  The EMBL is located at the DESY site in Hamburg and operates 7 beam lines at the DORIS III synchrotron. Currently the EMBL Hamburg constructs three new beam lines at the new PETRA III synchrotron. In the past the level of beam line automation is significantly increased. Control system tasks are changed to more data through put, faster reaction times and require more flexibility. The control electronic has to allow fast feedbacks and precise data synchronization. Sample changer offer higher speed and sample capacity. The transport of videos and the huge amount of experimental data via the control system requires networks with large bandwidth and high efficient control system transport protocols. The EMBL has chosen TINE as beam line control system. TINE features like the multi cast option and the efficient TINE transport protocol help to minimize the network load. The control electronic will be the real time PLC control EtherCat for motor control and data acquisition. Fast data acquisition will be performed with FPGA and PXI electronic. Presented will be the beam line control concept, the control electronic layout and the first finished applications.

  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.

WEX04 An Embedded Distributed System Based on TINE and Windows CE 148

  We present an embedded distributed system based on the integration of the control system (TINE) inside an embedded-PC running Windows CE RTOS. As Windows CE is not Windows and requires a cross-compilation of the source modules, porting TINE to Windows CE turned out to be straightforward, but non-trivial. Having a dedicated Windows CE TINE library allows creating device servers inside the embedded operating system, close to the hardware application layer. The embedded-PC is the master of the hardware line, where different hardware devices are connected through a real-time Ethernet field bus. On the one hand there is a low level control of this hardware performed by a set of programmable logic controllers (PLC) running in fast cycling and on the other hand there is a higher level control performed by the TINE server devices. The server is the responsible of providing an interface to the external world, exporting the functionality of the system through the Ethernet control network. It is also possible that the server acts as a TINE client of other external servers, constituting a network of embedded nodes. We present a practical development that demonstrates the proposed system.

WEZ01 The TINE Common Device Interface in Operation 154

  The Common Device Interface (CDI)* is the primary device layer used in the TINE** control system. It offers a generic, database-driven view of a server’s hardware, where a hardware address, irrespective of the underlying bus, simply appears as a named device, which is accessed via the TINE client API. To date, CDI-supported busses include several CAN implementations, RS232, TwinCat***, Libera****, Siemens PLC, as well as the DESY in-house bus SEDAC. In this paper, we report on the latest features of CDI and more importantly on the first experiences of using CDI in operations, primarily in the PETRA3 pre-accelerator chain and in DC, Servo, and stepper motor control at the EMBL beamlines.

WEP012 A Crystal Centering System with a FPGA Based Position Control Approach for EMBL Beamlines at PETRA III 192

  The EMBL is located at the DESY site in Hamburg and operates 5 beamlines at the DORIS III sotorage 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. In this paper a reconfigurable FPGA based control solution is presented to monitor and analyze in real time beamline experiments. The hardware is suitable to acquire fast and high sensitive electronic signals, analyzing them for feedback closed loops. The system is included in the TINE control system and can be remotely controlled and configured. The control hardware consists of a National Instrument PXI crate equipped with a real time controller and R-series FPGA. The Labview real-time object oriented programming to control the system is presented as well as the adaptation of the hardware to various applications. The solution is shown starting from simulation and then testing on the existing DORIS test beamlines used for PETRA III.

  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.
