Hello All,

I would like to know if compression can be applied when backfilling data using PI UFL interface. We have to backfill data from another historian, and have the data in csv format. The csv extract has events at very high frequency and we do not want all the events to be stored in PI.


I have the PI tag configured to have compdev and excdev values. However when tried to upload the data through ufl interface, all the events from the input file were archived. Can you let me know if compression can be achieved and what are the settings to be configured in the PI tag or the interface to achieve the same.
