Abstract
PURPOSE:To prevent an error output of a computer from bringing about a bad influence upon processes. CONSTITUTION:To stop automatically a plant using computer 11, several plant constituent apparatuses are stopped according to the schedule programmed in computer 11 and some others are started. Operation in a wrong stop order may cause an accident and control according to the schedule should be done. In other words, a computer output is required which corresponds to the process state varying with the progress of computer control. For example, when computer 11 is in a normal state, computer output (a) for stopping A apparatus 13 is sent out only in fixed process state A. Hovever, when output (a) is sent out not in state A, AND logic circuit 15 decides that the computer is in an abnormal state. Since there are some cases where the computer itself can not recognize this kind of error output, the abnormal state of the computer detected by this supervisory method is stored in and displayed by AND circuit 16 in sequential controller 14 or an alarm is outputted.
