摘要： PROBLEM TO BE SOLVED: To provide a new line switching device for suppressing damages to a line fault, to a minimum, improving the availability, and enhancing cost-effectiveness in the system as a whole, and to provide a plant control system which uses the device. SOLUTION: The line switching devices corresponding to each input/output device are arranged in order to control the plurality of input/output devices with the use of a single CPU. An ID is imparted to each line switching device. An ID for uniquely identifying the line switching device is embedded in a data frame to be transmitted from the CPU. By having the line switching device allow only the data frame with IDs matching to pass, collisions of the data frames, which occurs when the data frame improperly comes-in to a control line, are avoided.
