1.2.1 Overview of DeviceNet

DeviceNet is a fieldbus network that provides easy interconnection between control
devices (PLC, PC, sensor, actuator, etc.).
DeviceNet was developed by Allen-Bradley as an open communication standard to
connect various field devices (sensor, actuator, Robot Controller, etc.). Because of the
open communication standard, DeviceNet users can easily construct a multi-vendor
system with various devices developed around the world.

1.2.2 Features of DeviceNet

Reduced Wiring
Compared with parallel wiring, DeviceNet employs a dedicated 5-wire cable (signal wires
and power wires) which substantially reduces the number of necessary wires, wiring time
and cost.
Detachable communication connectors provide you with simple wiring between nodes and
easy network separation or reconstruction.
Specified environment-resistance cables allow you to construct an environment-resistant
system at low cost.
Open Standard (Multi-vendor)
Due to an open communication standard, various devices from many manufacturers are
available.
reconstruction.
Maintenance spare parts stored on site (factory, etc.) can be reduced because different
manufacturers' devices can be used in case of a breakdown. Similar products are available
around the world due to a global standard DeviceNet.
