The 3051S is set to address zero (0) at the factory, which allows operation 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 from 1 to 15. This change deactivates the 4–20 mA analog output,
sending it to 4 mA. It also disables the failure mode alarm signal, which is
controlled by the upscale/downscale switch/jumper position. Failure signals in
multidropped transmitters are communicated through HART messages.
To activate multidrop communication, the transmitter poll address must be
assigned a number from 1 to 15, and each transmitter in a multidropped loop
must have a unique poll address.
