What causes KUKA Robot alarm KRC0947?

CASE constant is declared as a different data type than the SWITCH expression (e.g., INT constant with REAL expression). Using string literals in CASE when SWITCH expression is numeric, or vice versa. CASE constant is an enum value incompatible with the SWITCH expression type. Type casting was removed or changed between the SWITCH expression and CASE constants. Incorrect variable reference in CASE clause that resolves to wrong data type.

How do I fix KUKA Robot alarm KRC0947?

1. Navigate to line 2284 in the KRL source file and locate the SWITCH statement 2. Verify the data type of the expression being evaluated in the SWITCH parentheses 3. Examine all CASE clause constants and ensure they match the SWITCH expression data type 4. Add explicit type casting to CASE constants if needed to match the SWITCH expression type 5. Check variable declarations used in both SWITCH expression and CASE constants for type consistency 6. Recompile the program after correcting the type mismatch to verify the error is resolved

KUKA Robot KRC0947 - CONSTANT TYPE INCOMPATIBLE WITH EXPR. TYPE IN SWITCH 2284

This is a KRL compiler error indicating a type mismatch in a SWITCH statement at line 2284. The constant value used in a CASE clause is incompatible with the expression type being evaluated in the SWITCH statement. The compiler cannot match the constant type to the switch expression type, preventing program compilation.
