The Mitsubishi Electric QJ71MES96N is a highly reliable MES (Manufacturing Execution System) Interface Unit designed specifically for the MELSEC-Q Series programmable logic controllers. This advanced module enables seamless, direct communication between shop floor PLC systems and enterprise-level IT databases without the need for an intermediate gateway PC. By streamlining data collection and production execution, it significantly reduces system complexity and hardware costs. The unit features a standard 10BASE-T/100BASE-TX Ethernet port for robust network connectivity, a CompactFlash (CF) card slot for localized data buffering and storage, and intuitive diagnostic LEDs (RUN/ERR, 100M, SD/RD) for quick status monitoring. Manufactured in Japan to strict industrial standards, it operates efficiently with a power consumption of just 5VDC at 0.50A and carries cULus, CE, and EAC certifications, ensuring safe and compliant operation in global manufacturing environments.
