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.
