warning
Before carrying out installation and maintenance work,
switch off the following:
• Compressed air supply
• the operating voltage supply for the electronics/sensors
• the load voltage supply for the outputs and valves
In this way, you can avoid:
– uncontrolled movements of loose tubing
– uncontrolled movements of the connected actuators
– non-defined switching states of the electronic components.
Caution
The CPX bus node for Interbus includes electrostatically
sensitive devices.
• Do not therefore touch any components
• Observe the handling specifications for electrostatically
sensitive devices.
They will help you avoid damage to the electronics.
