I upgraded to 4.2.10 over the weekend. This morning I went to check to make sure things are working correctly, and they’re not. I figured the differences I was seeing over the weekend were due to using polled reads on certain groups, which according to you guys, didn’t work correctly for me until this version because I’m using OPC server v2.
I think I may have the issue narrowed down. It doesn’t make any sense, but I think I finally figured out what’s going on.
If a tag is in a group using “polled reads instead of subscriptions”, we’ll call this Group A, the value of that tag doesn’t update anywhere else in FactorySQL until Group A updates.
I’ve verified this by turning off all the “polled reads” groups. Suddenly tags started updating again in other groups.
This is really messing with my system right now. Please help.
