It includes an integrated 3‑port switch with two external RJ45 ports, enabling line or star topologies and simplifying wiring. The coupler auto‑detects 10\/100 Mbit\/s speeds, maps up to 64 terminals (255 with K‑bus extension), and supports a large process image of 492 bytes input and 492 bytes output.\u003c\/p\u003e\n\n  \u003ch3\u003eKey Features\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eEtherNet\/IP™ (CIP over TCP\/UDP\/IP);
