Tools and Components Progress

• PVSS
• Important improvements on performance
• Archiving now on Oracle
• Scalability
• No show-stoppers identified for PVSS
• Guidelines on how to set-up large PVSS system to
  be completed
• Performance tests started on full system
  including hardware
• Framework ( 30 tools and components)
• Fundamental redesign of core part achieved early
  04
• Most of the essential items are ready

2. Detectors progress

• Common solutions
• High Voltage Low Voltage
• Basic solution for Wiener and CAEN devices exist
  some additions and changes are still required
• Finite State Machine behavior developed and
  standardized
• Front End Electronics
• Prototype servers for SPD, TPC and TRD have been
  developed based on a generic device model (FED).
• FEE configuration tools and database are being
  developed
• General Purpose Monitor
• A prototype is already surveying TPC chambers at
  P2..

2. Detectors progress examples

• HMPID A full DCS prototype
• 6 sub-systems with hierarchical control and FSMs
• Interface to DAQ via ECS layer
• Used in test-beams in 2004
• TPC
• 4 sub-systems with FSMs
• Used in test-beam in 2004
• SPD and TRD
• 3 sub-systems
• Used in test-beams in 2004

4. Interface to TRG, DAQ, HLT via ECS

• Interface between DCS and ECS has been defined
• A prototype for HMPID has been implemented and
  tested
• A prototype for TPC is in preparation
• Common online database studied

17
Plans for 2005

• Performance tests of full prototype
• To determine global system configuration
• layout of the PVSS distributed system
• the number of servers and FE computers

Conclusion

• All essential DCS components are available today
• The Back-End system is prototyped
• Each main detector has prototyped several of
  their sub-systems
• All service applications follow schedule
• Detector pre-installation planning fully
  respected by DCS
