View event details and annotate events

Use the event details page to analyze, acknowledge, and annotate critical events.

Note: To acknowledge and annotate events (to share comments and attachments related to the event with your colleagues), you require permission, granted by the PI administrator in PI System Explorer. Without proper permission, you can only view comments.

1. In the Events pane, right-click any event in the list and then click Event Details to open the event details page.

   You can also open the event details page from the event-comparison page.

2. To view event details for another event, click a different event on the list.

3. Use the collapsible tables to add or remove attributes to and from the trend.

   1. To add an attribute to the trend, click the row containing that attribute.

      The row will be highlighted, and the attribute will appear on the trend.

      Note: Only attributes containing numerical data, with rows marked with a trend icon , can be plotted. If the event attribute is a summary operation (Average, Min, Max, and so on), then the source attribute will be plotted, not the summary value.

   2. To remove an attribute from the trend, click the highlighted row containing that attribute.

   3. To highlight the trace of an attribute on the trend, hover your mouse over the attribute in the table.

4. To acknowledge the event, click Acknowledge.

   An acknowledgement is posted under Actions and Comments with your name and the time of acknowledgement.

   Acknowledgements cannot be deleted or reassigned and are stored on the PI AF server.

   

5. To add a comment, enter the comment in the Add Comment field and click Add.

   

   The comment is posted under Actions and Comments with your name and the time of the comment.

   Note: The text limit is 2500 characters.

6. To attach a file, click the Attach button under the Add Comment field, browse to your file, click Open, and then click Add.

   The attachment is posted under Actions and Comments with your name and the time of attachment.

   Note: By default, the maximum file size for an attachment is 7 MB. Allowed file types include CSV, DOCX, PDF, XLSX, RTF, TXT, GIF, JPEG, JPG, PNG, SVG, and TIFF. Maximum file size and allowed file types can be configured by the PI administrator in PI AF version 2016 and later. For more information, see the AVEVA PI Vision administration topic Change event annotation file types and size limits.

7. If desired, set or change the reason for the event:

   • To clear the current reason, click Clear and then click Apply.

   • To set a new reason, select the reason from the list and then click Apply.

8. To return to your display and exit the event details page, click the Back button.
