[Feature]: Maintained zenon releases (10, 11, 12, 14 and 15 at the time of writing) receive support for TIA Portal v21 projects. This enables variable import for projects created with TIA Portal v21 and communication with PLCs that execute a TIA21 project.  

To benefit from this fix:

• Update your zenon Software Platform to zenon 12 build 601779 or higher or a corresponding higher build number for versions zenon 10, 11, 14 or 15.
