device. The Device Manager uses the program ID to identify the

devices it discovers. Devices with the same program ID must have

identical external interfaces.

Subsystem

Devices, routers, and functional blocks are contained within

subsystems. With the LonMaker tool, each page in a Visio drawing

generally refers to a subsystem. Subsystems are useful for grouping

related devices. Subsystems may also be placed within other

subsystems, allowing the creation of a subsystem hierarchy for large

networks.

An LNS database can contain many subsystems. For example, a

network might consist of HVAC, lighting, and security subsystems.

These can be further divided into subsystems for each floor, and each

floor can be divided into subsystems for each room.
