摘要

PROBLEM TO BE SOLVED: To provide a multilayer control network system that can reduce the cost by saving man-hours and enhance the reliability of generating and setting a routing parameter. SOLUTION: In the multilayer control network system where controllers 1 each having a communication station and controlling a controlled object are connected to a network, a plurality of communication stations is provided for each control apparatus 1 and a plurality of networks is hierarchically connected, when a communication station of a communication request side on a network makes communication with a communication station of a communication destination on other network through the communication stations, the communication station requesting the communication and a plurality of the communication stations inquire of each communication station about the sequential communication paths up to the communication station of the communication destination and respectively set a communication routing parameter on the basis of the inquiry result.
