PI point edits

AVEVA™ PI System Connector 3 (PSC3) supports PI point edits on the source PI System. As a result, an edited PI point that currently collects archive only data may have been modified to collect snapshot data or vice-versa. In this case, PSC3 removes the PI point from its current data collection mode and place the PI point into the backfill mode. After backfill is complete, the PI point is placed into the appropriate data collection mode and resume data collection.

Note: It is not uncommon for PI users to make modifications to PI points, especially when determining appropriate compression settings. AVEVA recommends that data collection for PSC3 be stopped before making bulk edits to PI points, particularly when changing the compressing attribute.

After PI point edits are complete, restart data collection for PSC3. This allows PSC3 to operate most efficiently during restart operations and PI point edit handling of replicating PI point configuration from source to destination PI System. The restart of data collection allows for more efficient configuration of the snapshot and archive data collection objects within PSC3.
