Chapter 15 CANopen OverviewMS300 (High Speed Model)
15-4
 CANopen Communication Protocol
It has services as follows:
 NMT (Network Management Object)
 SDO (Service Data Objects)
 PDO (Process Data Object)
 EMCY (Emergency Object)
NMT (Network Management Object)
The Network Management (NMT) follows a Master/Slave structure for executing NMT service. Only
one NMT master is in a network, and other nodes are regarded as slaves. All CANopen nodes have
a present NMT state, and NMT master can control the state of the slave nodes. The state diagram
of a node is shown as follows:
