Glossary
Controller
A controller, also called programmable logic controller, is a solid-state control
system that has a user-programmable memory for storage of instructions to
implement specific functions such as I/O control, logic, timing, counting, report
generation, communication, arithmetic, and data file manipulation. A controller
consists of a central processor, input/output interface, and memory. See also
Scanner.
Data Rate
The speed at which data is transferred on the EtherNet/IP network. You can set
the adapter to a data rate of 10Mbps Full-Duplex, 10Mbps Half-Duplex,
100Mbps Full-Duplex, or 100Mbps Half-Duplex. If another device on the
network sets or auto-negotiates the data rate, you can set the adapter to
automatically detect the data rate.
Datalinks
A Datalink is a type of pointer used by PowerFlex 750-Series drives to transfer
data to and from the controller. Datalinks allow specified parameter values to be
accessed or changed without using explicit messages. When enabled, each 32-bit
Datalink in a PowerFlex 750-Series drive consumes 4 bytes in the input image
table and/or 4 bytes in the output image table of the controller.
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 6.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 (version 3.01 or later), that you can use to program, monitor, control,
troubleshoot, and maintain Allen-Bradley products. DriveTools SP software,
version 1.01 or later, 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
obtained at

Duplex
Duplex describes the mode of communication. ‘Full-duplex’ communications let
a device exchange data in both directions at the same time. ‘Half-duplex’
communications let a device exchange data only in one direction at a time. The
duplex used by the adapter depends on the type of duplex that other network
devices, such as switches, support.
EDS (Electronic Data Sheet) Files
Simple text files that are used by network configuration tools to describe
products so that you can easily commission them on a network. EDS files
describe a product device type and revision. EDS files for many Allen-Bradley
products can be found at
