Short story: I created a manual burt backup and burt restore script to back up the PLL and PDH common mode board settings in the EY Beckhoff system. You can find them in /ligo/home/controls/bram.slagmolen/burt/h2etcatey and are called h2ecateyBurtbackup and h2ecateyBurtrestore. They use a local autoBurt.req and safe.snap file.

Long story: Every time the beckhoff system in EY breaks all settings are losts, this greatly inconvience the the locking of the PLL and the PDH system.

Patrick T. generated an autoBurt.req file from Beckhoff system h2ecatey at EY with all the epics channels.

With help from Dave we created and place the autoBurt.req file in the target directory and created a safe.snap file in the burt/ direcotry (burtrb -f autoBurt.req -o safe.snap).

> controls@opsws5:burt 0$ pwd
> /opt/rtcds/lho/h2/target/h2ecatey/h2ecateyepics/
 

I edited the autoBurt.req file adding 'RO' infront of some channel names, this prevented some errors while creating the .snap file.

When trying to restore from the .snap file, not all settings are restored correctly. With some digging around, it seems that when we added and set '.ZNAM Off ' and '.ONAM On' to the variable names it seemed to work. In addition in the autoBurt.req file I added .VAL to the same channel names. I only did this to few required channels in the PLL and PDH CM path. After a burtrb the burtwb worked correctly.

This is seemed only required for the toggle swithces. Why this is required I don't know, although this doesn't happen with the QPD whitening channels. I think the OPC database may need some work.

When the Beckhoff system is rebooted all the .ZNAM and .ONAM addition are lost. I made a little script set_ZNAM_ONAM_records to add these again (not tested but should work).
