CIP (Common Industrial Protocol)
CIP is the transport and application layer protocol used by some scanners on
Remote I/O networks. The protocol is used for implicit messaging
(real-time I/O) and Block Transfer messaging (configuration, data
collection, and diagnostics).
Client/Server Network
This type of network has a server respond to client requests. For example,
the Remote I/O adapter is a server of data and responds to the requests of
client devices (for example, controllers).
Connected Components Workbench Software
The recommended tool for monitoring and configuring Allen-Bradley
products and network communication adapters. It can be used on computers
running various Microsoft operating systems. You can obtain a free copy of
Connect Components Workbench software at
ControlFLASH
A free software tool used to electronically update firmware of
Allen-Bradley products and network communication adapters.
ControlFLASH software is downloaded automatically when the firmware
revision file for the product being updated is downloaded from the
Allen-Bradley updates website to your computer.
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.
D
Datalinks
A Datalink is a type of pointer used by PowerFlex 7-Class drives to transfer
data to and from the controller. Datalinks allow specified parameters to be
read or written to without using explicit Block Transfer messages. When
enabled, each Datalink consumes either two 16-bit or two 32-bit words in
both the input and output image table of the controller. The drive determines
the size of Datalinks.
DPI (Drive Peripheral Interface)
A second generation peripheral communication interface used by various
Allen-Bradley drives and power products, such as PowerFlex 7-Class
drives. It is a functional enhancement to SCANport.
