PURPOSE:To control the power supply to an automatic operation controller which turns on and off the power supply in accordance with a program through a switch, by providing an operating section equipped with a manually operating switch and operating this operating section with firmware. CONSTITUTION:A CPU29 sets the power supply-on/off program of an object device in the control section 21 of an automatic operation controller through an interface 28. The control section 21 displays set on/off time on a panel board 23 in accordance with a set program and, at the same time, turns on/off the output contact section of a relay section 27 through an output buffer 26 in accordance with the program. The firmware of the control section 21 reads the switching state of an operating section 25 at evey fixed time and, when an operator depresses a turning-on switch, it is recognized by the firmware and the output contact of the relay section 27 is turned on. Similarly, when the operator depresses a breaking switch, the output contact of the relay section 27 is turned off. |
