1-4 Overview of DeviceNet Stack Light

Publication 855T-UM001C-EN-P May 2005

The DeviceNet Stack Light connects to the DeviceNet Network using a cable with a micro

connector, a mini connector, or an open-style connector.

Typical DeviceNet Configuration

A DeviceNet Network supports multiple Stack Light devices and allows them to

communicate with other network devices (up to 64).

The DeviceNet Stack Light operates on the network as a slave device. It does not initiate

communications except for a duplicate node address check on power-up. The master writes

data to, and receives data back from, the DeviceNet Stack Light.

The following DeviceNet configuration shows a variety of products operating as slaves to a

PLC-5 controller with a 1771-SDN DeviceNet Scanner Module.
