Network management (NMT service)
All CANopen devices can be triggered via the network man
agement. A special identifier (000h) is reserved for that.
Commands can be sent to one or all servo controller via this
identifier. Each command consists of two bytes. The first byte
contains the command code and the second byte the node
address of the addressed servo controller. All nodes which
are in the network can be addressed via the node address
zero simultaneously. So it is possible, for example, to make a
reset in all devices at the same time. The servo controller
does not quit the NMT−commands. It is only indirectly poss
ible to decide if a reset was successful (e. g. through the
boot−up−message after a reset).
Structure of the message of the superimposed control:
Identifier

Meaning of the NMT codes:

Please note
The communication status has to be set for node guarding
and PDO communication as these features only work if the
communication status has been set to "operational".
