Nati

9、onal bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest

10、. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. IEEE Standards documents are developed within the IEEE Soc

11、ieties and the Standards Coordinating Committees of the IEEE Standards Association (IEEE-SA) Standards Board. The IEEE develops its standards through a consensus development process, approved by the American National Standards Institute, which brings together volunteers representing varied viewpoint

12、s and interests to achieve the final product. Volunteers are not necessarily members of the Institute and serve without compensation. While the IEEE administers the process and establishes rules to promote fairness in the consensus development process, the IEEE does not independently evaluate, test,

13、 or verify the accuracy of any of the information contained in its standards. The main task of ISO/IEC JTC 1 is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Sta

14、ndard requires approval by at least 75 % of the national bodies casting a vote. Attention is called to the possibility that implementation of this standard may require the use of subject matter covered by patent rights. By publication of this standard, no position is taken with respect to the existe

ISO/IEEE is not responsible for identifying essential patents or patent claims for which a license may be required, for conducting inquiries into the legal validity or scope of patents or patent claims or determining whether any licensing

This sta

29、ndard is intended to provide a basis for all future members of the IEEE 1451 family of standards that use digital interfaces. It should also be adopted by the existing members of the IEEE 1451 family of standards as they are revised in the future in order to provide the highest degree of compatibili

30、ty among the members of the family. This standard does not apply to IEEE Std 1451.4TM-2004, which only provides a size-constrained TEDS and an analog interface. The relationships between this standard and the other members of the family are shown in the following diagram. Three of these standards we

31、re complete before this standard was started and do not comply with this standard but will in the future as they are revised. They are IEEE Std 1451.1TM-1999, IEEE Std 1451.2 -1997, and IEEE Std 1451.3TM TM-2003. IEEE Std 1451.1 is an application that, in the future, will fit between the users netwo

32、rk and this standard. IEEE Std 1451.2 and IEEE Std 1451.3 will also be modified to interface with this standard. When these changes are made, the functions of an IEEE 1451 transducer will be as defined in this standard as will be the commands and TEDS. IEEE 1451.5TM-2007, which uses any of several d

33、ifferent wireless communications media, and IEEE P1451.6TMhave been written around the functions, commands, and TEDS as described in this standard. IEEE Std 1451.4 uses an analog signal interface and a TEDS that is not the same as that used by other members of the family. It may be used as the input

34、 to any of the other standards in the family but does not comply with the functions, commands, and TEDS defined in this standard. Items shown with a gray background are items that are not covered by any of the IEEE 1451 family of standards but that may be used. The underlying purpose of this family

35、of standards is to allow manufacturers to build elements of a system that are interoperable. To accomplish this goal, the IEEE 1451 family of standards divides the parts of a system into two general categories of devices. One is the network capable application processor (NCAP) that functions as a ga

36、teway between the users network and the transducer interface modules (TIMs). The NCAP is a processor-based device that has two interfaces. The physical interface to the users network is not specified in any of this family of standards. IEEE Std 1451.1 provides a logical object model for this ISO/IEC

37、/IEEE 21450:2010(E) IEEE 2007 All rights reserved xiinterface. Other applications may also be used at the manufacturers discretion. The communications interface between the NCAP and the TIMs is defined in the remaining members of the family of standards. Different manufacturers may build the NCAPs a

38、nd TIMs, and if both comply with this standard, they should be interoperable. This standard provides a description of the functions that are to be performed by a transducer interface module or TIM. Provisions are made for a high level of addressing that is independent of the physical medium-level an

39、d low-level protocols that are used to implement the communications. It defines the common characteristics for all devices that implement the transducer modules. The timing of the acquiring or processing of the data samples is described. Methods of grouping the outputs from multiple transducers with

40、in one TIM are defined. Common status words are also defined. A standard set of commands are defined to facilitate the setup and control of the transducer modules as well as to read and write the data used by the system. Commands are also provided for reading and writing the TEDS that supply the sys

41、tem with the operating characteristics that are needed to use the transducer modules. A method of adding manufacturer unique commands is included. In addition, this standard provides formats for the TEDS. Several TEDS are defined in the standard. Four of these TEDS are required, and the remaining TE

42、DS are optional. Some TEDS are provided to allow the user to define information and to store it in the TEDS. This standard provides areas that are “open to manufacturers.” It should be noted that any use of these areas may compromise the “plug-and-play” potential of controllers and TIMs. Notice to u
