Smart Transducers in Distributed and Model-Driven Control Applications: Empowering Seamless Internet of Things Integration

Abstract

Smart transducers based on ISO/IEC/IEEE 21450 provide standardized access to sensors and actuators. Hence, no centralized database is needed for the calibration and interpretation of the data collected by transducers. The smart transducer stores and maintains its individual transducer electronic data sheet (TEDS). Whenever transducers are replaced in an automation system, the correct description, calibration, and data stream interpretation come along with the newly connected transducer. The domain-specific modeling language defined by IEC 61499 improves the software development process for automation systems. However, it lacks a clear transducer interaction model.
