Some Beckhoff SDF Channels Restored

Following the Beckhoff updates today (see alog88317), several settings needed to be restored in CS_ISC, EX_AUX, and EY_AUX after the initial SDF wrangling that was done after all the upgrades were finished.

As a reminder (for myself and others), when a Beckhoff computer is restarted, its settings are brought back up according to an internal settings file on that computer, NOT according to the safe.snap SDF table, unlike a traditional frontend model. This means the SDF tables for the restarted Beckhoff computers (basically anything with SYS in the name) will show several differences, that in most cases should be REVERTED. It's also useful to check the not monitored channels for differences, as we found a few of those today, although they were mostly just picomotor settings. See attached screenshots.
