KUKA Robot KRC0792 - FORMAL PARAMETER DECLARATION MISSING 2128

A formal parameter declaration is missing in a KRL program object (module or function). This occurs when a function or subroutine is called with parameters, but the corresponding parameter definitions are not declared in the function/module signature. The compiler cannot resolve the parameter passing mechanism without explicit formal parameter declarations.

FORMAL PARAMETER DECLARATION MISSING 2128

A formal parameter declaration is missing in a KRL program object (module or function). This occurs when a function or subroutine is called with parameters, but the corresponding parameter definitions are not declared in the function/module signature. The compiler cannot resolve the parameter passing mechanism without explicit formal parameter declarations.

Common Causes

  • Function called with parameters but no formal parameters declared in the function definition
  • Missing parameter list in function or subroutine declaration
  • Parameter name mismatch between function call and function definition
  • Incorrect syntax in parameter declaration (missing data type or parameter name)
  • Function definition copied without updating parameter declarations from original template

Troubleshooting Steps

  1. 1Identify the function or module name referenced in the alarm message from @P1@ placeholder
  2. 2Open the KRL source file containing the function definition
  3. 3Verify the function signature includes all required formal parameters with proper syntax (e.g., DECL INT parameter_name)
  4. 4Compare the function call parameters with the formal parameter declarations to ensure names and data types match
  5. 5Add missing formal parameter declarations to the function definition following KUKA KRL parameter syntax rules
  6. 6Recompile the program and verify the alarm is resolved
