GX Works3 Reviews, Pricing, Features & Alternatives in 2026
GX Works3 is a comprehensive configuration and programming software designed to simplify the setup, maintenance, and operation of Mitsubishi Electric MELSEC iQ-R and iQ-F series programmable logic controllers.
GX Works3 is the latest generation of system design and programming software from Mitsubishi Electric, specifically built for the MELSEC iQ-R and iQ-F series. You can manage your entire automation lifecycle—from initial system design and hardware configuration to complex programming and long-term maintenance—within a single, integrated environment. The software focuses on reducing engineering costs by providing a highly intuitive, graphics-based configuration tool that lets you visualize your hardware setup instantly.
You can choose from multiple programming languages like Ladder, Structured Text, and Function Block Diagram to suit your specific project needs. The platform includes a powerful simulation engine, allowing you to test your code and hardware logic in a virtual environment before deploying to the factory floor. This helps you catch errors early, reduce commissioning time, and ensure your industrial processes run smoothly from day one.
