3.3.17 Multidrop Mode
3.3.17.1 Setting on HART 5
HART 5
“Multidropping” transmitters refer to the connection
of several transmitters to a single communication
transmission line. Up to 15 transmitters can be
connected 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 is also
disabled.
Setting of Multidrop Mode

(2) Enabling the Multidrop Mode of
CongurationTool
About the procedure to call up the Polling
display, please refer to the User’s Manual of each
conguration tool.
NOTE
When the same polling address is set for
two or more transmitters in multidrop mode,
communication with these transmitters is
disabled.
(3) Communication when set in multidrop
mode.
• The HART conguration tool searches for a
transmitter that is set in multidrop mode when
it is turned on. When the HART conguration
tool is connected to the transmitter, the polling
address and the tag will be displayed.
• Select the desired transmitter. After that, normal
communication to the selected transmitter is
possible. However, the communication speed
will be slow.
To release multidrop mode, call up the Poll addr
display and set the address to “0”.
