PROBLEM TO BE SOLVED: To provide a control unit that makes clear processing and handshake processing omissible from a program for controlling a PLC and efficient programming and realize sure control of a controlled object. SOLUTION: An analysis executing part 102 reloads signals in an interface signal storage part 103 according to a working program 101 or the like. A PLC 106 performs the control of the controlled system according to a PLC program 105 and reloaded signals. A pulse width control part 104 returns the reloaded signals original after the lapse of a prescribed time. According to the signals returned to original state, the PLC 106 starts the other control of the controlled system. Because of the operation of the pulse width control part 104, it is not necessary to describe the clear processing of the signals in the working program 101. Further, because of the other control performed by the PLC 106, it is not necessary to describe the handshake processing in the working program 101 and PLC program 105.
