Method and device for the programming and configuration of a programmable logic controller

A computer-implemented method for the programming and configuration of a programmable logic controller, the method comprising:

• locating a configuration tool in a programming tool, wherein the configuration tool includes a module in an IEC61131 language;
• integrating at least one further module into the configuration tool;
• and
• executing the programming and configuration of the programmable logic controller in a high-level language using a C-Code editor by means of the at least one module,
• wherein the at least one further module is configured to provide a definition of interfaces between an IEC61131 code and a high-level language code and a configuration of the high-level language code;
• and
• configuring the high-level language code by:
• providing a library management configured to set up user-defined libraries and to be managed using a high-level language;
• configuring a library project in the high-level language, wherein the library project includes a mapping of hardware connectable to the programmable logic controller in an IEC 61131-3 interface;
• editing the user-defined libraries and the library project using a high-level language editor and generating an application library from the user-defined libraries and the library project in an application module with C-Code implementation not visible to the user using a compiler and additional library-specific header files;
• adding the generated application library, which is not visible to the user, to the target project code, and
• storing the target project code and the generated application library in the programming tool of the programmable logic controller.
