2. HART COMMUNICATOR OPERATION
(15) Burst Mode
The transmitter continuously sends the data stored in it
when the burst mode is set on. Either one of measured
pressure variable, % output value, or 4 to 20 mA
output value can be selected and sent. The data is sent
intermittently as a digital signal at 75 ms intervals
when the transmitter is set in the burst mode. There-
fore, communication by the HART simultaneous
communicator is also possible.
Setting of Burst Mode
F0234.EPS
Call up the Burst option, and set
the data to be sent.
• Pressure variable (PV)
• % output value (% range/current)
• 4 to 20 mA output value (Process
vars/crnt)

(16) Multidrop Mode
“Multidropping”
transmitters refers to the connection
of several transmitters to a single communications
transmission line. Up to 15 transmitters can be con-
nected when set in the multidrop mode. To activate
multidrop communication, the transmitter address must
be changed to a number from 1 to 15. This change
deactivates the 4 to 20 mA analog output, sending it to
4 mA. The alarm current also is disabled.
Setting of Multidrop Mode
F0235.EPS
Call up the Poll addr and set the
polling address. (a number from 1 to
15)

NOTE
1. When the address is set and the multi-drop
mode is set to “No” at the same time, Online
menus cannot be called up and displayed. Be
sure to turn the multidrop mode to “Yes” after
setting the address with “Poll addr.”
2. When the same polling address is set for two
or more transmitters in multidrop mode,
communication with these transmitters is
disabled.
