PVSS progress

• New version released (December 03)
• Better performance robustness
• Handling of distributed systems improved
• Oracle archiving delayed to August 04 release
• Scalability
• CERN tests 130 PVSS systems on 15 computers
• Static functionality ok Dynamic behavior yet to
  be tested
• LOFAR project test 115 producer to 5 consumer
  PVSS systems
• Scales well 700 ups/station measured
• Alarm avalanches
• 2 PVSS systems on 2 computers provoking 10000
  alarms on each system
• Result satisfactory

2. Detectors

• Requirements
• Detector URDs have been completed to 75
• Prototyping
• All main detectors have started prototyping their
  sub-systems
• 10 prototypes implemented and working with PVSS
• Common solutions
• High Voltage Low Voltage
• Device drivers have been prototyped for most
  common devices
• State machine behavior has been developed being
  standardized
• Front End Electronics
• Generic device model (FED) has been defined and
  prototyped
• A global configuration scheme has been defined
  and is being prototyped
• General Purpose Monitor
• A prototype solution has been developed
• TPC, HMPID and SPD used as test case

3. Services

• Electricity
• Rack control prototyping has started
• Rack monitor PRR of main component done
• Networks Layout being defined
• Cooling basic design being finalized
• Gas prototype for TPC finalized
• Magnets 1st prototype installed tested
• Infrastructure requirements being defined
• Safety
• Level 1 (DCS) interlocks alarms being def.
• Level 2 (DSS) implemented - being installed
• Level 3 (CSAM) back-end operational,
• sensors being defined

4. Interface to TRG, DAQ, HLT via ECS

• Basic communication scheme has been defined
• Prototype for HMPID has been implemented and
  tested
• Common Technical Design Report has been finalized

14
Plans for 2004

• Setting up a DCS lab
• For development and test of
• DCS infrastructure powered racks, network
  (isolated), computers
• ALICE DCS Back-end system
• Common sub-system solutions
• Available to detector DCS developers
• For DCS reference systems
• Systems to be installed
• Test-beam support
• TPC May 04
• ITS October 04

15
DCS for TPC test-beam in May
16
Plans for 2004

• Pre-installation at surface of P2
• TPC start Dec 04
• HMPID start Dec 04

17
DCS for TPC pre-installation

Schedule Milestones
19
Critical issues

• PVSS scalability
• Dynamic behavior in full scale to be verified
• B-field in UX
• Find solutions for B-field sensitive components
  in the cavern
• Cooling controls
• 11 sizable PLC based systems to be provided by
  TS
• Design, planning and manpower to be verified

20
Conclusion

• Visible progress in all fields of DCS
• All basic back-end components are available today
  
• Transition from requirements design phase to
  prototyping testing phase has taken place for
  all main detectors
• Global planning and milestones respected by all
  main detectors
