Abstract
PURPOSE: To suppress the disrtubance at changeover to th backup unit, through the constitution of the control unit every control objective so that another control objective can be controlled and the backup to avoid mutual backup system in case of failure of other control units.
CONSTITUTION: Th control variables B1WB4 are individually controlled with the control circuits P1WP4 of th control units CU1WCU4 provided as the main system respectively based on the input signal from the input circuits IN1WIN4. Further, the control unit CU1 is taken as the backup system of CU2, CU2 is as CU3, CU3 is as CU4, and CU4 is taken as CU1 respectively. If the control unit CU1 is in failure, the failure detection relay of the changeover unit CH1 is activated with the self- diagnostic circuts SD1 and the control variable B1 is controlled with the output of the control unit CU4.
