What causes KUKA Robot alarm KRC0823?

Attempting to jump to a label defined in a different function or module. Label is located in a scope that is not accessible from the current code location. Jumping into or out of a loop structure (FOR, WHILE, REPEAT) is not allowed. Label does not exist or has been deleted but the JUMP statement still references it. Attempting to jump across interrupt handler or synchronized block boundaries.

How do I fix KUKA Robot alarm KRC0823?

1. Review the KRL source code and locate all JUMP and GOTO statements near line 2159 2. Verify that the target label exists and is defined in the same scope as the jump instruction 3. Ensure the label is not inside a restricted scope such as a function parameter block or interrupt handler 4. Check if the jump is attempting to cross loop boundaries or program structure limits 5. Refactor the code logic to avoid problematic jumps, using structured control flow (IF/ELSE, WHILE, FOR) instead 6. Recompile the program after making corrections and verify syntax with the KUKA KRC development environment

Alarm KRC0823

KUKA Robot KRC0823 - JUMP TO LABEL NOT ALLOWED 2159

This alarm indicates that a JUMP or GOTO statement in the KRL program is attempting to branch to a label that is not permitted in the current program context. The compiler or runtime environment has detected an invalid jump destination, typically due to scope violations or attempting to jump across program boundaries.
