<p>PURPOSE:To provide a process controller which can specify the cause of trouble in target operation through a simple system without requiring any logic diagram or extensive development of AND/OR graphs. CONSTITUTION:The process controller comprises a memory 3 for correlating the operational targets with execution premise conditions, i.e. plant conditions, and storing as a control data, a ROM 2 for comparing the execution premise conditions with actual values for a predetermined operational target to velify a control data which is the further premise conditions for aforementioned execution premise conditions thus automatically storing the control program, an I/O unit 6 for instrumentation controller of plant, other process controllers, and an operator, and a processor 1 for executing the processing according to a program stored in the ROM 2 and delivering a control instruction or a display instruction to an I/O unit 6.</p> |
