Abstract

Industrial cyber-physical systems provide a vision of collaborative industrial automation systems with maximized flexibility and interoperability. Service-oriented architecture is considered as the key to enabling collaboration in industrial cyber-physical systems. On the device level, software components are expected to act as services that can be published and accessed from other distributed nodes. In this paper, a plug-and-play service component approach is proposed based on web service description language (WSDL) and IEC 61499 function blocks. Those services are able to be discovered by adopting device profiles for web services (DPWS). Plug-and-play software services are demonstrated on a building automation system example and future works on automatic service orchestration are discussed.
