I wrote a VI, which worked perfectly.
After addressing the cFP from the network instead of from the PC, some Read tags gave Error 32812.
For one of them I deleted them and wrote them again, and the error was recovered. But then it appeared for another module.
From MAX I can perfectly read the channels. I also tried to "find items" again.
What could be the reason and the cure?
quite a few documents exist on your problem.
I'd start checking into them.
