Abstract

PURPOSE:To simplify the hardwave logic of a common bus interface equipment, by connecting plural processors by a data system common bus and a control system common bus. CONSTITUTION:A data system common bus A is used for the data communication between processors, and a control system common bus is used for periodically supervising the status of each processor by the processor 1A. In case when it has become impossible to communicate a data due to a fault in the bus A, each processor is made to prepare for switching the system by use of the bus C. Each processor is made to prepare for switching the system by means of interruption as hardware by the control information of the bus. After the processor 1A has been switched to 1B by itself, the processor 1B sends out the control information to the processors 2B-nB from the control system common bus D connected to said processor 1B, and starts them by means of interruption as hardware. As a result, the system is continuously operated by a new system (processors 1B-nB).
