Adding a pc name/ip address to the following call should allow me to access the CCMcpAut component from a remote pc [code]System.Type oType = System.Type.GetTypeFromProgID("WinCC-Runtime-Project", "192.168.0.1", true);[/code] Running my c# application on the same machine as wincc, then it works (using both 127.0.0.1 and 192.168.0.1). But despite disabling the firewall, and setting permissions on the component via regedit and/or dcomcnfg, i cannot get it to work. Anyone experience with this? (btw i am aware of the alternative OPC server)

If you run the example on another PC you have to install at least the MCPAuth OLE-Server component from WinCC. regards cookie

I know, it's about OLE not OPC Cookie If you run the example on another PC you have to install at least the MCPAuth OLE-Server component from WinCC. PC A:(192.168.0.1) running winCC 7 + CCMcpAut component PC B:(192.168.0.2) c# application that tries to connect to the CCMcpAut component running on PC A running the c# app on PC A works just fine... Do you mean that i have to install the CCMcpAut component on PC B? Something that i cannot imagine since the component running on B is not aware of PC A.

joost Posts: 12 Rating: (1)	unfortunately this isn't solved, i use this workaround: insert the data from PC B into a database on PC A on the wincc machine (PC A) i read the data and locally connect to the wincc OLE object today I got an answer from the development department: The access to WinCC Runtime object is only possible on local PC. WinCC must be installed on PC you want to use the connection via OLE object.
