Integration of ISO/IEC/IEEE 21450 Transducer Electronic Datasheets into OPC UA Information Model

摘要

Interoperability is one of the important characteristics of the cyber-physical system (CPS) based automation system. Engineers connecting field devices and control applications in an automation system regularly encounter interoperability problems. ISO/IEC/IEEE 21451 is a series of standard, which provide the building blocks to enable interoperability among field devices and control applications. transducer electronic datasheets (TEDS) are provided as a standard transducer description format by ISO/IEC/IEEE 21450. This format provisions the syntactic interoperability among heterogeneous field devices. However, open platform communication unified architecture (OPCUA) is a key enabling technology to achieve semantic and network interoperability. Therefore, the aim of this paper is to provide an integration approach for ISO/IEC/IEEE 21450 TEDS and devices in the OPCUA semantic model. We propose an ISO/IEC/IEEE 21450 based device integration concept with service oriented architecture.
