  3. Need for cf-update • How to add new channels • Without having to learn the client api’s • How to manage existing channels • Orphaned channels • Moved channels • Automatically handle some attributes/properties of channels • hostName • iocName

  4. cf-update v2.0.0 • The properties currently managed with cf- update –  hostName –  iocName –  pvStatus : Active or InActive –  time : The last time the above properties where updated

  5. Example st.cmd iocInit dbl > record.dbl system “cprecords.dbl /cf-update/$HOSTNAME.$IOCNAME.dbl”

  6. Under the Hood • The cf_monitor daemon monitors $(CF_UPDATE_DIR) directory and envokes an updare task when • A new *.dbl file is created in the dir • An existing *.dbl file is modified • The update task handles • Uses the filename to obtain the hostName, iocName property values and defines time as the time when the file was modified • New channels – creates new channels with hostName, iocNameproperties • Orphaned channels – the hostName, iocName properties are retained for debugging purpose but the pvStatus is set to inactive • Moved channels – ensures that the hostName, iocName properties are update when channels are moved • Unchanged channels • All other existing properties and tags are left unaffected

  7. Controls Properties

  8. Physics Properties

  9. Physics applications • The High level applications tend to prefer a hierarchical view of the control system where they can group channels by type (such as BPM, horizontal corrector) or location • accelerator physics high level application APHLA (python) • ChannelViewer • Channel line plot • Waterfall plot • Channel Orchestrator

  10. ChannelViewer

  11. Channel Line Plot

  12. Channel Orchestrator

  13. Channel Orchestrator

  14. ChannelFinder Service • ChannelFinder is now a pvmanager service

  15. ChannelFinder in BOY

  17. Service Button

  18. Channel Finder service button

  19. Auto-complete

  20. Future plans • Manage additional properties and tags automatically • Integration with NameService/NameValidator • Replace channel widgets with general purpose widgets using pvmanager services and formula • Integration with MASAR
