Glossary
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 embedded EtherNet/IP adapter connects PowerFlex 750-Series
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
preconfigured 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 network.
A free version of Rockwell Software’s BOOTP Server can be accessed

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).
ControlFLASH
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
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.
