摘要
该文在理解城市污水处理工艺的基础上,采用GE的PLC构建控制系统,在其特有GENIUS网络通讯协议下,利用RS-485现场总线实现主从站模块之间数据交换,从而实现厂区设备的自动化控制。
In this paper,on the basis of understanding the wastewater treatment technology, uses GE＇s PLC control system construction to build the control system,and use the RS-485 fieldbus master and slave data under the GENIU network protocol to exchange between modules to achieve plant equipment Automation and control.
