  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 embedded device controller network is seen as an open-source, two tier framework that allows device controllers to control distributed devices at a 5 kHz rate. This network provides timing and data transmission to support a network of 200 input devices to be read into 30 cell controllers, resolve 200x200 control matrices, send the new outputs to the controllers and settle in 200 usecs. It also supports identification of system conditions at a resolution of 2 usecs and a reaction to system conditions in under 20 μs. This paper discusses the plan for development, characterization, and deployment.

  One of the strengths of the TINE* control system is the ability to easily make ‘rich-client’ applications containing that programming and display logic which is designed to expedite and enhance the operator’s or physicist’s abilities to diagnose problems and correlate results. In particular there are a large number of ‘rich-client’, general purpose applications which offer extensive interactions with the TINE standard servers and subsystems. This includes the TINE archive system, alarm system, post-mortem system, and video system, as well as scope trace analysis, multi-channel analysis and general configuration management. Available now for many years, these diagnostic applications have recently been realized as pure java applications using ACOP** beans. All applications have been honed and refined based on extensive feedback from the application users. We offer here a description of these applications, some of the novel techniques used and focus on those ‘rich-client’ aspects which cannot be achieved by configuring ‘simple-clients’ based on displayer widgets.

TUP020 The JetFsm Data Acquisition Framework, and Proposed Usage for ITER controls, diagnostics, plasma, site 128

  A comprehensive C++ framework, using the HTTP-based 'black box' protocol, has been developed to allow PC-based control, data acquisition and data visualisation of new JET diagnostic enhancements. This framework allows remote and local developers to develop new applications, with extensive code re-use, without needing to re-implement exiting communication, data management or data visualisation functionality. The paper describes the usage of the Windows implementation. The paper also highlights 5 years of experiences in collaborative development using this approach, and details some of the lessons that have been learnt. The 'black box' approach at JET is similar to that proposed for the ITER plant systems delivered in-kind along with their I&C. Extensions to the framework to cater for the ITER model will be proposed.

WEX04 An Embedded Distributed System Based on TINE and Windows CE controls, monitoring 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.

  Implementing Graphical User Interfaces (GUIs) for complex control systems (CS) implies many development challenges, especially for prototyping and refining. We propose to improve current practices by introducing a model-based, domain specific approach to GUI development. Our methodology* is founded on the assumption that most information to be used for GUI prototyping can be derived by the CS specification itself. We use model transformation techniques for automatic generation of a GUI from a domain specific model. We apply the methodology to the CERN CMS Tracker Cosmic Rack as a case study.

  Coldfire processors find an ideal application as compact, low-cost controllers thanks to the extremely low power dissipation and the wide range of embedded peripherals. We report some experiences using commercially available credit-card size boards based on the Coldfire MCF5329 processor and running under Emlix ucLinux.

  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.

  We developed the PoE-based small-size temperature measurement module*. It consists of a CPU card operated by Linux 2.6 kernel and an RTD card equipped with four-channel inputs of 3-wired Pt100 RTD sensors. We have installed the modules into the machine tunnel of the SCSS (SPring-8 Compact SASE Source) prototype accelerator to measure the air temperatures. The measurement seems to be affected by RF nose because the noise level becomes higher when the machine operations start. We have, therefore, redesigned an RTD card to improve noise immunity to realize precise measurement even under the RF noise. The modifications are as follows; using 4-wired Pt100 sensors with shielded twisted cables, and bringing out the analog ground of the RTD card onto an external connector. In addition, we have increased the number of input channels of the RTD card up to 24. The new module can be also driven with PoE. We have successfully improved the noise immunity and showed the good results of about 0.01°C accuracy during the accelerator operations. Because of its compactness and PoE capability, we will apply the new modules to measure temperatures of insertion device magnets at Japanese XFEL.
