The problem: consider two process tags tag_X and tag_Y representing some process parameter (e.g. liquid level, temperature, ..). A HMI running WinCC is being used for value display and trending of these. The required tag archiving regime is: 1 record every 1 second when some condition is true, but at 1 record archived per minute when the same condition is false. Additionally, a separate condition provides a flad whose value indicates whether archiving should be done at all or not.
Any ideas how this can be achieved in WinCC without creating duplicate archives?
