The manual states that the parameters are read/write, but as far as I can see they are read-only in Visual Studio. See screenshot. Attachment Screenshot.png (177 Downloads)

The objects themselves have read access only, but they contain parameters that are read/write. Those parameters are not described in the manual. Here is how it does work: // Set parameters dataLog.Settings.LogMaxSize = 1000; dataLog.Settings.LogTimePeriod.Days = 730; dataLog.Settings.LogTimePeriod.Hours = 0; dataLog.Settings.LogTimePeriod.Minutes = 0; dataLog.Settings.LogTimePeriod.Seconds = 0; dataLog.Segment.SegmentMaxSize = 100; dataLog.Segment.SegmentStartTime = DateTime.Now; dataLog.Segment.SegmentTimePeriod.Days = 1; dataLog.Segment.SegmentTimePeriod.Hours = 0; dataLog.Segment.SegmentTimePeriod.Minutes = 0; dataLog.Segment.SegmentTimePeriod.Seconds = 0;
