# Convert direct driver nodes in imported applications

If the application you are importing contains any direct driver nodes, the import wizard will create one RSLinx topic for each direct driver node it finds. All topics are then converted into device shortcuts, to run with FactoryTalk Linx. You must have both RSLinx Classic and FactoryTalk Linx installed to make this two-step conversion.

To create topics after import, follow these steps in RSLinx Classic before importing the application.

## To validate direct driver nodes in RSLinx Classic

1. Create the appropriate RSLinx driver(s) if not already created (for example, AB_ETH-1).
2. If it is an Ethernet driver (AB_ETH-1), add the IP address of each Direct Driver Node to the Ethernet driver setup.
3. Start RSWho and select each device associated with each Direct Driver Node (e.g., 131.200.13.128)

If these steps are not done in this order, the topics generated by the import code will be invalid and will need to be fixed using the Topic Editor in RSLinx Classic.
