  1. ECALPrototype DCS system using PVSS Günther Dissertori (for Alison Lister) ETHZ 8.7.2003

  2. Contents: • Proposed layout of the DCS • SM0 and SM1 layouts • Status of implemented sub-systems • Conclusions 8.7.2003

  3. Proposed layout

  4. Proposed layout • Separate into 4 sections of sub-detector: EBL,EBR, EEA,EEB • Each section has same structure • 7 sub-systems: HV, LV, Cooling, Precision Temp, Humidity, Laser Monitoring, TSS • Communication to DSS, DAQ and CMS central DCS

  5. SM0 and SM1 layouts ?

  6. Status of implemented sub-systems • DSS monitors the PLCs of the TSS • Internal structure reflecting that of the figure • All testbeam data sent to Oracle devdb. Easy to retrieve data to text files • Only systems not implemented: Laser monitoring and LV

  7. Supervisory System: • Based on FwFSM, Finite State Machine, sends commands, receives states • As a separate PVSS system • Will communicate with all other systems • Implemented into the Hierarchy (FSM) so far for Cooling and HV systems. Others to follow....

  8. Supervisory System:

  9. Status of implemented sub-systems Cooling system: • Ready for testing • Only sends states, does not receive commands, passive monitoring. • Calibration coefficients and limits can be changed from PVSS with a password.

  10. Cooling system main panel:

  11. Status of implemented sub-systems HV: • installed on final PC, long term stability tests started • Need a password to change any settings and turn on/off channels. Precision Temp: • development started: SM0 will have 2 parallel systems: 1 using ELMB, other using Keithley

  12. HV main panel:

  13. Precision Temp main panel: PROTOTYPE ONLY: for the Keithley system!

  14. Status of implemented sub-systems Humidity: • System similar to the Precision Temp, to be implemented TSS: • Implemented by the Belgrade group • Being tested at the moment

  15. Status of implemented sub-systems Communication with DAQ: • Done via an XML file read by a C++ proxy. Communication to PVSS via DIM. (note: not the final system, only for SM0, until the XDAQ system implemented)

  16. Status of implemented sub-systems • LV communication to be defined before a PVSS development can start • Possibility of web-enabling the Oracle database to allow everyone access to the data in the tables

  17. Conclusions • Close to achieve a nearly “complete” PVSS-controlled DCS for SM0 and SM1 • Aim for a complete control by the fwFSM system • SM0 first large scale test for ECAL-DCS • SM0/1 systems as “prototype” for complete ECAL • The feedback from the shifters during the first weeks of SM0 will be very important
