D
DF1 Protocol
A peer-to-peer link layer protocol that combines features of ANSI
X3.28-1976 specification subcategories D1 (data transparency) and F1
(two-way simultaneous transmission with embedded responses).
DF1 Rate
A unit of signaling speed equal to the number of discrete conditions or
signal events per second. It is also called “baud rate” or “serial port rate.”
DPI (Drive Peripheral Interface)
DPI is a second generation peripheral communication interface used by
various Allen-Bradley drives and power products, such as PowerFlex 70
and PowerFlex 700 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 “adapters” or “modules.” The
WIM 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 adapters. It can be run on computers running
various Microsoft Windows operating systems. DriveExplorer (version
3.xx or higher) can be used to configure the WIM and PowerFlex drives.

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 can be used to program, monitor, control,
troubleshoot, and maintain Allen-Bradley products. DriveTools SP
(version 1.01 or higher) can be used with PowerFlex drives. Information
