The Software Interlock System (SIS) is a JAVA software project developed for the CERN accelerators complex. The core functionality of SIS is to provide a framework to program high level interlocks based on the surveillance of a large number of accelerator device parameters. The interlock results are exported to trigger beam dumps, inhibit beam transfers or abort the main magnets powering. Since its deployment in 2008, the LHC SIS has demonstrated that it is a reliable solution for complex interlocks involving multiple or distributed systems and when quick solutions for un-expected situations is needed. This paper is presenting the operational experience with software interlocking in the LHC machine, reporting on the overall performance and flexibility of the SIS, mentioning the risks when SW interlocks are used to patch missing functionalities for personal safety or machine protection.

This paper presents an overview of beam based feedback systems at the LHC at CERN. It will cover the system architecture which is split into two main parts – a controller (OFC) and a service unit (OFSU). The paper presents issues encountered during beam commissioning and lessons learned including follow-up from a recent review which took place at CERN
