To adjust the port for the OPCSystems.NET OPC Server modify the file DANSrv.exe.config in the directory C:\Program Files\Open Automation Software\OAS\ with Notepad or a text editor.

Set the properties TCPPortNumber and WCFPortNumber to the desired TCP port number. The default is 58727.

<add key=""TCPPortNumber"" value=""58727""/>
<add key=""WCFPortNumber"" value=""58724""/>
