&lt;p&gt;
- diagnostic messages are those frames in the protocol which
provide jobs such as changing of idententifier(ID), prtotected
identifier(PID), Auto addressing(NAD), assignment of new NAD and
other jobs... - you can use this message when to make your cluster
plug and play or resolve conflicts in new slave nodes so on and
soforth... - NAD is mandatory in the sence, if you have more than one
slave, you cannot difrentiate between them until you have a
respective NAD. It must be used based on your network design. You can
get away with it still!&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
