J-6 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 re-

sistor.

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.
