there is some pretty solid theory on how to translate between the kind of diagrams statebox uses and digital circuits. In fact we are doing some experiments with direct diagram to wafer (chip) translation using LibreSilicon http://libresilicon.com/
this is certainly not a done thing, but something we'd love to work more on in the future

It was possible since Simens Step 5 (since late 70s) to change your view between FBD/LAD and AWL. But AWL is just like Assembler, so .. yes. In old machines (we still have about 20 machines with Siemens S5) sometimes it's a must to use AWL.

Translate an IF statement you need to add jumps, so it's not really the same code.
Also for ex. the very simple Siemens LOGO controller has a simple software to program it. But if you use FBD, it's just possible to use a tag once. So if you need a tag multiple times, so you have to draw lines from the single tag. Even for super simple stuff it get's messy super quick.
