You need Siemens STEP5, or IBH S5 for Windows.
Go online, upload from S5 PLC to PC.
Open the desired programs block in order to view them.
Switch to FBD view for display as block diagrams, which may or not be possible depending on if the code fits into FBD code.

Yes. You can upload from PLC to the PC. If you dont have the original source code, then there will be no comments or symbols of course.
