Introduction

The MODBUSCARD provides a compatible SmartOnline® UPS system communication functionality with a PC by way of the MODBUS protocol.

Features

• Implements MODBUS protocol

• Provides MODBUS functions, including Read Coils, Discrete Inputs, Holding Registers, Input Registers, Write Single Coils and Write Single Registers

• Provides communication through RS-232, RS-485 or RS-422 interfaces

• Simultaneous communication through RS-232 and RS-485, or RS-232 and RS-422 connection interfaces

RS-422

For RS-232 connection, use terminals 6 (Tx), 7 (Rx), 8 (G).

For RS-485, use terminals 1 (T+), 2 (T-), 5 (G) for half-duplex communication.

For RS-422, use terminals 1 (T+), 2 (T-), 3 (R+), 4 (R-), 5 (G) for full-duplex communication.

Note: The communication methods chosen must have its conﬁguration dip switches set prior to installing the MODBUSCARD into the UPS systems accessory slot.

Device ID Conﬁguration

Every MODBUS device needs to be set to a speciﬁc ID in order to be recognized by the system monitoring its MODBUS communication. Each switch of SW1 has a speciﬁc value assigned to it. The MODBUSCARD supports device IDs from 0-255, starting from the Least Signiﬁcant Bit (LSB) to the Most Signiﬁcant Bit (MSB). See Device ID Switch Values (Figure A).

Installation

The MODBUSCARD should be installed in the accessory slot of a compatible SmartOnline UPS system.

Note: Prior to installing the card into the UPS, all conﬁguration switches should be set to the values required by the UPS and your PC communication ports.

1. Remove the screws securing the blank cover plate from the UPS and set them aside.

2. Detach the communication terminal connector from the MODBUSCARD.

3. Slide the conﬁgured MODBUSCARD into the UPS accessory slot

4. With the screws that were removed in step 1, attach the compatible cover plate that came with MODBUSCARD to the accessory slot mounting points.

5. Re-insert the wired terminal strip connector into the MODBUSCARD port.

6. The MODBUSCARD’s red LED will ﬂash to indicate the UPS is connected and ready for communication.

7. The user will need to supply the means of communication on the PC side via RS-232, RS-422, or RS-485, as well as the appropriate monitoring software.
