Configuring burst mode

Burst mode is compatible with the analog signal. Because the HART
simultaneous digital and analog data transmission, the analog value can drive other
equipment in the loop while the control system is receiving digital information.
Burst mode applies only to to the transmission of dynamic data (pressure and temperature
in engineering units, pressure in percent of range, scaled variable, and/or analog output)
and does not affect the way other transmitter data is accessed. However, when activated,
burst mode can slow down communication of non-dynamic data to the host by 50
percent.
The transmitter accesses information other than dynamic transmitter data through the
normal poll/response method of HART Communication. A Field Communicator, AMS
Device Manager, or the control system may request any of the information that is
normally available while the transmitter is in burst mode. Between each message sent by
the transmitter, a short pause allows the Field Communicator, AMS Device Manager, or a
control system to initiate a request.
