NOTE
Online communication with the transmitter automatically loads the
current transmitter data to the HART Communicator. Changes in on-
line data are made active by pressing SEND (F2). The transfer function
is used only for off-line data retrieval and sending.
• Frequency Device–The Frequency Device option displays the
frequency output and corresponding pressure output of current-
to-pressure transmitters.
• 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.
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.
Online Menu
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 information 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.
