Profinet is developing into the best performing Ethernet system in industrial automation systems.
The consistent use of Ethernet in automation systems helps cut costs in the planning, commissioning and maintenance of networked automation systems in the machinery and equipment building industry.
This led PI (Profibus and Profinet International) to pursue the development of Profinet.
Within the framework of the project titled "Real-time Ethernet in sensor/actor networking" supported by the German Federal Ministry of Education and Research, the potential of today's real-time Ethernet systems was analysed by the Institute Industrial IT of the University of Applied Science of Lippe and Hoxter.
The project revealed that the underlying individual frame setup of Profinet offers the biggest performance potential in real machine and plant structures.
Profinet can be used also in the field of simple sensor/actor networking with a pure line topology and its typically small data volumes per subscriber.
Profinet is developing into the best performing Ethernet system in industrial automation systems.
In addition, the project has revealed that Profinet profits from the Ethernet evolution (such as increase of the bit rate to 1Gbit/s) more than any other systems, which makes Profinet the fastest and most universal real-time Ethernet system which offers the openness for TCP/IP and IT communication at the same time.
