Hey all,
I am pulling some tags from a Kepware server connected to a Siemens S7-1500 PLC, after a recent Ignition update to Version 8.1.33 one of the tags will go to "Uncertain" and not report any values from the PLC while the other tags continue to get values back just fine:
If I edit the UDT and change the path to the tag slightly to an incorrect value and then edit again and fix the path then the tags will start pulling in the correct value from the Kepware server and it will work fine for another couple of days. After that it will go back to Uncertain and I have to do this over again. I tried putting this tag into a different scan class but that did not make a difference. This is literally the only tag on the server that has this problem. Is there anything I can check in any logs or anything to figure out a root cause? Since it was working fine before the recent Ignition gateway update I'm assuming it's some type of bug.
