Service-oriented communication model for cyber-physical-production-systems

Abstract

The holistic use of Cyber-Physical-Production-Systems (CPPS) requires a new communication architecture, the classic automation pyramid hinders the service-orientation of this methodology. The different functionalities of the layers of the pyramid still have their authorization, while the communication needs a model, where all participants in a production deliver or consume information handled by services. In the Learning Factory of the Bochum University of Applied Sciences a research scenario is set up to investigate the CPPS-oriented communication in a production line between distributed PLCs, MES, ERP, Energy Monitoring and Cloud-Services. The developed communication architecture uses standards as OPC-UA to realize this service-orientation.
