  1. FAIR Accelerator Controls Strategy XXIII PANDA Colaboration Meeting 11. Dez. 2007 U. Krause

  2. Accelerator Control • Synchronized operation of equipment • Ramp magnets, RF simultaneously • Tracking tolerance ~10 µs max • Pulse-to-pulse switching • Different beams in successive cycles • Specific set data • Accelerator modelling • Equipment: Magnets, RF generators • Each specific ramps • Operators: Handle physical parameter • Beam energy • Extraction time • Tune • ...

  3. Distributed Decentralized System operator terminals background services databases application communication middleware device presentation (no real-time) stand alone control engine synchronized control engine timing: event generator sequence control equipment control (real-time) timing events Control object Control object Control object Control object Control object equipment modeling modeling modeling sub-system I/O I/O equipm. equipm. equipm. equipm.

  4. Synchronization: Central Timing Sequence Control LPC A EXP 1 LPC B EXP 2 LPC C Timing Generator C Timing Generator A Timing Generator B Experiment 2 Experiment 1 Precision of General Timing: 1 µs (100 ns ?) Sufficient for nearly all tasks in accelerator controls Higher precision: Dedicated systems (e.g. BuTiS)

  5. Slow Controls • Handling valves, pumps, motors, DC power supplies, ... • Not primary focus of accelerator controls • At least at puls-to-pulse switched facilities • GSI accelerator controls, FESA / LSA (CERN) • Widely used in industrial environments • Many commercial products • SCADA-systems • PLCs

  6. CERN: UNICOS • Statement CERN: • No off-the-shelf system covers needs of big installations • CERN develops framework UNICOS: UNified Industrial COntrol System • based on commercial products • SCADA: PVSS ETM professional control • PLCs: Siemens, Schneider • not closely tight to dedicated systems • to fit well into accelerator control environment

  7. Industrial Control Architecture Industrial Supervision Layer Operator Consoles Interface to operators (Monitoring & Command emission) SCADA Servers Real time DB & Archiving Industrial Control layer PLC Process Control Ethernet Network & TCPIP communication services Control Logic Actions PLC Process Control & Field interface Industrial Field layer PLC Field interface control system connection to the process directly or through field-buses Fieldbus Networks Accelerator Presentation Tier Accelerator Middle Tier Accelerator Resource Tier From CERN presentation (P. Gayet, ICALEPCS 2005)

  8. Control Valve AI M value PID An Input position An Output position Equipment module On-Off Valve DI End switch UNIT Equipment module I/O Boards DO position AI M value PID Control Valve AI position Equipment module AO position On-Off Valve DI End switch DO position Process Control Objects I/O devices Field devices UNICOS Break Down • IN UNICOS • Each control module or equipment module is a device • Each device type is an Object Class • Each device is instantiated in the control layer as PLC Object • Equipment modules and Units are embedded in a unique object class : Process Control Object • All PLC Object classes are based on the same model From CERN presentation (P. Gayet, ICALEPCS 2005)

  9. Object status SCADA Proxy PLC Object Human Manual Requ. Requests SCADA Object HMI Process Inputs Parameters Object logic Parameters Information display Auto. Requests Orders Object status Manual Request Process Layers Integration In the Supervision layer a proxy is associated to each object This proxy will present the relevant object info to the operator And allow manual command emission Industrial Supervision Layer Industrial Control Layer From CERN presentation (P. Gayet, ICALEPCS 2005)

  10. UNICOS Applications • Coding • Automated code generation • PLCs: Skeletons, common modules (interlock, configuration, ...) • GUI library • Produce GUIs by drag-and-drop drawing • Instantiation • Instance Generator • Input: EXCEL spreadsheets • Automated middleware configuration

  11. Integration in Accelerator Control From CERN presentation (P. Gayet, ICALEPCS 2005)

  12. FAIR Accelerator Controls CERN controls components are interesting • Front-End control (equipment side): FESA • Control applications (operator side): LSA • Slow controls: UNICOS • Vacuum • Cryogenics • others
