Currently I'm trying to exchange data with the RSLinx OPC server writing the source code in Visual Studio, with the language Visual Basic or Visual C++.

I can "navigate" through the OPC variables without any problem, viewing the various items in a treeview form.

The problem is that the selection of the items must be manual. Each person must select the item (in the treeview) from which must exchange the data. The problem is that I can't create an OPC item because I can't check the specific item path.

Does anyone take a similar approach? Can anyone send me an example?

Thanks in advance.

 

Did you get the answer for this? I am trying to achieve something similar.
