I would like to keep tag history at a fast rate for a short time (1 second intervals for 1 week), and the same tag at a slower rate for a longer period of time (30 second intervals for 1 year). This will allow detailed analysis of recent events, and still provide the needed information for older data, while not taking up too much hard drive space for the older data.
I’ve had a look at the Tag History Splitter, but it uses the same scan class for both recordings.
I’ve also considered Transaction Groups, but it’s a bit cumbersome to set this up for the number of tags I’m looking at (about 1,000 tags).
Can anybody suggest a good solution?
