Glossary 149
Network
The DeviceNet network or the RSNetWorx for DeviceNet software
representation of the network.
Node
Hardware that is assigned a single address on the network. Also referred to as a
device.
Offline
When the host platform is not communicating on the network.
Online
When the host platform is configured and enabled to communicate on the
network.
Output Data
Data produced by the host platform that is written to the scanner module’s
memory. This data is sent by the scanner module to DeviceNet devices.
Point-to-Point
Used when describing a poll message. The message solicits a response from a
single, specified device on the network.
Polled
A type of input/output-data communication. A polled message solicits a
response from a single, specified device on the network (a point-to-point
transfer of data).
Record
The node address and channel-specific memory assigned in the scanner
module’s nonvolatile storage for a node in the scanlist.
