DeviceNet Network: A DeviceNet Network is a producer/consumer Control Area
Network (CAN) that connects controllers (e.g., PLCs and SLCs) and devices (e.g.,
drives and motor starters). Both implicit (control I/O) and explicit (configuration)
messages can be transmitted over the network. A DeviceNet network can support a
maximum of 64 devices. Each device is assigned a unique node address and
transmits data on the network at the same data rate.
A cable is used to connect devices on the network. It contains both the signal and
power wires. Devices can be connected to the network with drop lines, in a daisy chain
connection, or a combination of the two.
General information about DeviceNet and the DeviceNet specification are maintained
by the Open DeviceNet Vendor’s Association (ODVA) at http://www.odva.org.
DeviceNet Manager Software: DeviceNet Manager software is a tool for configuring
and monitoring DeviceNet networks and connected devices. It is a 16-bit Windows
application that runs on Windows

95, Windows 98, and Windows NT
®
(4.0 or
greater).
DeviceNet Option Board: Devices such as drives, controllers, and computers usually
require an option board to provide a communication interface between them and a
network such as DeviceNet. A DeviceNet option board 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.
Option boards are sometimes also called adapters, cards, gateways, modules, or
peripherals.
