OFF-LINE AND ON-LINE
OPERATIONS
The Field Communicator can be operated both off-line and on-line.
Off-line operations are those in which the communicator is not connected to
the OCX 8800. Off-line operations can include interfacing the Field Communi-
cator with a PC (refer to applicable Field Communicator documentation
regarding Model 375/PC applications). In the on-line mode the communicator
is connected to a fieldbus terminal block.
NOTE
If the Field Communicator is turned on while connected to the fieldbus
terminal block, an undefined status indication appears while the
communicator warms up. Wait until the warm-up period ends to continue.
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 Field
Communicator manual for detailed menu information.
