	The control system of the Large Hadron Collider cryogenics manages over 34,000 instrumentation channels which are essential for populating the software of the PLCs (Programmable Logic Controller) and SCADA (Supervisory Control and Data Acquisition) responsible for maintaining the LHC at the appropriate operating conditions. The control system specification's are generated by the CERN UNICOS (Unified Industrial Control System) framework using a set of information of database views extracted from the LHC layout database. The LHC layout database is part of the CERN database managing centralized and integrated data, documenting the whole CERN infrastructures (Accelerator complex) by modeling their topographical organization (“layouts”), and defining their components (functional positions) and the relationships between them. This paper describes the methodology of the data validation process, including the development of different software tools used to update the database from original values to manually adjusted values after three years of machine operation, as well as the update of the data to accommodate the upgrade of the UNICOS Continuous Process Control package(CPC).

The control system of the Large Hadron Collider cryogenics manages over 34,000 instrumentation channels which are essential for populating the software of the PLCs (Programmable Logic Controller) and SCADA (Supervisory Control and Data Acquisition) responsible for maintaining the LHC at the appropriate operating conditions. The control system specification's are generated by the CERN UNICOS (Unified Industrial Control System) framework using a set of information of database views extracted from the LHC layout database. The LHC layout database is part of the CERN database managing centralized and integrated data, documenting the whole CERN infrastructures (Accelerator complex) by modeling their topographical organization (“layouts”), and defining their components (functional positions) and the relationships between them. This paper describes the methodology of the data validation process, including the development of different software tools used to update the database from original values to manually adjusted values after three years of machine operation, as well as the update of the data to accommodate the upgrade of the UNICOS Continuous Process Control package(CPC).
