The system encountered an error when attempting to create a log file. This can be caused by an excessive number of log files in the current directory (more than 99, Error code A) or by existing log files being too large (Error code B). This prevents the system from recording operational data or events, hindering diagnostics and traceability.
Click steps to track your progress.
Access the NCU or HMI file system (e.g., via network share or USB) and delete old, unneeded log files from the /sys/log directory.
Check the available storage space on the system drive or partition where log files are stored.
Reboot the NCU or industrial PC to clear any temporary file system locks.
Perform a file system check (e.g., chkdsk for Windows-based HMI, fsck for Linux-based NCU) on the relevant storage device.
Verify the permissions of the log directory to ensure the system user has full write access.
