Alarm KRC0917

KUKA Robot KRC0917 - VARIABLE OR ARRAY ELEMENT EXPECTED 2254

This alarm occurs when the KRL compiler expects a variable or array element at a specific location in the code but encounters a different type of expression or syntax. The compiler cannot process the statement because the operand does not resolve to a valid variable or array element reference.

KUKA Robot KRC0917 - VARIABLE OR ARRAY ELEMENT EXPECTED 2254

VARIABLE OR ARRAY ELEMENT EXPECTED 2254

This alarm occurs when the KRL compiler expects a variable or array element at a specific location in the code but encounters a different type of expression or syntax. The compiler cannot process the statement because the operand does not resolve to a valid variable or array element reference.

Common Causes

  • Attempting to use a constant or literal value where a variable is required
  • Incorrect syntax when accessing array elements (missing brackets or wrong index notation)
  • Using a function call or expression result where a variable assignment is expected
  • Referencing an undefined or undeclared variable name
  • Attempting to modify a read-only or system parameter that cannot be assigned to

Troubleshooting Steps

  1. 1Review the KRL source code at the location indicated by the error message and verify the syntax
  2. 2Ensure all variables are properly declared before use with appropriate data types
  3. 3Check array access syntax is correct: use square brackets [index] for array element references
  4. 4Verify that the left-hand side of any assignment statement is a valid variable or array element
  5. 5Confirm that function names are not being used as variables and vice versa
  6. 6Recompile the program after corrections to verify the alarm is resolved
