Understand event frames in PI AF

Capturing important events in your process and collecting relevant data around those events can help analyze why they occurred. For example, you can closely monitor events such as asset downtime, process excursions, equipment startup or shutdown, and environmental excursions to identify possible causes or potential points of failure.

Collecting data around repeatable time periods such as product tracking batches, product runs, or operator shifts can help make those processes more efficient. The capture of comprehensive data associated with such an event helps track, compare, or analyze the process or event.

Just as elements allow you to collect and store data about assets, event frames allow you to collect and store data about events. It is recommended you use asset analytics to track your events using event frames. PI Datalink, AVEVA PI Vision, and PI WebParts are the client tools that support event frame visualization.
