Choosing a burst option
This parameter selects the information to be burst. Make a selection from the Burst Option drop-down
menu under the Burst Mode heading. The Dyn vars/current option is the most common, because it is used
to communicate with the Rosemount 333 HART Tri-Loop
™
.
Choosing burst variable slot definition
If the burst option Device vars w/ status or Device variables is selected, the user may select the four
variables that will be burst. These are defined in slots 1–4 under the Burst Variable Slot Definitions
heading. The variables defined in slots 1–4 can be different than the variables mapped to the primary,
2nd, 3rd, and 4th variable outputs.
Multidrop communication
Multidropping transmitters refers to the connection of several transmitters to a single communications
transmission line.
Note
Figure 2-24 on page 35 shows a typical multidrop network. This figure is not intended as an installation
diagram.
Communication between the host and the transmitters takes place digitally with the analog output of
the transmitters deactivated.
Note
A transmitter in multidrop mode with Loop Current Mode disabled has the analog output fixed at 4 mA.
