5. Node Object functional block
The Node Object functional block includes 2 mandatory network variables “nviRequest (Object request)”
and “nvoStatus (object status)”. Upon receiving an update to the “nviRequest” network variable, the
request is processed and the “nvoStatus” network variable is updated with either the results of the
request, an in-process indication, or an error indication. The definition of the “nviRequest” network
variable includes an object ID field to allow the Node Object to report status and alarm conditions for a
device.
