Hello.
I do not quite understand the question, and also what is the reason behind asking it.
For start, if I just took the question literally, the answer would be simple:
opcda://localhost/Kepware.KEPServerEX.V5
Maybe that is what you were asking for. But I feel I need to add some explanation. In QuickOPC, the OPC (COM) server is always internally specified using the ServerDescriptor object. And in it, there are some truly critical properties, such as MachineName for the name of the computer, or ProgId for identification of the OPC server.
You *can* use the "OPC URL" string instead, and assign to ServerDescriptor.UrlString property. But all that it will do is that it will parse it, and then fill in the above mantioned properties. From that point on, the URL is no longer used. So, setting the UrlString to the string I gave as an example is equivalent to setting the MachineName to "localhost" and the ProgId to "Kepware.KEPServerEX.V5". Also, if you use some QuickOPC methods that take separate machineName and serverClass arguments, again what that does internally it is that just constructs the ServerDescriptor with these properties. So we are just talking about different ways of constructing or deconstructing the server information contained in the ServerDescriptor. But the URLs do not provide any additional functionality that would not be achievable otherwise.
Regards
