I think it has to do if you want to write the "Number of elements" (subindex 0) item or not together with your data or not.
In a lot of slaves the subindex 0 is not writable (or only writable in certain states) so I assume this adds the possibility to do a complete access writes for such slaves. It could also be useful if you want to read/write a whole struct without adding the number of elements item to the struct.
Thanks, that makes sense. I think our slave doesn't have a special "Number of Elements" at subindex 0, so it would make sense for me to read the whole thing as a struct.
