Semantic Error: A data type with the name '...' does already exist.
In the data types worksheet(s), two user-defined data types are declared with the same name.
As several data type worksheets are allowed in the 'Data Types' folder ('COMPONENTS | Programming > Local'), the definitions concerned may be located in different worksheets.
| Note
Uniqueness of user-defined data types: A user-defined data type must only be defined once in the data types worksheets of the project. An identical data type definition (same name) is, however, allowed in included libraries. This means when taking libraries into account, multiple definitions of the same data type are possible. |
