OPCServer Modbus使用和配置

一，安装KEPware.Enhanced.OPC.DDE.KEPServer。(PLC数据传送给KEPServer,开发的程序用OPCServer读KEPServer)

设置ip地址后面是指的plc站号，此处必须和plc上站号对应。否则无法接收数据。

打开quick client 查看传值情况

二.C#程序代码

引用opcdaauto.dll

在win7 64位下KepServer = new OPCServer()会出错的问题，

检索COM 类工厂中 CLSID 为 <28e68f9a-8d75-11d1-8dc3-3c302a000000> 的组件时失败，原因是出现以下错误： 80040154

1.一定要到C:\Windows\SysWOW64路径下打开cmd.exe运行命令文件（而不是在运行打开),注册“OPCDAAuto.dll” 输入命令: REGSVR32 OPCDAAuto.dll;即可

2.编译工具目标要选择x86

KepServer.Connect("KEPware.KEPServerEx.V4", "127.0.0.1"); 此处ip地址是安装KEPware.Enhanced.OPC.DDE.KEPServer电脑的ip地址.
