The LW-EC series is a self-developed high-performance Modbus RTU to EtherCAT gateway with high-speed transmission and multi-independent RS485 channels. It is available in 3-channel, 6-channel and 12-channel models. The gateway seamlessly converts Modbus RTU to EtherCAT protocol, allowing Modbus RTU devices such as meters, inverters, protection relays and soft starters to connect to EtherCAT-based controllers from Beckhoff, Omron, Keyence, Delta, Inovance and Xinje. Operating as an EtherCAT slave, the gateway provides RS485 serial interfaces and integrates a Modbus RTU master function for reliable serial-to-EtherCAT data conversion.
