HART variables and transmitter outputs (continued)Table 10-8:
HART variable Reported via Comments
Quaternary Variable (QV) Not associated with an out-
put
The QV must be configured directly, and the value of the
QV is available only via digital communications.
10.5.3 Configure burst communications
Burst mode is a mode of communication during which the transmitter regularly broadcasts
HART digital information to the network via the primary mA output.
Restriction
Burst communications, including trigger mode and event notification, are not available on HART/
RS-485. These features are supported only on HART/Bell 202.

Overview
Burst messages contain information on process variables or transmitter status. You can
configure up to three burst messages. Each message can contain different information.
Burst messages also provide the mechanism for trigger mode and event notification.
Restriction
If you are using a HART 5 host, only one burst message is supported.
Procedure
1. Navigate to the burst message you want to configure.
2. Enable the burst message.
3. Set Burst Option to the desired content.

Source (Primary Variable) Primary Variable
The transmitter sends the primary variable (PV) in
the configured measurement units in each burst
message (e.g., 14.0 g/sec, 13.5 g/sec, 12.0 g/sec).
