The answer you seek is documented here:
Translation: Step7 V17 and above is needed to make use of the firmware V4.5. But it is possible to use the firmware V4.5 PLC in an older Step7 version. Specify the highest firmware version that the Step7 configuration allows. The compiler will warn you that there is a mismatch. But the PLC will function as the firmware you specified in the program. As example: I have CPU1214 with firmware V4.6 specified as V4.3 in my Step7 V15.1 project. The CPU runs in a compatibility mode to respond as a firmware V4.3. That means my customer can still service his machine without needing to upgrade the software on his side. BUT he does not get the benefit of the security updates given by firmware V4.5. |
