KUKA Robot KRC0850 - BLOCK NUMBER EXPECTED 2186

BLOCK NUMBER EXPECTED 2186

This alarm occurs when the KRL compiler expects a block number statement but encounters different syntax or structure in the program. The compiler is unable to parse the expected block number format at the specified location in the source code.

Common Causes

  • Missing or malformed block number declaration (e.g., incorrect syntax like 'BLOCK 1' instead of proper block statement)
  • Incorrect indentation or line continuation that breaks the expected block structure
  • Using reserved keywords or invalid characters in block number definition
  • Block number statement placed in wrong program context or scope
  • Corrupted or incomplete source code file with missing block delimiters

Troubleshooting Steps

  1. 1Review the KRL source code around the error location and verify block number syntax matches KUKA KRL standards
  2. 2Check that block declarations use correct format and are properly positioned within the program structure
  3. 3Ensure proper line formatting, indentation, and that no special characters are corrupting the block statement
  4. 4Verify the program file is not corrupted by reloading or re-creating the source code
  5. 5Consult the KRL programming manual for correct block number declaration syntax and examples
  6. 6Recompile the program after corrections and verify the alarm clears
