With its chain of accelerators and its large experimental physics detectors, CERN is one of the world's most important research centres for particle physics. CERN builds and operates a number of classical and advanced technical utilities to serve its research activities. These utilities are generally equipped with industrial control components purchased with the equipment itself. This paper describes some of the utilities and their controls and proposes a strategy for the integration of diverse industrial control systems into a coherent industrial environment of communication and supervision.
