Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a multiplexing control device easily attaining mutual monitoring of a main system control device and a subsystem control device and configuration control functions such as a fault system suppression function, and to provide a multiplexing expansion board.SOLUTION: A multiplexing expansion board 12 expansively included in a control device having an arithmetic processing unit includes: communication means 121 for connecting another control device using a communication line; suppression control means 122 for suppressing arithmetic processing from the arithmetic processing unit connected to the control device; and monitoring means for transmitting a monitoring signal indicating that the arithmetic processing unit connected to the control device operates normally, to the other control device. When receiving an operation stop request signal indicating that the arithmetic processing unit connected to the control device operates abnormally from the other control device, the suppression control means 122 suppresses the arithmetic processing due to the arithmetic processing unit of the control device.
