How do I setup and OPC device to an AB Compactlogix V21 or later?  
I am running version 7.6.6  
When I create a new device I only have options for AB Compactlogix and Contrologix V20 or earlier.  
The manual states that there is anEthernet driver for V21and later yet I can not find it.

This driver didn’t exist until 7.7. You’ll have to upgrade Ignition or find some other way to connect (e.g. another OPC server).
