I am currently doing a very similar project and I found this post really helpful! Thank you for this detailed guide.
However, I have come across a problem that I hope you could help me out.
I am currently using KEPServerEX v6 and Visual Components 4.2.2. I followed your tutorial step-by-step and I noticed that the tags I created however has a quality status of “Bad” as reported in the OPC Quick Client utility supplied by Kepware.
This has also further included issues to the pairing of variables. As “Bad” quality tags cannot be written/read in Visual Components, as an error will be given during simulation.
I would like to ask for help on how to create “Good” quality tags in KEPServerEX v6? I have fitted a few pictures as reference to my current situation.
In the Temporary Error tab of Visual Components said that maybe the Output panel would explain the error a little, however nothing is shown in the output tab.
If there are anymore further information you require, do let me know.
I hope you could help me out on this.
Thank you very much
