Network Management
(NMT)
The device supports CANopen network
management functionality NMT Slave (Minimum
Boot Up).
Every CANopen device contains an
international Network Management server that
communicates with an external NMT master.
One device in a network, generally the host,
may act as the NMT master.
Through NMT messages, each CANopen device’s
network management server controls state
changes within its built-in Communication
State Machine.
This is independent from each node’s
operational state machine, which is device
dependant and described in Control State
Machine.
It is important to distinguish a CANopen
device’s operational state machine from its
Communication State Machine.
CANopen sensors and I/O modules, for example,
have completely different operational state
machines than servo drives. The “Communication
State Machine” in all CANopen devices, however,
is identical as specified by the DS301.
NMT messages have the highest priority. The 5
NMT messages that control the Communication
State Machine each contain 2 date bytes that
identify the node number and a command to that
node’s state machine.
Table 1 shows the 5 NMT messages surpported,
and Table 2 shows the correct message for
sending these messages.
NMT Message COB-ID Data Byte 1 Data Byte 2
Start Remote Node 0 01h Node-ID’
Stop Remote Node 0 02h Node-ID’
Pre-operational State 0 80h Node-ID’
Reset Node 0 81h Node-ID’
Reset Communication 0 82h Node-ID’
* Node-ID = Drive address (from 1 to 7Fh)
