2.11.3 Simulate device variables
It is possible to 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. Simulate device
variables is only available in HART
Simulate digital signal with a Field Communicator
From the HOME screen, enter the Fast Key sequence.
Device Dashboard Fast Keys
Simulate digital signal with AMS Device Manager
Procedure
1. Right select on the device and select Service Tools.
2. Select Simulate.
3. Under Device Variables select a digital value to simulate.
4. Follow the screen prompts to simulate selected digital value.

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 Variable, and/or analog output),
and does not affect the way other transmitter data is accessed. However, when activated,
bust 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.
