101200

Navigate to Diagnostics > Safety > Safety Integrated Data in Siemens HMI or use NCK menu path: Param > Safety > SI Data Status to verify the copy operation timestamp and status indicators.

Check MD 30170 (SI_ENABLE) and MD 30171 (SI_COPY_MODE) parameters to confirm SI functionality is properly configured and the copy mode matches your maintenance requirements (online/offline).

Verify that Safety Integrated safeties (SLS, SOS, STO, etc.) respond correctly post-copy by executing a functional test via Diagnostics > Safety > SI Test Functions.

Clear the alarm acknowledgment from the alarm list; this is informational and requires no remedial action unless subsequent safety function failures occur.

Check control startup logs via Diagnostics > System Information > Startup Log to determine if 101200 appeared during normal boot sequence or post-update initialization.

Review SD 42500 (SI_COPY_AT_STARTUP) setting; if enabled, automatic SI data copying is expected and 101200 is a normal confirmation message.

Confirm no safety function errors appear in the active alarm list; cross-reference with MD 30180 (SI_VERSION) to ensure NCK and PLC SI versions are compatible.

Do not disable SI_COPY_AT_STARTUP without consulting machine safety documentation; this may compromise safety validation.

Identify which maintenance operation triggered the copy by reviewing Recent Events log (Diagnostics > Logs > Recent Events) and cross-correlating with parameter change timestamps in the audit trail.

If copy was user-initiated, verify the operation completion by confirming alarm 101200 appears only once; multiple occurrences may indicate retry logic due to validation failures—check alarm history for preceding error codes (100xxx range).

Re-run SI self-diagnostics via Diagnostics > Safety > Safety Integrated > Self Test to validate all safety functions (STO, SLS, SOS, Safe Motion Stop categories) are operational post-copy.
