Abstract: In view of the fact that there is no intelligent monitoring device in the existing sewage treatment process, this paper proposes using Siemens S7-300 series PLC as the core controller of the sewage control system. This paper also designs the PLC multi-computer communication based on the Profibus communication protocol, and the field bus sewage treatment control system based on the communication between the main controller and the power meter based on the Modbus protocol. Finally, a sewage treatment control system based on fieldbus is built, and the designed system is applied to the control process of sewage treatment in the CASS process, which greatly reduces the labor intensity of workers and the cost of sewage treatment.
