Restriction
This feature is available only with a HART 7 host.
Procedure
1. Enable event notification.
2. Select all desired alerts.
If one or more of the selected alerts occurs, each active burst message will broadcast HART Command
119 until the alert is acknowledged by a HART master.
3. Set
Trigger Interval
as desired.
Trigger Interval
controls the delay before HART Command 119 is broadcast.
•
Default: 0 seconds
•
Range: 0.5 to 3600 seconds
Trigger Interval
begins when the transmitter detects the alert condition. When
Trigger Interval
expires:
•
If the alert is still active, HART Command 119 is broadcast.
•
If the alert is not active, no message is broadcast.
Tip
If you set
Trigger Interval
to 0, HART Command 119 is broadcast as soon as the alert is detected.
4. Set
Retry Rate
as desired.
Retry Rate
controls the rate at which HART Command 119 is broadcast when event notification is
active.
•
Default: 0.5 seconds
5. Set
Maximum Update Time
as desired.
Maximum Update Time
controls the rate at which HART Command 119 is broadcast when event
notification is not active.
•
Default: 60 seconds
