A bit of SDF work today

This morning, I worked on adding a few more suspensions to be monitored by the SDF, mostly to add progress on my SDF learning curve.  While we continue to work through a path which monitors filter channels more efficiently, I went ahead and set the SDF to monitor every channel that the guardian doesn't touch for the MC1, MC2, and MC3 suspensions.

 

While I was at it, I decided to set the SDF to also monitor every LSC and LSCAUX channel.  I did not set any channels in these snap files to be ignored by SDF.  However, when I hit the LOAD TABLE ONLY button, I noticed that there are currently 9 unmonitored channels in the SDF LSC monitor.  See attached below.  Huh??  When I look at the h1lsc_safe.snap file, I confirm that the last column is all 1s, no zeros (therefore no ignoring any channels in this file).

So, the attached snapshot of the LSC SDF channels that are not being monitored is the same list as the SDF "NOT INIT" list.  Does this mean that the snap is old and there are new channels to be monitored?  These 9 channels (mostly associated with REFLAIR) are not in the burt request file (and therfore not in the safe.snap).  Possibly the alog below regarding new REFLAIR work will connect these channels in at some point...

If so, we'll have to reset the files with the appropriate 1s and 0s for the SDF to monitor after a new safe.snap is taken.

 

New update to this alog - I went ahead and started SDF monitoring on all ASC channels as well.  At least now, operators, etc can watch the lists change as guardian switches stuff if they want.
