Operating the Drive Using a
LonMark Profile
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 is 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 is used to control
the other objects in a node. See
Figure 4.1 .
Figure 4.1 Node Object
The drive object is based on a specific LonMark functional profile
(‘Variable Speed Motor Drive: 6010’), as shown in
Figure 4.2 .
