Labview PID loop

[SK0480]

Iam working on a small project at school, and I need to use Labview to implement PID control...I know that this PID VI  comes with the control design and simulation toolkit..but unfortunately, the labview at my schools computer does not have a control toolkit...Can anyone please tell me how to make up VI for PID manually in LABVIEW..

Thanks

It is just math. Wikipedia has an excellent article on PID control. The block diagram of a PID controller looks a lot like what your VI will look like.
