IEEE 1451.2-1997

This project will develop a standard digital interface for connecting transducers (defined here as sensors and actuators) to microprocessors. It will define a transducer electronic data sheet (TEDS) and its data formats. It will define an electrical interface, read and write logic functions to access the TEDS and transducers. This interface will be usable by a wide variety of sensors and actuators. This project will not specify signal conditioning, signal conversion, or how the TEDS data are used in application. There is currently no defined independent digital communication interface standard between transducers and microprocessors. Each vendor builds its own interface. Without an independent, openly defined interface, transducer interfacing and integration are time consuming and all vendors' duplicated efforts are economically unproductive. This interface will provide a minimum implementation subset which will allow self-identification and configuration of sensors and actuators and vendor extensibility to provide growth and product differentiation. New IEEE Standard - Inactive-Reserved. A digital interface for connecting transducers to microprocessors is defined. A TEDS and its data formats are described. An electrical interface, read and write logic functions to access the TEDS and a wide variety of transducers are defined. This standard does not specify signal conditioning, signal conversion, or how the TEDS data is used in applications.
