Abstract
A method for controlling a technical system via a control system, wherein the control system, after processing a request from an operator, generates a response message to the request such that if a faulty state of the technical system occurs, then associated fault messages are linked in an automated manner to the request and the response message in the time between the request and the generation of the response message, and a corresponding item of information relating thereto is presented to the operator, where the link between the request, response message and fault messages is provided with a digital signature of the operator who made the request to the control system.

A method for preparing a context-sensitive audit trail for a technical system via a control system, the method comprising:
- receiving a request at the control system from an operator;
- processing the request from the operator by the control system;
- generating, by the control system, an appropriate response message to the request if a faulty state of the technical system occurs in a time between the request to the control system and generation of the response message after the processing of the request, associated error messages being correlated in an automated manner with the request and the response message and a corresponding item of information relating thereto being presented to the operator;
- and
- providing a digital signature of the operator who made the request to the control system to a link between the request, response message and error messages.
A control system for a technical system, the control system comprising:
- a processor;
- and
- memory;
- wherein the control system is configured to:
- receive a request from an operator;
- process the request from the operator;
- generate an appropriate response message to the request if a faulty state of the technical system occurs in a time between the request to the control system and generation of the response message after the processing of the request, associated error messages being correlated in an automated manner with the request and the response message and a corresponding item of information relating thereto being presented to the operator;
- and
- provide a digital signature of the operator who made the request to the control system to a link between the request, response message and error messages.
