Sumario:The Large Hadron Collider’s Cryogenic Control System makes extensive use of several databases to manage data appertaining to over 34,000 cryogenic instrumentation channels. This data is essential for populating the software of the PLCs which are responsible for maintaining the LHC at the appropriate temperature. In order to reduce the number of data sources and the overall complexity of the system, the databases have been rationalised and the automatic tool, that extracts data for the control software, has been simplified. This paper describes the main improvements that have been made and considers the success of the project.
