The event details page shows the process behavior of an event's attributes inside a trend and tables. From the event details page, you can analyze, acknowledge, and annotate critical events.
You can not save an event details page for future access the way that you can save displays. However, if you want to directly access a certain event details page in the future, you can copy the URL that appears in your browser's address bar when you have an event details page open. For more information, refer to Event Details URLs.
Note: From PI System Explorer, PI administrators grant permissions to acknowledge and annotate events (PI AF version 2016 or later is required). For more information, see the AVEVA PI Vision administration topic Set permissions to allow users to acknowledge and annotate events.
