Batch Framework Interfaces - Officially support fanning tag data to a PI Collective
Unlike other PI interfaces, the Batch Framework Interfaces do not use buffering. If the interface loses connection to the PI Data Archive, the interface continues collecting data and stores it in its local cache. The PI Batch Database is primary-only so it did not make sense to fan data to other PI Collective members. However, this is no longer a consideration if Event Frames are being written. There should be an officially tested and supported way to fan tag data to a PI Collective.

It would be a great improvement for us too.

Makes sense - I had a mfg site decline to implement a collective at first because they might be missing batch data if looking at the secondary server in the collective.

We could definitely use this... that way my users won't have to worry about "missing" data when they are looking at the other collective members!!

Writing tag data to secondary PI server via Batch Interface would be very helpful for us too!
