Abstract
Information is communicated to a process control device by performing a process that includes the step of heating a component, the component having structured volumetric regions. When the component is heated, structures present in the volumetric regions radiate in the infrared spectrum, allowing the structures to be distinguished by an infrared sensor. The structures, formed by elevations or depressions, form a machine-readable identifier, which can be used as an originality identification means for the component. Since the identifier can be determined in situ during a heating process, the process control device can recognize whether correction values are to be used for the thermal treatment of a substrate.
