A Standardized Approach for Transducer Interfacing: Implementing IEEE-P1451 Smart Transducer Interface Standards



Kang B. Lee, Richard D. Schneeman


NIST researchers have developed a reference implementation and companion demonstration for this currently defined set of specifications to provide a concrete example of the IEEE P1451, Draft Standard for a Smart Transducer Interface for Sensors and Actuators. The reference implementation includes both hardware and software components that when integrated together yield and environment for illustrating complete P1451 functional aspects and capabilities. This document briefly provides and overview of both parts of the standard and more specifically how they relate to this demonstration. The reference implementation approach used as well as resources required are also discussed to familiarize the reader with the demonstration environment. Specific implementation issues are then discussed concerning the several main areas of the software and hardware components used in this implementation. The first software component called NCAPTool, written in C++, provides a graphical user interface (GUI)-based Window environment in which various functional aspects of the standards can be exercised. The second component is a dynamic link library (DLL), also written in C++, that provides an Application Programming Interface (API) to the P1451.1, Draft Standard for a Network Capable Application Processor (NCAP) Information Model. The third component provides the hardware necessary to illustrate a tangible implementation of the P1451.2, Draft Standard for a Transducer to Microprocessor Communication Protocols and Transducer Electronic Data Sheet (TEDS) formats. All three components together illustrate the integration of both P1451.1 and P1451.2 as well as providing a visual capability for demonstrating the standards'' key functional aspects.
