Abstract

PURPOSE: To perform the power supply control and constitution control for the entire system with high reliability, by controlling the on-line and off-line of communication line between the system controller and the unit to be controlled.
CONSTITUTION: The CPUO fetches only the interface signal in which the on-line signal fed from the control units SVP 0,1 is turned on and does not fetch the signal of interface in on state. Whether the interfaces 2-0 and 2-1 are logically connected to the control unit SVP or not, is controlled with the control units SVP 0,1 and CPU 0 does not know that.
