Chapter 3 Wiring the Modbus Card
The Modbus Card provides an easy path for integrating a Powerware
UPS into an RS-485 Modbus network and also provides isolation of the
communication between the UPS and the RS-485 Modbus network.
You can use the DB-9 port or terminal strip on the Modbus Card to wire
into a two-wire or four-wire network.
Two-Wire Networks
The Modbus Card’s default configuration is for two-wire, half-duplex,
RS-485 networks. Figure 6 shows a detailed view of two-wire
connections using the Modbus Card terminal strip.

RS-485 Terminal Strip
The RS-485 five-position terminal strip provides an alternate interface to
attach the RS-485 transmission lines. This connector also allows external
resistors to be applied to terminate the network.
Before connecting the RS-485 network to the Modbus Card, remove the
detachable plug from the 5-pin terminal strip connector. The RS-485
signal names are shown just above the connector (see Figure 8).
For two-wire networks. Connect the RS-485 network signal TxD(+) to the
RxD(+) input signal on the Modbus Card terminal strip. Connect the
RS-485 network signal TxD(–) to the RxD(–) input signal on the Modbus

CAUTION
Termination resistors should be placed only at the extreme ends of the RS-485 network. No
more than two termination points should be used in the RS-485 network.
Termination is not required unless the Modbus Card is located at the
end of the RS-485 network or the length of the network cable is
excessive.
If receive termination is required, an on-board 120 ohm termination
resistor may be selected by setting S2-3 to the ON position. A 120 ohm
resistor will be placed in parallel with the RxD(+) and RxD(–) lines (see
Figure 10).
If transmit termination (four-wire networks) is required, an on-board
120 ohm termination resistor may be selected by setting S2-4 to the ON
position. A 120 ohm resistor will be placed in parallel with the TxD(+)
and TxD(–) lines (see Figure 10).

Figure 10. S2 Termination Configuration
If a value other than the on-board 120 ohm termination is required, then
S2-3 and S2-4 should be set to the OFF position. The Modbus Card
terminal strip provides easy access to attach external termination
resistors across the TxD(+), TxD(–), RxD(+), and RxD(–) RS-485 network
lines.
Biasing Resistors
CAUTION
Biasing resistors should be used at only one point in the RS-485 network.
Biasing resistors are used to ensure that the idle voltage sensed across
the receiver does not create false data bits. The factory-default for
S2 (1–6) is OFF.
Two on-board 620 ohm biasing resistors may be selected by setting
S2-1 and S2-2 to the ON position. If biasing is set at the master terminal
unit, then S2-1, S2-2, S2-5, and S2-6 should be set to the OFF position.

INTEGRATING THE UPS
5. Run profiler from the command prompt or double-click profiler.exe
from Microsoft Windows Explorer.
By default, Modbus Profiler uses the communication port specified
in the [Connection] section of the profiler.ini file. If profiler fails to
connect using this communication port, you are prompted with a
list of alternate communication ports. You may also edit the Port=
value in the [Connection] section of the profiler.ini file to change the
default value.
6. Modbus Profiler creates an output file named profiler.csv in the
directory where the Modbus Profiler tool is located.
Before the program exits, you are prompted to view the data.
The comma delimited file can be easily imported into Microsoft
Excel for viewing of the Modbus data. This data is used to create
the necessary template files on your Building Management System
for polling the desired UPS information.
NOTE Modbus Profiler does not provide Modbus data for the Powerware 9315 Series UPS.
Powerware 9315 configuration-specific profiles are available in the directory where the

For four-wire networks. Verify that all four
RS-485 network signals are connected to the
terminal strip or DB-9 connector as illustrated
in Table 1 on page 9 or Table 2 on page 10,
respectively.
See Chapter 3, “Wiring the Modbus Card” on
page 7 for more information.
If the Modbus Card is the last device installed
in the network chain or the length of the
network cable is excessive, termination
needs to be enabled.
J9 and J10 jumpers could be in the incorrect
position for your configuration.
The polling rate in the Building Management
Software (BMS) application or Modbus
software is set below 500 mS.
Verify the termination settings (see
“Termination” on page 10 for the correct
settings).
Verify the jumpers are in the correct position
(see Figure 4 on page 5).
The Modbus Card updates the status of the
Eaton equipment every 1000 mS. Configure
the BMS/Modbus application polling rate to
500 mS or greater to ensure proper operation.
