  1. Enrique BLANCO Controls Group: Industrial Systems AB Department, CERN Geneva, Switzerland LHC Cryogenics Control: INTEGRATION OF THE INDUSTRIAL CONTROLS (UNICOS) AND FRONT-END SOFTWARE ARCHITECTURE (FESA) APPLICATIONS

  2. Outline UNICOS + FESA INDUSTRIAL CONTROL

  3. 1.- LHC Cryogenics Architecture LHC cryogenics overview Cryogenic point Cryogenic plant 3.3 km Long Straight Section (Transfer line) LHC tunnel (27 km)

  4. 2.- Cryogenics Control System Instrumentation LHC cryogenics standard cell PI&D (~100 meters) RadTol Signal Conditioners • Large number of sensors and actuators. • Tunnel instrumentation exposed to radiation (custom development to withstand the hostile environment)

  5. 2.- Cryogenics Control System Tunnel Architecture SCADA Data Servers Local & Central Control Rooms Ethernet (TN) PLCs FECs UNICOS FESA WorldFIP Profibus DP TT, PT, LT, EH, DI Ehsp, LTen shaft (~100 m) DP DP DP DP Protected areas PA PA PA PA Alcoves CV TT Radiation areas RadTol electronics Tunnel LSS LSS ARC LHC Tunnel (3.3 Km)

  7. 3.- Frameworks FESA * Ref: “Frond-End Software Architecture”, M. Arruat, et all. (ICALEPCS 07) FESA Application Process Execution • Front-End Software Architecture* • CERN accelerator real-time software model • Deployed to Front-End computers (FECs) running Linux/LynxOS • Cryogenics application processes • WorldFip: Read/Write Worldfip agents • Real-Time action • Device: Calculates devices data (Minimize electronics cards calculations) • Segment: Groups devices and communicates to the PLC • Server: CMW Exchange data

  8. 3.- Frameworks UNICOS P P • UNifiedIndustrial COntrolSystem I/O Channels Process Control Objects (Compressors, feedbox, …) Field Objects (Valves, Heaters, …) UNICOS Logic Instances Specifications CMW interface Long-Term archiving LHC alarm system PLC and SCADA Baseline Generate PLC and SCADA Devices Diagnostics tools Simplified HMI tool to create process synoptics (drag & drop) Placeholders where the control engineer must write the process logic O Operators Process Engineer C O Control Engineer C C

  9. 3.- Frameworks UNICOS Objects design breakdown Sector Cryogenics Process Control Objects 2 elementary cryogenics cells* i =1..8 j =1..18 • In the case of the tunnel the Process Decomposition exercise allows: • Control a basic tunnel equipment (bi-cell) • Reduce the amount of logic to create by using a few templates which will be parameterized and generated automatically (e.g.: Controllers) I/O objects + Controller (field objects) Process Decomposition: Controllers example

  10. 3.- Automatic generation Tools UNICOS & FESA integration Specifications Control Engineer LHC controls Database Generator Generators Devices Synoptics (Tunnel Panels) Devices PLC comms Devices Code FEC comms SCADA comms Deployment: Deployment: Device Design Custom code - device calculations WorldFipcomms. Baseline Baseline FECs FECs PLCs SCADA FESA UNICOS C C C • Minimize hand code activities and focus on specific control logic • Versioning mechanism to trace all the instances and allow different generation speeds • Generation time of a complete LHC sector : ~ 1 day
