KUKA Robot KRC0857 - EXTENSION MISSING 2193

EXTENSION MISSING 2193

This alarm indicates that a required file extension or library component is missing from the KRL program or system configuration. The system cannot locate a necessary module, function, or object referenced in the code, preventing proper program execution or compilation.

Common Causes

  • Missing or deleted .src, .lib, or .h file that is referenced in the program
  • Incorrect file path or file name reference in the program code
  • Library or extension not installed or not properly loaded in the KRC system
  • Missing dependency files required by an external module or function call
  • File extension corruption or incomplete software installation

Troubleshooting Steps

  1. 1Check the KRL program source code for all file and library references, noting the exact names and paths
  2. 2Verify that all referenced .src, .lib, and .h files exist in the correct project directories on the teach pendant or controller
  3. 3Confirm the file extension is correct and matches the naming conventions expected by the KUKA system
  4. 4Reconstruct or restore the missing file from backup or original installation media if available
  5. 5Reload or reinstall the affected software package or library using the KUKA installation tools
  6. 6Restart the KRC controller and recompile the program to ensure all dependencies are properly recognized
