I am facing an issue with the Siemens WinCC supervisory system. I have two OS servers that were abruptly shut down and since then they are unable to read the files from the equipment, always reverting to a specific date before the supervisory system was shut down. I have tried most of the troubleshooting steps, including a reset of TagLogging and alarms, checking the folders and checking if the SQL service is running.

Does anyone have any additional suggestions that might help?

Hello,

Which version of WinCC are you using? Are there any errors in the program logs?

Good luck!
