Comment
Zero is not a DO but representative of the access to the
drive unit.
There may be an additional limitation through the
communication system (telegram length) or optional
scalability.
The four less significant bits are reserved for (future)
expansion of "No. of Elements" to 12 bits.
Limitation through compatibility with PROFIBUS process
data ASE telegram length.
