P1451.4 - Standard for A Smart Transducer Interface for Sensors and Actuators--Mixed-Mode Communication Protocols and Transducer Electronic Data Sheet (TEDS) Formats

Project Details

This project establishes a standard that allows analog transducers to communicate digital information with an IEEE 1451 object. The standard defines a protocol and interface. It also defines a format of the Transducer Electronics Data Sheets (TEDS). The TEDS is based on the IEEE 1451.2 TEDS. The standard does not specify the transducer design, signal conditioning, or the specific use of the TEDS.

Active Projects	Active P1451.2 - ISO/IEC/IEEE Standard for Information Technology -- Smart Transducer Interface for Sensors and Actuators -- Part 2: Serial Point-to-Point Interface This standard defines serial interfaces between a transducer interface module (TIM) and a network module called network capable application processor (NCAP). It also defines a physical transducer electronic data sheet (PHY TEDS) which enables this standard to be in compliance with the IEEE 21450 standard. This standard does not specify signal conditioning or conversion.
Existing Standards	Inactive-Withdrawn IEEE 1451.3-2003 - IEEE Standard for a Smart Transducer Interface for Sensors and Actuators - Digital Communication and Transducer Electronic Data Sheet (TEDS) Formats for Distributed Multidrop Systems A digital interface for connecting multiple physically separated transducers to a single processor over a single pair of wires. The interface can support both asynchronous and isochronous data transfers. Several Transducer Electronic Data Sheets (TEDS) and their data formats are described. An electrical interface, channel identification protocols, time synchronization protocols, read and write logic functions to access the TEDS, and transducers with a wide variety of attributes are defined. This standard does not specify signal conditioning, signal conversion, or how an application uses the TEDS data.
	Active IEEE 1451.4-2004 - IEEE Standard for A Smart Transducer Interface for Sensors and Actuators--Mixed-Mode Communication Protocols and Transducer Electronic Data Sheet (TEDS) Formats This standard defines the protocol and interface that allows analog transducers to communicate digital information with an IEEE 1451 object. It also defines the format of the Transducer TEDS. The Transducer TEDS is based on the IEEE 1451.2(TM) TEDS. The standard does not specify the transducer design, signal conditioning, or the specific use of the TEDS.
