How do I set up PI AF notification rules?
How do I set up PI AF notification rules?
PI Notifications let you trigger alerts when AF analytics detect conditions like out-of-range values, equipment failures, or process deviations.
Prerequisites
- PI Notifications service installed and running
- PI AF Server with element templates and analytics configured
- Email (SMTP) or web service delivery channel configured
Creating a Notification Rule
- In PI System Explorer, right-click an element template and select Notification Rule Templates.
- Click New Notification Rule Template.
- Define the trigger condition — typically an AF analysis output (e.g.,
Temperature > 200). - Set the notification content — subject line, body with attribute substitution parameters like
%Element%,%Attribute:Temperature%. - Configure delivery — email, web service endpoint, or both.
Trigger Types
- On True: fires when the condition first becomes true
- On True for Duration: fires only if condition remains true for N minutes
- On Change: fires whenever the monitored value changes
Escalation
You can define escalation chains — if the first contact doesn't acknowledge within X minutes, notify the next person.
Best Practices
- Use On True for Duration to avoid false alarms from transient spikes.
- Keep notification templates in the AF Library for reuse across elements.
- Test with a small group before rolling out to production.
- Monitor the PI Notifications log for delivery failures.
