NMT (Network Management Object)
The Network Management (NMT) follows a Master/Slave structure for executing NMT service. A
network has only one NMT master, and the other nodes are slaves. All CANopen nodes have a present
NMT state, and the NMT master can control the state of the slave nodes. Following shows the state
diagram of a node:
