IPO actuator and actuator sensors explained?

I’m working on a state transition and I want the specific frame number of a finished swing animation (This is a medieval RPG) in an IPO (Action!?) actuator to send a positive pulse to a acuator sensor that is tied to a state change. How can this be accomplished?
