Network Management Objects - HMS Anybus X-gateway CANopen Series User Manual

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.

- Defining whether the device is the
NMT Master
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.
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 Remote control start/stop of guard-
ing. Remote query of the current
state
ARRAY Expected device types for the
slaves
ARRAY Vendor identifications for the
slaves
Product codes for the slaves
ARRAY Revision numbers for the slaves
Expected serial numbers for the
slaves
VAR The maximum time between the
start of the boot process and the
signaling of succesful boot of all
mandatory NMT slaves. After this
time LSS services are initiated.
