Configuration
To configure the PV, SV, TV, and QV assignments:
•
Using the Communicator:
-
To configure the PV, assign the desired process variable to the mA output. See
Section 6.2.1

.
•
Using ProLink II, click
ProLink > Configuration > Variable Mapping
.

Burst mode
Burst mode is a specialized mode of communication during which the transmitter regularly broadcasts
HART digital information over the mA output. Burst mode is ordinarily disabled, and should be
enabled only if another device on the network requires burst mode communication.
HART digital information over the mA output. Burst mode is ordinarily disabled, and should be
enabled only if another device on the network requires burst mode communication.
Note: If burst mode is enabled, HART/Bell 202 communications via a HART modem (as required by
ProLink II) may be very slow, or the HART connection may fail completely. If either of these occurs,
disable burst mode, use a communications tool that does not require a HART modem (i.e., the
Communicator), try a HART modem from a different vendor, or try a USB HART modem. Ensure that
RTS line control is managed by the modem.

1. Navigate to the correct menu:
•
If you are using the Communicator, select
Detailed Setup > Config Outputs >
HART Output
.
•
If you are using ProLink II, click
ProLink > Configuration > Device
.
Note: You cannot configure burst mode with the display.
2. Enable burst mode.
3. Specify the Burst Mode Output. Options are described in Table 6-7.
4. If you specified
Transmitter vars
or
Fld dev var
in Step 3, specify the four process variables
to be sent in each burst.
