Publication 1790-IN012C-EN-P - January 2015

Install the Base Block

To install the base block:

set the node address on the base block.

mount the base block.

mount the optional expansion blocks.

wire the terminal block.

connect the DeviceNet cable.

Set the Node Address on the Base Block

When setting the node address on the base block, note that each base block comes with its 
internal program set for node address 63. To reset the node address, adjust the switches on 
the front of the base block. The two switches are most significant digit (MSD) and least 
significant digit (LSD). You can set switches to 00...63.

Node Address Example

The base block reads the rotary switches at power up only. Switch settings between 64 and 
99 cause the block to use the last valid node address stored internally.

You can also set the node address through RSNetWorx for DeviceNet software or a similar 
configuration tool.

When you use software configuration for the node address, set the switches to 64…99.

Example: Node 
Address is set at 11
