Basic configuration
5.1 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:
Procedure
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.
5.1.1 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
and
•
Class 2 master – see Class 2 Master Manual for setting address
5.1.2 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:
