一，安裝KEPware.Enhanced.OPC.DDE.KEPServer。(PLC數(shù)據(jù)傳送給KEPServer,開發(fā)的程序用OPCServer讀KEPServer)

?????

???

?

??? 設(shè)置ip地址后面是指的plc站號(hào)，此處必須和plc上站號(hào)對(duì)應(yīng)。否則無(wú)法接收數(shù)據(jù)。

???

????? 打開quick client 查看傳值情況

?????

二.C#程序代碼

???引用opcdaauto.dll

?? 在win7 64位下KepServer = new OPCServer()會(huì)出錯(cuò)的問題，

?? 檢索COM 類工廠中 CLSID 為 <28e68f9a-8d75-11d1-8dc3-3c302a000000> 的組件時(shí)失敗，原因是出現(xiàn)以下錯(cuò)誤： 80040154

? 1.一定要到C:\Windows\SysWOW64路徑下打開cmd.exe運(yùn)行命令文件（而不是在運(yùn)行打開),注冊(cè)“OPCDAAuto.dll” 輸入命令: REGSVR32 OPCDAAuto.dll;即可

? 2.編譯工具目標(biāo)要選擇x86

?? KepServer.Connect("KEPware.KEPServerEx.V4", "127.0.0.1");? 此處ip地址是安裝KEPware.Enhanced.OPC.DDE.KEPServer電腦的ip地址.
