9.2.3 Burst Lists
Burst mode is a special mode of a HART slave device which allows it to periodically send the
response to a selected HART command without the being polled by the master. For a Wire-
lessHART slave device, it is the main operating mode. and can be used, for instance, to send
the process values from an adapter or connected HART device to Fieldgate SWG70 at regular
intervals.
The burst lists, contain information on the devices operating in this mode. The measured
values sent by the devices can be viewed in the Measurement List. See Chapter 11 "Addi-
tional Functions" on page 102.
