The factory automation community is looking toward the Devices Profile for Web Services (DPWS) set of Web Service standards to provide a Service Orientated Architecture (SOA) enablement of factory elements. This paper examines the issues surrounding the application and future development of DPWS on production line machines and their integration with distributed enterprise applications. Issues raised reflect the need for more development on defining a generic approach to Web Service architecture in automation and the ontologies that support it. The concept of an automation lifecycle is introduced to aid this development from a more holistic perspective.
Service Oriented Architecture (SOA) based on Web Services is starting to be considered as the technology in the manufacturing environment that will enable an increase agile and collaborative manufacturing capabilities. This paper explores the application of SOA in shop floor automation using Device Profile for Web Services (DPWS) which allows SOA on a device. In this research, orchestration framework has been introduced to effectively control SOA services on devices. The orchestrator has been further implemented and demonstrated on a prototype production test rig. The functionalities and implementation of the orchestrator has been discussed in detail in this paper.
