Hallo Emil,
currently the SD Card is required and is shipped together with the AXC F 2152.
This will properbly change however with the next FW Version.
Some functionblocks are compatible, others (like Interbus functions ect.) are not included yet.
Also many functionblocks have a changed behavior (but also have different names)
For Example:
Instead of "Datatype1_to_Datatype2" functionblocks (PCW 6.30) we now have "To_Datatype" Functionblocks wich cast any Datatype to a specific type.
We will supply however a library wich will add PCW6 functionalities & behavior and make Project migration from 6 to 7 easy.
So in this case you would have to import your PCW6 Project wich uses "Datatype1_to_Datatype2" by PLCopen to PC Worx Engineer.
-> add the migration Library (in there is a "Datatype1_to_Datatype2" that uses the new FW function "To_Datatype")
compile your project and go.
The migration library is currently a work in progress and will be released as soon as possible.
I wish you a merry Christmas,
Oliver
