Abstract: A method for interchanging real-time data between program modules, includes providing a data storage device and storing meta information in the data storage device, wherein the meta information has at least one variable. The method also provides for at least one description file to be provided and for the data storage device to be configured with the description file. The method also includes providing at least one connector, wherein a connection can be established between program modules via the data storage device using the connector on the basis of a request in the description file, and wherein the program modules are created using identical or different programming languages and can be executed by a real-time operating system. The method also includes interchanging at least one variable between one of the program modules and the data storage device via the connector.
