Modbus card application
The Modbus card allows communication between multiple UPSs and the host system (e.g. SCADA) via the RS-485 bus. Each UPS is equipped with a dedicated Modbus card, which provides a communication interface. Data is sent from the devices to a computer via an RS232/RS485 converter for further processing and analysis in real time.
