Milestone 3 was successfully completed at the HHL in Leipzig as part of the PRODISYS project. Existing developments from the project that facilitate the use of an industrial cloud were demonstrated and the further procedure was discussed. Semantic integration of an administration shell, of self-notifying OPC UA plants, as well as the consolidation of secure information between different platforms and an automatic error detection system that includes maintenance requests were outlined. The aim for the final phase of the project is to consolidate the results and intensify development.
