Executive Summary

Today's field bus systems for connecting automation components in and between machines and units have a very high performance in regard to their transmission rate and realtime capability. Furthermore, they comprehend a multitude of functionalities like cross communication, safety protocols and automated address assignment. In addition, they define special logical views on the individual types of machines in terms of machine profiles. But these extensive functionalities make the configuration and programming of applications communicating via these field bus systems extremely complex. On top of the complexity in the communication of a single system there is a multitude of systems that are totally incompatible. Nevertheless, they hardly differ in most applications in regard to their range of functions and performance.
