LonWorks network service (fieldbus) (LNS)
LonWorks Network Service (LNS) is the development platform of LonWorks, which serves as an interface for the adaptation of LON devices and LON services. From this development platform the LON network nodes can access all information concerning the Local Operating Network (LON).
In LonWorks, which is structured according to the OSI reference model, the database-supported LNS platform forms layer 3 with the network operating system.
The programming interfaces( API) for visualization, gateway functions and for further project planning tools are directly based on this layer, as are the various LON clients. The LON operating system includes tools for application and network management programming, test tools, manufacturer-specific programs for configuration and commissioning, and programs for communication via a wide variety of public and corporate networks.
