A-9
HART Communicator
Online Menu
The Online Menu can be selected from the Main Menu or it appears
automatically if the HART Communicator is connected to an active
loop and can detect an operating Level Controller.
Online mode is used for direct evaluation of a particular meter, re-
configuration, changing parameters, maintenance, and other functions.
When configuration variables are reset in online mode, the new
settings are not activated until the data is sent to the gauge. Press
SEND (F2) when it is activated to update the process variables of the
Level Controller.
NOTE
The Main Menu can be accessed from the Online Menu. Press the left
arrow action key to deactivate the online communication with the Level
Controller and to activate the Main Menu options.
HART Fast Key Feature
The HART Fast Key feature provides quick online access to Level
Controller variables and functions. Instead of stepping your way
through the menu structure using the Action Keys, you can press a
HART Fast Key sequence to move from the Online Menu to the desired
variable or function. On-screen instructions guide you through the rest
of the screens.
The HART Fast Key sequences are made up of the series of numbers
corresponding to the individual options in each step of the menu
structure. For example, from the Online Menu you can change the
Date. Following the menu structure, you would:
1. Press 6 to reach Device Setup.
2. Press 4 for General Setup.
3. Press 3 for Device Information.
4. Press 5 for Date.
So, the corresponding HART Fast Key sequence is 6, 4, 3, 5.
HART Fast Keys are operational only from the Online Menu. If you use
them consistently, you return to the Online Menu by pressing HOME
(F3) when it is available. If you do not start at the Online Menu, the
HART Fast Keys will not function properly.
Use Table A-1, an alphabetical listing of online functions, to find the
corresponding HART Fast Keys. These codes are applicable only to the
Level Controller and the HART Communicator.
