ioctsbdiag lost comms

Summary:
This Hall D IOC lost comms. The program is fully blocked because the viewers on the ioc also lost comms so the system can't confirm they aren't inserted.

Called for SL 2L13 SR temp CTD2L1362 rising. Tried opening up shield valve maximum from 78 to 95 but still continued rising. After further inspection, it looks like an issue with the TD. After contacting plant owner, will disable alarm, return shield valve max to 78, and will diagnose further in the morning.

Easier to communicate our main two hall D orbit lock configurations and less hassle in turning on 1 lock vs 4. Its now OpsMatrix13. I used the same PID gains and enabling expressions as the individual locks themselves.

Started plotting the 5C11B/AC lock inputs and outputs and noticed something was very wrong. Gains were set such that Integral G was -150 and 300 for X and Y, respectively, causing it to bounce between max + kick and max -kick constantly. Brought the gains down until it damped the harmonic content. Further optimization led to pretty good stability (see fig 2)

Looks like it was recalibrated on the 10th but has steadily declined since.
