Alarm KRC0754

KUKA Robot KRC0754 - ’..’ EXPECTED 2090

This syntax error indicates that the KRL compiler expected a '.' (range operator) token but encountered something else during program parsing. The error occurs at line 2090 in the specified object, typically when defining array ranges, loop iterations, or other constructs that require the range operator syntax.

KUKA Robot KRC0754 - ’..’ EXPECTED 2090

’..’ EXPECTED 2090

This syntax error indicates that the KRL compiler expected a '.' (range operator) token but encountered something else during program parsing. The error occurs at line 2090 in the specified object, typically when defining array ranges, loop iterations, or other constructs that require the range operator syntax.

Common Causes

  • Missing or incorrectly placed '..' operator in array declaration or initialization
  • Incorrect syntax in FOR loop range specification (should be 'FOR i = start..end')
  • Malformed array index range in variable declaration or assignment
  • Using single '.' instead of '..' for range operations
  • Syntax error in parameter list where range operator was expected but not provided

Troubleshooting Steps

  1. 1Open the source file and navigate to line 2090 to identify the exact location of the syntax error
  2. 2Check all FOR loop constructs near line 2090 to ensure they use correct '..' syntax between start and end values
  3. 3Verify array declarations and range operations use double dots (..) not single dots (.)
  4. 4Review any recent edits to the program around the error line for missing or extra characters
  5. 5Compare the syntax against KUKA KRL documentation examples for proper range operator usage
  6. 6Correct the syntax error and recompile the program, then clear the alarm and restart the affected module
