scaler error in CSS/Phoebus (Feb 2024 VM)

[lcgallington]

When I try to look at the scalers on the detectors tab in CSS (Feb 2024 VM), I get an error. Output from the error log and screenshots below.

To pin things down a bit, on the ioc_detectors page, the following items give an error:

1. scaler 1, scaler 2, and scaler 3 no matter how many channels are selected
2. SIS3820 (both options in dropdown)
3. quadEM: Quad Electrometer Ch.1, '' Ch. 2, '' Ch. 3, '' Ch. 4. '' MCAs [however vertival feedback and horizontal feedback options launch fine!) All other options launch without that popup message.

edit 1 to remove unintentional links to other issues.

edit 2: after more digging, it looks like the bob files for all these detectors are missing from the bob subdirectory, but there are opi files that correspond to these quantities in the opi subdirectory except for quadEM. If I stick the relevant opis in the bob directory, the error goes away.

Thanks for the report. Good news, the missing screens have been found and they are in your VM. Bad news, they are in the wrong directory!

~/epics_screens/synApps_6_2_1/adl/scaler16_full.bob
~/epics_screens/synApps_6_2_1/adl/scaler16_full_calc.bob
~/epics_screens/synApps_6_2_1/adl/scaler16_more.bob

~/epics_screens/synApps_6_2_1/adl/scaler16m_full_calc.bob
~/epics_screens/synApps_6_2_1/adl/scaler16m_more.bob

Use this bash command to move them to the correct place. You might need to restart phoebus (on my workstation, restart was not necessary).

mv ~/epics_screens/synApps_6_2_1/{adl,bob}/scaler16.bob
mv ~/epics_screens/synApps_6_2_1/{adl,bob}/scaler16_full.bob

Seems like that fixed the problem with the scalers. I checked the adl directory for the quadEM and SIS3820 bobs, but didn’t see them. I don’t think I need those for now though.

Found more .bob screens in the .../adl/ directory. This moves any and all of them:

mv ~/epics_screens/synApps_6_2_1/adl/*.bob ~/epics_screens/synApps_6_2_1/bob/
