  1. The Control System For LHC Hardware Commissioning The Application Infrastructure Eugenia Hatziangeli Reporting on the work of AB/CO and AB/OP

  2. Contents • Our Strategy • Applications for LHC hardware commissioning • Common services • Issues • Conclusions

  3. Our Strategy • Choose appropriate technology • For high level controls, use software developed for TI8,TI2, LEIR • For new systems apply industrial solutions when appropriate • Cryogenics, Quench Protection, Powering Interlocks • Integrate together high level with industrial controls • Develop once, using a simple, iterative development model • Use standard components where possible • Common CO general services (Alarms, Logging, FDs, PM, …) • Validate complete integration of our systems • Build on every possible controls milestone • Dry runs • Improve the functionality • Go from simple to more general • Solutions deployed progressively to meet successive milestones

  4. Contents • The strategy • Applications for LHC hardware commissioning • The Scope • Industrial Controls - UNICOS • High Level Controls - LSA • Common services • Issues • Conclusions

  5. The Scope - LSS8L • LSS8L: commissioning first magnets in LHC • 2 powering subsectors • 29 electrical circuits • Vacuum, Cryogenics, Power converters, Quench protection (QPS), Powering interlocks (PIC) An excellent milestone for controls, “the fun part!”

  7. Industrial Controls - Cryogenics • Production Cryogenics (surface, UX, UJ) controls already deployed • Present functionality adequatefor HWC • > 50% developed • 30% deployed • System validation test done and it is operational • Tunnel Cryogenics (QRL, magnets, DFB) controls • Same framework as the Production Cryogenics (AT/ACR & AB/CO) • For supervision no coding, just configuration • 1st version for QRL test ready in Jun ‘05 • 1st version for LSS8L test ready in Nov ‘05

  8. Industrial Controls - PIC • Under development but delayed - lost the fellow responsible for the work • Prototype version ready in Jul ‘05 • First operational version available in Aug ‘05 (lab tests) • Final operational versions is needed for LSS8L Dec ’05 Powering Subsector Management of powering permits

  9. Industrial Controls - QPS • Test setupapplication(AT/MEL)ready May ‘05for surface tests (now) • end May ‘05fully operational • 2nd version supervision, compliant to the LHC naming conventions ready end Aug ‘05 • Full controls will be operational Sep ‘05 • Final operational versions is needed for LSS8LDec ’05 Overview

  10. Industrial Controls - Vacuum • Same application for SPS, TI8 and TI2 • The application for HWC ready - by end May ‘05 • Application must be deployed operationally for QRL tests Jun ‘05 Overview QRL & Cryo vacuum sectors Pressure profile QRL & Cryo Vacuum

  11. High Level Controls - LSA • What is available for the control of electrical circuits • On-line control database • Layout, configuration, settings, equipment description • Settings Generation • Generation of the commissioning functions based on the optics • Settings Management • Functions or values for all parameters (physics to hardware) • All modification recorded, roll-back possible • Hardware Exploitation • Equipment Control, Measurements, Interface to PC • Successfully deployed in TT40, TI8, LEIR Generic Equipment Control Settings Visualization Measurement of PCs

  12. High Level Controls - The Sequencer Sequence Monitoring 24HrsHeatRuns with ramp graph Circuits,PCs and test selection • A dedicated set of instructions developed for HWC • The following tests are implemented • 24 hour heat runs test • PC_permit test • PC_permit including B2 pc_permit1 and 2 • Powering failure • Circuit Quench via QPS • PC discharge request • PIC discharge request • PIC fast abort request via PIC • First version in place and tested Circuit Quench via QPS Battery Tests

  13. Contents • The strategy • Applications for LHC hardware commissioning • Common services • Issues • Conclusions

  14. Common Services for HWC • TT40, TI8, Cryo, Vacuum • TCR, LEIR • CPS,SPS,LEIR • Some experience from TT40 • TI8 • LEIR • CPS, SPS, SM18 • LHC Logging service • Alarm (LASER) system • Timing • Post-Mortem • Data collection • Event analysis • Fixed displays • Console manager • elogbook

  15. Post Mortem - Data Collection • The Process • Source systems push PM data to PM server • PM server saves data in a standard format • PM analysis tools access those files • Where we are now • Data collection chain is testedwith PC system PM data • Prototype PM browserin place • Issues with CMW server seen during PC tests are being investigated

  16. Post Mortem - Analysis QPS PIC PC • Four level analysis • Event analysis • Interaction analysis (QPS-PIC, PIC-PC) • Per system analysis (QPS, PIC, PC) • Data Verification • Where are we now • UR are under discussion (SACEC) • Start with the QPS as a pilot analysis • PM analysis needed in Dec ‘05 for the Interlock & Powering tests

  17. Fixed Displays • Implementation based on TI8 Fixed Displays (FD) • Graphical representation of data in place • Add functionality for text representation • Prototype with PC in Jun ‘05 • 1st basic version in Jul ‘05

  18. Contents • The strategy • Applications for LHC hardware commissioning • Common services • Issues • Data Exchange • New Software Development • User Requirements • Resources • Computer Security • Conclusions

  19. Issues - Data Exchange • Between different systems • QPS to PIC (QPS gives the power permit) • Tunnel Cryogenics system with Vacuum • Sequencer with QPS, PIC, PC • Fixed Displays data collection (Cryo, Vacuum, PC, CV,…) • Communication packages • CMW, AB/CO standard for all CO communications • CMW -> PVSS interface available in Aug ‘05 [FD, Sequencer] • PVSS -> CMW interface available, prototype in place [QPS, PIC] • DIP, CERN-wide for inter-domain data publication • DIP <-> PVSS interface available(IT/CO) but not yet operational [Vacuum, QRL]

  20. Issues - New Software Development • Many new applications under development • Tunnel Cryogenics controls • QPS • PIC • Post Mortem • Fixed Displays • Data exchange communication interfaces • Software will be ready in time for HWC, but a challenge for validation • Use simulation for tests and debugging • Connect to real system when available

  21. Issues - User Requirements • Tight links with SACEC for the cold circuits • All other systems yet to be studied!! • Know what is needed for • Short circuit tests • 24-hour heat run • Interlock tests • Working on • Powering tests • Post Mortem requirements

  22. Issues - Resources • Same people - competing activities • LEIR - HW and beam commissioning [Apr-end ‘05] • CNGS [end ‘05] • LHC Inj. Lines commissioning (TI2) [Jun 05] • CCC [2nd half ‘05] • SPS & CPS start up with major changes [end ‘05] • Due to tight resources, we aim at basicfunctionality and improve progressively • Improvements need qualified software engineers; it takes several months for newcomers to understand accelerator needs

  23. Issues - Computer Security • New security policy on TN from Jan ‘06 -> Isolate from hackers • No major implications on HWC and FCR if on TN • For clients on GN no direct access to equipment on TN • Dedicated Gateways will provide connectivity • Formal authorisation for new equipment on TN • NoWireless & DHCP on TN

  24. Conclusions • The hardware commissioning is a major milestone and a new phase for controls • Controls critical for HWC, LSS8L important for Controls • It is the first time that high level and industrial based controls will be integrated • Integration with CMW is a critical issue • A lot of software is now in place and validated • Use existing software where possible but new software is required and very high pressure on specific resources • Dry runs for all critical systems • Requirements studies for systems not covered by SACEC should start in good time • HWC has a tight schedule but so has AB/CO • Controls availability and automation are essential to meet schedule and save time • Implement basic functionality and improve progressively
