Mitsubishi QJ71WS96-C Web Server Module for MELSEC-Q Series

The Mitsubishi QJ71WS96-C (QJ71WS96-C) is a dedicated web server module designed for use within Mitsubishi MELSEC-Q series programmable logic controller architectures. Serving as an intelligent communication interface, this unit enables Ethernet-based connectivity, web-based monitoring, and remote data exchange for automated control systems. It mounts directly onto compatible MELSEC-Q series base units, allowing system integrators and maintenance personnel to access internal PLC registers, monitor machine operating status, and manage diagnostics through standard network protocols and web browser interfaces without requiring specialized client software. In industrial automation installations, the QJ71WS96-C facilitates integration between shop-floor control hardware and supervisory network environments. It supports critical automation tasks across manufacturing lines, packaging machinery, material handling equipment, and process control facilities that depend on the MELSEC-Q platform. With a specified weight of 10 kg, this genuine replacement module provides an exact form, fit, and operational match for existing automation racks. Incorporating the module into routine maintenance planning or legacy upgrades helps restore communication capabilities, prevent unpredicted production interruptions, and extend the operating life of established Mitsubishi control infrastructure.
