LEGACY SYSTEMS’ SENSORS BECOME PLUG-N-PLAY WITH IEEE P1451.3 TEDSSinclair, Robert; Beech, Russell; Jones, Kevin; Mundon, Scott; Jones, Charles H.; NVE Corporation.; Edwards Air Force Base (International Foundation for Telemetering, 2002-10)Replacing and maintaining sensors in existing legacy systems is costly and time consuming since no information beyond voltage or current is supplied by these sensors. When a sensor is replaced or added, information for that sensor has to be incorporated by the software programmer into the main system software – a costly and time-consuming process. A method has been developed to give these old sensors the intelligence to meet the requirements of the proposed IEEE P1451.3 standard. This is accomplished with no changes to the legacy hardware and a minor, one time change to the legacy main system software.
