Development of smart transducers with IEEE 1451.4 standard for Industrial automation

A new IEEE 1451.4 standard for a smart transducer interface defines the concept for adding self-identification technology to traditional analog sensors and actuators. Numerous manufacturers´ offers 1451.4 sensors, which are often called TEDS sensors. Tools for the development of these sensors are not yet widely available. In this work, a tool for development of smart sensor fully compliant with the IEEE1451.4 standard is developed. Mixed-mode interface with auto detection of One-wire memory device has been developed by the use of Amicus Board which has PIC 18F25K20 microcontroller. To demonstrate the functionality and efficiency of developed tool, bridge sensor (load cell) is implemented and also analog temperature sensor is converted to smart transducer for Industrial automation. Details of sensor implementation and test results are presented. To validate, a smart transducer controller is made and tested.
