Knowledge-based web service integration for industrial automation

Web services are widely used for enterprise software development. Web service protocols simplify application integration thanks to interface description that can be processed at runtime and, in addition, due to mature and widely used standards for transportation and internetworking. Implementation of service-oriented architecture starts to get acceptance in the field of industrial automation ranging from international research project to the first implementations in industry including first commercial controller devices supporting web service communication protocols and executing deterministic control at the same time. The current research step is to allow knowledge-based integration of industrial automation systems and to exploit full potentials of run-time reconfiguration and adaptation of industrial systems. This paper demonstrates implementation of knowledge-based industrial system, the architecture and ontology model that can be generalized for implementation of other production systems.
