  1. PCaPAC 2000Desy, Hamburg, Germany A Control System Solution for CERN CV Facilities in the LHC Era D. Blanc, M. C. Morodo, CERN, Geneva, Switzerland

  2. Summary • Introduction • A fully industrial SCADA-based solution • The local supervisory station • Operability and maintainability • In practice: The SPS cooling control system • Conclusions and future perspectives D. Blanc, M. C. Morodo, CERN ST-CV

  3. The classic scheme: Specific solutions to optimize the control of each individual process Heterogeneity: very difficult operation, maintenance and evolution of theglobal control environment Now, the aim is: To optimize the control of the individual processes but keeping a global and homogeneous control system solution CV Control System Requirements: Openness, for our heterogeneous environment Networking, for the high geographical dispersion of the processes Powerful local supervisory tools, core of the control system architecture Well-adapted operation and maintenance tools, to improve the process control reliability Integration in the TCR monitoring system, by means of standard interfaces Background and Requirements D. Blanc, M. C. Morodo, CERN ST-CV

  4. Complex processes complicated process control systems Keys towards homogeneity • Standard industrial process control architectures • Flexibility: scalable and modular architectures • Reference Models: coherence and homogeneity • Integration of the Reference Models for particular solutions • Ease the follow-up of thetechnical evolution: up-to-date control systems with a lower maintenance effort • Reuse of well-proven solutions: robustness D. Blanc, M. C. Morodo, CERN ST-CV

  5. Trouble Diagnosis Post-mortem analysis Web-access to layer 2 Archiving station Layer 4: Data handling and web supervision Reference Data Base Data coherence Standardization of interfaces (for remote data configuration) Technical Data Server Layer 3: TCR remote supervision Windows NT Workstations Flexibility Process-customized solutions SCADA: Wizcon Layer 2: Local supervision Cellbus: Ethernet TCP/IP Reliability Availability Maintainability Fieldbus: Profibus DP WorldFIP, CAN PLC: Schneider / Siemens Layer 1: Acquisition and regulation Architecture Data archiving and web-based supervisory tools CERN technical data monitoring Process control and supervision Process regulation D. Blanc, M. C. Morodo, CERN ST-CV

The local supervisory station Wizcon station D. Blanc, M. C. Morodo, CERN ST-CV

  7. Operability and maintainability • Operation-oriented tools (alarms, HCI,…)designed and built by cross-disciplinary teams • Emphasis in validation tests and acceptance procedures • Strong effort in project documentation to keep the in-house knowledge for enabling maintenance and evolution • Software configuration management tools: operational software library and traceability of the upgrades • International standards: IEC 1131-3, IEC 61508, IEC 61506, ... Building control systems to be operational for 10-15 years!!! D. Blanc, M. C. Morodo, CERN ST-CV

  8. The case: SPS Cooling Control System • Scope: • 11demineralised watercooling stations • The primary raw water circuit (BA6 cooling towers) • Objectives: • Design & implement the CS by introducing the new client-server architecture • Integrate the existing equipment for acquisition and Regulation into the new architecture • To provide the required reliability and precision The SPS cooling system is responsible for supplying raw water to the heat exchangers inside the BAs and demineralised water for the cooling of the magnets and machine components D. Blanc, M. C. Morodo, CERN ST-CV

  9. Web access to layer 2 Web access: Only for trouble diagnosis. No remote actions will be allowed!! Central archiving: Local supervisory stations send the data periodically Archiving station Layer 4: Data handling and web supervision Operational data and tools: Definition of the data and tools to serve the TCR operational purposes EC: Software module to integrate the layer 2 in the TCR remote monitoring system Technical Control Room Layer 3: TCR remote supervision HCI: Operation interface tools displaying real-time and archived process data Ethernet TCP/IP Windows NT Workstations Scheduler: For tasks only depending on date-time conditions SCADA: Wizcon DCS: For high performance regulation algorithms, specific calculation and continuous control Layer 2: SPS auxiliary buildings Logic programs: For sequential running of the plants Fieldbus: Profibus DP, FIPIO Regulation: Single-variable and multi-variable control loops, IMC predictive controller and Smith predictor, Fuzzy Logic PLC: Schneider / Siemens Layer 1: SPS cooling stations The case: SPS Cooling Control System D. Blanc, M. C. Morodo, CERN ST-CV

  10. Feasibility study Engineering Data Review Technical Specification Call for tenders Contract follow-up Acceptance tests Operational system The case: SPS Cooling Control System • The studies phase: SPSBA6 prototype • Defining the Problems • Determining the Plant Operating Conditions • Defining the Control Objectives and Strategy • The design phase: • Functional and dysfunctional analysis • Detailed design and simulation • The implementation phase: • Organization: • Project management: CERN ST-CV Group • CERN cross-disciplinary team + Industrial Contractor D. Blanc, M. C. Morodo, CERN ST-CV

  11. Conclusions • The control of the CV processes can be achieved without considering specific solutions and by using a fully Industrial SCADA-based control architecture • The retained solution provides with a high process control precision • A global vision of the CV facilities allows to achieve the required levels of flexibility, coherence and homogeneity in order to assure the follow-up of the technical evolution • The reusability of well-proven solutions results in safer control systems: better reliability (robustness) and availability (maintainability) D. Blanc, M. C. Morodo, CERN ST-CV
