What causes KUKA Robot alarm KRC0766?

Attempting to index an array with a floating-point number instead of an integer. Using a multi-dimensional index on a single-dimensional array or vice versa. Array index value exceeds the declared array bounds or dimensions. Incorrect variable type passed as an array index (e.g., string instead of numeric). Mismatch between expected index type in function declaration and actual parameter passed.

How do I fix KUKA Robot alarm KRC0766?

1. Review the array declaration in the KRL program to verify its data type and dimensions 2. Check the index variable type being used to access the array and ensure it matches the expected INT type 3. Verify that array index values are within the valid range (0 to array size minus 1) 4. Inspect function calls that use array indexing to confirm parameter types are compatible 5. Use the KUKA IDE debugger to inspect array dimensions and index values at runtime 6. Correct the index variable type or array declaration to resolve the incompatibility

KUKA Robot KRC0766 - ARRAY INDEX NOT COMPATIBLE WITH INDEX 2102

This alarm indicates that an array index operation is being performed with an incompatible index type or value in the KRL program. The index used to access an array element does not match the expected data type or dimension requirements defined for that array.
