DCS hardware architecture

• Supervisory level
• PVSS Linux Suse 6.0 (initially), NT 4.0
• 5 graphical interfaces at the same time
• 2 systems
• production run-time use
• development

4
DCS hardware architecture

• Front-end level
• re-use existing software DIM
• PLC, fieldbus OPC
• front-end from IT-CO integrated within PVSS
• VME CAEN, WIENER fan-tray
• LynxOS CPU gt Linux VMIC CPU.
• PC-CAMAC

5
DCS software

• as result from interview
• common hardware elements
• analog input, HV channel, etc.
• common software requirements
• access to HV, etc.
• configuration HV channel, alarms, etc.
• operational mode, etc.

6
DCS software

• library of common elements
• analogue input, SY127, etc.
• definition, configuration
• behavior
• run-time graphics
• Tree hierarchy
• action propagation

DCS software

• limited to classic slow control
• not including run-control, detector performance,
  etc.
• no customized graphics

Ready for May 2000 (1)

• DIM-PVSS
• connection
• configuration
• OPC-PVSS
• connection
• configuration
• remote access with PVSS software
• PLC access OPC

9
Ready for May 2000 (2)

• Analogue/digital input-output
• PVSS definition, configuration, run-time panels
• SY127 access
• re-use from the IT-CO work on the LHC framework.
• IT-CO front-end

Summary

• Good progress being made
• Question
• When will you really need the first prototype?
• Remember Final application to be done by
  COMPASS!!!!
• (with help from IT-CO, of course)
