摘要：The PLC communication system associated with the invention is characterized inthat the system comprises a programmable logic controller (PLC), a plurality ofprocessing devices (150, 250, 251-258), at least three communication processing nodes

(41, 140, 240,241-248) provided at the PLC and at the plurality of processing devicesrespectively to establish communication of the PLC and each of the processing devicesand an interconnecting device (HUB) and a plurality of communication lines (120, 220, 121-139, 221-236) for connecting the communication processing nodes with one another toestablish data communication among the communication processing nodes. The PLCdetects a state of communication failure and a display device displays an abnormalportion (114, 128, 230, 216) in a communication route based on the number of

occurrences of the state of communication failure in respective interconnecting deviceand plurality of communication lines.
