Abstract
This paper provides a technical overview of the smarttransducer interface module (STIM), the key element of the proposedIEEE-P1451.2 Draft Standard for Transducer to MicroprocessorCommunication Protocols and Transducer Electronic Data Sheets(TEDS) Formats. The draft standard was released for ballotingin August, 1996. Comments have been addressed and the draft wassubmitted to IEEE for recirculation to balloters in June, 1997.Objectives and genealogy of this standard are summarized. Keytechnical innovations such as the TEDS, representation of physicalunits, general calibration model, triggering of sensors and actuators,variable transfer rate between a host and the STIM, and supportfor multivariable transducers are briefly discussed. Detaileddescriptions of the STIM, TEDS, digital interface, and plug-and-playoperation are also provided. The specifics of physical unitsencoding, an example of a TEDS, and an example of the digitalinterface timing requirements are also included to aid the overview.This paper is an updated version of IEEE-P1451.2 Smart TransducerInterface Module, presented at Sensors Expo, Philadelphia, October,1996.
