Abstract PROBLEM TO BE SOLVED: To efficiently share control data across systems in a multiplexed control system.SOLUTION: In the multiplexed control system, a line concentration device 2a, which is provided for each system and connected to each calculation device 1a to 1c of the entire systems, is configured to relay communication frames between a calculation device 1a and an aggregation device 6. On receiving a communication frame transmitted and received between the calculation device 1a of the self-system and control target equipment 7, the line concentration device 2a transfers the received communication frame to a device of the identical system, and also transfers it to calculation devices 1b, 1c of other systems connected to the line concentration device 2a. Each calculation device 1a to 1c of each system stores communication data in the communication frame, received from the line concentration devices 2a to 2c of the self-system and the other systems, into memory means in the self-device.
