  • CitectSCADA 7.0

CitectSCADA project has defined the properties of the trend tags with a "sample period" larger than the (Extended Options) "Period" of the history file to be rolled over into a new file.

- Sample period = 96:00:00
- Period = 24:00:00


This is a configuration issue and needs to be corrected:

Change the "Sample Period" of the trend tag to a value smaller than the "Period" of the file to be rolled over, Or Increase the value of the "Period" file to be larger than the "Sample Period", and the Trend data is now saved correctly after shutdown and is displayed correctly in the Process Analyst after a restart.
