KUKA Robot KRC0385 - <object name> ASSIGNED

<object name> ASSIGNED

This alarm indicates that an object or resource in the KRC controller cannot be processed because it is already assigned to another task, process, or entity. The controller has detected a conflict where the requested operation attempts to reassign an object that is currently in use or locked by another program or process.

Common Causes

  • Attempting to assign a tool, workpiece, or coordinate frame that is already in use by another running program
  • Multiple programs or tasks trying to claim ownership of the same object simultaneously
  • Incomplete deallocation of an object from a previous program execution
  • Conflicting object assignments in overlapping program calls or concurrent execution blocks
  • Workspace or resource management issue where an object remains assigned after program termination

Troubleshooting Steps

  1. 1Stop all running programs and check which tasks are currently utilizing the object in question
  2. 2Review the program logic to ensure objects are properly deallocated before reassignment attempts
  3. 3Verify that only one program instance is attempting to access the specific object at any given time
  4. 4Clear any orphaned object assignments by performing a controlled program reset or power cycle of the controller
  5. 5Check the KRC program sequence for conflicting assignments in PDEFINE, DEFDAT, or similar declaration statements
  6. 6Consult the KUKA programming documentation for proper object lifecycle management and use diagnostic tools to monitor active object assignments
