Hello HVK; There are many sources of information on Profinet available, both on this site and on the web; search for more threads on the same subject as yours.

If you are interested in the basis of Ethernet standards, look at this presentation: IEEE - Wikipedia The document I proposed at the beginning Profinet system description shows a graph explaining the relationship between Ethernet and Profinet: look at the very bottom of the diagram, way down, you will find the IEEE standards as a base for development of Profinet standards, protocols and application profiles.

IEEE Ethernet is used to connect nodes in a Local Area Network. The physical link between nodes in an Ethernet network can be, for example, a twisted pair cable, or a fiber optic cable. Nowadays, Ethernet is the most common communication medium worldwide; used in homes, enterprises, factories, and in general infrastructure due to its speed, affordability, and versatility.

It is a communication protocol to exchange data between controllers and devices. It defines cyclic and acyclic communication between components, including diagnostics, functional safety, alarms, and other related information.

There is considerable interest in the advancement of Ethernet technology, and standards bodies such as IEEE are supporting the cause. In IEEE began a set of standards for networks [5] , including specific standards for Ethernet. The technology defined by IEEE is currently being used in the following industries: telecommunications, power generation and distribution, industrial automation, robotics, data acquisition, test and measurement.

However, during the ODVA conference [6] , Paul Didier of Cisco noted that these products would be available within the next two years. Real-time synchronization can be achieved over conventional Mbps, Ethernet systems with a switch-based architecture. Despite the shortcomings of Ethernet itself, either network protocol is suitable for automation applications.

Both networks are open and have the support of extensive communities. More importantly, they are backed by the two largest automation companies in the world today.

There are a couple notable differences:. Neither of these points tends to promote one option over the other. Both will evolve to offer better performance. Selection may simply come down to geography. Profibus and Profinet are the market leaders in Europe. If you are looking for support from a local distributor or integrator in the U. Jeff is a Gen Xer who is adaptive to change and open to ideas.
