  1. My Task List Pam Gurd October 31, 2007

  2. Overview • HPRF IOCs • Cryo IOCs • Soft IOCs • Alarms • Other Shared stuff Title_date

  3. IOC Snapshot View of My Tasks Title_date

  4. HPRF IOCs (not including the Ring) • Location: $IOCTOP/linac/HPRF • All running 3.14.8.2 • Some planned updates to the PLCs might require database changes • Black heat changes • Write of timing pulse value • RF Leakage detector is being planned. Title_date

  5. NC HPRF IOCs • Talk to HVCM (modulator) and transmitter PLCs using etherIP • Timing, utility modules, etc. • RF Windows Title_date

  6. SC HPRF IOCs • Talk to HVCM (modulator) and transmitter PLCs using etherIP • Timing, utility modules, etc. • Beckhoff – Cooling, Bias power supplies • Tuning motors Title_date

  7. Cryo IOCs • Location: $IOCTOP/linac/cryo • Herb has already taken this over Title_date

  8. Cryo IOCs • Talk to PLCs via EtherIP • Also LVDTs and v460s for levels and temperatures • Lots of cpid records. Herb’s the expert on those. Title_date

  9. How to Find Soft IOCs • Server • Location (But if you’re looking for the location of the server, you’ll have to ask Greg or Sean.) Title_date

  10. Alarm Soft IOCs – $IOCTOP Part • Location: $IOCTOP/Alarms • Other systems – maybe system owners should take over. • ICS Stuff – IOC heartbeats (and a few PLCs), heartbeat delays and utility modules. • Herb will take over the cryo ones, he’s already worked on those. • These do the voice and summary, probably go with $SHARE soft_alh. • Maybe the HPRF ones go with the HPRF vxWorks IOCs. Title_date

  11. Notes about alarm soft IOCs • The shared part is in $SHARE/soft_alh. • Has scripts to build soft IOCs and templates for databases and edm scripts. • I’ll talk more about this later. • File structure and configuration syntax are explained in ????? Title_date

  12. IOC Heartbeat Alarms • The configuration files are ICS_IOC_HBt_Soft.xml ICS_IOC_HBt.xml ICS_RF_IOC_HBt.xml in /ade/epics/iocTop/R3.14.8.2/Alarms/ICS/<vers>/alarmCfgs where <vers> = R1-0-8b now. • Heartbeat alarms use the IOC access security setting to enable or disable the IOC heartbeat alarm. Title_date

  13. IOC Heartbeat Alarms, continued Click on the scroll icon to bring up the change screen. • The idea was that you should enter an elog entry when you changed the access security state. • Hidden behind this screen: • a sequence that waits for the “COMMIT” and sends the temporary values to the real values • Delphy’s script that sends a message to the elog – also on the “COMMIT”. Title_date

  14. IOC Heartbeat Alarms, continued again • You can send the same message to a group using the group function. (Click on the Group summary text square and then select IOCGroup.) • See instructions on the IOC Status Snapshot screen for more functions. Title_date

  15. Heartbeat Delays • Configured by a script that builds a heartbeat delay configuration file and a heartbeat delay substitution file database from an ordinary heartbeat soft alarm configuration file. • So, when you add an IOC to the heartbeat delay configuration file, you need also to rebuild the heartbeat delay soft IOC. • Heartbeat delays are automatically cleared upon IOC reboot. • But is this really useful? Title_date

  16. Heartbeat Delay Screen Title_date

  17. ICS Soft IOCs (other than soft alarms) Title_date

  18. PPS Bypass Status Changes • I haven’t seen this in use for a long time. Title_date

  19. IOC Groups • I don’t think anyone uses this but me. Title_date

  20. No IOC Left Behind • Location: $IOCTOP/SNS_softIOC/engScoreApp • It’s supposed to remind IOC engineers to clean up their IOCs, upgrade their systems, get rid of bad PV references, etc. • It’s associated with some cron jobs to run the accounting scripts (run and look at caSnooper, for example) and send an annoying message once a week. • Does anyone look at this? Title_date

  21. Cryo Soft IOCs Title_date

  22. Cryo_ICS:IOC_linux1 Location: $IOCTOP/Cryo_softIOC Manual valves. See CHL He Gas Storage screen CHL_GM_storage.edl. calc records for cryo displays Herb has done lots of this already. Title_date

  23. Manual Valve Screen Title_date

  24. Cryo_ICS:IOC_linux_pumpdown • Location: $IOCTOP/Cryo_softIOC • 2K Backfill, 2K pumpdown, cryo pumpdown, 2K trip sequences. • Sequences are explained on the edm screens used to control and display status. (Subatmospheric cold box on Cryo overview; choose Cryo conditioning; then Pumpdown; etc.) • The IOC name is too long for autosave. I will change it if I have a chance. • I guess Herb gets all of this. Title_date

  25. 2K Conditioning Title_date

  26. 2K Pumpdown Checklist Title_date

  27. 2K Backfill Title_date

  28. Cryo Pumpdown Title_date

  29. 2K Pumpdown Title_date

  30. Cryo_ICS:IOC_linux_heater • Location: $IOCTOP/Cryo_softIOC • Heater sequences. The heaters regulate the heat going into the 2K cold box, which works best if it doesn’t change too much. A pressure PID loop controls the total heat, and the heat to a cavity is adjusted based on the RF load in the cavity. • See SCL_heaterSeq_overview.edl • I guess Herb gets all of this. Title_date

  31. Cryo Heater Sequences Title_date

  32. Cryo_ICS:IOC_linux_jtoff • Location: $IOCTOP/Cryo_softIOC • JT Off sequences. Ask Herb what they do. • Herb gets this, too. Title_date

  33. JT Off Sequences Title_date

  34. HPRF Soft IOCs – Status Title_date

  35. Linac RF Status Title_date

  36. HPRF Soft IOCs – Power Limits Title_date

  37. Why all those soft IOCs? • It turns out if you have too many sequences running in one soft IOC, some of them don’t start properly. • I might have fixed this problem by putting delays in between starting sequences, but I never went back to retest it. • While I’m here, I’ll talk a little about name lengths. (autosave) • And beware tight loops in sequences, especially in soft IOCs. Title_date

  38. HPRF Soft IOCs Title_date

  39. Miscellaneous Other Soft IOCs Title_date

  40. FE_Ctl:IOC_linux_resume • Location: $IOCTOP/FE_softIOC • Front End Resume sequences • I created this because Alan Justice was too busy, maybe it should be his. Title_date

  41. ICS_Diag:IOC_linux_FBLM • Location: $IOCTOP/FBLMs • I created this for Andre Liyu, I don’t know anything about it. Or who might have taken it on. Title_date

  42. CF_TA:IOC_linux_hg_acc • Location: $IOCTOP/Tgt_softIOC • Mercury accumulation – ask Herb and Joe Devore about this one. Title_date

  43. CF_ST:IOC_linux1 • Location: $IOCTOP/CF_softIOC • Power Use Monitor – either Delphy (who created a similar soft IOC) or Marnelli could take this one. Title_date

  44. EPICS Shared Modules • vxStats • linuxStats • opStats • cpidRecord • lvdt • soft_alh Title_date
