I was wondering if it is possible to hold tag data for a duration of time. For example, I would like to hold a value from 8:00 to 8:10. Once 8:10 comes around, I would like to start receiving data again.
How are you getting your data? Is it via an OSIsoft interface or ?
I'm receiving data via a PI interface
Do you want to hold this value in a regular fashion, i.e. 8:00-8:10, 8:10-8:20, 8:20-8:30 (1 value every 10 minutes), or is this just a one time basis? Perhaps it would be easier if you can describe your use case in more details.
Please also let us know what PI Interface you are using. As soon as we understand what you like to achieve, we may have to consult the interface manual and seek for options.
One more question: would you like to hold tag data for a particular tag / several tags / all tags from this interface?
