Abstract: The present disclosure relates to a method for determining missing and/or incorrectly positioned field device components of a field device using a stored field device configuration, comprising: creating a digital image of the field device, extracting at least one object and its position in the field device from the image, comparing the object and its position with stored images of field device components and their positions in a field device, identifying the object as a field device component and its position based upon the comparison, determining a field device configuration using the identified field device component and its position in the form of a digital code, comparing the determined field device configuration with the field device configuration of the stored image, and determining the missing and/or incorrectly positioned field device components based upon the comparison.

Abstract: The present disclosure relates to an automation technology process control system for controlling at least one field device having an electronic measurement and/or operation unit, including a user interface for operating the electronic measurement and/or operation unit of the at least one field device, characterized in that the at least one user interface is designed as a tangible user interface.
