Does anybody know how to get rid of that line (without changing the trend time settings to UTC)? Dec

Double-click on the trend and go to the Limit Values tab. You can then set a different colour for both DST hour changes, the Time Overlap and the Time Jump. I hope this helps.

Danielle Posts: 1275 Rating: (123)	At least in C you can choose wether or not to display TimeJump, TimeOverlap and Replacement values. (Time Jump happens would happen, for instance, when you setyour clock1 hour further, for daylight savings time, so there would be no values for that hour.Time Overlap would happen when you set your clock 1 hour back, so there would be 2 values for the same time) SetPropBOOL(Screen_Name, "Trend_Control", "TimeJump", FALSE); SetPropBOOL(Screen_Name, "Trend_Control", "TimeOverlap", FALSE); SetPropBOOL(Screen_Name, "Trend_Control", "Replacement", FALSE); You can also change their colors, in case you choose to display them: SetPropWord(Screen_Name, "Trend_Control", "TimeJumpColor", CO_DKGREEN); SetPropWord(Screen_Name, "Trend_Control", "TimeOverlapColor", CO_DKGREEN); SetPropWord(Screen_Name, "Trend_Control", "ReplacementColor", CO_DKGREEN); Remember that if you choose not to display those values, there will be nothing in your trend at that time. We've had a case in which a customer called us, thinking WinCC was having problems, 'cause he couldn't see the values. In his case there was a network problem, which caused the values to be uncertain. (Replacement values) Best regards, Danielle

Danielle Posts: 1275 Rating: (123)	But as I said, you must remember that by not showing them you'll get a blank in the trend control. We've had customers who asked for them not to be displayed, but as a default we change their colors (if the trend is yellow, the replacement / time jump / overlap value is dark yellow). [:P]
