A Trend view is based on a number of points. That maximum number is 999 points. (So that is an indication for the timespan you see) Because it is based on the cycle you are "logging" data. How faster you are "logging" how more points are used. (Timespan will be shorter) Best regards, Wizard

If the "Timer interval" is set to 1000 sec, for example, that would be very close to 20 minutes. While your archive would indeed log for a very long time, only a brief section of it would be displayed. Cheers, syzygy
