Option Description
Continuous The burst message is sent at Default Update Rate. The burst interval is not affected by
changes in process variables.
Falling • When the specified process variable is above Trigger Level, the burst message is sent
at Default Update Rate.
• When the specified process variable is below Trigger Level, the burst message is sent
at Update Rate.
Rising • When the specified process variable is below Trigger Level, the burst message is sent
at Default Update Rate.
• When the specified process variable is above Trigger Level, the burst message is sent
at Update Rate.
Windowed This option is used to communicate that the process variable is changing rapidly.
Trigger Level defines a deadband around the most recently broadcast value.
• If the process variable stays within this deadband, the burst message is sent at
Default Update Rate.
• If the process variable moves outside this deadband in either direction, the burst
message is sent at Update Rate.
On Change • If any value in the burst message changes, the burst message is sent at Update Rate.
• If no values change, the burst message is sent at Default Update Rate.
3. Ensure that Primary Variable or Burst Variable 0 is set to the variable that will activate the trigger. If it
is not, reconfigure the burst message contents.
4. Set Trigger Level to the value of the process variable at which the trigger will be activated.
5. Set Default Update Rate to the burst interval to be used when the trigger is not active.
6. Set Update Rate to the burst interval to be used when the trigger is active.
Configure HART event notification
ProLink III
Device Tools → Configuration → Communications → Communications (HART) → Event Notification
Field communicator Configure → Manual Setup → HART → Event Notification
Event notification uses the burst message mechanism to indicate that an alert has occurred. When event
notification is enabled and one or more of the selected alerts occurs, each active burst message will broadcast
HART Command 119 until the condition is acknowledged by a HART master.
Prerequisites
If you are using a field communicator, you must enable a burst message before you can configure event
notification.
Tip
Event notification affects only HART burst messages. Whether an alert is selected for event notification or not,
alert severity, alert status (active or inactive), fault timeout, and alert acknowledgment operate as normal.
