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.

Installation Guidelines

CRITICAL WARNING:

Isolate and lock out all external power supplies connected to the master PLC and the remote node prior to physical hardware mounting, module joining, or communication cable termination. Failure to de-energize can damage sensitive internal backplane components.

1 Mount the LJ72GF15-T2 module firmly onto a standardized 35mm symmetrical DIN rail.
2 Slide and lock local L Series I/O or intelligent modules to the right of the head module, ensuring proper backplane connector engagement.
3 Connect double-shielded STP cables into PORT 1 and PORT 2 based on your physical topology design.
4 Affix the modular end-plate to the last physical module on the rail to protect internal signals.

FAQ

What is the maximum number of extension modules supported by the LJ72GF15-T2?

The module supports a maximum of 10 local MELSEC L Series I/O or intelligent function modules connected directly to its backplane.

What kind of cabling is required to run the network at its full 1 Gbps capacity?

You must use double-shielded Category 5e (or higher) Ethernet cables compliant with 1000BASE-T specifications to maintain deterministic performance.

Which software is used to configure the network settings for this head module?

Network configuration, module parameter setting, and diagnostics are performed using GX Works2 software.

Does the head module support redundant loop configurations?

Yes, its dual-port design natively supports ring topologies, ensuring continuous network operation even if a segment breaks.
