Alarm 101110

Siemens 840D 101110 - Error on overall reset

Alarm 101110 indicates a critical error occurred during an overall reset (cold start) of the Siemens 840D control system. This typically points to corrupted system data, failed initialization of core components, or hardware communication failures that prevent the NCK (Numerical Control Kernel) from completing its startup sequence properly.

Safety

Refer to Siemens documentation
Ensure qualified technician performs repairs

Causes and Fixes

1
Power cycle the complete system (NCU and all drives) and attempt another overall reset (POWER ON + Reset simultaneously).
2
Boot from the commissioning/startup CF card or USB and check for system data integrity using the startup menu diagnostics.
Ensure you have current backups before proceeding with any restore operations.
3
Check battery voltage on NCU (should be >3.0V for lithium). Replace if below specification as this can cause SRAM data loss.
4
Restore NCK data from a known good backup using the archive/restore function from the commissioning tool or HMI service mode.
This will overwrite current configuration - verify backup integrity first.
