  The EMBL is located at the DESY site in Hamburg and operates 5 beamlines at the DORIS III storage ring. Currently the EMBL Hamburg is in charge to build three new beamlines at the new PETRA III high-brilliance synchrotron radiation source which will commence user operation in 2009. A new multilayer double-crystal monochromator has been developed in house. This has been a real application test for the software and hardware architecture of the new PETRAIII beamlines. An embedded-PC controls the electronic integrated in the EtherCAT real-time Ethernet bus. Inside this PC a logic of PLC’s directly drives the hardware allowing real time data acquisition. The control of the system is distributed and remotely accessible by a connection to a TINE device server. The commissioning phase has been done using a Labview TINE client application. The client is able to perform on-the-fly scans thanks to the PLC's base logic. In the following paper the different pieces of the system are presented as well as an overview of the instrument.

    EMBL, Hamburg
  The EMBL is located at the DESY site in Hamburg and operates 7 beamlines at the DORIS synchrotron. Currently the EMBL Hamburg constructs three new beamlines at the new PETRAIII synchrotron. In the last years the level of beamline automation is significantly increased. In the area of biological beamlines automatic Sample changers were established. We present the control design of the new sample changer offering higher sample capacity, improved sample throughput and flexibility.
