摘要
针对工业控制系统中存在的系统集成难题,提出利用OPC技术,采用模块化结构设计并开发符合EPA标准的OPC A&E服务器,最后利用客户端测试A&E服务器,结果表明该服务器可以为现场设备和上层监控软件提供开放式的标准接口,解决系统集成难题,并使得工控软件可以按照统一的标准有效的处理现场各种报警事件,提高工业生产的安全性,预防严重事故的发生。
This paper introduces the OPC technology based on EPA industrial Ethernet. A modularized OPC A＆E server according to the EPA standard is also presented. The experimental results taken by client test program are given, and it shows that the server can offer an open standard interface between the field devices and the supervision software.
