The Elettra control system has been running since 1993. The controllers of the storage ring power supplies, still the original ones, have become obsolete and are no more under service. A renewal to overcome these limitations is foreseen. A prototype of the new controllers based on the BeagleBone embedded board and an in-house designed ADC/DAC carrier board, has been installed and tested in Elettra. A Tango device server running in the BeagleBone is in charge of controlling the power supply. In order to transparently integrate the new Tango controlled power supplies with the existing Remote Procedure Call (RPC) based control system, a number of software tools have been developed, mostly in the form of Tango devices and protocol bridges. This approach allows us to keep using legacy machine physics programs when integrating the new Tango based controllers and to carry out the upgrade gradually with less impact on the machine operation schedule.

Sardana is a software suite for Supervision, Control and Data Acquisition in scientific installations. It aims to reduce cost and time of design, development and support of the control and data acquisition systems [1]. Sardana, thanks to the Taurus library [2], allows the user to build modern and generic interfaces to the laboratory instruments. It also delivers a flexible python based macro environment, via its MacroServer, which allows custom procedures to be plug in and provides a turnkey set of standard macros e.g. generic scans. Thanks to the Device Pool the heterogeneous hardware could be easily plug in based on common and dynamic interfaces. The Sardana development started at Alba, where it is extensively used to operate all beamlines, the accelerators and auxiliary laboratories. In the meantime, Sardana attracted interest of other laboratories where it is used with success in various configurations. An international community of users and developers [3] was formed and it now maintains the package. Modern data acquisition approaches guides and stimulates current developments in Sardana. This article describes how the Sardana community approaches some of its challenging projects.

Cosylab was established 13 years ago by a group of regular visitors of the PCaPAC. In the meantime, it has grown to a company of 90 employees that covers the majority of accelerator control projects. In this talk, I will present the most interesting developments that we have done in the past two years on a very different range of projects and I will show how we had to get organized in order to be able to manage them all. The developments were made for labs like KIT, ITER, PSI, EBG-MedAustron, European Spallation Source, Maxlab, SLAC, ORNL, GSI/FAIR but also generally for community software like EPICS, TANGO, Control System Studio, White Rabbit, etc. And they range from electronics development to high level software: electric signal conditioning and interfacing, timing system, machine protection system, fibre-optic communication, linux driver development, core EPICS development, packaging, high performance networks, medical device integration, database development, all the way up to turnkey systems. Efficient organisation comprises a matrix structure of teams and groups versus projects and accounts, supported by rigorous reporting, measurements and drill-down analyses.

Advances in computational performance allow for fast image-based control. To realize efficient control loops in a distributed experiment setup, large amounts of data need to be transferred, requiring high-throughput networks with low latencies. In the European synchrotron community, TANGO has become one of the prevalent tools to remotely control hardware and processes. In order to improve the data bandwidth and latency in a TANGO network, we realized a secondary data channel based on native InfiniBand communication. This data channel is implemented as part of a TANGO device and by itself is independent of the main TANGO network communication. TANGO mechanisms are used for configuration, thus the data channel can be used by any TANGO-based software that implements the corresponding interfaces. First results show that we can achieve a maximum bandwidth of 30 Gb/s which is close to the theoretical maximum of 32 Gb/s, possible with our 4xQDR InfiniBand test network, with average latencies as low as 6 μs. This means that we are able to surpass the limitations of standard TCP/IP networks while retaining the TANGO control schemes, enabling high data throughput in a TANGO environment.

The PyPLC [1] Tango Device Server provides a developer-friendly dynamic interface to any Modbus-based control device. Raw data structures from PLC are obtained efficiently and converted into highly customized attributes using the python programing language. The device server allows to add or modify attributes dynamically using single-line python statements. The compact python dialect used is enhanced with Modbus commands and methods to prototype, simulate and implement complex behaviors. As a generic device, PyPLC has been versatile enough to interact with PLC systems used in ALBA [2] Accelerators as well as to our Beamlines SCADA (Sardana [3]). This article describes the mechanisms used to enable this versatility and how the dynamic attribute syntax allowed to speed up the transition from PLC to user interfaces.

The precise motion control in high resolution is one of the necessary conditions for making high quality measurements at beamline experiments. At a common ANKA beamline up to one hundred actuator axes are working together to align and shape beam, to select beam Energy and to position probes. Some Experiments need additional motion axes supported by transportable controllers plugged temporaly to a local beamline control system. In terms of process control all the analog and digital signals from different sources have to be verified, leveled and interfaced to the motion controllers. They have to be matched and calibrated in the control systems configuration file to real physical quantities which give the input for further data processing. A set of hard- and software tools and methods developed at ANKA over the years is presented in this paper.

Tango offers an efficient and powerful archiving mechanism of Tango attributes in a MySQL database. The tool Mambo allows an easy configuration of all to be archived data. This approved archiving concept was successfully introduced to ANKA (Angströmquelle Karlsruhe). To provide an efficient and intuitive web-based interface instead of complex database queries, the TANGO Archiving System was integrated into the “Advanced Data Extraction Infrastructure ADEI”. ADEI is intended to manage data of distributed heterogeneous devices in large-scale physics experiments. ADEI contains internal pre-processing, data quality checks and an intuitive web interface, that guarantees fast access and visualization of huge a data sets stored in the attached data sources like MySQL databases or data files. ADEI and the Tango archiving system have been successfully tested at ANKA's imaging beamlines. It is intended to deploy both at all ANKA beamlines.

Web2cToolkit is a collection of Web services. It enables scientists, operators or service technicians to supervise and operate accelerators and beam lines through the World Wide Web. In addition, it provides users with a platform for communication and the logging of data and actions. Recently a novel service, especially designed for mobile devices, has been added. Besides the standard mouse-based interaction it provides a touch- and voice-based user interface. Web2cToolkit is currently undergoing an extensive renovation and upgrading process. Real WYSIWYG-editors are now available to generate and configure synoptic and history displays, and an interface based on 3D-motion and gesture recognition has been implemented. Also the multi-language support and the security of the communication between Web client and server have been improved substantially. The paper reports the complete status of this work and outlines upcoming development.

Today at SOLEIL, our end users requires that GUI applications display data coming from various sources: live data from the Tango [1] control system, archived data stored in the Tango archiving databases and scientific measurement data stored in HDF5 files. Moreover they would like to use the same collection of widgets for the different data sources to be accessed. On the other side, for GUI application developers, the complexity of data source handling had to be hidden. The COMETE [2] framework has been developed to fulfil these allowing GUI developers to build high quality, modular and reusable scientific oriented GUI applications, with consistent look and feel for end users. COMETE offers some key features to software developers: - A data connection mechanism to link the widget to the data source - Smart refreshing service - Easy-to-use and succinct API - Components can be implemented in AWT, SWT and SWING flavors This paper will present the work organization, the software architecture and design of the whole system. We’ll also introduce the COMETE eco-system and the available applications for data visualisation.
