A device for coupling a machine, in particular a machine tool, having a number N of data sources for providing data of the machine in data source-specific file formats having a plurality of applications is provided. The device includes a transformation unit, which is designed to transform data of one of the N data sources present in one of the data source-specific data formats to data of a generic semantic data model for at least one of the applications and data of one of the applications present in the generic semantic data model to data of one of the data source-specific data formats for one of the N data sources. The transformation unit thus advantageously establishes data interoperability between the respective application and the respective data source of the machine. Also provided is a method and to a computer program product for coupling a machine to a plurality of applications.
