Method and system for connecting a controller for a machine to a higher level IT system

摘要

The method involves providing an integration layer between a controller and a higher-level information technology (IT) system. A controller image of the controller is generated in the layer. The image from the IT system is accessed through a controller data access (CDA) interface, where the layer comprises a configuration file that defines characteristics of the controller image. Controller-relevant data is automatically generated with the controller for creating the controller image. The controller-relevant data or data derived from the controller-relevant data is transmitted to the layer. An independent claim is also included for a system for connecting a controller for a machine or plant to a higher-level IT system.
