The screen capture is for a system history import descriptor. An export descriptor is similar with fewer properties. This type of descriptor does not use the
History Id. Instead, it uses theSystem Tag Patternsto configure which histories to transfer. - To create a single descriptor for the entire station, enter as many system tags as needed in the
System Tag Patternsproperty.For example, the
System Tag Patternsproperty in the screen capture configures the import job to include histories from history extensions with system tags that begin with the mnemonic: AHU, or that include these tags: Ltg1, Ltg3, or Ltg5. This configuration transfers histories from history extensions tagged with: AHU1, AHU_1, AHU2, and so on, as well as those tagged with Ltg1, Ltg3 and Ltg5. It excludes those tagged with: Ahu1, Ltg2, and Ltg 1.Other properties, such as
Execution Time,Capacity,Full Policy, andOn Demand Poll Enabledapply to the associated histories, and operate the same as for regular descriptors.Once set up, the data transfer occurs when scheduled by theExecution Timeproperties. - To manually import or export multiple histories, right-click its import or export descriptor and click .
