Introduction
This manual is intended for qualified electrical personnel responsible for installing,
programming, and maintaining AC drives and LonWorks networks. It provides
information about the LonWorks

Communication Option Module (2LW3000) and
using it with VTAC 7

drives.
The LonWorks Communication Option module consists of a LonWorks module
mounted on an AnyBus

board. It is mounted in the VTAC 7 drive and receives its
required power from the drive and the network.
LonWorks networks consist of intelligent control devices, called nodes, that are
connected by one or more communications media and that communicate with each
other using a common protocol. A LonWorks network can consist of up to 32.385
nodes divided into 255 subnets (127 nodes/subnet).
Nodes on the network can be thought of as objects that respond to various inputs and
produce desired outputs. Linking the inputs and outputs of network objects enables
the network to perform applications. No central control or master-slave architecture is
required.
