What causes KUKA Robot alarm KRC0838?

Using relative file paths (e.g., './file.src') instead of absolute paths (e.g., '/KRC/Roboter/...'). Missing drive letter or root directory specifier in file path specification. Incorrect path syntax or missing leading slash in Unix-style path references. Environment variables or path aliases not properly defined or expanded. File reference in program lacks full qualification from system root directory.

How do I fix KUKA Robot alarm KRC0838?

1. Review the KRL source code line indicated in the error message for any file path references 2. Convert all relative paths to absolute paths starting from the appropriate KUKA system root directory 3. Verify the complete path syntax matches KUKA system conventions (e.g., /KRC/Roboter/Bin/ or C:\KRC\Roboter\Bin\) 4. Check that any environment variables or path aliases used are properly defined in the system configuration 5. Consult the KUKA directory structure documentation to ensure paths reference existing locations 6. Recompile the KRL program after correcting path references and verify the alarm clears

Alarm KRC0838

KUKA Robot KRC0838 - ABSOLUTE PATH EXPECTED 2174

This alarm occurs when a file path reference in KRL code is expected to be absolute (starting from root) but a relative path was provided instead. The system cannot resolve the relative path to an absolute location, preventing proper file access or module loading.
