Replacing the 1769-ADN within a System
Same Series Replacement
When replacing an adapter with another adapter of the same series, you may need to use
RSNetWorx™ for DeviceNet software to change the minor firmware revision if the adapter’s
electronic keying option is set to Exact Match. If Exact Match keying is selected for the adapter
and the replacement adapter’s minor revision is different than the original adapter’s revision,
then the scanner’s ADR feature (if in use) will not be able to automatically configure the new
adapter.
For more information, refer to the Compact I/O 1769-ADN DeviceNet Adapter User Manual,

Different Series Replacement
To use a Series B adapter as a direct replacement for a Series A adapter, the following actions must
be taken:
•
It is recommended that you upgrade to RSNetWorx 4.01 (or later) to be able to take
advantage of the new features and capabilities of the Series B adapter, or to continue
using your older version of RSNetWorx (minimum of v2.23), install the alternate EDS
file
(1)
to enable it to recognize the Series B replacement (new features and capabilities are
not available until you upgrade).
•
The electronic keying options in your existing scanner and adapter configurations must
be set to Compatible (or equivalent).
•
If ADR is not configured or usable in your system, make sure that your existing adapters’
configurations are saved in RSNetWorx for DeviceNet software (*.dnt) data files.
If your application permits the use of ADR, changing the settings to Compatible should be done
at the earliest opportunity (i.e. prior to the need for replacement) to ensure that the ADR
function operates as expected when a Series B must be installed as a replacement for a Series A
adapter. If either the Series A adapter's or scanner’s electronic keying is set to Exact Match, the
scanner’s ADR feature does not automatically configure the replacement Series B adapter.

The alternate EDS file is required for versions of RSNetWorx for DeviceNet software prior to version 4.01. The standard EDS file available for the
Series B adapter is compatible only with version 4.01 (or later) of RSNetWorx for DeviceNet software. The alternate EDS file is available through the
Rockwell Automation Knowledge Base,
