This is my first time in using Profibus DP and also my first time in TIA Portal. I am not understanding where and how I go in the software to set up my Tags between the devices. Any suggestions or sample projects would be greatly appreciated.

There's lots of sensors on the market that have profibus but still don't have profinet. This is a good reason to add profibus master functionality to your controller. Profibus can travel long distances. It might be the cheapest way in many cases. This could be a good reason to add profibus device functionality.
