Glossary - Allen-Bradley 22-COMM-E FRN 1.xxx User Manual

A
Adapter
Devices such as drives, controllers, and computers usually require an
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 22-COMM-E EtherNet/IP adapter connects PowerFlex Component
Class drives to an EtherNet/IP network. Adapters are sometimes also
called "cards," "embedded communication options," "gateways,"
"modules," and "peripherals."
B
BOOTP (Bootstrap Protocol)
BOOTP lets the adapter configure itself dynamically at boot time if the
network has a BOOTP server. The BOOTP server assigns the adapter a
pre-configured IP address, a subnet mask, and a gateway address;
therefore, you do not have to configure these using the parameters in the
adapter. BOOTP can make it easier to administer an EtherNet/IP
network. A free version of Rockwell Software's BOOTP Server can be
accessed at http://www.ab.com/networks.
Bridge
A bridge refers to a network device that can route messages from one
Ethernet 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).
ControlFLASH
ControlFLASH is an Allen-Bradley software tool that lets users
electronically update firmware on printed circuit boards. The tool takes
advantage of the growing use of flash memory (electronic erasable
chips) across industrial control products.
Controller
A controller, also called programmable logic controller, is a solid-state
control system that has a user-programmable memory for storage of
