Abstract

PURPOSE:A unit incorporating a simulation processor and a control mode switch and providing automatic process simulation easily and rapidly by operation of the switch. CONSTITUTION:A process control unit 2 receives detection signals from a given process 1 by way of a process input device 3 and outputs operating signals through a process output device 5 subsequent to predetermined operation by an arithmetic controller 4. Parameters operated by the arithmetic controller 4 are selected as appropriate depending on processes handled, wherein simulation is ocasionally required to assure proper choice. This invention is embodied by the provision of the process control unit 2 which incorporates a simulation prosessor 7 and simulated process input and output devices 6, 8 and facilitates automatic simulation with the aid of a switch 9.
