Causes and Fixes

1
Verify update process status
Check HMI Advanced diagnostics screen or STARTER project tree to confirm active firmware transfer. Monitor progress bar if visible.
Firmware updates can take 5-45 minutes depending on component type and file size
2
Ensure stable power supply
Verify UPS backup is active and mains voltage is stable. Check parameter P0971 (power supply monitoring) shows no faults.
Never power down system during firmware flashing - this will corrupt the drive/NCU
