Mitsubishi Electric QJ71GF11-T2 CC-Link IE Field Master Module

Description

Integrating seamlessly into high-speed industrial networks, the QJ71GF11-T2 serves as a high-performance communication interface within the MELSEC-Q automation platform. This module enables deterministic, high-capacity data exchange by functioning as either a master or local station on a CC-Link IE Field network. Operating at a transmission speed of 1 Gbps, it manages extensive digital and analog I/O points across distributed automation architectures, ensuring synchronized control and rapid diagnostic capabilities.

The unit supports versatile physical layouts including line, star, and ring network topologies, which can be combined to suit complex factory floor environments. Its integration within the MELSEC-Q series allows for straightforward configuration via GX Works software, reducing engineering overhead and optimizing data throughput for heavy industrial processing.

Features

• High-Speed Communication: Operates at a physical layer speed of 1 Gbps for rapid data transmission.
• Flexible Topologies: Supports line, star, and ring network configurations, including hybrid line/star systems.
• Dual-Role Capability: Configurable as either a network Master Station or a Local Station.
• Token Passing Method: Implements a deterministic token-passing communication scheme to prevent network collisions.
• Massive Data Capacity: Handles up to 16,384 RX/RY points and 8,192 RWr/RWw words per network.
• Extended Distances: Supports up to 100 meters between stations and up to 12,100 meters total loop distance in ring configurations.

Applications

• Automotive assembly and robotic welding lines
• High-speed packaging and sorting machinery
• Water and wastewater treatment distribution systems
• Material handling and automated warehousing systems
• Distributed PLC-to-PLC communication links in processing plants

Installation Guidelines

• Mounting: Place the module into the standard slot of a MELSEC-Q series main or extension base unit. Secure the unit with the module fixing screw to prevent vibration-induced disconnections.
• Cabling Requirements: Use only double-shielded, Category 5e or higher STP straight cables. Standard unshielded twisted pair (UTP) cables should not be used due to noise sensitivity at 1 Gbps speeds.
• Noise Abatement: Route communication cables away from high-voltage cables and motor drive lines by a minimum of 100 mm to avoid electromagnetic interference.
• Grounding: Ensure the base unit's functional ground (FG) terminal is connected to a dedicated class D ground (grounding resistance of 100 ohms or less).
