Automatic Control System of Sluice Based on PLC, MCGS and MODBUS Communication

In order to realize the integrated function of sluice management and control, S7-1200 PLC is used as the master control unit and S7-200 smart is used as the slave control unit. The load, opening degree, water level and other data of the sluice are collected through the special instrument, and the data is transmitted to PLC for storage and processing through MODBUS-RTU protocol. MCGS human-computer interface is designed, and data exchange with PLC through Modbus-TCP protocol is implemented, and the efficiency and intelligence of the sluice operation are greatly improved.
