The requirements on machine integration grew continuously over the last decades. Due to the variety of fieldbus standards and the complexity of a heterogeneous field device landscape this resulted in high implementation efforts for the application. This paper describes a conceptual framework for machine-to-supervisory communication done via protocol independent OPC UA objects integrating sercos and CIP based field device networks. It is based on an OPC UA server-client-network architecture via standard TCP/IP protocols. This approach allows interoperability between machine and supervisory systems and reduces the implementation time and costs.
