Alarm Analysis Meta Tags

The KPIs and metrics that make up the Alarm Analysis reports can be queried via meta tags, meaning Alarm Analysis data can be queried and visualised just like any other process data source. A good example of this is Power BI, where you may wish to create a bespoke Alarm Analysis report combined with other data sources.

For a full list of meta tags, refer to the Industrial Connector Help Page

Not all Meta Tags are Discoverable

While Power BI allows free text entry when configuring data queries, others apps such as Gestalt PnID and Trend restrict users to a “search and select” dialog. Generally, this makes UI interaction simpler, however “meta tags” are not constructed like regular tags and may not be available for search. Some meta-tags are dynamic and hold parameters which are interpreted by the Alarm Analysis data source.

For example,

Oil Co/Osprey/ALM BA report/3.priority

This above meta tag requests the priority of the 3rd most frequently occurring Alarm on the Oil Co Osprey asset. Clearly this is not a value you would expect to interrogate like a regular process data tag, however there may be cases where it is required.

If explicit tag entry is not permitted in an app, and the meta-tag is not available in search, it can be manually added to the Alarm Analysis Tag Index. For more information, refer to: How to add a "Meta Tag" to an Alarm Analysis Tag Index
