Table 10-2: HART variables and transmitter outputs
HART variable Reported via Comments
Primary Variable (PV) Primary mA Output If one assignment is changed, the other is changed
automatically, and vice versa.
Secondary Variable (SV) Secondary mA Output, if
present on your transmitter
If you have a secondary mA output: If one assignment is
changed, the other is changed automatically.
If you do not have a secondary mA output: The SV must be
configured directly, and the value of the SV is available only
via digital communications.
Tertiary Variable (TV) Not associated with an
output
The TV must be configured directly, and the value of the TV
is available only via digital communications.
Quaternary Variable (QV) Not associated with an
output
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.
Configure HART burst messages
ProLink III
Device Tools → Configuration → Communications → Communications (HART)
Field communicator Configure → Manual Setup → HART → Burst Mode
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.

1 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).
