Abstract

PURPOSE:To reduce the processing burden on a central control unit CCU by synchronizing control states of both systems with each other without data transfer between the CCU and a CCU to switch systems without momentary break at the time of system switching and restoration. CONSTITUTION:Common control information from a CCU 1 is given to devices 2A and 2B to be controlled of the current system and the stand-by system, and control means CCUs 22A and 22B of both systems control and monitor their own devices by this control information. Control and monitor states of devices 2A and 2B to be controlled are not reported to the CCU at all, and CPUs 22A and 22B of both systems compare data with each other to check coincidence. Thus, the monitor work of the CCU 1 is simplified and the processing burden on the CCU 1 is reduced.
