Quick Start Guide
Note
Rosemount 2051 PROFIBUS PA Profile 3.02 devices are set to identification number
adaptation mode when shipped from the factory. This mode allows the transmitter to
communicate with any PROFIBUS PA control host with either the generic Profile GSD (9700)
or Rosemount 2051 specific GSD (3333) loaded on the host; therefore, it is not required to
change the transmitter identification number at startup.
Assign address
The Rosemount 2051 Pressure Transmitter is shipped with a temporary address
of 126. This must be changed to a unique value between 0 and 125 in order to
establish communication with the host. Usually, addresses 0–2 are reserved for
masters or couplers, therefore transmitter addresses between 3 and 125 are
recommended.
Address can be set via either:
LOI – see

Class 2 master – see Class 2 Master Manual for setting address

Configure engineering units
Unless otherwise requested, the Rosemount 2051 Pressure Transmitter ships
with the following settings:
Measurement mode: Pressure

Engineering units: inches H

Scaling: None

Engineering units should be confirmed or configured before installation. Units
can be configured for Pressure, Flow, or Level measurement.
Measurement type, Units, Scaling, and Low Flow Cutoff (when applicable) can be
set via either:
LOI – see

Class 2 master – see
