Glossary-3
DeviceNet Network
A DeviceNet network uses a producer/consumer Controller Area
Network (CAN) to connect devices (for example, controllers, drives, and
motor starters). Both I/O and explicit messages can be transmitted over
the network. A DeviceNet network can support a maximum of 64
devices. Each device is assigned a unique node address and transmits
data on the network at the same data rate.
A cable is used to connect devices on the network. It contains both the
signal and power wires. Devices can be connected to the network with
drop lines, in a daisy chain connection, or a combination of the two.
General information about DeviceNet and the DeviceNet specification
are maintained by the Open DeviceNet Vendor’s Association (ODVA).

DSI
Drive Serial Interface - a modification of the ModBus RS-485 serial
communication protocol used by various Allen-Bradley drives and
power products.
DSI Peripheral
A device that provides an interface between DSI and a network or user.
Peripheral devices are also referred to as “adapters” and “modules.” The
serial converter and PowerFlex 4-Class HIMs (22-HIM-*) are examples
of DSI peripherals.
DSI Product
A device that uses the DSI communications interface to communicate
with one or more peripheral devices. For example, a motor drive such as
a PowerFlex 4-Class drive is a DSI product. In this manual, a DSI
product is also referred to as “product” or “host.”
DriveExplorer Software
DriveExplorer software is a tool for monitoring and configuring
Allen-Bradley products and adapters. It can be run on computers running
Microsoft Windows 95, Windows 98, Windows NT (version 4.0 or
greater), and Windows CE (version 2.0 or greater) operating systems.
DriveExplorer (version 3.xx) can be used to configure this adapter and
PowerFlex 4-Class drives. Information about DriveExplorer software
and a free lite version can be accessed at http://www.ab.com/drives/
