About licensing

For a point to be used by the Niagara Analytics Framework, it must be tagged with the a:a (analytics) tag. The system automatically compares the total number of points thus tagged with the allowed points on your license.

Be aware of these licensing-related factors:

  • When set to true, the AutoTagAnalyticPoint property on the AnalyticService causes the framework to automatically tag each new point with the a:a tag as required for use with the service. During initial station configuration, setting this property to true saves time. However, once the framework is configured and running in your Supervisor station, you should set this property to false.
  • If the analytics tag dictionary and a:a tag definition are missing from the TagDictionaryService, the AnalyticService tries to add them to the TagDictionaryService.
  • You can use a BQL scaler function in a platform’s Program service to query points with a specific tag (such as the a:a tag) and bulk edit them.
  • If you remove the a:a tag from a point, you must refresh cache to decrement the a:a tag counter. To refresh cache, right-click the AnalyticService and click Actions > Refresh Cache Full.
