        "overview": "Beremiz is an IDE and runtime for machine automation that targets any processor, from a microcontroller to an industrial controller or a Linux PC. The PLCopen editor writes ladder (LD), function block diagram (FBD), sequential function chart (SFC), instruction list (IL) and structured text (ST) programs and stores them as PLCopen XML.\n\nThe source is hosted on GitHub and was last pushed in September 2026. The README describes a Windows installer and a Snap package for Linux. The IDE is licensed under GPLv2 or later, the Python runtime under LGPLv2.1, and the C++ runtime under GPLv3. Beremiz suits teams that want an open IEC 61131-3 toolchain. Teams that need certified controller tooling from a device vendor should check the vendor's own environment.",
