PI Event Frames Generator (PI EFGen) generates events in the PI Asset Framework (PI AF) database based on values from trigger points in the PI Server. Using event frame templates in PI AF, PI EFGen populates event frame attributes from point data, handles complex hierarchical events and migrates existing PI Batch Generator (PIBaGen) configurations to event frames so you can continue to use your current batch structure.
PI Event Frames Generator 5.2.0, released October 2026, is a maintenance release addressing minor bug fixes.
For more information on product features and functions, including product features and functions, such as system requirements, upgrade, and installation instructions, refer to PI Event Frames Generator.
The latest information about the 5.2.0 release is available online on the AVEVA Documentation Portal.
