I am now trying to develop an OPC Client using Borland Delphi. Unfortunately I can't find any explanation on the typical process the OPC Client uses to do the following:

- Connect to the OPC Server
- Add Groups and maintain their link

Any information regarding how the interfaces should be used (i.e., in what order should they be created) would be a great help.

And i would be grateful if you send me some examples of OPC clients on Delphi.
