(3) Enabling multidrop communication on the
configuration tool side
Refer to the configuration tool manual, and
configure the receiver side polling settings.
(4) Communication in multidrop mode
1. When the power is turned on, the HART
configuration tool searches for devices set to
multidrop mode.
If the HART configuration tool is connected to
devices, their polling addresses and tags are
displayed.
2. Selecting the device of your choice enables
communication with the selected device.
However, communication in this mode will be
slow.
(5) Clearing multidrop mode
To clear multidrop mode, display the Poll addr
parameter by following the procedure in step (1),
“Setting the polling address,” and set the address
to 0.
And, set Loop current mode back to Enabled.
