IEEE 1451.0-2024

This standard develops a set of common functionality and TEDS formats for the family of IEEE 1451 smart transducer interface standards. This functionality is independent of the physical communications media and includes the common network services and transducer services required to control and manage smart transducers and TEDS. It defines a set of implementation-independent APIs. This standard also defines universal unique identification, time synchronization, and security for the IEEE 1451 standards family. This project does not specify signal conditioning and conversion, physical media, or how the transducer data and TEDS data are used in applications.

Several standards in the IEEE 1451 family share certain characteristics, but no common set of network services, transducer services, and TEDS formats exists that facilitates interoperability among these standards. The purpose of this standard is to define a set of common network services, transducer services, and TEDS formats for IEEE 1451 smart transducers to achieve smart transducer interoperability and facilitate interoperability among the 1451 standards family. IEEE Std 1451.0-2007 has been revised to address the needs of new technologies, such as cyber-physical systems (CPS) and Internet of Things (IoT) for smart cities and smart grids.

Revision Standard - Active. The common functions, network services, transducer services, and Transducer Electronic Data Sheet (TEDS) formats for members of the IEEE 1451 family of standards to be interoperable in both network interface and transducer interface are provided. The common functions and characteristics that are to be performed by a network capable application processor (NCAP), which is a 1451 server, and all devices that implement the NCAP are defined. A set of network services that includes a set of commands and replies to access transducer data and TEDS data from the NCAP (1451 server) by the Internet of Things (IoT) applications (APPs) that are 1451 clients are also defined. Application programming interfaces (APIs) of network services are outlined to facilitate communications between the APPs (1451 clients) and NCAPs. Furthermore, the common functions and characteristics that are to be performed by a transducer interface module (TIM) and all devices that implement the TIM are discussed. A set of transducer services that includes a set of commands and replies to facilitate the setup and control of the TIM, as well as reading and writing the data used by the NCAP, are outlined. APIs of transducer services are also discussed to facilitate communications between the NCAPs and TIMs. Finally, the formats for a TEDS and methods to access the TEDS are specified, along with the common functions and characteristics that are to be performed by an APP and all devices that implement the APP.
