Abstract

PURPOSE:To detect abnormal sequence control, by timing the time that an apparatus to be controlled performs its operation in a fixed step, and by drawing alarm output when timed output exceeds fixed value. CONSTITUTION:A CPU2 reads step numbers, draws output data corresponding to each step and drives load 131-152 through an output circuit 8. When limit switches 16-19 function by the operation of load, the CPU2 reads the working conditions of the limit switches 16-19 through an input circuit 7, decides as to whether or not the switches satisfy conditions and brings a step register 63 to an incremental condition when the switches satisfy conditions. The maximum action time of an apparatus to be controlled in each step is memorized to the maximum set time register 51, and the CPU2 operates an alarm circuit 9 when step incremental time exceeds said maximum time.
