Arduino Uno connection to Pc WorX

We are trying to use Pc WorX with Oscat network library to recieve and send information (X,Y coordinates), from the Arduino microcontroller. We are using the software on the arduino board.
The Arduino and the Pc are connected to each other by Phoenix Contacts FL Switch.
This is part of a school project trying to automate a labyrinth/maze game.

Any suggestions on how to establish a connection between the Arduino microcontroller and Pc WorX.
