    FDL sponsors Beremiz development

    The Libre Endowment Fond has sponsored Beremiz development at the end of 2025.

    FDL The Libre Endowment Fond is a non-profit that sponsors long-term maintenance and development of mission-critical Free Software.

    Organizations and institutions can donate tax-deductibly to support essential projects while maintaining influence over their roadmaps.

    Thanks to their dedication, Beremiz now has improved support for OPC-UA.

    C Code Changes

    The OPC-UA client is now running in a separate thread, preventing blocking of the main PLC cycle in case of errors.

    This also fixes an issue where the PLC could not start if the OPC-UA client could not connect to the server at startup.

    UI Changes

    The IDE now supports adding user-defined types directly from the UI, without needing to find an OPC-UA server.

    Additionally, both IdType and IEC fields have a dropdown menu to select only one of the valid options available.

    Support for wxPython 4

    wxPython is a cross-platform GUI toolkit for the Python programming language. It allows Python programmers to create programs with a robust, highly functional graphical user interface, simply and easily. It is implemented as a set of Python extension modules that wrap the GUI components of the popular wxWidgets cross platform library, which is written in C++.

    As for python 2, wxPython 3.x is depricated. Supporting wxPython 4 is a necessary step in the migration to python 3.
