KUKA Robot KRC0913 - EXPRESSION NOT EQUAL TO INT 2250
This alarm occurs when a KRL expression or variable type does not match the expected INTEGER data type during program compilation or execution. The system expected an INT type value but encountered a different data type that cannot be implicitly converted.

KUKA Robot KRC0913 - EXPRESSION NOT EQUAL TO INT 2250
EXPRESSION NOT EQUAL TO INT 2250
This alarm occurs when a KRL expression or variable type does not match the expected INTEGER data type during program compilation or execution. The system expected an INT type value but encountered a different data type that cannot be implicitly converted.
Common Causes
- Assigning a REAL/FLOAT value to an INT variable without explicit casting
- Passing a non-integer type argument to a function that requires INT parameter
- Using a STRING or BOOL variable in a context requiring INT type
- Array indexing with non-integer expression or variable
- Incorrect data type in conditional statements or mathematical operations expecting INT
Troubleshooting Steps
- 1Locate the error line in the KRL source code referenced in the alarm message
- 2Verify the data type of all variables involved in the expression
- 3Add explicit type casting using INT() function to convert REAL to INT if needed
- 4Check function parameter declarations and ensure correct argument types are passed
- 5Review variable declarations to ensure they match their usage context
- 6Recompile the program after corrections and verify syntax in the KRL editor
