Events are important process, product, safety, environmental, and/or business time periods worth recording.
In the PI System, events are recorded using PI Event Frames.
Instead of searching by time, PI Event Frames enable users to easily search the PI System for the timeframes of a specific event type (ex. Find all Environmental Incidents in the last 30 days).
With PI Event Frames, the PI System helps you capture, store, find, compare and analyze the important events and their related data.
