4-2 Configuring the Network
A LonMark profile defines the functional profile for a node
communicating with other nodes. The profile specifies which SNVTs
(Standard Network Variable Types) and SCPTs (Standard Configuration
Property Types) are used, and provides a semantic meaning about the
information being communicated.
When a profile is implemented in a node, it’s called a LonMark object.
One node can have several objects implemented. The LonWorks adapter
has two objects: a node object and a drive object. The node object
(
Figure 4.1 ) is used to control the other objects in a node.
Figure 4.1 Node Object
The drive object is based on a specific LonMark functional profile
(“Variable Speed Motor Drive: 6010”) and is shown in
Figure 4.2 .
