Event frame acknowledgement

In PI Asset Framework (AF) version 2016 and later, you can require that an event frame be acknowledged. The acknowledgment feature is used by notifications and PI AF client applications, such as AVEVA PI Vision. The event-frame acknowledgment feature replaces the acknowledge notification functionality in the legacy version of Notifications.

• For more information on setting up event-frame acknowledgment in notifications, see Learn about notification rules for analyses or event frames.

• For more information on viewing and acknowledging event frames using AVEVA PI Vision, see the AVEVA PI Vision user guide.

Security for event-frame acknowledgment

A user needs to have a PI AF identity for which the Annotate permission (an) is enabled. For more information on access rights, see List of access permissions.

Setup of event-frame acknowledgment

You set up an acknowledgment by selecting the Can Be Acknowledged check box as you configure an event frame template. Any event frame that is based on that template displays an Acknowledge link on the General tab. In event frames based on event frame templates where the Can Be Acknowledged check box is not selected, the Acknowledge link is inactive. You also cannot acknowledge event frames that are not based on an event frame template.

Note: The Can Be Acknowledged setting only affects event frames that are created after a template is created or modified.
