What causes KUKA Robot alarm KRC0665?

Missing or incorrect DEF statement at the start of a function or program block. Incorrect block structure with executable code appearing before required declarations. Malformed declaration syntax with typos in keywords (e.g., 'DECL' instead of valid declaration). Missing END statement from previous block, causing parser to expect declarations in wrong location. Incorrect indentation or block nesting causing declaration context to be misinterpreted.

How do I fix KUKA Robot alarm KRC0665?

1. Review the KRL source code around the error line and verify all function definitions start with proper DEF statements 2. Ensure all variable and object declarations appear before any executable statements within their respective blocks 3. Check that block opening and closing statements (DEF/END, IF/ENDIF, FOR/ENDFOR) are properly matched and nested 4. Verify declaration syntax follows KRL standards: DECL, VAR, CONST, or appropriate object declarations 5. Use the KUKA IDE syntax checker or compiler to identify the exact line causing the declaration mismatch 6. If necessary, restructure the program block to place all declarations at the beginning before any logic statements

Alarm KRC0665

KUKA Robot KRC0665 - NEW BLOCK IS NOT A DECLARATION 2001

This alarm indicates that a new block in the KRL program does not contain a valid declaration statement as expected by the compiler. The parser encountered a block structure that violates KRL syntax rules requiring declarations at the beginning of program blocks or function scopes.
