What causes KUKA Robot alarm KRC0687?

Variable @P1@ is referenced in an IMPORT statement but does not exist in the target module's declaration list. Typo or case-sensitivity mismatch in the imported variable name between source and destination modules. The data list file (*.src or *.dat) was not updated after adding new module imports. Variable was deleted or renamed in the source module without updating the corresponding IMPORT declarations. Missing or incorrect module linkage in the project configuration.

How do I fix KUKA Robot alarm KRC0687?

1. Verify that the variable @P1@ exists and is properly declared in the target module's DEFDAT section 2. Check spelling and case sensitivity of the variable name in both the IMPORT statement and the DEFDAT declaration 3. Review the data list file to ensure all imported variables are listed with correct syntax 4. Confirm that the source module containing the variable is properly linked in the project structure 5. Recompile the entire project after correcting declarations to ensure consistency across all modules 6. If variable was recently renamed, update all IMPORT statements referencing the old name to use the new name
