G-2 Glossary
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).

DPI (Drive Peripheral Interface)
DPI is a second generation peripheral communication interface used by
various Allen-Bradley drives and power products, such as PowerFlex
7-Class drives. It is a functional enhancement to SCANport.
DPI Peripheral
A device that provides an interface between DPI and a network or user.
Peripheral devices are also referred to as “modules” and “adapters.” The
1203-SSS converter and PowerFlex 7-Class HIMs (20-HIM-xxx) are
examples of DPI peripherals.
DPI Product
A device that uses the DPI communications interface to communicate
with one or more peripheral devices. For example, a motor drive such as
a PowerFlex 7-Class drive is a DPI product. In this manual, a DPI
product is also referred to as “drive” or “host.”
DriveExplorer Software
DriveExplorer software is a tool for monitoring and configuring
Allen-Bradley products and modules. It can be run on computers running
various Microsoft Windows operating systems. DriveExplorer (version
2.xx or higher) can be used to configure this module and connected
PowerFlex drives. Information about DriveExplorer software and a free
lite version can be accessed at http://www.ab.com/drives/driveexplorer.
DriveTools SP Software
A software suite designed for running on various Microsoft Windows
operating systems. This software suite provides a family of tools that you
can use to program, monitor, control, troubleshoot, and maintain Allen
