Abstract

PURPOSE: To avoid the system down with the interruption of power supply of the input and output unit, without providing specific power supply with the input and output unit, by supplying power to the input and output unit from the power supply for CPU.
CONSTITUTION: In time sharing control of the input and output control unit IOC with a plurality of CPU CCo...CCn, FFo...FFn indicating whether the control unit IOC is under control or not to CPUCCo... CCn is provided, and the relays DLo...DLn controlled with FFo...FFn are provided. Further, power is fed to the control unit IOC from the power supplies PWo...PWn provided with CPUCCo... CCn via the contacts dlo...dln of the relays DLo...DLn. Thus, with the power supply to the control unit IOC from the power supplies PWo...PWn of CPUCCo... CCn, the systemdown due to power interruption of the control unit IOC can be avoided.
