CERN’s Accelerator Controls group launched a project in 2003 to develop the new CERN accelerator Real-Time Front-End Software Architecture (FESA) for the LHC and its injectors. In this paper, we will report on the status of this project, prior to the imminent start-up of the LHC. After describing the main concepts and components of the infrastructure, we will present how we have capitalized on the different technical choices, by showing the framework’s flexibility through the new functionalities recently introduced, such as: Transactions, Diagnostics, Monitoring, Management of LHC Critical Settings, communication with PLC devices and Composition. To conclude we will present the extensions foreseen in the short term.
