II. Product Working Principle and Overview

RLX2-IFH24E-E is an industrial automation dedicated wireless transparent Ethernet bridge, mainly solving the problem of **PLC/DCS remote Ethernet communication in scenarios where wired wiring cannot be laid**:

1. **Networking Mode**: Configurable as a master station, relay repeater, or remote slave station, supports **point-to-point (PTP), point-to-multipoint (PTMP), multi-level relay chain networking**; built-in Smart Switch intelligent virtual point-to-point switching to avoid broadcast storms 2. **Data Transmission**: Each end is equipped with a corresponding wireless radio. The Ethernet data packets are transparently forwarded through the FHSS frequency-hopping wireless link. The upper-level PLC does not need to modify the program. Industrial protocols such as EtherNet/IP and Modbus TCP operate seamlessly without any impact.
