Glossary
A
Adapter
Devices such as drives, controllers, and computers usually require a
network communication adapter to provide a communication interface
between them and a network such as LonWorks. 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 20-COMM-L LonWorks adapter connects PowerFlex 7-Class drives to
a LonWorks network. Adapters are also called ‘cards’, ‘embedded
communication options’, ‘gateways’, ‘modules’, or ‘peripherals’.
B
Binding
A process whereby a network variable input and a network variable output
are connected together. Binding a network variable tells the device which
other devices it should talk to and what information it should share. Only
network variables of the same SNVT type can be bound together. For
example, a temperature type could not be bound to a pressure type.
Bus Off
A condition that occurs when an abnormal rate of errors is detected in a
device. The bus off device cannot receive or transmit messages on the
network. This condition is often caused by corruption of the network data
signals due to noise or data rate mismatch.
C
CAN (Controller Area Network)
CAN is a serial bus protocol on which DPI is based.
Channel
The transmission media that connect devices on the network such as twisted
pair 78 kbps or power line carrier. Also called segment.
Configuration Property
A data value used to configure the application program in a device.
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 Windows operating systems. You can obtain a
free copy of Connected Components Workbench softwa
.
ControlFLASH
A free software tool used to electronically update the 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.
