(domain resource usage message) that helps detect duplicate subnet/node IDs.
When the Monitoring & Control Example Application receives the DRUM, it
evaluates the subnet/node ID contained in the message. In the event that the
collision of subnet/node ID is detected, the example application reallocates a new
subnet/node ID and broadcast the new assigned subnet/node ID using the
DRUM. The IsiConfig class contains the implementation of the ISI
configuration.
IsiAppMsg Class
The IsiAppMsg class supports ISI messages. This class is derived from the
NiMsg class, which is the base class for all network interface messages. The
example application only uses the DRUM. The class can be modified to support
more ISI messages.
Network Management
This section describes the classes and files used for the network management
tasks performed by the Monitoring & Control Application.
AppImage Class
The Application Image module reads the application configuration, the SNVT
information, and fills in the NV Descriptor table with the SNVT data, the NV
direction, and the current connection information for each network variable
available on the device. This class also supports NV updates and NV polls.
NetMgmtMsg Class
The NetMgmtMsg class contains functions that support the following network
operations, both on the local network interface as well as on the remote device
(Neuron ID addressing):
• Query Status
• Update Domain
• Leave Domain
• Set Node Mode
• Ready Memory
• Wink
It also supports the following operations on the remote target only:
• Query Net Variable Config
• Query SNVT
• Update NV data
• Fetch NV data
