Plaxio

Plaxio is a modern desktop Integrated Development Environment (IDE) designed for Programmable Logic Controller (PLC) programming, focusing on efficiency and vendor neutrality. Key features include: • Support for Ladder Diagram, Function Block Diagram (FBD), and Structured Text (ST) • Real-time program simulation • Live tag monitoring • Offline development capabilities • Export to major PLC vendors like Rockwell, Siemens, and Schneider This IDE allows engineers to develop and test PLC logic without being tied to specific hardware or proprietary software. Users can rapidly create complex control sequences, such as motor start/stop, interlocks, and timer logic, using descriptive language to generate complete IEC 61131-3 compliant code. The platform ensures that graphical and code representations remain perfectly synchronized, allowing for seamless switching and editing between visual FBD canvases and underlying structured source. Plaxio is ideal for controls engineers, system integrators, and industrial automation teams seeking a powerful, flexible, and free tool to streamline PLC development, reduce programming time, and enhance collaboration across different vendor environments. It supports a wide range of manufacturers including Mitsubishi Electric, Omron, Beckhoff, ABB, and systems compatible with Codesys.
