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-R adapter, 1203-USB or 1203-SSS converter, and PowerFlex
7-Class HIMs (20-HIM-xx) are examples of DPI peripherals.
DPI Product
A device that uses the DPI communication 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 network
communication adapters. It can be used on computers running various
Microsoft Windows operating systems. DriveExplorer software, version
3.xx or later, can be used to configure this adapter and PowerFlex drives.
This software tool has been discontinued and is now available as freeware
. There are
no plans to provide future updates to this tool and the download is being
provided ‘as-is’ for users that lost their DriveExplorer CD, or need to
configure legacy products not supported by Connected Components
Workbench software.
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 software (version 3.01 or later), that you can use to
program, monitor, control, troubleshoot, and maintain Allen-Bradley
products. DriveTools SP software can be used with PowerFlex 7-Class and
PowerFlex 4-Class drives, and legacy drives that implement the SCANport
communication interface. Information about DriveTools SP software can be

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