Study And Design Of Wet Resin Batching System Based On PLC And WinCC

The production process of the wet resin batching system is very rigorous.According to the production processes of the system and the actualrequirements,the main control program is determined to be DCS control system.Combined with the control objects and control requirements,the hardwarecircuit is designed. Hardware circuit includes the motor drive circuit and controlcircuit.S7-300PLC as the control center and configuration software WinCC as theHuman-computer interface. PLC and WinCC achieve communications by industrialEthernet. Achieving the operation of the control objects so that completing theunloading process.In order to make the system more secure and reliable,it not only designs theautomatic way, but also designs the manually way. it can manually stop when theautomatic production way failure. If errors exist, operator can manually modifythem.This control system is very advanced in the chemical industry. The productionprocess achieves automation and modernization. This design makes the chemicalproduction achieving large quantities, it also improves the quality of the productand the production efficiency of the enterprise.
