    "abstract": "By the end of the nineties, the power converter control system (Mugef) of the\nCERN proton accelerator (SPS) had undergone a complete modernization. This\nresulted in newly developed hardware for function generation, measurement and\nI/O in a VME environment, under the LynxOS real-time operating system. This has\nprovided a platform on which extensions can be developed for future operation\nin the Large Hadron Collider (LHC) era. This paper describes some of these\nextensions, in particular a fast Surveillance and Interlock system for\nmonitoring the power converter output currents. This will be mandatory for the\nsafe operation of the SPS transfer lines TI2 \u0026 TI8 to LHC and for similar\napplications in the future. The strategies employed to cope with various\nfailure modes of the power converters and the timely activation of the\ninterlock are outlined. The new SPS controls infrastructure now under\ndevelopment, will give rise to new modes of operation for the Mugef systems.\nIntegration with the proposed middleware must be undertaken in a structured\nevolution, while retaining compatibility with the current usage.",
