1. A machinery health monitoring module that processes machine vibration data based on vibration signals and provides the machine vibration data to a distributed control system, the machinery health monitoring module comprising:

  • signal conditioning circuitry having an interface for receiving a plurality of analog vibration signals from a plurality of sensors attached to a machine, amplification and filter circuitry for conditioning the plurality of analog vibration signals, and analog-to-digital conversion circuitry for converting the plurality of analog vibration signals into a plurality of digital vibration signals;

    processing circuitry in electrical communication with the signal conditioning circuitry, the processing circuitry comprising a plurality of parallel digital signal processing channels, each channel for processing a corresponding one of the plurality of digital vibration signals to generate multiple scalar vibration values per channel and at least one vibration time waveform per channel; and

    logic generator circuitry in electrical communication with the processing circuitry, the logic generator circuitry operable to receive the multiple scalar vibration values and the at least one vibration time waveform, and operable to format at least the multiple scalar vibration values according to an input/output data protocol that is native to the distributed control system.
