It works just fine(in trend), but I have a little question, and I hope that You can help me. My problem: I made a 2 internal tags, just to make shure that works, and the third tag is sum on previous 2 tags. For trend, script works, but I did put a IOFiled for the same (third) tag, and change in the IOField happens only when I go in another picture and go back in the previous picture(in picture where is that IOFiled). My question is: how to make IOField show the same value as trend, so I don't to need to refresh picture. Best regards, Srdan referred thread: Tag scaling on trends

Srdan Posts: 3 Rating: (0)	Hello, I put a Update cycle to "upon change". Problem is same. But I found a solution. I put a script in to Global Script-> Global actions, and added in Info/Trigger->Timer->Cycle, one tigger for 250 ms, and in "Tag" - tag which is sum of previous two(it will be triggered every 250ms). It works fine. now my question is: I have about more than 100 simular mathematical operation which I will call every 250 ms, so if I put all this operation, is it going slow down my project in WinCC, and all visualization?
