4-2        Automatically Configure a DeviceNet Network

 As you use AutoScan, keep the following in mind:

Use this tool to set the DeviceNet address of a device that has no 
switch, pushbutton, or other mechanism for its address.

If all your devices have a switch or pushbutton for their address, then 
skip this step. You do not need the Node Commissioning tool.

To install the Node Commissioning tool:

1. Get your RSLogix 5000 software CD.

2. On the CD, find the following folder:

\Tools\Node Commissioning Tool

where:

is the language of your software. For example, for 

software in English, open the ENU folder.

3. Follow the instructions in the readmefirst file.

1. AutoScan clears the current 

configuration.

With AutoScan, the scanner automatically sets up communication with the devices on your 
DeviceNet network. When you turn on the AutoScan option, the scanner removes any 
previous configuration that was done to the scanner.

2. AutoScan allocates a fixed memory 

size for each device.

At its default setting, AutoScan allocates 1 DINT of input memory and 1 DINT of output 
memory for each device on the DeviceNet network.

3. New devices are automatically 

available.

While the scanner is in idle mode, AutoScan continues to establish communication with 
devices that you connect to the network (as long as the device uses  

≤ 4 bytes of input data 

and 

≤ 4 bytes of output data).

4. The Automatic Device Recovery 

(ADR) option is not available.

To use the Automatic Device Recovery (ADR) option of a DeviceNet scanner, you have to 
use RSNetWorx software to edit the configuration of the scanner. This turns off AutoScan.

The actual data for the device fills the portion

that it needs and the rest remains unused.
