摘要
由于电除尘器的高压设备和称重设备只带RS422/RS485的接口,为了能与iFIX的通讯,需利用OPC协议创建OPC服务器来实现。以试验除尘器控制系统为例,探讨了OPC协议在该系统中的使用方法。
The high voltage energisation and weighing functions is only have RS422 /RS485 interface.In order to communicate with iFIX,it need to use OPC agreement to create OPC server.Based on the Trial ESP control system as an example,discusses the OPC agreement in the system of using method.
