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.
