Summary of notifications:
- Since around 14:41, ndscope has stopped rendering, frame data output has halted, and the GUARDIAN OVERVIEW screen has been showing a connection error for SYS_DAQ. A check via Web BIOS confirmed that the data concentrator is powered off. The cause remains unknown, and we are awaiting instructions from experts.
- During the 4 p.m. check, an issue was detected in the temperature monitoring. When we ran the script, an error occurred, preventing the data from being read. In the time series plot, several channels are missing data for approximately the last hour.
