PURPOSE:To rationalize the control of a power supply, by comparing the address proper to an own device with the device address given from a service processor and actuating other circuit parts when the own device is selected. CONSTITUTION:Both the data signal and the control signal are transmitted and received via an input/output bus 2 that connects a service processor SVP1 and each power supply controller 3. At a device address receiving part 5 that detects the selection of the own device, the device address command given from the processor SVP1 is compared with the own proper address to detect the coincidence between them. Then other receiving parts, control parts, etc. are actuated by a signal line 13. The data which is transmitted after the device address command is received 7 to decode 8 the control command. Thus the device or the peripheral device which is a subject for control of the power supply is recognized to decide the make or the break of the corresponding device or peripheral device. As a result, the make and the break can be rationally carried out in a collective or selective way for the power supply of each controller. |
