KUKA Robot KRC0720 - REAL CONSTANT EXPECTED 2056

REAL CONSTANT EXPECTED 2056

This alarm indicates that the KRL compiler expected a real (floating-point) constant value but encountered a different data type or invalid syntax at the specified location in the program. The compiler cannot proceed with program compilation until a valid real constant is provided where required.

Common Causes

  • Integer value provided instead of real constant (e.g., '5' instead of '5.0')
  • String or boolean value used where real constant is expected
  • Missing decimal point in floating-point number declaration
  • Invalid character or operator in constant expression
  • Variable name or undefined identifier used instead of literal real constant

Troubleshooting Steps

  1. 1Locate the error position in the KRL source file indicated by the compiler message
  2. 2Review the syntax around the flagged location and identify the expected real constant
  3. 3Verify the constant is formatted correctly with decimal notation (e.g., 3.14, 0.5, 10.0)
  4. 4Check that you are not attempting to use a variable or expression where a literal real constant is required
  5. 5Replace the incorrect value with a properly formatted real constant matching the required data type
  6. 6Recompile the program to verify the syntax error is resolved
