OFF-LINE AND ON-LINE OPERATIONS

The HART Communicator can be operated both
off-line and on-line. Off-line operations are those
in which the communicator is not connected to
the IFT system. Off-line operations can include
interfacing the HART Communicator with a PC
(refer to applicable HART Documentation re-
garding HART/PC applications).

In the on-line mode, the communicator is con-
nected to the 4-20 mA analog output signal line.
The communicator is connected in parallel to
the IFT, or in parallel to the 250 ohm load
resistor.

The opening menu (displayed on the LCD) is
different for on-line and off-line operations.
When powering up a disconnected (off-line)
communicator, the LCD will display the Main
Menu. When powering up a connected (on-line)
communicator, the LCD will display the On-line
Menu. Refer to the HART Communicator man-
ual for detailed menu information.
