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
a BACK message until the event is acknowledged by a HART master using HART
command 119.
3. Set Trigger Interval as desired.
Trigger Interval controls the delay before the BACK message 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, the BACK message is broadcast.
• If the alert is not active, no message is broadcast.
Tip
If you set Trigger Interval to 0, the BACK message is broadcast as soon as the alert is detected.
4. Set Retry Rate as desired.
Retry Rate controls the rate at which the BACK message is broadcast.
• Default: 0.5 seconds

Overview
Modbus communications parameters control Modbus communications with the
transmitter.
Modbus support is implemented on the RS-485 physical layer via the RS-485 terminals.
Important
Your device automatically accepts all connection requests within the following ranges:
• Protocol: Modbus RTU (8-bit) or Modbus ASCII (7-bit) unless Modbus ASCII Support is disabled
• Parity: odd or even
