Term/abbreviation Significance
Pneumatic interfac e The pneumatic interface (port pattern) is the interface between the CPX
modules and the pneumatics modules ( Valve terminal); the
pneumatic interfac e serves to connect the valve terminal pneumatics to
the CPX terminal; it creates the mechanical connection between the
electric and pneumatic side and ensures transmission of the electric
signals; the pneumatic interface counts functionally as on the “electric”
side of the CPX terminal
Pneumatic modules Collective term for the pneumatic modules which can be integrated into
aCPXterminal( Valve terminal); pneumatic modules form the
“pneumatic” side of the CPX terminal

STI I/O diagnostic interface (System Table Interface)
Valve terminal Electromagnetic valves with shared power supply, air supply and
control; the valves and pneumatic components on the right side of the
pneumatic interface together form the valve terminal pneumatics
