Data archive PI point selection

AVEVA™ PI System Connector 3 (PSC3) supports the Replicate Data Archive only data source configuration option. This option requires the user to enter a query in the PI Point Queries field to define the PI points desired for data collection for the Data Archive selected in the configuration. To reduce query complexity, multiple Replicate Data Archive only data source configurations can be defined for the same source Data Archive to achieve the desired PI points for data selection.

Note: PI Points that appear in several data source instances are replicated just a single time. Data sources that overlap will not lead to the creation of duplicate PI Points.

If PI Point data is referenced within an AF database that is associated with a Replicate AF and Data Archive data source, that PI Point data will be always replicated. This is true even if other data sources contain PI Point queries that exclude that PI Point data.
