Zusammenfassung:	PROBLEM TO BE SOLVED: To quickly and accurately control a control object in control under which high speed performance is required by controlling the start, stop and revolving speed of a motor without generating any delay correspondingly to a detection result from a pulse generator without being affected by the refresh time and refresh timing of a programmable controller.SOLUTION: The programmable controller is configured to, regardless of the refresh timing of a CPU device 12, perform specific processing of, for example, directly processing a pulse signal to be output from a specific pulse generator or the like to generate interlock and drive transmission data by an intelligent function part 113 arranged in a pulse counter unit 114 of an input/output device 11, and transmits the interlock and drive transmission data or the like via a transmission loop 40 to a drive device 20 to control a motor arranged in a steel plant or the like to execute the rolling process of steel via the drive device 20.
