1.
Enable
Burst Mode
.
2.
Set
Burst Mode Output
.
Primary Variable
(ProLink II)
PV
(Field Communicator)
The transmitter sends the primary variable (PV) in the configured
measurement units in each burst (e.g., 14.0 g/s, 13.5 g/s, 12.0 g/s).
PV current & % of
range (ProLink II)
% range/current
(Field Communicator)
The transmitter sends the PV’s percent of range and the PV’s actual
mA level in each burst (e.g., 25%, 11.0 mA).
Dynamic vars & PV
current (ProLink II)
Process
variables/current
(Field Communicator)
The transmitter sends PV, SV, TV, and QV values in measurement units
and the PV’s actual milliamp reading in each burst (e.g., 50 g/s, 23 °C,
50 g/s, 0.0023 g/cm
3
, 11.8 mA).
Transmitter vars
(ProLink II)
Fld dev var
(Field Communicator)
The transmitter sends four user-specified process variables in each
burst.
3.
Set or verify the burst output variables.
• If you are using ProLink II and you set
Burst Mode Output
to
Transmitter Vars
(ProLink II), set the
four process variables to be sent in each burst:
ProLink→Configuration→Device→Burst Setup→Burst Var 1–4
• If you are using the Field Communicator and you set
Burst Mode Output
to
Field Device Vars
, set
the four process variables to be sent in each burst:
Configure→Manual Setup→Inputs/Outputs→Communications→HART Burst
Mode→Field Device Var 1–4
• If you set
Burst Mode Output
to any other option, verify that the HART variables are set as
desired.

The HART variables are a set of four variables predefined for HART use. The HART variables include
the Primary Variable (PV), Secondary Variable (SV), Tertiary Variable (TV), and Quaternary Variable
(QV). You can assign specific process variables to the HART variables, and then use standard HART
methods to read or broadcast the assigned process data.
