LHC GCS: A HOMOGENEOUS APPROACH FOR THE CONTROL OF THE LHC EXPERIMENTS GAS SYSTEMS
2003
The LHC Gas Control System (LHC GCS) project has been initiated to provide the 4 LHC experiments (ALICE, ATLAS, CMS and LHCb) with control for their 21 gas systems. To reduce the effort in the development, maintenance and operation phases, a homogenous approach has been selected. It is based on industrial components: a Supervision Control And Data Acquisition (SCADA) system (ETM’s PVSSII), Schneider Programmable Logic Controllers (PLC), Profibus, CAN and a library (UNICOS) to develop applications in both PLCs and PVSS. This paper describes the milestones that have been achieved: feasibility study, analysis, design and the results obtained with the first system. In addition details will be given about the LHC GCS framework.
