KUKA Robot KRC0833 - INVALID EXTENSION 2169

INVALID EXTENSION 2169

This alarm indicates that an invalid extension or file type was encountered during program compilation or execution, specifically related to error code 2169. The system rejected an attempt to use or reference an object with an unsupported or malformed extension that does not conform to KUKA KRL standards.

Common Causes

  • KRL source file has incorrect or unsupported file extension (not .src, .dat, or .h)
  • Attempt to include or reference a file with wrong extension in a program module
  • Corrupted or incomplete file extension in the project structure
  • Invalid characters or formatting in the file extension name
  • Mismatch between declared object type and actual file extension during compilation

Troubleshooting Steps

  1. 1Verify all KRL program files use correct extensions: .src for source files, .dat for data files, and .h for header files
  2. 2Check the file system and project tree for files with malformed or non-standard extensions
  3. 3Review include statements and external references to ensure they point to correctly named files with valid extensions
  4. 4Recompile the program after correcting file extensions and clear any cached compilation data
  5. 5Consult the program documentation and KUKA KRL coding standards to verify proper file naming conventions
  6. 6If using custom tools or batch processes, verify they are not inadvertently modifying file extensions during file operations
