    Attached is the project file.

    Hi,

    the toolbox provided a quick access to the most common elements and is hardcoded. The function blocks from libraries do not appear in the toolbox. To add a FB from a library you can use an InputAssistant or add an empty box and type library namespace in the type field, following by period and finally by the type name of the block.

    Regards,
    Roman
