Mitsubishi Electric LJ72GF15-T2 MELSEC L Series CC-Link IE Field Network Head Module

Description

Facilitating high-speed deterministic communication within distributed control architectures, the Mitsubishi Electric LJ72GF15-T2 serves as a rugged interface node linking remote MELSEC L Series I/O and intelligent function modules to a CC-Link IE Field Network. This head module translates high-speed network frames into local backplane transactions, allowing seamlessly distributed physical arrangements without sacrificing I/O response speeds. Designed with dual RJ45 ports, it accommodates robust redundant and ring topologies to maximize system uptime in continuous-process industrial environments.

Key Features

• Gigabit Ethernet physical layer delivering deterministic 1 Gbps transmission speed.
• Flexible network topology support including line, star, mixed, and high-availability ring structures.
• Accommodates up to 10 local MELSEC L Series extension modules per head node.
• Integrated RAS diagnostic tools including event logging, system test modes, and error tracking.
• Dual communication ports allowing simple daisy-chaining without external switches.

Applications

• Distributed conveyor control systems and logistics hubs.
• Multi-station automotive assembly and welding cells.
• Water treatment plants with physically isolated pumping stations.
• Packaging and bottling machines requiring high-density remote I/O layout.

Alternative Models & Compatibility

The LJ72GF15-T2 is specifically designed for the MELSEC L Series modular platform. Ensure your engineering environment is updated with GX Works2 to allow seamless network profile registration of this specific head module station.

Application Pitfalls & Engineering Notes

This module relies on passive ventilation. In high-density electrical cabinets with ambient temperatures trending toward the upper limit, ensure at least 80mm of vertical clearances above and below the module assembly to prevent localized overheating and subsequent fieldbus dropouts.

Commissioning & Wiring Tips

For reliable 1 Gbps performance, standard unshielded patch cords are strictly prohibited. You must use double-shielded industrial-grade Category 5e (STP) cables. Ensure the metal shield of the RJ45 jack is properly grounded to the DIN rail ground assembly via the head module's functional ground connection.
