J. Kissel, S. Dwyer As we resume power-outage recovery lock acquisition now that the environment is more suitable than it's been in a week (LHO:88473), we (as in DIAG_MAIN) found this morning the ASC_REFL_9_I analog whitening state (whose setting is managed by Beckhoff) didn't match the digital compensation (whose setting is managed by h1asc SDF system). We suspect that this is a symptom of yesterday's beckhoff == twincat computer reboots that were necessary to support the beckhoff chassis upgrades for JAC (LHO:88463). Not sure where/if these analog whitening settings are in the Beckhoff SDFs, but I've trended - H1:ASC-REFL_A_RF9_I1_SWSTAT digital compensation setting status - H1:ASC-REFL_A_RF9_WHITEN_SET_1 analog setting status and have now reset them to "normal," with 2 stages of whitening ON, and FM1 and FM2 compensating them.
