Chapter 4 Automatically Configure a DeviceNet Network
Implement AutoScan Make sure that the appropriate version of DeviceNet scanner is used to
implement this feature. You must use the CompactLogix 1769-SDN
DeviceNet scanner with firmware revision 4.1 or greater
This section describes how to set up the feature and how it operates. Notice
that explicit messaging is used for some of the steps. There are several ways
that an explicit message can be sent on DeviceNet.
• A user ladder program
• External programming/configuration devices, such as the 193-DNCT
terminal
• RSNetWorx for DeviceNet software
Since the purpose of the AutoScan feature is to eliminate the use of
RSNetWorx for DeviceNet, instructions on how to send an explicit message
via the class instance editor in RSNetWorx for DeviceNet are not covered in
this document.
1. Set up the physical network. Make sure all devices are addressed
appropriately, that is, there are no address conflicts, and are
communicating at the same baud rate.
The diagram below shows an example system using the 1769-SDN
scanner.
You can commission the node addresses via hardware switches on the
device(s) or through the 193-DNCT terminal.
