Burst mode is a mode of communication during which the transmitter regularly
broadcasts HART digital information over the mA output. The burst parameters control
the information that is broadcast when burst mode is enabled.

In typical installations, burst mode is disabled. Enable burst mode only if another device on the
network requires burst mode communication.

1.

Enable Burst Mode.

2.

Set Burst Mode Output as desired.

Primary Variable

Source (Primary
Variable)

PV

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

PV current & % of
range

Primary Variable
(Percent Range/
Current)

% range/current

The transmitter sends the PV’s per-
cent of range and the PV’s actual
mA level in each burst (e.g., 25%,
11.0 mA).

Dynamic vars & PV
current

Process Variables/
Current

Process variables/
current

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/sec, 23 °C, 50 g/sec,
0.0023 g/cm3, 11.8 mA).
