Burst Mode Configuration
The Rosemount 8800D includes a burst mode function that broadcasts the
primary variable or all dynamic variables approximately three to four times a
second. The burst mode is a specialized function used in very specific
applications. The burst mode function enables you to select the variables to
broadcast while in the burst mode and to select the burst mode option.
The Burst Mode variable enables you to set the Burst Mode to the needs of
your application. Options for the Burst Mode setting include:
Off–Turns off the Burst Mode so that no data are broadcast on the loop.
On–Turns Burst Mode on so that the data selected under Burst Option are
broadcast over the loop.
Additional command options may appear that are reserved and do not apply
to the Rosemount 8800D.
