Transcript and Presenter's Notes

Title: EPICS2ACNET


1
EPICS2ACNET
  • EPICS Obscura (EO)

2
Implementation
  • Process running on IOC
  • like EPICS2TINE
  • Use MOOC replacement framework
  • Speak ACNET protocols to the outside world
  • Speak dbXXX or caXXX protocols locally
  • whichever makes the most sense

3
Advantages
  • Distributed processing (scalable)
  • Supports all ACNET protocols
  • alarms, GETS32/SETS32, FTP, snapshot
  • Supports low level IOC access
  • Upper levels of the control system are unaffected
    (surgical implant)
  • Could be implemented for other types of nodes as
    needed (extensible)
  • Simplicity (e.g. device to node mapping)

4
Questions
  • Should/can we block CA settings?
  • Do we need to support embedded IOCs?

5
Implementation
  • Create mapping database table(s)
  • EPICS name, device index, property, order number
  • Make DABBEL/D80 aware of these devices
  • Download configuration information on boot

6
Conclusion
  • Transparent access to EPICS parameters
  • No high level overhead incurred
  • database lookups, additional processing code
  • Atomic solution
  • everything handled at the IOC including alarms
  • Its been done before
