Abstract

PURPOSE: To ensure an exchange of the power source using part without disturbing the operation of the system, by providing the power source on/off part which detects the power source on/off signal and then switches on and off the power source to each of several processors connected to the common bus.
CONSTITUTION: The processor connected to the common bus 20 consists of the control part 1 and the peripheral unit 2. And the part 1 comprises the interface circuit 31, the disconnecting switch control circuit 32 functioning as the power source on/off detection part, the disconnecting switch 12 functioning as the power soruce on/off part, and the control part 13 each. The part 13 and the unit 2 function as the power source using part each. The control instruction for the make or the break of the power supply lines 41 and 42 is transmitted to the circuit 32 via bus 20, information line 21, the circuit 31 and the information line 22 each, and then transmitted to the switch 12 from the circuit 32 via the signal line 51. Thus the break and make of the power source is given to the line 42 via the switch 12. At the same time, the on/off action of the power supply is conveyed to the circuit 32 from the switch 12 in the form of the state signal, and also can be transmitted to the bus 20 by the control instruction. Thus the power source part can be exchanged without giving any effect to the bus 20.
