HART Tri-Loop HART-to-Analog Signal Converter

Fast Key Sequences HART fast key sequences provide quick on-line access to transmitter
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.
Fast Key Sequence Conventions The fast key sequences for the Model 275 use the following conventions
for their identification:
1 through 9 –Refer to the keys located directly below the dedicated
keypad.
Left Arrow –Refers to the left arrow directional key.
Fast Key Sequence Example 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
Poll
Addr . Following the menu structure, press 1 to reach Device Setup ,
press 3 for Detailed Setup , press 1 for Output Condition , press 2 for
HART Output, and 1 for Poll Addr . The corresponding HART fast
key sequence is 1, 3, 1, 2, 1.
HART fast keys are operational only from the Online Menu. If you use
them consistently, you will need to return to the Online Menu by
pressing
(F3) when it is available. If you do not start at the Online
Menu, the HART fast key sequences will not function properly.
Use Table B-1, an alphabetical listing of every on-line function, to find
the corresponding HART fast key sequences. These codes are applicable
only to Level Controller and the HART Communicator.
MENUS AND FUNCTIONS The HART Communicator is a menu driven system. Each screen
provides a menu of options that can be selected as outlined above, or
provides direction for input of data, warnings, messages, or other
instructions.
Main Menu When the HART Communicator is turned on, one of two menus will
appear. If the HART Communicator is connected to an operating loop,
the communicator will find the device and display the Online Menu (see
below). If it is not connected to a loop, the communicator will indicate
that no device was found. When you press OK (F4), it will display the
Main menu.
The Main menu provides the following options:
• Offline –The Offline option provides access to offline configuration
data and simulation functions.
• Online –The Online option checks for a device and if it finds one,
brings up the Online Menu.
• Transfer –The Transfer option provides access to options for
transferring data either from the HART Communicator (memory)
to the transmitter (device) or vice versa. Transfer is used to move
off-line data from the HART Communicator to the transmitter, or
to retrieve data from a transmitter for off-line revision.
