基于S7－400 PLC的污水处理控制系统

摘要

The application of sewage treatment control system based on Siemens S7-400 PLC is presented by example. The hardware selection, the network structure and the monitoring interface configuration of the system are discussed respectively. The system has high automation degree, and can save the cost and improve the processing efficiency of the sewage treatment.%以某污水处理控制系统为例，讨论了S7－400 PLC在污水处理领域的应用，分别对系统硬件选型、网络结构及监控界面组态进行了说明。该系统由于自动化程度高，节约了污水处理成本，提高了污水处理效率。
