DPI Peripheral

A device that provides an interface between DPI and a network or user.
Peripheral devices are also referred to as “adapters” or “modules.” The
20-COMM-K adapter, 1203-USB or 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

A tool for monitoring and configuring Allen-Bradley products and adapters.
It can be run on computers running various Microsoft Windows operating
systems. DriveExplorer (version 4.xx or higher) can be used to configure
this adapter and PowerFlex drives. Information about DriveExplorer
software and a free lite version can be accessed at

DriveTools SP Software

A software suite designed for running on various Microsoft Windows
operating systems. This software suite provides a family of tools, including
DriveExecutive, that you can use to program, monitor, control, troubleshoot,
and maintain Allen-Bradley products. DriveTools SP can be used with
PowerFlex drives. Information about DriveTools SP can be accessed at

EDS (Electronic Data Sheet) Files

Simple text files that are used by network configuration tools, such as
IXAAT CANopen Configuration Studio, to describe products so that you
can easily commission them on a network. EDS files describe a product
device type, revision, and configurable parameters. EDS files for many
Allen-Bradley products can be found at

Emergency Message (Emcy)

The emergency object is used in CANopen for sending fault information
from the communication adapter to the CANopen network. The emergency
object is triggered by a fault event from the drive or the communication
adapter itself. An emergency object is transmitted only once per error event.

Fault Action

A fault action determines how the adapter and connected drive act when a
communications fault (for example, a cable is disconnected) occurs or when
the controller is switched out of run mode. The former uses a
communications fault action, and the latter uses an idle fault action.
