Alarm KRC1018

KUKA Robot KRC1018 - <object name> BLOCK TOO LONG OR INCORRECTLY COMPLETED 2703

This alarm indicates that a KRL program block (such as a function, module, or control structure) exceeds the maximum allowed length or contains incomplete/malformed syntax that prevents proper compilation. The KUKA interpreter cannot parse the block structure correctly due to size constraints or structural errors in the code.

KUKA Robot KRC1018 - <object name> BLOCK TOO LONG OR INCORRECTLY COMPLETED 2703

<object name> BLOCK TOO LONG OR INCORRECTLY COMPLETED 2703

This alarm indicates that a KRL program block (such as a function, module, or control structure) exceeds the maximum allowed length or contains incomplete/malformed syntax that prevents proper compilation. The KUKA interpreter cannot parse the block structure correctly due to size constraints or structural errors in the code.

Common Causes

  • Block (function/loop/conditional) exceeds maximum line count or character limit
  • Missing closing bracket, parenthesis, or END statement for a control structure
  • Improperly nested blocks or mismatched statement delimiters
  • Corrupted or incomplete KRL source file with truncated code segments
  • Excessively long single-line statements without proper line breaks or syntax errors in block declaration

Troubleshooting Steps

  1. 1Open the KRL source file in the KUKA IDE and locate the flagged block indicated in the error message
  2. 2Verify all opening brackets, parentheses, and block statements (IF/LOOP/WHILE/FUNCTION) have corresponding closing statements
  3. 3Break up excessively long blocks into smaller sub-functions or modular segments to stay within size limits
  4. 4Check for incomplete syntax such as missing semicolons, commas, or END keywords at block boundaries
  5. 5Recompile the KRL program after corrections and verify the syntax highlighting shows no errors
  6. 6If the issue persists, create a backup and reload the source file from version control or restore from a known working version
