Detection of harmful process intent in an intent-based production process

A control device comprising a computer processor configured to execute a method for detection of harmful process intent in an intent-based production process, the method executed by the computer processor comprising:

• providing a machine-readable production model linking an intent model, correlating to process intent, comprising production process functions, constraints on measurable properties on the production process functions, and/or production process function sequences required for the production process, and a process model, correlating to process knowledge comprising a production process behavior;
• determining a safety library of at least one safety process intent, the safety library being protected by security mechanisms to be maintained outside of regular intent-based engineering mechanisms and operation mechanisms, wherein the safety library comprises a general safety library and a project-specific safety library;
• evaluating changes of process intent in view of potentially harmful process intent dependent on the at least one safety process intent;
• providing a report of potentially harmful process intent for auditing based on the potentially harmful process intent, and
• further comprising automatically determining at least one safety process intent from the general safety library suitable for the production process as project-specific safety process intent for the project-specific safety library dependent on the current production process project.
