Chapter 1 Introduction The Eaton® Powerware® Modbus® Card is an X-Slot® connectivity device that allows you to continuously and reliably monitor the UPSs in your Building Management System (BMS). The card uses the Modbus protocol to integrate data from the UPS into your building management software, such as WonderwareR.

Chapter 2 Installing the Modbus Card The Modbus Card is available: S as a separate card for use with UPSs that have an X-Slot S factory-installed in a Powerware Expansion Chassis Use the following sequence for installing the Modbus Card: 1. For four-wire networks only, change the jumpers on the Modbus Card (see “Four-Wire Communication” on page 4). 2.
INSTALLING THE MODBUS CARD Four-Wire Communication The factory-default setting for the Modbus Card is for two-wire communication. To change the default setting, adjust the jumpers on the Modbus Card. CAUTION To prevent electrostatic discharge (ESD), place one hand on an unpainted metal surface such as the UPS rear panel. 1. If you are installing the Modbus Card into an X-Slot, complete Step 3 only. If you are installing the Powerware Expansion Chassis with your UPS, complete Steps 2 through 4. 2.
INSTALLING THE MODBUS CARD 3. Change the J9 and J10 jumpers to the desired setting as shown in Figure 4. Two-Wire (Default) J10 J7 J8 1 J10 1 J9 J9 1 ON S2 1234 56 Four-Wire J10 J11 1 1 J9 Figure 4. Modbus Card Jumpers 4. Reinstall the Modbus Card into the Powerware Expansion Chassis. Align the Modbus Card with the slot guides and slide the card into the slot until it is firmly seated. Secure the Modbus Card with the screws removed in Step 2.
INSTALLING THE MODBUS CARD Installing the Modbus Card into an X-Slot CAUTION To prevent electrostatic discharge (ESD), place one hand on an unpainted metal surface such as the UPS rear panel. 1. Remove the X-Slot cover (or existing X-Slot module) on the UPS rear panel. Retain the screws (see Figure 5). NOTE Some UPSs may have another X-Slot module already installed (such as the Powerware 9125 UPS).
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.
WIRING THE MODBUS CARD Four-Wire Networks The Modbus Card also supports four-wire, half-duplex, RS-485 networks. Figure 7 shows a detailed view of four-wire connections using the Modbus Card terminal strip.

WIRING THE MODBUS CARD For four-wire networks. All four RS-485 network signals including TxD(+), RxD(+), TxD(–), and RxD(–) must be connected to the terminal strip as illustrated in Table 1. Verify that the Modbus Card J9 and J10 jumpers are set to the four-wire option (see “Four-Wire Communication” on page 4). TxD+ RxD+ TxD– RxD– 1 2 3 4 GND 5 Figure 8. RS-485 Terminal Strip Table 1.

WIRING THE MODBUS CARD RS-232 Modbus Port It is also possible to use the RS-232 Modbus port for connecting to your network. 5 4 9 3 8 2 7 1 6 Figure 11. RS-232 DB-9 Pin Numbers Table 3.
Chapter 4 Modbus Card Configuration The Modbus Card has an RS-232 configuration port that you can access with a terminal or a computer equipped with a terminal emulation program. To use the configuration screens for the Modbus Card, you need: S A serial communication cable (supplied). S A terminal with a serial communication port, or a computer with a terminal emulation program such as HyperTerminalR.
MODBUS CARD CONFIGURATION 2. Press [Enter]. The Configuration screen appears (see Figure 13). Powerware Modbus Card Version 1.00 (1-16-02) Current Configuration: Baud Rate: 9600 Slave Address: 29 ----------------------------------------------------------------------------Valid Commands: AD Change Slave Address, usage AD n, where n is the new slave address for the card (1 - 247 valid). BD Change Modbus Baud Rate, usage BD n, where n is the new baud rate (1200, 2400, 4800, 9600, 19200).
MODBUS CARD CONFIGURATION 4. To configure the slave address, type AD followed by a space and node (1 through 247) and press [Enter]. The default is 29. This setting affects both RS-232 and RS-485 Modbus connections. 5. To save and exit, type SA and press [Enter] to permanently save the new configuration changes. 6. The card is now configured. Shut down the terminal emulation program and disconnect the serial cable from the Modbus Card. 7. Continue to Chapter 5, “Integrating the UPS” on page 17.

Chapter 5 Integrating the UPS Powerware provides a software tool named Modbus Profiler that creates a Modbus register map specifically for your Powerware UPS. Refer to the Master Modbus Register Map for a complete list of the Status, Alarm, and Meter data for all Powerware UPS equipment (open the reg_map.pdf file in the directory where the Modbus Profiler tool is located).
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.
