HART
Set the Transmitter to Burst Mode
To set the transmitter to burst mode, follow the steps below with the
Traditional Fast Key sequence:
1. From the Home screen, select 1 Device setup, 3 Configuration, 4 Device
output configuration, 3 HART output, 4 Burst option to begin setting the
transmitter to burst command 3. The communicator displays the Burst
option screen.
2. Select Process vars/current. The communicator returns to the HART
output screen.
3. Select 3Burst mode to prepare to enable Burst Mode. The
communicator displays the Burst Mode screen.
4. Select On to enable Burst Mode. The communicator returns to the HART
output screen.
5. Select Send to download the new configuration information to the
transmitter.
Set Process Variable Output Order
To set the process variable output order, follow the steps below with the
Traditional Fast Key sequence:
1. From the Home screen, select 1 Device setup, 3 Configuration,
1 Variable Mapping, 5 Variable Remapping. Select OK to set the control
loop to manual. The communicator displays the Primary Variable screen.
2. Select the item to be set as the primary variable at the Select PV prompt.
3. Repeat step 2 for the SV, TV, and QV. The communicator displays the
Variable mapping screen.
4. Select OK to accept the order to which the variables are mapped, or
Abort to abort the entire procedure.
NOTE
Take careful note of the process variable output order. The HART Tri-Loop
must be configured to read the variables in the same order.
5. Select OK to return the control loop to automatic control.
Special Considerations
To initiate operation between a 3144P transmitter with dual-sensor option and
the HART Tri-Loop, consider the configuration of both the differential,
average, first good temperatures, Sensor Drift Alert, and Hot Backup features
(if applicable).
Differential Temperature Measurement
To enable the differential temperature measurement feature of a
dual-sensor 3144P operating in conjunction with the HART Tri-Loop,
adjust the range end points of the corresponding channel on the HART
Tri-Loop to include zero. For example, if the secondary variable is to report
the differential temperature, configure the transmitter accordingly (see “Set
Process Variable Output Order” on page 3-27) and adjust the
corresponding channel of the HART Tri-Loop so one range end point is
negative and the other is positive.
