Control System Setup Help

Last year, our main programmer graduated. I have been given the job, and I have no idea how to set up the control system for programming. I remember last year we had to set up IP adresses and things of that nature, and I have no idea where to start. Any help would be appreciated. We are re-using the control system from last year, and I basically have a disassembled system with no instructions. Help.

Try following the control system manual here.
