5.4 Network management (NMT)
A CANopen network always needs a network management master. The NMT master
controls the NMT states of all connected nodes.
A node can be switched into three different states:
• Pre-Operational
• Operational
• Stopped
• After a CANopen node is switched on and the communication
and the internal application is initialised, the node switches
into pre-operational state. From this state the NMT-Master
can switch the node into the other states. To show that a
node is ready after boot up, it sends a "boot-up message".
These messages uses the CAN-ID of the Emergency service
(EMCY).
The message is permanently associated with the node ID.
