How do you want to increment it? in what step size?

 Or you just want 30, 60 and then again 30 ,60 and so on? Could you be more precise in what you want?

The attached VI produces always values between 30 and 60

Let me know if you need explanation

It does not work. There is no decrementing.

p.s. This sounds like a howework problem and we do not provide questions to homework. Post what you have tried and explain where you are stuck. Do not use locals like the unworking example above.
