This standard is in
9、tended 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 compatibility among th
10、e 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 were complete
11、 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 1451.3 TMTM-2003. IEEE Std 1451.1 is an application that, in the future, will fit between the users network and this
12、 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 different w
13、ireless communications media, and IEEE P1451.6TM have 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 to any o
14、f 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 of standa
15、rds 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 gateway bet
16、ween 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 iv Copyright 200

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 and TIMs, and if both co
18、mply 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 and low-level protocols t
19、hat 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 within one TIM are defined.
20、 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 system with the operating
21、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 TEDS are optional. Some T
22、EDS 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 users Errata Errata, if
