KUKA Robot KRC0889 - CONSTANT EXPECTED 1 2225

CONSTANT EXPECTED 1 2225

This alarm indicates a syntax error in KRL code where a constant value was expected but not found at the specified location. The compiler encountered an invalid token or missing constant declaration when parsing the program, preventing successful compilation of the <object name> module or function.

Common Causes

  • Missing or incorrect constant declaration in variable initialization
  • Invalid syntax in constant assignment (e.g., missing value after '=' operator)
  • Attempt to use a non-constant value where a constant is required
  • Typo or malformed number/string literal in constant definition
  • Missing or mismatched quotes in string constant declaration

Troubleshooting Steps

  1. 1Open the affected KRL source file in the KUKA IDE and navigate to the line indicated in the error message
  2. 2Verify that all CONST declarations have proper syntax: CONST <type> <name> = <value>
  3. 3Check that constant values are properly initialized and not left empty or incomplete
  4. 4Review the specific location around parameter @P1@ for missing operators, values, or delimiters
  5. 5Ensure string and numeric literals are correctly formatted with appropriate quotes and syntax
  6. 6Recompile the program after corrections and verify the alarm is resolved
