After helping Aaron key the crate and do a burt restore, I realized that it would probably be best to record the steps that Koji showed me to do a burt restore as a reference for (anyone) the future
Commands (in terminal):
- burttoday: changes to the directory with snapshots for the day (/opt/rtcds/caltech/c1/burt/autoburt/today)
- burtgooey: opens a new window with several buttons of which "Restore" needs to be selected. This opens up a second window as shown in Attachment #1. Click on Snapshot files and navigate to the snapshot you wish to restore (these are present at /opt/rtcds/caltech/c1/burt/autoburt/snapshots) and select that. A green "OK" button indicates if the Restore can be performed without a hitch. Hit "Restore" to perform the burtrestore.
Also Gautam explained today that the sticky slider problem is a hardware issue. That it basically means that the signal (voltage output for instance) that you request from the medm screen is not what the hardware delivers. Twice now, we have got around that with a burtrestore. My understanding of a burt restore is that it is a restoration of values from a certain time to the EPICS channels. Therefore, I don't understand why a restoration at the software level should fix how the hardware responds? Why does this happen? |
