Abstract
In a method for securely connecting a controller for a machine or plant to a higher-level IT system, an integration layer is provided between the controller and the IT system, a controller image of the controller is generated in the integration layer, and the controller image is accessed from the IT system. The IT system thus always accesses the controller image rather than directly the controller. This prevents malware from gaining access to the controller e.g. via a network.
