Designated use
The CP system, consisting of a CP node, CP valve ter-
minals and CP input/output modules, referred to in the
following as CP modules, is designed to be fitted into a
machine or automation system. Depending on the CP
node used, the system can be connected to a special
fieldbus system and can be used for scanning sensor
signals and for controlling pneumatic and electric actua-
tors.
The individual CP modules of the CP system are do-
cumented in specific manuals. It is absolutely essential
that you observe the safety instructions listed therein,
as well as the designated use of the relevant CP mo-
dule. The CP modules and cables may only be used:
– as designated
– in their original condition
– without unauthorized modifications
– in faultless technical condition.
If used in conjunction with commercially-available com-
ponents such as sensors and actuators, the specified
limit values for pressures, temperatures, electrical data,
moments etc. must be observed. Please comply also
with national and local safety laws and regulations.

Target group
This manual is directed exclusively at technicians who
are trained in control and automation technology.
Important user instructions
This manual contains instructions on the possible
dangers which may occur if the CP modules are not
used correctly. These instructions are always printed in
italics, are framed and signalled by pictograms.
Danger
categories
A distinction is made between the following:
WARNING
This means that personal injury or damage to
property may occur if these instructions are not
observed.
CAUTION
This means that damage to property may occur if
these instructions are not observed.
PLEASE NOTE
This means that this instruction must also be
observed.

Pictograms and symbols complement the danger warn-
ings and draw attention to the nature and conse-
quences of dangers.
Pictograms
The following pictograms are used:
Uncontrolled movements of loose tubing.
Unintentional movements of the connected actuators.

1.1 Structure of CP systems
Festo can assist you in solving your automation tasks
at the machine level by means of valve terminals. Due
to their modular structure, valve terminals and I/O
modules from Festo can be incorporated to the best
advantage in your machines and systems.

1. System overview
CP... 9806A 1-3

The CP system consists of individual modules which
are connected by means of the CP cable. This permits
a decentralized arrangement of the CP system. The
compact CP valve terminals can be mounted very close
to the cylinders which are to be actuated, thereby enab-
ling short compressed air tubing to be used.
Short compressed air tubing minimizes the loss of air
flow and the times required for pressurizing and ex-
hausting the tubing.
This permits the use of smaller valves with sufficient
flow and thereby helps to reduce costs.

1.1.1 CP system module functions
CP systems consists of the following modules:
CP module Function
CP node There are special CP fieldbus nodes for the
various fieldbuses.
– They provide the connection to certain
fieldbuses
– They offer connections for up to 4 strings
to which I/O modules and valve terminals
can be connected
– They transmit control signals to the
connected modules and monitor their
functioning
CP valve
terminals – These provide various valve functions via valve plates for controlling
pneumatic actuators
– Relay plates, pressure isolating plates and
blanking plates can be used here as well
Input modules There are various special designs for
various types of connections.
– These provide inputs for connecting
sensors and permit e.g. the
scanning of cylinder positions
Output modules – These provide universally usuable electrical
outputs for actuating low current
consuming devices (further valves,
bulbs etc.)

CP... 9806A 1-5

Depending on type, the CP nodes control the transfer
of data to a wide variety of control systems via the
various fieldbuses. Some nodes have an integrated
PLC. This enables the CP system to be operated au-
tonomously without being coupled to a fieldbus.

When operated with a fieldbus, the control signals arriv-
ing from the fieldbus will be sent continuously by the
node to the connected CP modules. The CP modules
ensure that programmed output signals are transmitted
and that the appropriate valves are switched.
