initial condition CD step response

[KF_]

Hi,

I have a question about the initial conditions in the block CD step response. If I connect a second order transfer function model to the CD step response and I want to specify initial conditions, I can only specify one number otherwise I get an error. But a second order needs two initial conditions. Does this block still presume that the first derivate is zero, so I can only fill in the y(0) and not y'(0)? I attached a simple VI, you need control design and simulation toolkit though.

Best regards

Never mind, I just read this VI assumes initial conditions to be zero, a bit confusing however to give an option with initial conditions then :).
