This paper presents the approach used at CERN (European Organization for Nuclear Research) for the re-engineering of the control systems for the water cooling systems of the LHC (Large Hadron Collider). Due to a very short, and therefore restrictive, intervention time for these control systems, each PLC had to be completely commissioned in only two weeks. To achieve this challenge, automatic generation tools were used with the CERN control framework UNICOS (Unified Industrial Control System) to produce the PLC code. Moreover, process dynamic models using the simulation software EcosimPro were developed to carry out the ‘virtual’ commissioning of the new control systems for the most critical processes thus minimizing the real commissioning time on site. The re-engineering concerns around 20 PLCs managing 11000 Inputs/Outputs all around the LHC. These cooling systems are composed of cooling towers, chilled water production units and water distribution systems.
