Hi there,
I could see different possible ways to limit the database size on a LabVIEW DSC system.
a) You could limit the lifespan of your logged data to a certain time by adjusting the option 'Days to keep historical data' in the Tag Configuration Editor>Configure>Historical... tab.
b) You could use the Citadel Database VIs. Archive Database.vi would allow you to archive a database or a part (certain traces/tags, or certain time interval) to another location. With the archive option 'destructive', it would delete the source of the data from the original database.
Delete Traces.vi would delete a traces from a database.
c) The same/similar functionality you can have throught the Measurement and Automation Explorer and its Historical Data Viewer plug-in
.
b) and c) are NEW features of LabVIEW DSC 6.1!
Hope this helps
Roland
