Abstract

PURPOSE:To reduce the power consumption, by providing an electric power supply control part for turning on and off the electric power supply to an input/output control device, and constituting it so that the electric power supply is turned on only when an input/output device is used. CONSTITUTION:When a request is given to an I/O 104 from a control program 101, the program 101 outputs an electric power supply on command 105 to an input/ output control device 103. The device 103 instructs the electric power supply on of the I/O 104, to an electric power supply control part 108. The control part 108 sends out an electric power supply on signal 109 to an electric power supply controlling interface 111. When the signal 109 is detected, the I/O 104 turns on the electric power supply. Subsequently, when the program 101 detects a processing end, the program 101 outputs an electric power supply off-command 105 of the I/O 104. In accordance with said command, the control part 108 sends out an electric power supply cutoff signal 110 to the interface 111. When the signal 110 is detected, the device 104 turns off the electric power supply.
