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.

ARRAY Module list: Entry of all slaves to
be managed, including guarding
values and the entry of actions to
be taken in event of guarding
errors.The array subindex corre

sponds to the Node-ID of the CAN-
open slave.

1F82h Request NMT ARRAY Remote control initiation of NMT
services. For example, tools can
use this to request intentional start/
stop of individual slaves. Remote
query of the current state.

ARRAY The values in this array define
whether the corresponding node
address (subindex) should be
restored during startup or not. If
the entry value is 0, the no restore
command should be sent to the
device.
