But I add each trend in the control. How I can delete the actual trend displayed before display a new trend. I have no find this function in VBS. If I exit of the trend current view and go after in the trend view the control is "initialized" and may new trend is only displayed.

See the FAQ: "How do you provide new tags for the separate trends of an f(t) trend display by means of a C script or VB script in WinCC Runtime Professional?" with: Dim obj Set obj = ScreenItems("Control_1") obj.TrendName = "Trend1" obj.TrendTagName = "TestArchive\TagB" You can set an archivetag for the Trend1. with: obj.TrendTagName = "" you can set no archivetag for the Trend1.
