Rosemount Model 3144 and 3244MV Smart Temperature Transmitters

Figure 3-3. Typical Multidropped
Network.
Figure 3-3 shows a typical multidrop network. Do not use this figure as
an installation diagram. Contact Rosemount product support with
specific requirements for multidrop applications.
A HART communicator can test, configure, and format a multidropped
transmitter in the same way as in a standard point-to-point
installation.
NOTE
The Model 3144 and 3244MV transmitters are set to address 0 at the
factory, allowing them to operate in the standard point-to-point manner
with a 4–20 mA output signal. To activate multidrop communication,
the transmitter address must be changed to a number between 1 and
15. This change deactivates the 4–20 mA analog output, sending it to
4 mA. The failure mode current also is disabled.
