Product Description

Description

Facilitating seamless industrial network communications, the QJ71E71-100 serves as a high-performance Ethernet interface module for the Mitsubishi Electric MELSEC-Q Series PLC platform. This module enables direct, reliable connections between Q-Series programmable controllers and host systems, supervisory personal computers, or other Ethernet-enabled automation devices. Operating at speeds up to 100 Mbps, it supports simultaneous open connections and robust, secure data transmission across complex manufacturing cells and plant-wide industrial networks. By offloading processing overhead from the main CPU, it ensures optimized system-level performance.

Features

  • Dual-rate transmission support accommodating 10BASE-T and 100BASE-TX interfaces.
  • Supports up to 16 simultaneously open connections for parallel host and peer-to-peer communications.
  • Compact single-slot footprint designed for seamless integration within standard MELSEC-Q backplanes.
  • Direct configuration and parametric setup utilizing standard GX Works2 or GX Developer programming software.
  • Front-panel diagnostic LEDs providing immediate physical feedback on link, run, and communication error status.

Applications

  • Industrial supervisory control and data acquisition (SCADA) network integration.
  • High-speed peer-to-peer inter-PLC data exchange.
  • Centralized database connectivity and remote machine telemetry monitoring.
  • Manufacturing execution systems (MES) and enterprise resource planning (ERP) system integration.
