Development of an for Smar Anuradha C. Ranasinghe Department of Electrical & Computer Engineering Sri Lanka Institute of Information Technology anuradha.r@sliit.lk Abstract— The IEEE 1451 standard has enabl systems to achieve plug and play operation transducers, used in environmental and monitoring applications. The usual methodolog a Network Capable Application Process communicates with a Smart Transducer (STIM), which gives sensor readings to the en connection of the NCAP. This paper presents an intelligent, data acquisition device that inc NCAP and a universal interface which industrial analog transducers in 2, 3 or 4 wire in 1451.4 Mixed Model Interface (MMI). The is capable of identifying and configuring its smart transducers automatically according to Transducer Electronic Datasheet (TEDS) universal transducer interface is based hardware blocks present within the Cypress also function as the Network Capable Applicat Keywords—Reconfigurable Hardware, Interface, Smart Transducers, IEEE 1451.4, TE I. INTRODUCTION In the modern world, the combination o transducers and high speed networking provi to develop highly efficient control system applications. Depending on the situation, the deployed as individual units or could be distributed control system spanning over a distributed systems prove to be more flexible effective than traditional centralized systems variety of solutions and specifications of tran actuator) technologies available in the m problem of system integration with data acqu certain transducers cannot be linked due to se as hardware interface mismatch, and netwo This has a significant impact on several a system engineers, end-users and transducer difficulties to develop their products. Also, capabilities, each Data Acquisition device ha to a personal computer and separately a acquisition. With the development of the and the distributed systems, most engineerin deployed with hundreds of sensor nodes or large environmental structures.
