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 ControlNet. An adapter reads data on the network and

transmits it to the connected drive. It also reads data in the drive and

transmits it to the network.

The 22-COMM-C ControlNet adapter connects PowerFlex 4-Class

drives to a ControlNet network. Adapters are sometimes also called

“cards,” “embedded communication options,” “gateways,” “modules,”

and “peripherals.”

B Bridge

A bridge refers to 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

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

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.

ControlNet

An open producer-consumer communication network with features such

as redundant media and deterministic I/O timing, designed for high

performance or time critical requirements.
