	N. Coppola, J. Tolkiehn, C. Youngman XFEL. EU, Hamburg, Germany
	The European XFEL project is a 4th generation light source producing spatially coherent 80fs short photon x-ray pulses with a peak brilliance of 1032-1034 photons/s/mm2/mrad2/0.1% BW in the energy range from 0.26 to 24 keV at an electron beam energy 14 GeV. Six experiment stations will start data taking in fall 2015. In order to provide a simple, homogeneous solution, the DAQ and control systems group at the European XFEL are standardizing on COTS control hardware for use in experiment and photon beam line tunnels. A common factor within this standardization requirement is the integration with the Karabo software framework of Beckhoff TwinCAT 2.11 or TwinCAT3 PLCs and EtherCAT. The latter provides the high degree of reliability required and the desirable characteristics of real time capability, fast I/O channels, distributed flexible terminal topologies, and low cost per channel. In this contribution we describe how Beckhoff PLC and EtherCAT terminals will be used to control experiment and beam line systems. This allows a high degree of standardization for control and monitoring of systems. Hardware Technology - POSTER

Low latency between data acquisition and analysis is of critical importance to any experiment. The combination of a faster parallel algorithm and a data pipeline for connecting disparate components (detectors, clusters, file formats) enabled us to greatly enhance the operational efficiency of the x-ray photon correlation spectroscopy experiment facility at the Advanced Photon Source. The improved workflow starts with raw data (120 MB/s) streaming directly from the detector camera, through an on-the-fly discriminator implemented in firmware to Hadoop’s distributed file system in a structured HDF5 data format. The user then triggers the MapReduce-based parallel analysis. For effective bookkeeping and data management, the provenance information and reduced results are added to the original HDF5 file. Finally, the data pipeline triggers user specific software for visualizing the data. The whole process is completed shortly after data acquisition – a significant improvement of operation over previous setup. The faster turn-around time helps scientists to make near real-time adjustments to the experiments.

THPPC095	A Proof-of-Principle Study of a Synchronous Movement of an Undulator Array Using an EtherCAT Fieldbus at European XFEL	undulator, controls, electron, software	1292
	S. Karabekyan, A. Beckmann, J. Pflüger, M. Yakopov XFEL. EU, Hamburg, Germany
	The European XFEL project is a 4th generation X-ray light source. The undulator systems SASE 1, SASE 2 and SASE 3 are used to produce photon beams. Each undulator system consists of an array of undulator cells installed in a row along the electron beam. The motion control of an undulator system is carried out by means of industrial components using an EtherCAT fieldbus. One of its features is motion synchronization for undulator cells which belong to the same system. This paper describes the technical design and software implementation of the undulator system control providing that feature. It presents the results of an on-going proof-of-principle study of synchronous movement of four undulator cells as well as study of movement synchronization between undulator and phase shifter.
