  In the year 2006, a first operational version of a new Java-based Software Interlock System (SIS) was introduced to protect parts of the SPS (Super Proton Synchrotron) complex, mainly CNGS (CERN Neutrinos to Gran Sasso), TI8 (SPS transfer line), and for some areas of the SPS ring. SIS protects the machine through surveillance and by analyzing the state of various key devices and dumping or inhibiting the beam if a potentially dangerous situation occurs. Being a part of the machine protection, it shall gradually replace the old SPS Software Interlock System (SSIS) and reach the final operational state targeting LHC (Large Hadron Collider) in 2008. The system, which was designed with the use of modern, state-of-the-art technologies, proved to be highly successful and very reliable from the very beginning of its existence. Its relatively simple and very open architecture allows for fast and easy configuration and extension to meet the demanding requirements of the forthcoming LHC era.
