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 its PowerFlex 525 drive to an
EtherNet/IP network. Adapters are sometimes also called “cards,” “embedded
communication options,” “gateways,” “modules,” and “peripherals.”
ADC (Automatic Device Configura-
tion)
An RSLogix 5000 (version 20) and Logix Designer (version 21 or greater)
feature that supports the automatic download of configuration data upon the
Logix controller establishing an EtherNet/IP network connection to a
PowerFlex525 drive and its associated peripherals.
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 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 or CompactLogix
controller that connects the controller to a network. See also Scanner.
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.
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.
