Festo P.BE−CPX−FB6−EN en 0402b
The following Interbus−specific terms and abbreviations are
used in this manual:
Term/abbreviation Meaning
CMD software Parametrizing, commissioning and diagnostic software for slaves on the
Interbus (configuration, monitoring, diagnosis).
ID 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 The module is the central device for checking the Interbus data ring. 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.
Parameter data Data for parametrizing, diagnosis and configuration which are transmitted
acyclically in multiplex procedure via the PCP channel.
PCP channel Slaves, which can also process parameter data, are also known as PCP
slaves. Communication between these slaves and the module takes place
via the Peripheral Communication Protocol (in brief: PCP or PCP channel).
PCP is an integral part of the Interbus protocol.
Peripheral fault (PF) Faults in the peripherals of Interbus slaves are shown by means of periph
eral 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 General instructions on installation
Warning
Before carrying out installation and/or maintenance work,
switch off the following:
·the compressed air supply
·the operating voltage supply for the electronics/sensors
·the load voltage supply for the outputs and valves.
You will thereby avoid:
 uncontrolled movements of loose tubing
 uncontrolled movements of the connected actuators
 undefined switching states of the electronics.
Caution
The CPX field bus node for Interbus contains electrostati
cally sensitive components.
·Do not touch the electrical contacts of the components.
·Observe the regulations for handling electrostatically
sensitive components.
In this way you will avoid damage to the electronics.

Dismantling and fitting
The field bus node is fitted in a manifold sub−base of the CPX
terminal (see Fig.1/2).
Dismantling Dismantle the field bus node as follows:
1. Loosen the four screws of the field bus node with a Torx
screwdriver size T10.
2. Pull the field bus node carefully and without tilting away
from the contact rails of the manifold sub−base.
