1.1.1 Method of operation of the CP system
CP systems are composed of the following modules:
CP modules Function
CP master Special CP field bus nodes and CP modules
are available for the various field buses.
These provide the connection to certain
field buses.
These offer connections for up to four
strings to which I/O modules and CP
valve terminals are connected.
These transmit control signals to the
connected modules and monitor their
functioning.
CP valve terminals These provide different valve functions
via valve plates for controlling pneu
matic actuators.
Relay plates, pressure zone separation
plates and blanking plates can also be
fitted.
Input modules
These provide inputs for connecting
sensors and enable e.g. cylinder
positions to be scanned.
Output modules These provide universal electric outputs
for controlling low−current consuming
devices (further valves, bulbs etc.).
