Network management telegram for changing the communication phases
One node, the CAN master, changes the communication phases of the entire network. The
CAN master can also be a regenerative power supply module.
Example:
Data exchange via process data object is only possible in the "operational" state. If all
nodes connected to the bus are to be switched from the "pre-operational" to the
"operational" communication state by the CAN master, the identifier and the user data of
the transmit telegram have to be set as follows:
Identifier: 0x00 (network management)
User data: 0x0100 (NMT command "start remote node" to all nodes)
