NodeObject
The NodeObject (Object_ID: 0) is used in a L
ON
M
ARK
-compliant LON application to manage
other L
ON
M
ARK
objects present in the node. If implemented, it always receives the FB_ID:
0, i.e. it is the first object in the node. Only one such object may be present in each node.
In the application described here, only a minimal implementation of the functionality in
accordance with L
ON
M
ARK
has been made, i.e. the NodeObject is only used to test the
node's communication capability.
The status of a particular function block in the node is requested via
RQ_UPDATE_STATUS
. If the ID of the NodeObject is used in the request as the Object_ID,
the status of the entire node and of all the function blocks that are present is reported by
means of
nvoStatus
.
The relevant data for the LNS are displayed in the NodeObject area of the LNS Plug-In; this
cannot be parameterised.
