IEEE 21451-2 2010 Edition, January 1, 2010 A Smart Transducer Interface for Sensors and Actuators— Transducer to Microprocessor Communication Protocols and Transducer Electronic Data Sheet (TEDS) Formats
More info
Description / Abstract:
This standard defines a digital interface for connecting
transducers to microprocessors. It describes a TEDS and its data
formats. It defines an electrical interface. Read and write logic
functions to access the TEDS, and a wide variety of transducers.
This standard does not specify signal conditioning. Signal
conversion, or how the TEDS data is use in applications.
Purpose
There is currently no defined independent digital communication interface standard between transducers and microprocessors. Each vendor builds its own interface. Without and independent, openly defied interface, transducer interfacing and integration are time-consuming and duplicated efforts by vendors are economically unproductive. This interface provides a minimum implementation subset that allows self-identification and configuration of sensors and actuator, and also allows extensibility by vendors to provide growth and product differentiation.
