UNIGATE fieldbus gateway UNIGATE CL - LONWorks  V. 1.5

14.7.10

13.2.1

Implementing the network variables into the UNIGATE-LONWorks

A LONWorks-node is application-specific - which means that it is impossible to have one univer-
sal group of network variables for all kinds of different applications. For that reason the UNIG-
ATE-LON has to be pre-configured with a fixed group of network variables, that might be required 
for a certain kind of application.

13.2.2

Installation

The network variables can be connected with the nodes by means of an installation tool. This 
bonding connects the network variables between different nodes. As soon as the bonding is 
completed, the installation tool can be taken from the net. During the installation time every node 
receives a unique net identity. Fro more information on LONWorks please read LONWorks-tech-
nology data from Motorola or the LONWorks documentation from Echelon.

13.2.3
