Introduction
The GW BMS SS is designed for applications where Modbus RTU slave devices need to communicate with other slave devices. It allows slave-to-slave data sharing by acting as an intelligent intermediary, enabling seamless communication between serial and Ethernet Modbus networks. Both gateways support CSV-based configuration and flexible RS-485 port roles, but they are differentiated by the type of Modbus device.
