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 Communications Auxilliary
web interface, place one new DeviceNet module on the network at a
time. Refer to “New DeviceNet Module” in
Table 5 on page 29 .
–
If DIP or selector switches on hardware will be 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, refer
to the Rockwell Automation Literature Library at:

Set the Node Address Using the Hardware Mechanism
Many DeviceNet devices feature a hardware mechanism to set the network node
address (e.g., a rotary switch or a push wheel switch). Use the following procedure
to set the node address.
1.
Using Table 5 on page 29 as a guide, select a node address to apply to the
new device.
IMPORTANT
•
Unlike other online node commissioning tools, the Ethernet/IP
Communications Auxilliary Node Commissioning tool
cannot be
changed.
•
Ensure each device’s node address set by the hardware mechanism
matches the node address used in the DeviceNet network. Note that
if the network node address is set higher than 63, the Ethernet /IP
Communications Auxilliary Node Commissioning tool can be used
instead of the hardware mechanism.
IMPORTANT
In order for the node address change to take effect, cycle the module’s
power.
