Abstract:
    To provide a control system and a controller for increasing an input/output device with simple configurations. The control system is provided with a first serial transmission line 300a for uni-directionally transmitting monitoring information for monitoring external equipment from a main controller 100 to input/output devices 200a, 200b and 200c in the order of the designation of input/output ports 70a to 75c, and a second serial transmission path 300d for uni-directionally transmitting control information for controlling the external equipment from the input/output devices to the main controller in the order of the designation of the input/output ports. Furthermore, the main controller 100 and the plurality of input/output devices are annularly connected through one or more third serial transmission paths 300b and 300c for connecting the plurality of input/output devices 200a, 200b and 200c and the first serial transmission line and the second serial transmission line.
