Data integration is a key function in modern production environments. A multitude of data sources need to be accessed in order to extract, aggregate, evaluate, and present the right data to the right user at the right time. Service oriented solutions let expect benefits for this tasks, since they provide the loose coupling of applications and thus the requested flexibility for integration. The paper discusses advanced concepts by applying the SOA paradigm to a Function Block approach. The evaluation of the concepts has been performed within prototypes of the PLANTCockpit project.
