“MESSAGE” EXPECTED 2199

This alarm indicates a syntax error in the KRL program where a MESSAGE statement was expected but not found or improperly formatted at the specified location. The parser encountered unexpected syntax that violated the expected MESSAGE command structure in the <object name> program element.

Common Causes

  • Incorrect nesting or scope of MESSAGE statement within program blocks

Troubleshooting Steps

  1. 1Open the affected KRL program file (<object name>) in the KUKA IDE or text editor
  2. 2Navigate to the line indicated by the error and verify MESSAGE statement syntax matches KRL documentation
  3. 3Ensure MESSAGE keyword is properly spelled and followed by required parameters in correct format
  4. 4Check for missing or extra parentheses, quotes, semicolons, or other delimiters around the MESSAGE statement
  5. 5Verify the MESSAGE statement is at the correct program scope and not incorrectly nested within other blocks
  6. 6Save the corrected program and recompile/reload to verify the syntax error is resolved
