Abstract

PURPOSE:To apply a process controller easily to an intermittent controller and an override controller, by providing a PID (proportion, integration, and differentiation) operating package having specific input and output terminals to perform specific operations. CONSTITUTION:If the control mode is changed between the preceding sampling and the current sampling for signals given to prescribed first fourth input terminals H1, H2, P1, and P2, an deviation EN between a remote target value RSP or an internal local target value LSP and a process variable signal PV is subjected to only the speed integration operation, and a position control signal CN1 is added to this operated value to output a position control signal to an output terminal OUT. When a flag signal turn-on is given to the input terminal P2 if the control mode is not changed, the deviation EN is subjected speed proportion and integration operations, and the position control signal CN1 is added to this operated value to output a current position control signal.
