About Plaxio

Plaxio is a desktop integrated development environment for industrial automation that combines IEC 61131-3 compliant editors with AI-assisted logic generation. The tool allows engineers to describe control requirements in plain language, and its AI agent produces complete Ladder Diagram rungs, including motor sequences, interlocks, timers, and fault handling, which are inserted directly into projects. It supports multiple programming paradigms through Ladder Diagram, Function Block Diagram, and Sequential Function Chart editors, all synchronized in real time. Projects can be exported losslessly to major PLC vendors such as Rockwell Automation, Siemens, Schneider Electric, and Codesys, with built-in validation to prevent tag mismatches and compliance errors. The platform includes a live tag monitor for real-time editing and forcing of values during simulation, as well as an offline HMI simulator for designing and testing SCADA screens without hardware. Version control is integrated via Git, enabling team collaboration, branching, and rollback of PLC programs treated as code.
