    2 principle of operation the electropneumatic positioner is attached to pneumatic control valves. It is used to assign the valve position (controlled variable x) to the control signal (reference variable w).

    As a standard feature, the positioner comes with a binary input used to signalize process infor- mation over the f oundation™ fieldbus network. The extended expertplus diagnostics are integrated into the positioner. They provide informa- tion on the positioner and generate diagnostic and status mess...
