Abstract: The invention relates to a method for providing data access to a technical facility (10), in particular a machine and/or an installation, wherein the technical facility (10) is connected to a data-processing device (16) via a network (18) by means of a data-transmission interface. By means of the data-processing device (16), a digital twin (20) of the technical facility (10) is provided, the digital twin (20) representing modifiable software components of the technical facility (10). A specific UUID is allocated to each of the digital twin (20) and the technical facility (10), a communication between the digital twin (20) and the technical facility (10) being made possible via the network (18) by means of the UUID. The data-processing device (16) provides an access option for access by third parties (24) to data of the digital twin (20) that relate to software components of the technical facility (10) that are represented by the digital twin (20).
