In order to improve the safety and reliability of the entire system of the adhesive plant, the plant's equipment was retrofitted in this design. This design is based on the reactor as the main object of control, the main controller is AB Controllogix type PLC L72. The communication network adopts high speed control Net control network. In the main communication protocol of the system, Ethernet / IP high-speed Ethernet communication is the main way. In addition, Wonderware Intouch is used as the host computer interface software. At the same time, in the RSLINX network configuration, OPC is used as the middle end of the service, thus interacting with the seamless connection of the lower computer data. Finally, EXCEL is used as a server for intermediate exchange of data in order to view historical data. Therefore, this design can not only ensure the safety of the entire production line, but also has the advantages of high reliability, low cost, low power consumption and good man-machine interface.
