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-H adapter 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 3.xx or higher) can be used to configure
this adapter and PowerFlex drive. 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

Fault Action
A fault action determines how the adapter and connected drive act when a
communications fault (for example, a cable is disconnected) occurs.
Fault Configuration
When communications are disrupted (for example, a cable is disconnected),
the adapter and PowerFlex drive can respond with a user-defined fault
configuration. The user sets the data that is sent to the drive using specific
fault configuration parameters in the adapter. When a fault action parameter
is set to use the fault configuration data and a fault occurs, the data from
these parameters is sent as the Logic Command, Reference, and/or
Datalink(s).
Flash Update
The process of updating firmware in a device. The adapter can be flash
updated using various Allen-Bradley software tools. Refer to
Updating the Adapter on page 3-10
for more information.
