Possibly be able to tie it to an action item. This would be nice so I could put an entry on the HMI for a supervisor to determine how long they want to keep records for.
You could ‘roll your own’ delete-older-than group pretty easily.
All it would be is an action item than ran a DELETE FROM TABLE WHERE t_stamp >= {…}, where the something part is dynamically generated based on some user-settable data.
That said, having it built in would certainly be more convenient.
Thanks for the tip. I guess it isn’t really necessary then, but it sure would be convenient
