Check NC program line

Navigate to Diagnostics > Alarms and note the %1 parameter value showing the specific function name. Locate this function in the active NC program.

Use the Program Editor search function (Ctrl+F) to quickly find the problematic function

Verify software version compatibility

Go to Commissioning > System data > Software versions and check current SINUMERIK version against function requirements in Siemens documentation.

Document current software version before any updates

Comment out or replace function

Temporarily comment the problematic line with semicolon (;) or replace with equivalent supported function to continue operation.

Keep original code commented for future reference when software is updated

Check installed options

Navigate to Commissioning > System data > Installed options and verify if required technology packages are listed and activated.

Compare with machine documentation to identify missing standard options

Verify license status

Go to Commissioning > System data > License information and check if technology-specific licenses are valid and not expired.

License changes may require system restart

Contact Siemens for licensing

If required option is missing, contact Siemens with machine serial number and required technology package information for license procurement.

Have machine data MD100 $MN_IDENT_TEXT ready for license requests

Check HMI software version

Navigate to Settings > System info and compare HMI version with NC kernel version for compatibility mismatches.

HMI and NC versions should typically match major release numbers

Update manufacturing cycles

Go to Program Manager > Cycles and check if newer cycle versions are available in the system or need to be loaded from Siemens.

Backup existing cycles before updating

Synchronize software components

Perform complete software update ensuring HMI, NC kernel, and cycle packages are all compatible versions.

Use Siemens SINUMERIK Operate software update function for synchronized updates

Check machine data configuration

Navigate to Commissioning > Machine data and search for MD parameters related to the specific function mentioned in alarm %1 parameter.

Use machine data filter function to search by function keywords

Verify PLC interface signals

Check Diagnostics > PLC > I/O status for required interface signals that enable the specific function on this machine configuration.

PLC modifications require safety system verification

Configure function parameters

Set appropriate machine data values and PLC interface signals according to machine manufacturer specifications for the required function.

Consult machine builder documentation for specific MD parameter values
