Getting Started
DeviceNet Networking Overview
Hitachi SJ100DN DeviceNet Series inverters are optimized for use on a DeviceNet
network. The inverter can respond to commands such as Run/Stop from a network host
device, for example. SJ100DN inverters can also drive a motor in stand-alone mode,
without a network connection. In that case, you use the inverter's keypad or input termi-
nals for Run/Stop commands. However, this addendum will use stand-alone operation
only for initial powerup tests of your SJ100DN inverter during installation. After the
installation material, the addendum covers network operation in detail.
The diagram below shows SJ100DN inverters connected to a DeviceNet network. Each
connection is called a node, and the SJ100DN connects to the network via the 5-pin,
color-coded Phoenix connector on the front panel as shown.

DeviceNet network
A DeviceNet network supports up to 64 devices, each with their own node address. One
device will be the network master; all other device(s) will be network slaves. The
SJ100DN inverter will operate as a network slave, as the network master (also called
host computer) will send commands to the slaves.
A factory network such as DeviceNet allows you to integrate devices of many different
types, even from various manufacturers, all into an integrated control system. A common
application that uses DeviceNet is a conveyor line. Typical devices on the network
include a PLC (programmable logic controller) or host computer (such as a PC), inverter
drives to run motors, proximity sensors, limit switches, diverter actuators, barcode
scanners, label printers, and other packaging or shipping devices. Note that Hitachi also
provides the L100DN DeviceNet Series inverters, which can also reside on the
DeviceNet network.

Monitoring" on page 39.
