  • Field device, system, and waveform data output method
    Patent number: 11226217
    Abstract: A field device includes a sensor configured to detect a physical quantity and to output the physical quantity as a sensor signal, a signal processor configured to process the sensor signal and to output the sensor signal as a processing result signal, a calculation processor configured to calculate output value data based on the processing result signal, an outputter configured to output the output value data to the outside, and a waveform acquirer configured to store waveform data of at least one signal among the sensor signal, the processing result signal, and a processing process signal that is a signal in a processing process in the signal processor, wherein the calculation processor is configured to acquire the waveform data from the waveform acquirer and to output the waveform data via the outputter.
