Rockwell Automation 22-COMM-L LonWorks Adapter - Manual (Page 65)

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 LonWorks. 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.
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
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.
D
Data Rate
The speed at which data is transferred on the network. Each device on a
network must be set for the same data rate.
DSI (Drive Serial Interface)
DSI is based on the Modbus RTU serial communication protocol and is
used by PowerFlex 4-Class drives.
DSI Peripheral
A device that provides an interface between DSI and a network or user.
Peripheral devices are also referred to as “adapters” and “modules.” The
