KUKA Robot KRC1014 - RUNTIME DATA OF THE MAIN PROGRAM CANNOT BE USED 2351

RUNTIME DATA OF THE MAIN PROGRAM CANNOT BE USED 2351

This alarm indicates that the runtime data structure of the main program cannot be accessed or is corrupted, preventing the KRC controller from executing the program properly. The runtime environment fails to initialize or maintain the necessary data structures required for main program execution.

Common Causes

  • Main program file is corrupted or incomplete
  • Insufficient memory available for runtime data allocation
  • Incompatible KRL program syntax or structure in the main module
  • Missing or invalid program initialization declarations
  • Controller firmware version mismatch with compiled program

Troubleshooting Steps

  1. 1Verify the main program file exists and is not corrupted by checking the file integrity in the project directory
  2. 2Recompile the main program using KUKA.Workbench or KRC IDE to regenerate runtime data structures
  3. 3Check available controller memory and clear unnecessary files or data if memory is critically low
  4. 4Review the main program syntax for declaration errors, missing PROGRAM statement, or incompatible KRL commands
  5. 5Ensure the KRC controller firmware version is compatible with the compiled program version
  6. 6If issue persists, restore the main program from a known working backup or recreate it from source
