Beckhoff slow controls system is currently down, invalid alarms have been bypassed

Daniel, Dave:

h1ecatc1, the Beckhoff slow controls system, crashed at 15:38 this afternoon. The EDC is showing 35365 disconnected channels. The computer is completely unresponsive, including its management port. It will need a manual reset.

The alarms system restarted itself at this time. The ongoing HAM6 alarms remain bypassed, and in addition I have bypassed some invalid temperatures channels

Bypass will expire:
Tue Feb 20 03:49:26 AM PST 2024
For channel(s):
    H0:VAC-LX_Y0_PT110_MOD1_PRESS_TORR
    H0:VAC-LY_Y1_PT120B_PRESS_TORR
    H1:PEM-C_CER_RACK1_TEMPERATURE
    H1:PEM-C_MSR_RACK1_TEMPERATURE
    H1:PEM-C_MSR_RACK2_TEMPERATURE
    H1:PEM-C_SUP_RACK1_TEMPERATURE
