KUKA Robot KRC0981 - HIERARCH. NO. NOT IN SEARCH PATH 2318

HIERARCH. NO. NOT IN SEARCH PATH 2318

This alarm indicates that a hierarchical object or library file referenced in the KRL program cannot be found in the defined search path during compilation or program execution. The system searched through all configured library paths but failed to locate the specified object, preventing proper program linking or execution.

Common Causes

  • Referenced object file is not present in any configured search path directory
  • Search path configuration is incomplete or incorrectly defined in the project settings
  • Object filename or path contains typos or incorrect case sensitivity
  • Library or module was moved, deleted, or renamed without updating references
  • Search path directories have insufficient read permissions for the KUKA system user

Troubleshooting Steps

  1. 1Verify the object name and file path specified in the error message matches actual files on disk
  2. 2Check that all library search paths are correctly configured in the project properties and KRC settings
  3. 3Confirm the referenced file exists in one of the configured search path directories
  4. 4Review recent file system changes to ensure no objects were accidentally moved or deleted
  5. 5Clear and rebuild the project to refresh the object references and search path cache
  6. 6Verify file system permissions allow the KUKA robot controller user to read the library directories
