As I understand your question, you were using RSLinx to control your Allen Bradley SLC 500 but you are now using the ControlLogix on ethernet instead. You are using LabVIEW DSC for your application development.
The first thing you will need to do is configure RSLinx for the ControlLogix device. The following <a href="http://zone.ni.com/devzone/conceptd.nsf/webmain/4c4ad8aea73ed2e586256a32007292fd?OpenDocument";>link</a> describes how to configure RSLinx. Once it is configured, you can launch Server Explorer, as described in the tutorial, to check the OPC connections. I hope this helps. If you have further questions, please post a reply.
