2.11.3 Simulate device variables
You can temporarily set the pressure, sensor temperature, or scaled variable to a user-
defined fixed value for testing purposes. Once the simulated variable method is left, the
process variable will be automatically returned to a live measurement.
You can only simulate device variables in HART

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 the digital information.
Burst mode applies only to the transmission of dynamic data (pressure and temperature in
engineering units, pressure in percent of range, scaled Vvariable, 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.
Access to information other than dynamic transmitter data is obtained 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.
