Abstract

PURPOSE: To realize the simple and clear management system, by selecting the system constitution of master and slave control units at a bundle, while allowing self-contained system constitution selection of the unit, in a filure of specific slave control unit.
CONSTITUTION: Normally, selection of system constitution is made with the instruction of master control unit HS, but if there is a failure in specific slave control unit RM2, existing set R20 and spare unit R21 are first selected in RM2. After the system selection, the spare unit R21 informs the production of selection to the master control unit HS. In the master control unit HS, system constitution selection instruction is delivered to HS itself and slave control unit 1 system RM1WRMn to select the existing and spare system of the system. But, in the slave control unit RM2, no selection is made even after the reception of this instruction, because the selection is already made.
