Removing points from data collection

AVEVA™ PI System Connector 3 (PSC3) continues data collection for PI Points associated with the Replicate Data Archive only data sources, until those PI Points are no longer associated with any Replicate Data Archive only data source. These PI Points are no longer associated when you remove the corresponding PI Point queries from the Include PI Points that match this query field or remove the matching Replicate Data Archive only data source.

After these PI Points are removed from a Replicate Data Archive only data source, their data will no longer be collected. PI Points associated with a Replicate AF and Data Archive data source continue to have their data collected even after the associated data source configuration is deleted. These PI Points remain in the local point definition cache.

If it is necessary to clear the point definition cache and equivalent caching on the connector, stop the connector before touching any persisted files. If the persisted files are removed, the connector is wiped clean with no record of what has been previously sent. This may also cause a resync of the source AF data sources, as well as trigger history recovery for all PI Points as the local point definition cache is rebuilt

Note: These files should not be manually modified. If you attempt to manually modify them, it may result in severe data loss. If you require assistance with the cache files, contact AVEVA Technical Support.
