STEP 5: BASIC CONFIGURATION
Configuration Tasks
The transmitter can be configured via either the Local Operator Interface (LOI) – option
code M4, or via a Class 2 master (DD or DTM based). The two basic configuration tasks for
the PROFIBUS PA Pressure transmitter are:
1. Assign Address.
2. Configure Engineering Units (scaling).
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 Table 1 and Figure 8
• 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
2
O
• 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 Table 1 and Figure 8
• Class 2 master – see Table 2 for parameter configuration
Configuration Tools
Local Operator Interface (LOI)
When ordered, the LOI can be used for commissioning the device. To activate the LOI,
push either configuration button located under the top tag of the transmitter. See Table 1
and Figure 8 for operation and menu information.
NOTE
Buttons must be fully engaged ≈ 0.5 in. (10 mm) of travel.
