Abstract: This topic, which takes the experimental platform of train running as controlled object, constructs the DeviceNet Remote real-time supervisory system based on PLC. According to the requirements of train’s operation strategy, the design forms a train operation control system based on CQM1 PLC. By circuit designing, programming and debugging, this system achieved real-time monitoring for the running state of two trains’ preventing collision and route choice, etc; and then, through studying the DeviceNet, network monitoring system of host station based on CS1 PLC is established, and the supervision system is developed by the configuration software. After debugging, the design fulfills the Remote real-time supervisory system CS1 host station to the CQM1 slave station.
Key words: programmable logic controller; real-time monitor; configuration
