What does it mean when it says transfer function normalized

[Saaoclifford]

I am running my VI which is control system model. I have changed transfer function into a cluster of Numerator and Denominator and through a cluster unbudle into transfer function subVI. It does not show any fault until I run it and then it shows message "Transfer function normalized" what could be the problem. I will try and attach the vi. The Vi is created in GSim Tool set

This error is because the order of your numerator is higher than the order of the denominator of your transfer function. This is an impossible physical situation and leads to a delta function and its derivatives in the output response. Physically realizable systems must have the order of the denominator in the transfer function greater than the order of the numerator.
