Beckhoff TwinCAT 3

TwinCAT 3 turns your industrial PC into a powerful real-time controller. You can integrate all your automation tasks—from PLC and motion control to safety and HMI—into a single, unified environment. By using the eXtended Automation Architecture (XAA), you can program your machines using familiar industrial standards like IEC 61131-3 alongside high-level languages like C or C++. This flexibility allows you to build more sophisticated machines while keeping your development process streamlined.

You can manage your entire project lifecycle within Microsoft Visual Studio, which simplifies version control and team collaboration. Whether you are building a small packaging machine or a massive production line, the software scales to meet your performance needs. It helps you reduce hardware costs by consolidating multiple controllers into one PC-based system, giving you more processing power for demanding applications like vision processing and machine learning.

GX Works3

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.
