What causes KUKA Robot alarm KRC0767?

Array index variable contains a value greater than the array's declared size. Loop counter or index calculation produces an out-of-bounds value. Incorrect array dimension declaration that is smaller than required for the program logic. Off-by-one error in array indexing or loop conditions. Dynamic array sizing that fails to account for all required elements.

How do I fix KUKA Robot alarm KRC0767?

1. Review the array declaration in object @P1@ and verify the declared size matches the maximum index value used 2. Inspect all loops and index calculations that access the array to ensure they remain within bounds 3. Add boundary checking code before array access operations to validate index values 4. Check for off-by-one errors in loop conditions, particularly those using '<' versus '<=' operators 5. Enable KRL debugging mode and monitor variable values during program execution to identify when the index exceeds bounds 6. Increase the array declaration size if the program logic legitimately requires more elements, or refactor code to use appropriately sized arrays

Alarm KRC0767

KUKA Robot KRC0767 - ARRAY LIMIT EXCEEDED 2103

An array access operation attempted to read or write data beyond the declared array bounds in the KRL program object @P1@. This occurs when an array index value exceeds the maximum size of the array, causing a memory access violation. The system prevents the operation to protect program integrity and system stability.

2Inspect all loops and index calculations that access the array to ensure they remain within bounds
3Add boundary checking code before array access operations to validate index values
4Check for off-by-one errors in loop conditions, particularly those using '<' versus '<=' operators
