  The European XFEL is a 3.4km long X-ray Free Electron Laser in the final construction and commissioning phase in Hamburg. It will produce 27000 bunches per second at 17.5GeV. Early 2015 a first electron beam was produced in the RF-photo-injector and the commissioning of consecutive sections is following during this and next year. The huge number and variety of devices for the accelerator, beam line, experiment, cryogenic and facility systems pose a challenging control task. Multiple systems, including industrial solutions, must be interfaced to each other. The high number of bunches requires a tight time synchronization (down to picoseconds) and high performance data acquisition systems. Fast feedbacks from front-ends, the DAQs and online analysis system with a seamless integration of controls are essential for the accelerator and the initially 6 experimental end stations. It turns out that the European XFEL will be the first installation exceeding 2500 FPGA components in the MicroTCA form factor and will run one of the largest PROFIBUS networks. Many subsystem prototypes are already successfully in operation. An overview and status of the XFEL control system will be given.

  For the operation of a machine like the 3 km long linear accelerator XFEL at DESY Hamburg, a safety system keeping the beam from damaging components is obligatory. This machine protection system (MPS) must detect failures of the RF system, magnets, and other critical components in various sections of the XFEL as well as monitor beam and dark current losses, and react in an appropriate way by limiting average beam power, dumping parts of the macro-pulse, or, in the worst case, shutting down the whole accelerator. It has to consider the influence of various machine modes selected by the timing system. The MPS provides the operators with clear indications of error sources, and offers the possibility to mask any input channel to facilitate the operation of the machine. In addition, redundant installation of critical MPS components will help to avoid unnecessary downtime. This paper summarizes the requirements on the machine protection system and includes plans for its architecture and for needed hardware components. It will show up the clear way of configuring this system - not programming. Also a look into the financial aspects (manpower / maintenance / integration) will be presented.
