Automated data collection for utilization and OEE metrics

The AVEVA Insight Performance feature allows you to configure automated data collection for the following:

• Utilization reasons

• Production counters

• OEE data properties

• Production runs

To configure automated data collection, you assign one or more AVEVA Insight tags to each automated piece of equipment. When a tag value changes at run time, the change causes various state changes and transactions in the Performance run-time system. These state changes are visible on the Asset, Equipment Efficiency, and OEE Analysis pages.  

Note: It is strongly recommended that you use only tags with a data change trigger, and not a periodic trigger. This will optimize system throughput and database query response time by minimizing the logging of unnecessary data.

The tag values can come from an Historian Publisher—the recommended approach—or by uploading a CSV or JSON file.

Note: During automated data collection, note that tags that are older than 30 days are ignored.

The tags are assigned to equipment in the efficiency model. Tag entries in the model are fully qualified names (FQNs). The FQN includes the data source as the first tag component and the tag name as the second component, separated by a period (for example, Austin.Capper1.UtilReason).

For production counter tags, the configured tag reference is case-sensitive. It should match the case of what is entered in the AVEVA Insight tag dictionary.

For more information about data sources and tags, see Set up and manage data sources and Manage the tag dictionary.

Note: The AVEVA Insight Total retrieval mode is not applicable for KPI tag values whose unit of measure is percent (%). If the Total retrieval mode is applied to KPI tags whose unit of measure is counts or minutes, the sum of the recorded hourly values might be different than a single calculation performed for the select time period (e.g., number of downtime counts from 8:00 am to 9:00 am = 4, number of downtime counts from 9:00 am to 10:00 am = 3 … and number of downtime counts from 8:00 am to 10:00 am = 6).

Equipment efficiency tag data is updated at the top of every hour.
