Interface between CPX modules and pneumatics modules within a CPX
terminal.
The pneumatics interface is used functionally for the electrical side of
the CPX terminal.
Collective term for the pneumatics modules which can be integrated
into a CPX terminal.
Pneumatics modules provide, among other things, outputs (working
ports) for connecting actuators, e.g. cylinders.
Pneumatics modules form the pneumatic side of the CPX- terminal.
