"hey actually i'm using LIN protocol in my project.i have some doubts.what is diagnostic message.where it is used..is NAD mandatory for undefined frame.."
- 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!
