To add SystemHistoryImportTags

1. Drag the SystemHistoryImportTag from the exportTags palette anywhere in the station’s Config space (you may wish to create a separate folder just to hold these tags).

   The Name dialog appears. Either accept “SystemHistoryImportTag”, or enter another name and click OK. By default, this is the name of the NiagaraSystemHistoryImport descriptor created in the Supervisor.

2. Double-click the SystemHistoryImportTag 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. In the System Tags Pattern property (last property listed in property sheet), enter one or more System Tags, as used in history extensions in the subordinate (JACE) station. For related details, see the section “Using System Tags to import Niagara histories” in the Drivers Guide.

4. Most remaining properties of the SystemHistoryImportTag are standard to Niagara system history import descriptors, noting briefly:

   • History Import Name — name of the NiagaraSystemHistoryImport descriptor, where the default format variable results in the same name as the export tag itself.

   • 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 histories imported by this tag will have any export tag category filters applied to them (default is true).

     For this export tag type, this feature is future use only—currently, only histories exported using the HistoryImportTag can make use of the category mask feature.

5. Click Save after finishing all property changes.
