(About 15 curves of 1000 points.) Hi have found this topics by DENILSON but it requires using a login tag and these are a paid option. WinCC Unified – Simple Sample - Inserting noncyclic real time information to Function Trends (X Y trends) - 249663 - Industry Support Siemens With Wincc Comfort/Advance there was a dedicated Trend tool for this, With Wincc Pro TIA I did this with a VB script. With Wincc Unified there is no dedicated Trend tool and I can't write a 100% functional and responsive script. I need to refresh my 15 trends every 3-4 seconds. Do you have a working script that doesn't use a login tag?
