Chapter 4 Add Devices to the DeviceNet Network
Node Address Basics
• Verify the node address assigned to the new device.
• Prevent duplicate node address assignments.
– When connecting new DeviceNet modules with the Node
Commissioning tool from the EtherNet/IP communication auxiliary
module web interface, place one new DeviceNet module on the
network at a time. See “New DeviceNet Module” in Table 5 on
page 39 .
– If DIP or selector switches on hardware are used, set the network
node address for the device before connecting it to the network.
• Leave node address 63 open.
For more information about setting the node address for DeviceNet devices,
See the Rockwell Automation Literature Library at: http://

Set the Node Address
Using the Hardware Mechanism
Many DeviceNet devices feature a hardware mechanism to set the network
node address (for example, a rotary switch or a push wheel switch). Use the
following procedure to set the node address.
1. Using Table 5 on page 39 as a guide, select a node address to apply to the
new device.
IMPORTANT Ensure that the node address of each device set by the hardware mechanism
matches the node address used in the DeviceNet network. If the network
node address is set higher than 63, you can use the Ethernet /IP
Communication Auxiliary Node Commissioning tool instead of the hardware
mechanism.
IMPORTANT For the node address change to take effect, cycle the power to the module.
