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.
