Glossary
A
Adapter
Devices such as drives, controllers, and computers usually require a network
communication adapter to provide a communication interface between them and
a network such as EtherNet/IP. An adapter reads data on the network and
transmits it to the connected device. It also reads data in the device and transmits
it to the network.
The 20-COMM-ER EtherNet/IP adapter connects PowerFlex 7-Class drives and
SMC controllers to an EtherNet/IP network. Adapters are sometimes also called
‘cards’, ‘embedded communication options’, ‘gateways’, ‘modules’, or ‘peripherals’.
B
BOOTP (Bootstrap Protocol)
BOOTP lets the adapter configure itself dynamically at restart if the network has
a BOOTP server. The BOOTP server assigns the adapter a preconfigured IP
address, a subnet mask, and a gateway address; therefore, you do not have to
configure these with the parameters in the adapter. BOOTP can make it easier to
administer an Ethernet network. A free version of the Rockwell Software

BOOTP Server can be obtained at
Bridge
A network device that can route messages from one network to another. A bridge
also refers to a communications module in a ControlLogix controller that
connects the controller to a network. See also Scanner.
C
CIP (Common Industrial Protocol)
CIP is the transport and application layer protocol used for messaging over
EtherNet/IP, ControlNet, and DeviceNet networks. The protocol is used for
implicit messaging (real-time I/O) and explicit messaging (configuration, data
collection, and diagnostics).
Connected Components Workbench Software
The recommended tool for monitoring and configuring Allen-Bradley products
and network communication adapters. It can be used on computers running
various Microsoft Windows operating systems. You can obtain a free copy of
Connect Components Workbench software at

ControlFLASH
A free software tool used to electronically update firmware of Allen-Bradley
products and network communication adapters. ControlFLASH software is
downloaded automatically when the firmware revision file for the product being
