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 start-up.
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
• 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
• Scaling: None
