KUKA Robot KRC0924 - RIGHT OPERAND: ARRAY INVALID 2261
RIGHT OPERAND: ARRAY INVALID 2261
This alarm indicates that an array used as the right operand in an expression is invalid or improperly initialized. The array may be null, have incompatible dimensions, or contain data types that don't match the expected operation.
Common Causes
- Array variable declared but not initialized before use in expression
- Array dimension mismatch between source and destination operands
- Attempting to access array elements with incorrect index type or out-of-bounds indices
- Array passed as function parameter with incompatible data type or structure
- Dynamic array not properly allocated or resized before use in calculation
Troubleshooting Steps
- 1Review the KRL program line where alarm KRC0924 occurs and identify the array variable used as right operand
- 2Verify that the array is properly declared with correct dimensions and initialized with valid data before use
- 3Check array index ranges and ensure indices are within valid bounds (0 to dimension-1)
- 4Confirm that array data types match the expected types for the operation being performed
- 5If using dynamic arrays, ensure allocation and sizing operations completed successfully before array usage
- 6Use KUKA WorkVisual debugger to inspect array contents and structure at the point of failure
