Configuration
The Rosemount 2088 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 for HART
Revision 5, or 1-63 for HART Revision 7. 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 position. Failure signals in multidropped transmitters are
communicated through HART messages.
2.11.1 Changing a transmitter address
To activate multidrop communication, the transmitter poll address must be assigned a number
from 1 to 15 for HART Revision 5, and 1-63 for HART Revision 7. Each transmitter in a
multidropped loop must have a unique poll address.
