8. OPERATION VIA HART COMMUNICATOR
(2) Activating the multidrop mode
About the procedure to call up the Polling display,
please refer to the User’s Manual of each configu-
ration tool.
NOTE
When the same polling address is assigned for
two or more field devices in multidrop mode,
communication with these field devices is
disabled.
(3) Communication when set in the multidrop mode
1. The HART configuration tool searches a field
device that is set in the multidrop mode when
the HART configuration tool is turned on.
When the HART configuration tool is connected
to the field device, the polling address and the
tag will be displayed.
2. Select the field device, and then communication
with it is possible. The communication speed is
slow in this case.
3. To communicate with another field device, turn
off the power once and then turn it back on, or
call up “Online” menu, and select “Online.”
The polling address and the tag will appear.
Select the field device.
(4) Release of the multidrop mode
Call up the “Poll addr” display, and set the
address to “0.”
