Working Principle Module exchanges data with RX3i CPU through backplane bus. Dual Ethernet ports complete physical layer signal transceiving, realize protocol encapsulation and parsing. Achieve data interaction between local PLC system and remote HMI, SCADA or other network devices. LED reflects real‑time link and communication activity status.
Installation Requirements Insert module into idle slot of RX3i main or expansion rack. Complete cabinet protective grounding. Configure IP address through programming software. Use shielded twisted‑pair Ethernet cables. Power‑off rack before module replacement, hot‑swap forbidden. Separate network cables from high‑voltage power cables.
Usage Notes Reasonably plan IP address to avoid network conflict. Observe link LED for network fault troubleshooting. Do not connect untrusted public network directly. Forbid on‑site disassembly. Avoid corrosive gas, liquid splash and oil mist.
