PROBLEM TO BE SOLVED: To provide a network control system in which a network having a multiplexed structure and a branched function together is easily constructed and the network is automatically reconstructed in the case of abnormality. SOLUTION: In the network control system wherein a host controller and a plurality of communication interface circuits 10-1 to 10-N are cascade connected by signal tables and input/output equipment is connected to the communication interface circuits 10-1 to 10-N via input/output interfaces, two or more systems of input and output terminals are provided in each of the communication interface circuits 10-1 to 10-N, the input and output terminals are connected by independent signal cables, and each of the communication interface circuits 10-1 to 10-N is equipped with an input priority circuit for preferentially receiving an input from a specific input terminal in the input terminals.
