7.2.3 Network Management Objects
The NMT master controls the states of the connected network participants, the NMT slaves. It moni-
tors the devices and reports to the application, for example if an NMT slave fails. Please refer to the
CANopen specification, see “Related Documents” on page 1. In more complex systems several devices
are able to perform as master, which means that the configuration must have an entry defining which
device will act as master.
Once configured, the objects carry all information needed for the module to act on the network and the
application does not need to be accessed to obtain this information. This results in a substantial reduc-
tion of the overall implementation and maintenance effort when implementing multiple applications.
