Check Program Compilation Messages

Navigate to HMI → Diagnostics → Alarms and review the complete alarm text to identify which strings were replaced (%1 to %2).

Verify Parameter Mapping

Access HMI → Commissioning → Machine → Setting Data and check if any machine data parameters have been automatically remapped.

Use MD11210 (COMPILE_MASK) to control compilation behavior and substitution warnings.

Update Program Syntax

Edit the NC program to use current SINUMERIK parameter syntax to prevent future automatic substitutions.

Always backup original programs before making syntax modifications.

Check Tool Management Settings

Navigate to HMI → Machine → Tool Management and verify tool parameter definitions match current SINUMERIK standards.

Review Tool Data Import

If importing tool data, check MD18118 (TOOL_MANAGEMENT_MASK) settings to control automatic parameter conversions.

Use TOOLMAN function to validate tool parameter consistency after imports.

Update Tool Parameter References

Modify tool calls in NC programs to use current parameter syntax (e.g., $TC_DP1[T,D] instead of legacy formats).

Check Machine Data Configuration

Access HMI → Commissioning → Machine → Machine Data and review recently modified parameters for automatic conversions.

Verify MD Number Mapping

Use SINUMERIK documentation to confirm deprecated MD numbers have been properly mapped to current equivalents.

Enable MD11200 bit 0 to log all machine data access and modifications.

Update Configuration Files

Modify INI files and configuration scripts to use current MD numbers and eliminate automatic substitutions.

Review Variable Declarations

Check DEF statements and variable declarations in NC programs for naming conflicts or deprecated syntax.

Verify R-Parameter Usage

Examine R-parameter assignments and ensure they follow current SINUMERIK naming conventions and scope rules.

Use local variables (LUD) instead of global R-parameters when possible to avoid naming conflicts.

Update Variable References

Modify program code to use explicit variable names that match SINUMERIK standards and avoid automatic substitutions.

Check Cycle Definitions

Navigate to HMI → Program Manager → Cycles and verify cycle parameter definitions match program calls.

Review Cycle Call Syntax

Examine cycle calls in NC programs for deprecated parameter names or calling conventions.

Use F1 help in cycle dialogs to view current parameter syntax and requirements.

Update Cycle Parameters

Modify cycle calls to use current parameter names and eliminate automatic substitutions during execution.
