  1. JCOP Review 2003 “Other” Activities D.R.Myers, IT-CO

  2. Topics Covered • ATLAS TRT Gas • OPC • ALICE HMPID • CMS B(1) 2 Gas • Vertical Slice • Rack Control • Sub-Rack Control • GIF • High/Low Voltage • Front-End • Cooling & Ventilation • Data Interchange • Miscellaneous D.R.Myers, IT-CO

  3. Motivation • Prototyping and Evaluation (for many) • Everything needs control: • List what could possibly be done in common. • Visit people concerned, • Try to set up a relevant sub-project. • Can be viewed as a disturbance! • But, some successes… • NB SCADA, Gas, etc. covered separately D.R.Myers, IT-CO

  4. ATLAS TRT Gas • R. Barillère & F. Michaud, 1998 • Technology: • Profibus & WAGO modules for I/O (no FB devices) • Applicom for interfacing • BridgeVIEW for supervision (this was pre-SCADA) • Closed loop control with FSM modeling • Conclusions: • Would be advantageous to use PLCs for process control • Would like built-in FSM if possible • OPC would be a good candidate as software interface. D.R.Myers, IT-CO

  5. OLE for Process Control • Ph. Gras, R. Barillère, 1999/2000 • Technology: • Client-Server interface to front-end hardware • De Facto industrial standard based on COM/DCOM • Supervisors come with supplied OPC Clients • In many cases, hardware vendors supply OPC Servers • Conclusions: • Solves “M x N” driver problem (for Windows systems) • Possible to purchase tool kits to help write servers • Useful (in fact unavoidable!) D.R.Myers, IT-CO

  6. ALICE HMPID • H. Milcent & E. Määta, 1998/1999 • Technology: • PLC (Siemens) • OPC interface software • BridgeVIEW for supervision (pre-SCADA) • Conclusions: • Confirmed applicability of two-layer model • Good tools • OPC promising common interface (input to OPC review) D.R.Myers, IT-CO

  7. CMS MSGC B2 Gas • R. Barillère & Lucia Martinez, 1999 • Re-engineer EPICS-based B1 Gas • Use experience gained from ALICE HMPID project • Technology: • PLC (Siemens) • OPC interface software • SCADA (evaluate PANORAMA) for supervision • Conclusions: • Confirmed applicability of PLC/OPC/SCADA model D.R.Myers, IT-CO

  8. Vertical Slice • S. Zelepoukine & CO-FE members, 2001 • Goal: • Look at all elements and costs from sensors up to supervision system • Eight possible solutions reviewed, some in detail • Conclusions: • Provided cost breakdown for sensors, cabling, patch panels, DAQ and interfacing to supervision • Most h/w lacks radiation tolerance and high density • Factor of 5 in cost/channel for 5000 channels D.R.Myers, IT-CO

  9. Rack Project (Control) • P. Maley et al EP/ESS, 2000 • Issues raised: • Choice of racks, power supplies, cooling, safety chains… • Conclusions: • Power distribution to be provided by ST-EL • Monitoring hardware based on single PCB with ELMB • Interfacing via OPC • Control via DCS (PVSS) and ST-EL hardware D.R.Myers, IT-CO

  10. Sub-Rack Control • Experiments made a common industrial tender for sub-racks including controls. • Tender specification was conformant with JCOP standards (C. Parkman and EP/ESS) • Conclusions: • Tender won by Wiener • Interface will be via an OPC Server supplied by vendor D.R.Myers, IT-CO

  11. Gamma Irradiation Facility • M. Clayton EP/ESS, 2000/02 • Goals: • Improve GIF facility • Test Bed for JCOP technology • Conclusions: • Slow progress due to insufficient manpower, cabling problems, etc. • CAN and Profibus backbone installed • Environmental parameters monitored & published • A number of networking-related problems uncovered D.R.Myers, IT-CO

  12. HV and LV Power • No project, but a document was produced covering (probable) user requirements (1998) • CAEN used URD as a basis for controls functionality in their new SY1527 range. • Collaboration over use of OPC interface with CAEN, as well as ISEG and Wiener • Attempting to standardize CAN interfacing • Conclusion: • Adoption of standard OPC interfaces • Companies responsible for servers! D.R.Myers, IT-CO

  13. Front-End Systems • IT-CO has available an Object-Oriented framework for F-E software development which has been used by F-T experiments • Conclusion: Experiments wish to develop their own software. • DIM adopted as intermediate standard for connection of F-E systems if required • DIM interface to PVSS developed by C. Gaspar • First-line support by IT-CO • Currently no further work foreseen D.R.Myers, IT-CO

  14. Cooling & Ventilation • Separate C & V project “JCOV” set up • JCOP to advise on controls issues • “Grey area” identified between primary cooling and sub-detector systems • Conclusions: • Operational control of sub-detector cooling by expts. • Cooling-loop design & process control by ST/CV D.R.Myers, IT-CO

  15. External Systems • Goals: • Provide communications with external systems:LHC Machine, TCR, C&V, Magnets, (DSS?), etc. • Procedure: • Collaborate with LDIWG (!) on definition of D.I.P. • Provide driver for PVSS • Develop (generic) applications within Framework • Planning: • To be handled by Framework Advisory Board D.R.Myers, IT-CO

  16. Miscellaneous Items • Document produced on Database Issues • These are still to be addressed… • Component-Ware • Investigations made (1998) and approach dropped • Test Bench • IT-CO has set up Front-End, DSS & SCADA Labs: • Covers: Fieldbuses, PLCs, OPC, PVSS, DSS • Hands-On Machines • Demonstration Machines with Tutorials D.R.Myers, IT-CO
