Designated use
CPX terminals are designed for fitting into a machine or an
automated system. Depending on the CPX node used, they
can be connected to a special field bus system and serve for
interrogating sensor signals and for controlling pneumatic
and electric actuators.
The individual CPX modules of the CPX terminal are docum-
ented in specific manuals. The safety instructions listed in the
manuals must always be observed and the relevant CPX mod-
ule must only be used as intended. CPX modules and cables
are only to be used as follows:
– in accordance with designated use
– in their original state
– without any modifications by the user
– in faultless technical condition.
When used together with commercially available compo-
nents, such as sensors and actuators, the specified limits for
pressures, temperatures, electrical data, torques etc. must be
observed. National and local safety regulations must also be
observed.

1.1 Structure of the CPX terminal
CPX terminals consist of electric and pneumatic modules for
controlling pneumatic actuators and low-current consuming
electric devices (further valves, bulbs, etc.). They are usually
placed decentrally directly on the machine or system.

CPX terminals with field bus connection permit communica-
tion with remotely-situated higher-order control systems. CPX
terminals are constructed on a modular basis and can consist
e.g. of the following modules:
