Glossary
The following terms and abbreviations are used throughout this manual. For
definitions of terms not listed here, refer to the Allen-Bradley Industrial
Automation Glossary, publicatio
.
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 network. 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 2100-ENET E3 Plus EtherNet/IP network adapter connects multiple
devices to an EtherNet/IP network. Adapters are sometimes also called cards,
embedded communication options, gateways, modules, and peripherals.
B
Bootstrap Protocol (BOOTP)
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 by using 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 accessed at
Bridge
A network device that can route messages from one network to another. A bridge
also refers to a communication module in a ControlLogix controller that
connects the controller to a network. See also Scanner.
C
Common Industrial Protocol (CIP)
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.
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.
