PROBLEM TO BE SOLVED: To provide a logical operation processor for stably supplying a common clock, and for easily exchanging each system of a redundant system, and for securing the synchronizing precision of each system. SOLUTION: This logical operation processor is provided with a common clock information source 16 for notifying a common clock for setting the synchronization of a redundant system; a communication path housing part 15 for monitoring a communication path 12, and for sending common clock notification to the communication path 12 in a predetermined order while preventing collision, and for housing it in the communication path 12; a clock extraction part 6 for extracting the clock notification multiplexed on the communication path 12; and a logical operation processing part 17 for performing logical operation.
