摘要
西门子PLC S7-300通讯,在其基础上重点结合污水处理的实际工程,通过3台PLC之间的通信完成污水处理工程,本文具体介绍了通信设置及连接。3台PLC分为一主一从一独立,采用PROFIBUS进行通信,通过设置及编程完成通信。同时设有仿真实时监控界面及通信配置界面,真正做到PLC与PC机,PLC与PLC之间进行实时通信,完成工业现场的实时监控、操作,可以达到工业现场稳定、快速、精确的标准。使工控过程在顺畅的通信中完成安全稳定运行。
PLC S7-300 communications, Siemens, on the basis of the combined wastewater treatment on actual engineering, through the communication between the three PLC finish sewage disposal engineering, introduced concretely communication Settings and connection. Three PLC into a main from an independent, communicate using PROFIBUS by setting and programming, complete communications. Meanwhile equipped with simulation real-time monitoring interface and communications configuration interface, achieves truly PLC and the PC and PLC and PLC real-time communication between complete industrial site, the real-time monitoring, operation. Can achieve industrial site stability, fast, accurate standards. Make the smooth communication process control in the safe and stable operation of completion.
