Abstract: The recently approved standard, IEEE1451.2 [IEEE], defines an interface between transducers and microprocessors useful in industrial automation and other fields. The standard defines a physical interface consisting of a data transport serial link, in addition to triggering, interrupt and hot swap signaling. The standard also defines a transducer electronic data sheet, TEDS, that describes the functionality of the transducer in machine-readable form. The interface supports as many as 255 independent transducer channels. These may be accessed individually or as a unit. This report describes the use of the correction and calibration features of this standard to implement a variety of measurement functions.
