What causes KUKA Robot alarm KRC0731?

Attempting to assign an enum constant from a different enum type to a variable. Using an undefined or incorrectly named enum constant in an assignment. Declaring an enum variable with one type but assigning constants from another enum definition. Misspelling the enum constant name, causing the compiler to fail type matching. Mixing enum constants across different enum type definitions without proper casting.

How do I fix KUKA Robot alarm KRC0731?

1. Verify that the enum constant name matches exactly with its definition, including correct spelling and case sensitivity 2. Check that the enum variable and enum constant belong to the same enumeration type definition 3. Review the enum type declarations in your KRL program to ensure consistency between variable declarations and constant assignments 4. Compare the data types in variable declarations with the enum types being assigned to identify mismatches 5. If enum constants must be converted between types, implement appropriate type casting or conversion logic 6. Recompile the KRL program after corrections and verify the syntax using the KUKA IDE or KRC compiler

Alarm KRC0731

KUKA Robot KRC0731 - ENUM CONSTANT TYPE DOES NOT MATCH ENUM VARIABLE 2067

This alarm occurs when a KRL program attempts to assign or use an enumeration constant that is incompatible with the declared enumeration variable type. The compiler detects a type mismatch between the enum constant being referenced and the enum variable it is being assigned to or compared with.
