Get the parent controller of a signal

scottMHA

I have an event handler (see below) that is raised when a signal's value changes. 

<div>private void Signal_Changed(object sender, SignalChangedEventArgs e)</div><div>&nbsp; &nbsp; &nbsp; &nbsp; {</div><div>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; Signal signal = sender as Signal;</div><div>&nbsp; &nbsp; &nbsp; &nbsp; }</div>

From the signal object (Signal signal) is there any way to get what controller/system that signals originated from? All im after is the name of the controller/system.
