Source tab options

Use the Source tab to specify the data version and type of table for the query.

To configure the source

• In the Source area, specify the AVEVA Historian tables from which data will be retrieved.

  • Manual history tables: Normal SQL Server tables that are used to store data. These are the ManualAnalogHistory and ManualDiscreteHistory tables.

  • Extension tables: Logical tables that are populated from the AVEVA Historian data files. These tables support the AVEVA Historian time domain extensions for handling data.

  • Both: Select this option to retrieve data from both the manual and extension tables.
