Poll address
FastKeys
Enables you to set the poll address for a multi-dropped meter. The poll address is used to
identify each meter on the multi-drop line. Follow the on-screen instructions to set the
address at a number from 1 to 15. To set or change the flowmeter address, establish
communication with the selected Rosemount 8600D in the loop.
Auto poll
FastKeys
When a HART-based communicator is powered up and auto polling is on, the
communicator automatically polls the flowmeter addresses to which it is connected. If the
address is 0, the HART-based communicator enters its normal online mode. If it detects an
address other than 0, the communicator finds each device in the loop and lists them by poll
address and tag. Scroll through the list and select the meter with which you need to
communicate.
If Auto Poll is off, the flowmeter must have the poll address set to 0 or the flowmeter will
not be found. If a single connected device has an address other than zero and auto polling is
off, the device will not be found either.
Number of required preams
FastKeys
The number of preambles required by the 8600D for HART communications.
Number of response preams
FastKeys

Burst mode configuration
The Rosemount 8600D includes a burst mode function that broadcasts the primary

mode is a specialized function used in very specific applications. The burst mode function

burst mode option.
