Data Rate
The speed at which data is transferred on the network. Each device on the
network must be set for the same data rate.
Datalinks
A Datalink is a type of pointer used by PowerFlex 7-Class drives to transfer
data to and from the controller. Datalinks enable specified parameters to be
read or written to without using explicit messages. The drive determines the
size of Datalinks.
DPI (Drive Peripheral Interface)
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 ‘adapters’ or ‘modules’. The
20-COMM-L 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 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
2.xx or later) can be used to configure this adapter and connected drive. This
software tool has been discontinued and is now available as freeware at
. 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, that you can use to program, monitor, control,
troubleshoot, and maintain Allen-Bradley products. DriveTools SP software
can be used with PowerFlex 750-Series, PowerFlex 7-Class, and PowerFlex
4-Class drives, and also legacy drives that implement a SCANport
communication interface. Information about DriveTools SP software can be
