CIL Generator Error (CILG0004): There does not exist a matching data area for variable '...'.

The CIL Generator has detected the declaration of a located variable with an incorrect physical address in (the binary assembly of) a referenced C# library. The physical address is located in the controller memory. The declared address, however, does not match the actual data area declaration for the controller type used. (The term "data area" designates the available controller memory areas (system/shared/user memory).)
Possibly, the data area definition is also contained in the managed library code.

Remedy

Double-click the error message to jump to the affected variable.

Contact the provider of the library.

If the library source code is available and can be edited:

Correct the variable declaration by setting a correct memory address, or
correct the data area declaration.
Release the library again.
