What causes KUKA Robot alarm KRC0795?

Code statements written below a RETURN instruction in the same code block. Incomplete removal of code during program editing or refactoring. Misplaced RETURN instruction that was intended to be elsewhere. Missing or incorrect control flow structure (IF/ELSE/LOOP) around the RETURN. Copy-paste errors resulting in duplicate or orphaned code after RETURN.

How do I fix KUKA Robot alarm KRC0795?

1. Open the KRL source file and locate the line number indicated in the alarm message 2. Identify the RETURN instruction and review all code statements that appear after it 3. Delete or relocate any unreachable code that follows the RETURN instruction 4. Verify the program logic flow and ensure RETURN is placed at the intended exit point 5. If multiple exit points are needed, use conditional statements (IF/ELSE) to control when RETURN executes 6. Recompile the program to verify the syntax error is resolved

Alarm KRC0795

KUKA Robot KRC0795 - NOT ALLOWED EXPRESSION AFTER RETURN INSTRUCTION 2131

This alarm occurs when the KRL compiler detects code statements or expressions placed after a RETURN instruction within a function or subroutine. The RETURN instruction terminates execution and exits the program object, making any following code unreachable. This is a syntax error that prevents the program from compiling successfully.
