Glossary
Device-level Ring (DLR)
An Ethernet topology that consist of multiple devices configured in a circle-style
connection, implemented at the device level, and with no additional switches
required.
DHCP (Dynamic Host
Configuration Protocol)
DHCP lets the option module configure itself dynamically at restart if the
network has a DHCP server. The DHCP server assigns the option module a
preconfigured IP address, a subnet mask, and a gateway address; therefore, you do
not have to configure these using the parameters in the option module. DHCP
can make it easier to administer an Ethernet network. A free version of the
Rockwell Software BOOTP-DHCP Server can be accessed at
.
DriveExplorer Software
A tool for monitoring and configuring Allen-Bradley products and network
communication option modules. It can be run on computers running various
Microsoft Windows operating systems. DriveExplorer software, version 6.xx or
later, can be used to configure this option module 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
software, that you can use to program, monitor, control, troubleshoot, and
maintain Allen-Bradley products. DriveTools SP software can be used with
PowerFlex drives. Information about DriveTools SP software can be accessed at
Duplex
Duplex describes the mode of communication.
Full-duplex communication lets a
device exchange data in both directions at the same time.
Half-duplex
communication lets a device exchange data only in one direction at a time. The
duplex used by the option module 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
EtherNet/IP Network
EtherNet/IP (Industrial Protocol) is an open producer-consumer
communication network based on the Ethernet standard (IEEE 802.3), TCP/IP,
UDP/IP, and CIP. Designed for industrial communication, both I/O and
explicit messages can be transmitted over the network. Each device is assigned a
unique IP address and transmits data on the network. The number of devices that
an EtherNet/IP network can support depends on the class of IP address. For
example, a network with a Class C IP address can have 254 nodes.
General information about EtherNet/IP and the EtherNet/IP specification are
maintained by the Open DeviceNet Vendor’s Association (ODVA). ODVA is
