Hello

in my model, I need to use a simple transfer function block : 1/(s+1). I am trying to control the coefficient of " s"  only,  to control the slope of the output curve. since I am running my model in real time windows target, that coefficient needs to be a variable that changes during the simulation based on the input provided from hardware input. so I can't manually enter it. 

anyone has any idea about that ? 

thanks a lot!!
