Integrating KNX and OPC UA Information Model

Interoperability in all the levels of a communication architecture for automation applications cannot be easily satisfied because control devices are generally based on different technologies and communication protocols. This paper deals with the interoperability of a well-known communication standard for home and building automation, i.e. the KNX. Current literature presents several papers dem...

Standardized Smart Grid Semantics using OPC UA for Communication

As many roadmaps and studies were developed focusing on smart grid standardization a set of core standards was identified. Some of them specify own data models and thus, create a need for harmonization to enable interoperability in terms of communications. On the level of data model integration, two data models play key roles in the future smart grid. On the one hand the Common Information Mode...

Practical Security Recommendations for building OPC UA Applications

OPC UA - Service-oriented Architecture for Industrial Applications

OPC Unified Architecture (OPC UA) is the new standard of the OPC Foundation providing interoperability in process automation and beyond. By defining abstract services, OPC UA provides a service-oriented architecture (SOA) for industrial applications – from factory floor devices to enterprise applications. OPC UA integrates the different flavors of the former OPC specifications into a unified ad...

Semantic integration by means of a graphical OPC Unified Architecture (OPC-UA) information model designer for Manufacturing Execution Systems

Today, normally MES (Manufacturing execution systems) are isolated applications. Tomorrow, they have to be linked to each other. The prototypical engineeringframework based on OPC-UA (OLE for Process controlUnified architecture) processes data in the standardized XML-based format CAEX (Computer Aided Engineering Exchange) describing production plants. It configures MES and generates correspondi...
