What causes KUKA Robot alarm KRC0920?

Attempting to assign a STRING, BOOL, or CHAR variable to an INT or REAL parameter. Using an incompatible data type in arithmetic operations or function arguments. Passing a wrong variable type to a function expecting INT or REAL parameters. Implicit type conversion failure due to conflicting data types in an expression. Array or structure element with incorrect data type being used in numeric context.

How do I fix KUKA Robot alarm KRC0920?

1. Locate the line number referenced in the alarm message and examine the operand in question 2. Verify the declared data type of the variable or parameter causing the type mismatch 3. Check function definitions and their parameter type requirements for the operation 4. Apply explicit type casting or conversion functions (INT(), REAL()) if intentional type conversion is needed 5. Review variable initialization to ensure correct data types are assigned from the start 6. Recompile the KRL program after corrections and verify the syntax is valid

Alarm KRC0920

KUKA Robot KRC0920 - OPERAND NOT EQUAL TO INT, REAL 2257

This alarm indicates a type mismatch error in KRL programming where an operand does not match the expected INT or REAL data type. The compiler or runtime environment encountered a value or variable at the specified location that cannot be converted to or does not conform to the required numeric data type for the operation being performed.
