To add HistoryImportTags

1. Drag the HistoryImportTag from the exportTags palette onto the point’s history extension, or if desired, onto its child HistoryConfig extension (either location is acceptable).

   The Name dialog appears. Either accept “HistoryImportTag”, or enter another name and click OK. Note by default, the resulting Niagara history import descriptor uses the parent name of the history extension, and not this name.

2. Double-click the HistoryImportTag to access its property sheet.

   1. In the Supervisor Station property, click the control and select the Supervisor station, then click Save.

   2. For Station Slot Path, either accept the default “slot:histories”, or else either:

      • Enter a slot path to use on the Supervisor station for the Niagara archives folder to hold this history import descriptor. Note the entered property value must begin with slot:histories Note “BFormat” variables are an alternative too. See Station Slot Path considerations for more details. Or, (if desired) use the station “profile.bog” file method”, described next.

      • Or, click open folder, for the Select Parent Target dialog. Expand the niagaraStation and select a target container under Histories for the Niagara history import descriptor to appear in the Supervisor station (default “slot:histories” puts the import descriptor in the root of the Histories extension).

        You may edit the “profile.bog file” to specify a new target folder structure—see Verify and edit the station profile.bog file for details.

3. Most remaining properties of the HistoryImportTag are standard to Niagara history import descriptors, noting briefly:

   • History Import Name — name of the NiagaraHistoryImport descriptor, by default set using a format variable, resulting in name similar to: “Remote_pointName”. Does not affect history name.

   • Execution Time — standard selections for a Niagara history import.

   • Config Overrides — standard selections for a Niagara history import, containing settings for Capacity and Full Policy.

   • On Demand Poll (Enabled and Frequency) — standard selections for a Niagara history import. For related details on these four properties, see “History Import Edit” in the Drivers Guide.

   • Use Category Mask — Boolean to specify whether the history imported by this tag will have any export tag category filters applied to it (default is true). For related details, see CategoryFilters.

4. Click Save after finishing all property changes.
