Alarm KRC0847

KUKA Robot KRC0847 - CONSTANT OR VARIABLE EXPECTED 2183

This alarm occurs during KRL program compilation when the parser encounters a syntax error expecting either a constant value or a variable declaration but finds invalid syntax instead. The compiler cannot proceed with program interpretation due to malformed syntax at the specified location in the source code.

KUKA Robot KRC0847 - CONSTANT OR VARIABLE EXPECTED 2183

CONSTANT OR VARIABLE EXPECTED 2183

This alarm occurs during KRL program compilation when the parser encounters a syntax error expecting either a constant value or a variable declaration but finds invalid syntax instead. The compiler cannot proceed with program interpretation due to malformed syntax at the specified location in the source code.

Common Causes

  • Missing variable declaration keyword (DECL, VAR, or CONST) before an identifier
  • Incorrect syntax in variable initialization or assignment statement
  • Using reserved keywords or invalid characters in variable/constant names
  • Missing or misplaced operators, brackets, or parentheses in expressions
  • Attempting to use undefined or improperly scoped objects in parameter declarations

Troubleshooting Steps

  1. 1Locate the exact line number in the KRL source file where error 2183 is reported
  2. 2Review the syntax around the error location for missing keywords (DECL, VAR, CONST) or invalid declarations
  3. 3Verify that all variable names follow KUKA naming conventions and do not use reserved keywords
  4. 4Check that all brackets, parentheses, and operators are properly matched and correctly positioned
  5. 5Compare the problematic code section with valid KRL syntax examples from KUKA documentation or working modules
  6. 6Recompile the program after corrections and verify no additional syntax errors appear in the compilation report
