11. Agenda • The CLS Facility • Control System • Remote Access • Safety Critical Software

12. Statistics…. • Over 15,000 Data Points • 40+ Telemecanique Momentum PLCs • 9 Siemens S7 300/400/400 F PLCs • 30+ VME Crates & 1 VME Crate • 60+ IOC for Serial Communication • 500+ Stepper Motors • 5 Servo Motors • 20+ Operator Workstations (http://www.lightsource.ca/operations/controlinstrumentations.php)

13. Architecture • EPICS based DCS • Sub-system control • Machine Protection (Industrial PLCs) • Process Control (Industrial PLCs) • Scientific Data Acquisition (VME) • Motion Control (VME) • Timing System (VXI) • Operator Workstation and Servers • Scientific Linux

14. What is EPICS ? • Experimental Physics and Industrial Control System Platform • A series of tools and libraries for building distributed control system • Originally developed by Los Alamos • Widely used in the Accelerator Control and Radio Telescope Areas • Some industrial use • Open Source (http://www.aps.anl.gov/epics/)

16. Control Room/Areas • Quad Headed Scientific Linux workstations in the accelerator control room and Dual Headed workstations on the beamlines. • Scientific Linux (CERN/Fermilab) (https://www.scientificlinux.org/) • Human Factors Engineering • EPICS Tools • EDM (Display Manager) • Strip Tool (Data Trending) • CLS Specific • Audio Alarm Annunciation • Legacy hard-wired controls from older Linac Equipment

17. Design – LINAC Master Display

18. Moxa • Linux based – Intel X-Scale Processor • EPICS with the asyn driver and older CLS serial drivers • Used extensively for RS-232/422/485 • Commercial-off-the-shelf

19. Orbit Correction • Beam required to stay within the “golden orbit” • Designed for correction at up to 100 Hz • Digital Signal Condition required to suppress electrical noise and mechanical vibration • Protects Chamber from Off-orbit Beam at high current

20. VME • VME hardware connected to a Linux PC. • SIS1100 PCI card <-> fiber optic link <-> SIS3100 VME module • Maps VME backplane to IOC memory. • Advantages: • PC can be physically separated from VME crate. • More than one VME crate per PC. • Multiple applications can access the same crate. • High throughput 25 to 80 Mbytes/sec block transfer. • Using RTEMS Real-time operating system.(www.rtems.org)

21. Online scripting environment • The options: (1) Matlab, (2) SciLab, or (3) root. • Matlab was selected primarily because of the availability of the accelerator toolbox and staff experience. • Matlab is commercial, the accelerator toolbox is open source. • Software originates from ALS and SPEAR III. • Augmented with other CLS specific utilities. • Also being used as a commissioning tool for beamlines. • Special care is required to maintain consistency with other parts of the control system.

22. Timing System • Provides fiber optic signal distribution of triggers. • VXI based hardware • Custom Electronicsused where jitter is a critical factor • Starting to beused for timeresolveexperiments

23. Safety Critical Software • Applications: • Lockup system (ACIS) • Oxygen monitoring • BMIT human studies (under development) • IEC 61508 – SIL 3 based system • Siemens S7/400 F • Redundant Second Chain • Fail-safe design • Independent Verification

24. Motion Control • MaxV VME Controllers • Power Electronics(Parker + others) • Software/HardwareMulti-Axis Control • Average Beamline50-100 motors

25. Beamlines • Beamline Controls are based on the same software and hardware as the accelerator systems. • Each beamline is on a separate virtual network. • The EPICS Gateway provides links between the different networks. • Matlab is used for scripting.

26. Mechanical Services • Telemecanique MomentumPLCs • Ring temperature stabilityrequirement +/- 0.1 C. • Geographically Distributed • Legacy Systems: • Most 1960s equipment upgradedin 2005 • Most 1980s equipment upgradedin 2004 • Limited number of systemsstill using Invensys DMS DCS
