A system for monitoring a technical device. The system has a capturing means for reading in a first visual representation containing information regarding a setting parameter and/or a measurement parameter of a controller to control the technical device. The setting parameter and/or the measurement parameter characterizes a state of the technical device. The system may have a scanning means for detecting a symbol in the visual representation; a database for associating the setting parameter and/or the measurement parameter with the detected symbol; an interface to the controller to capture a value of the setting parameter and/or of the measurement parameter of the controller; and an image generation means for generating a second visual representation coupled to the controller such that information of the setting parameter and/or the measurement parameter is displayed with the first visual representation. The system has an image display means for presenting the generated second visual representation.
