KRC0866

KUKA Robot KRC0866 - “+” OR “” EXPECTED 2202

“+” OR “” EXPECTED 2202

This alarm indicates a syntax error in KRL program code where the compiler expected either a plus sign (+) or a closing brace/bracket (}) but encountered something else instead. The error occurs during program compilation at the point where an operator or delimiter was required but not found.

Common Causes

  • Missing or misplaced + operator in arithmetic or string concatenation expression
  • Missing closing brace } or bracket ) in a code block or function call
  • Incorrect syntax in variable declaration or assignment statement
  • Typo or incorrect character in place of expected operator or delimiter
  • Unmatched or improperly nested parentheses, braces, or brackets in the program

Troubleshooting Steps

  1. 1Review the KRL source code at the line number indicated in the alarm message for syntax errors
  2. 2Check for missing + operators in mathematical expressions or string concatenation operations
  3. 3Verify all opening braces {, parentheses (, and brackets [ have corresponding closing characters
  4. 4Look for typos or special characters that may have replaced the expected + or } operator
  5. 5Use the KUKA IDE syntax checker or compiler to identify the exact location of the syntax error
  6. 6Correct the syntax error and recompile the KRL program to clear the alarm
