Model 268
SMART FAMILY Interface

OVERVIEW

The Rosemount Model 268 SMART FAMILY Interface provides a
common communications link to the Rosemount family of
microprocessor-based instruments. The Model 268 communicates with
any of the Rosemount smart instruments from any wiring termination
point in the loop, provided there is between 250 and 1100 ohms
resistance between the connection and the power supply.

This section introduces the Model 268 display, keypad, menu structure
and Function Key Sequences for the transmitter and Model 268.

The Model 268 Revisions 5.0 through 6.2 can communicate with the
Model 3144 and 3244MV with limited functionality. The transmitter
information is read-only except for reranging the 4–20 mA signal.

The Model 268 revision 7.0 communicates with the Model 3144 and
3244MV and has the ability to perform such tasks as changing sensor
type and number of wires. However, dual sensor and sensor matching
features are not available using any revision of the Model 268. The
Model 275 HART Communicator is the necessary interface for complete
functionality, and is recommended.

Contact a Rosemount Service Center to upgrade the revision level of a
Model 268.

SAFETY MESSAGES

Instructions and procedures in this section may require special
precautions to ensure the safety of the personnel performing the
operations. Information that potentially raises safety issues is indicated
by a warning symbol ( ). Please refer to the following safety messages
before performing an operation preceded by this symbol.

Warnings

Explosions could result in death or serious injury.

•

Before connecting the communicator in an explosive atmosphere, make sure
the instruments in the loop are installed in accordance with intrinsically safe or
nonincendive field wiring practices.
