KUKA Robot KRC0808 - END OF CONTROL STRUCTURE NOT ALLOWED HERE 2144

END OF CONTROL STRUCTURE NOT ALLOWED HERE 2144

This alarm indicates a syntax error in the KRL program where a control structure termination statement (such as ENDIF, ENDWHILE, ENDFOR, or ENDSWITCH) appears in an invalid location within the code. The compiler detected an end-of-control-structure keyword that does not properly match an opening control structure statement.

Common Causes

  • Missing or mismatched opening control structure statement (IF, WHILE, FOR, SWITCH) before the END keyword
  • Incorrect nesting of control structures with improperly closed inner blocks
  • Duplicate END statements for a single control structure
  • END keyword placed outside of any active control structure block
  • Syntax error in the control structure declaration causing the compiler to lose track of structure boundaries

Troubleshooting Steps

  1. 1Open the KRL source file and locate the line number indicated in the error message
  2. 2Verify that every control structure termination statement (ENDIF, ENDWHILE, ENDFOR, ENDSWITCH) has a corresponding opening statement (IF, WHILE, FOR, SWITCH)
  3. 3Check the nesting hierarchy of control structures to ensure proper indentation and logical flow
  4. 4Remove any duplicate or orphaned END statements that do not match an open control structure
  5. 5Review the syntax of the control structure declaration for spelling errors or missing keywords
  6. 6Recompile the program after corrections to verify the syntax error is resolved
