With increasing complexity of the scientific instruments and their infratructure also the demands with respect to the required control systems and their flexibility have grown.[[BR]][[BR]]For MATISSE, the "Multi-!AperTure mid-Infrared !SpectroScopic Experiment" for the Very Large Telescope, MPIA applied for the first time PLCs for supervising the instrument's two cryogenic systems, for controlling its calibration light sources and for reading-out sensors on the optical bench. [[BR]][[BR]]In this talk Michael Lehmitz gives an introduction to PLC-based control technology and presents, via a live-demo, the performance of the MATISSE system.[[BR]][[BR]]Talk: German[[BR]]Slides: English[[BR]]Questions: German, English || |
