  1. Ken Livingston University of Glasgow Slow Controls

  2. Slow Controls Low Voltages. Thresholds High Voltages Targets Temperatures Slow controls are for Configuring Monitoring Archiving The experiment Magnets Gas pressures

  3. Slow Controls: Core System Experimental Physics and Industrial Control System • Widely used and supported at national labs (eg ANL, BNL) • Drivers for most hardware • Already used for Hall-B / CLAS • Expertise within collaboration • Used at MCC • Lots of on-site expertise • Communication with other control sytems • PCL, LabView

  4. Slow Controls: Hardware Support • A list of “standard” supported hardware has been compiled • Drivers exist (or will be written / updated) • Detector groups strongly encouraged to use this. • Identify non-standard hardware • Develop drivers • Time estimate: 1 person year.

  5. Slow Controls: Front End Control Systems Studio Eclipse-based collections of tools to monitor and operate large scale control systems, such as the ones in the accelerator community. • Developed and used by many big labs (DESY, SNS, BNL) • Maintained and supported • Easy to develop user GUIs • Tool to convert old style .adl GUIs. • Will be used by Hall-D • Much groundwork and testing already done. • CSS already being tested on existing CLAS EPICS

  6. Slow Controls: Alarms Best Ever Alarm System Integrated into CSS • Single table or tree view • Sort by PV, Urgency, Severity .. • Connect with: • Other CSS components • Variable passing, alarm timelines • E log entries • Send alarm PV to other PV tool • Web reports • Will be used by Hall-D • Much groundwork and testing already done

  7. Slow Controls: Alarms – BEAST Technical View IOCs PV Updates (Channel Access, …) Tomcat • Reports Alarm Server Current Alarms: Acknowledged? Transient? Annunciated? Log Messages Alarm Updates Ack’; Config Updates Annunciations Alarm Cfg & State RDB JMS LOG TALK ALARM_SERVER ALARM_CLIENT Alarm Client GUI JMS2Speech JMS2RDB MessageRDB CSS Applications

  8. Slow Controls: Archiving • CSS has integrated archiving • RDB (Oracle, MySQL, PostgresSQL) • Access to timelines etc – like live system. • MCC have developed MYA • MySQL base EPICS Archiver • Already tested and used • Offered as a service to other Halls • CSS or MYA ? • Hall D evaluated options - they will use MYA • MYA integrated into CSS – best of both • MCC developing this • CLAS 12 will use MYA + CSS http://accelconf.web.cern.ch/accelconf/icalepcs2009/papers/wep021.pdf MYA – C. Slominski, Accel

  9. Slow Controls: Summary • Core system: EPICS R3.14 • Work well underway • Supported hardware list produced • Drivers ready within 1 year • Front End: CSS (Control Systems Studio) • Installation and testing in progress. • Alarm: BEAST (Best Ever Alarm System) • To be installed and tested over summer • Archiving (MYA) • To be set up over next year in consultation with MCC
