A system is used with a computer-controlled machine having real-time electrical signals corresponding to the operation of a machine, for real-time data processing of electrical signals occurring within the machine. The machine includes a controller (112) and an event node, such as an actuator, sensor, or indicator (122), with an interconnect system disposed between the controller and the event node for exchanging data. The system includes an event data recorder (136) coupled to the interconnect system for selectively storing event data. The machine comprises an automotive vehicle. The event recorder need not be connected to the serial data output of the controller but is directly coupled to the real-time electrical signals occurring between the controller and its associated sensors and actuators. This allows for direct monitoring and diagnostics of the real-time system activity within the automotive vehicle, including intermittent problems which can be missed by or even caused by the controller. The event data recorder can be triggered (124) to store the data by a user input by pressing a push-button positioned on a wire-less transmitter that communicates with the event data (150) recorder. Feedback is provided to the user indicating that the event data recorder is storing the event data. |
