Not sure if this is what your asking but AB has a program that will auto generate the ControlLogix tags from your DeviceNet network. It basically takes the info from the DeviceNet network and inserts the proper tags into the ControlLogix program you are using. Then you can use them as you need.
AB tech support should have the program for free. I belive it is called DeviceNet tag name generator. If not, I could probably send it to you
