Chapter 2 Install a 1769 DeviceNet Communication Module
Set the Node Address of a 1769-ADN Module
The module supports DeviceNet node addresses 00...63. The factory default
setting is node address 63.
Set the node address by using the two rotary switches. Use a small, slotted
screwdriver to set the switches. The switch labeled MSD (Most Significant Digit)
sets the 10s while the switch labeled LSD (Least Significant Digit) sets the 1s.
Use the switches to select any network address from 00…63. Switch settings from
00…63 select node addresses 00…63. Switch settings from 64…99 instruct the
adapter to use the software programmed value for the network address.
Switch setting 95 is reserved for factory use in Series B adapters.
The software programmed value is set via the node commissioning tool available
in RSNetWorx for DeviceNet software and stored in nonvolatile memory on the
1769-ADN.

Use the removable, write-on label to mark your I.D. tag and other markings with
permanent ink. Your markings are visible when the module door is closed.
TIP
The baud rate for the adapter is set by way of the module’s Autobaud
feature at powerup.
TIP
Series B adapters that have their node address switches set to 95 start
up in a special factory mode that does not support I/O connections.
Series B adapters should not have their node address set to 95 for
normal use.
