7-3 HART COMMUNICATOR PC
CONNECTIONS
There is an option to interface the HART Com-
municator with a personal computer. Load the
designated AMS software into the PC. Then link
the HART Communicator to the PC using the
interface PC adapter that connects to the serial
port (on the communicator rear panel). Refer to
the proper HART Communicator documentation
in regard to the PC interface option.
7-4 OFF-LINE AND ON-LINE OPERATIONS
The HART Communicator can be operated both
off-line and on-line.
a. Off-line operations are those in which the
communicator is not connected to the Oxy-
mitter 4000. Off-line operations can include
interfacing the HART Communicator with a
PC (refer to applicable HART documentation
regarding HART/PC applications.
b. In the on-line mode, the communicator is
connected to the 4-20 mA analog output sig-
nal line. The communicator is connected in
parallel to the Oxymitter 4000 or in parallel to
the 250 ohm load resistor.
NOTE
If the HART Communicator is turned
on while connected to the 4-20 mA
analog output signal line, an undefined
status indication appears while the
communicator warms up. Wait until the
warmup period ends to continue.
c. 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 Communi-
cator manual for detailed menu information.
7-5 LOGIC I/O CONFIGURATIONS
The Oxymitter 4000 logic I/O output can be
configured for ten different modes through
HART/AMS. The factory default condition is
Mode 5. A list of possible configurations appear
in Table 7-1. The Unit Alarm configuration avail-
able for Modes 1, 3, 5, and 7 refers to the diag-
nostic alarm faults in Table 8-1 and Table 8-2.
7-6 MENU TREE FOR HART COMMUNICA-
TOR/OXYMITTER 4000 APPLICATIONS
This section consists of a menu tree for the
HART Communicator. This menu is specific to
Oxymitter 4000 applications.
