Frequency Device–The Frequency Device option displays the frequency output and corresponding pressure output of current-to-pressure transmitters. This is not applicable to the Rosemount 3051N.

Utility–The Utility option provides access to the contrast control for the HART Communicator LCD screen and to the autopoll setting used in multidrop applications. Note that although the Rosemount 3051N has multi-drop capability, which is a HART protocol feature, the Rosemount 3051N is not qualified/dedicated for use in multi-drop mode.

Once selecting a MAIN menu option, the HART Communicator provides the information you need to complete the operation. If further details are required, consult the HART Communicator manual.

The ONLINE MENU can be selected from the MAIN menu as outlined above, or it may appear automatically if the HART Communicator is connected to an active loop and can detect an operating transmitter.

NOTE

The MAIN menu can be accessed from the ONLINE MENU. Press the left arrow action key to deactivate the on-line communication with the transmitter and to activate the MAIN menu options.

When configuration variables are reset in the on-line mode, the new settings are not activated until the data is sent to the transmitter. Press SEND (F2) when it is activated to update the process variables of the transmitter.

On-line mode is used for direct evaluation of a particular meter, re-configuration, changing parameters, maintenance, and other functions.
