Abstract

PURPOSE: To reduce the load on an operation control unit, by setting specific points in plant condition times constituted by a plurality of plant detection points and by permitting of the execution of a program only when the specific point is in a prescribed state.
CONSTITUTION: An input data processing unit 14 performs necessary processing of plant input signals a1Wam and thereafter stores them on a data table 15 and compares the signals with those read at the preceding time. If there is a state change, the processing unit generates a state checking signal f. A condition table 17 generates a confirmation signal g only when the state checking signal coincides with the execution request index of the program to be executed. The input data processing unit 14 receives the confirmation signal g to supply a state change signal b to a program execution selecting unit 22 to select the corresponding program. As a result, the unnecessary load on the operation control unit is reduced and the processing capacity is heightened.
