Section 1: Setting Up and Using the i.LON 600 Internet Server

Introduction to the LONWORKS/IP Channel

Unlike traditional LONWORKS channels that use a dedicated physical wire, a

ONWORKS/IP channel uses a shared IP network, and is defined by a group of IP

addresses. These addresses form a “virtual” wire. i.LON 600s and PCs running LNS

(version 3.01 or better) use this virtual wire in the same way they use traditional

dedicated twisted pair wiring.

The concept is similar to a Virtual Private Network (VPN). Each i.LON 600 in the

system is aware of its peers and each i.LON 600 keeps peer information in its routing

tables so it can forward “tunneled” L

ONWORKS packets to the correct IP address. Figure

9 shows a typical channel configuration.

Because a virtual wire is created by the i.LON 600s, Figure 9 topology is logically the

same as Figure 10
