Note:
In PROFINET communication, the bits of each octet are sent the most significant
bit first. Therefore, the bits of every octet in the PROFINET message are in reversed
order compared to the bits shown in the figure. For example, the first bit that is sent
in the PROFINET message is the 7th bit of the first octet (I 0.7).
