<p>PROBLEM TO BE SOLVED: To provide a robust process controller which can be applied to the abnormality or the like of controlled system equipment at one part as well by controlling a system without exactly expressing the control method of the system as a sequence in advance. SOLUTION: The fragment and attribute information of an AND/OR graph corresponding to the controlled system equipment read out of a read only memory means 2 is stored in units of object in a 1st temporary storage means 3 as the object. A supervisory and control task generating means 1a generates a supervisory and control task for achieving a control target by linking the fragments of the AND/OR graph recorded in the object based on the control target in units of object. A supervisory and control task executing means 1b periodically executes the generated supervisory and control task and outputs a command signal from the object to the relevant controlled system equipment.</p> |
