4.8.3
NMT protocol (node control)
The NMT protocol is used by the NMT Master to control the NMT state of remote nodes. Only the NMT
Master is allowed to produce this protocol.
The active NMT master ignores NMT messages with the Node ID 0 (all nodes).
4.8.4
NMT slave identification
The NMT start-up master and the LSS master are using the NMT slave identification data to identify the
NMT slave before configuring the NMT slave. If the configured identification data on the NMT master
and the response from the NMT slave are different, the NMT start-up master service will stop the start-
up of this NMT slave.
The sub-index corresponds to the NMT slave Node ID. The default value 0 means "not- configured"
and the NMT master will skip this entry. For the LSS Master, all NMT slave identification data need to
be configured. For the NMT Startup Master the NMT slave identification entries are optional.
