Abstract
Analog transducers (sensors or actuators) are widely used in industry. The Institute of Electrical and Electronics Engineers (IEEE) 1451.4 standard defines a mixed-mode communication protocol and the Transducer Electronic Data Sheet (TEDS) formats for analog transducers. This standard enables the plug-and-play capability of analog transducers and easy integration of analog transducers with measurement and control systems. This paper describes a prototype of the IEEE 1451.4 one-wire interface for analog transducers. The prototype system developed at the National Institute of Standards and Technology (NIST) consists of an IEEE 1451.4-based transducer, a one-wire interface board, and a single board computer (SBC). An example of reading the IEEE 1451.4 TEDS from an IEEE 1451.4-compatible accelerometer is provided to illustrate system functionality.
