Event Response

Event response applications require a response to a stimulus in a determined amount of time. An example is monitoring the temperature of an engine. When the temperature rises too high, the engine is slowed down. The event, in this case, is the temperature rising above a predetermined level, and the response is the engine slowing down. Another example comes from manufacturing. In a manufacturing line, a system senses when a part is in front of a station (the event) and takes a reading or manipulates the part (the response). If the system does not sense and respond to the presence of that part in a set amount of time, the manufacturing line creates defective parts.
