SA0032: Unused enumeration constants

Detects enumeration constants which are not used in the compiled program code

Justification: Unused enumeration constants unnecessarily increase the size of the enumeration definition and can be confusing when reading the program.

PLCopen rule: CP24

Importance: Low

Tip

If multiple applications exist in a project, then only the objects below the currently active applications are affected. If there is only one application, then the objects in the common POU pool are also affected.

Example 42. Example
TYPE My_Enum :
(
    one := 1, 
    two := 2
);
END_TYPE
