producer/consumer network - On producer/consumer networks,
packets are identified by content rather than an explicit destination.
If a node needs the packet, it will accept the identifier and consume
the packet. The source therefore sends a packet once and all the
nodes consume the same packet if they need it. Data is produced
once, regardless of the number of consumers. Also, better
synchronization than Master-Slave networks is possible because
data arrives at each node at the same time

reference/feedback - Used to send a reference (for example,
speed, frequency, torque) to the product. It consists of one word of
input to the module from the network. The size of the word (either a
16-bit word or 32-bit word) is determined by the drive.

Feedback is used to monitor the speed of a product. It consists of
one word of output from the module to the network. The size of the
word (either a 16-bit word or 32-bit word) is determined by the drive.

RSNetWorx for DeviceNet - A software tool for configuring and
monitoring DeviceNet networks and connected devices. It is a 32-bit
Windows application that runs on Windows 95, Windows 98, and
Windows NT. Information about RSNetWorx for DeviceNet software
can be found at http://www.software.rockwell.com/rsnetworx.

scanner - A separate module (of a multi-module controller) or a
built-in component (of a single-module controller) that provides
communication with modules connected to a network.
