PROFINET uses Industrial Ethernet as communication medium and has many advantages if you want to bring Ethernet and Internet to the factory floor. However, the office world where Ethernet has been so successful is very different from the industrial world where electrical shocks, humidity, high temperature, moving parts, and EMR are constantly present. Not only the cables, connectors, and switches have to be industrialised (e.g. using rugged and metal housing) but also the multiple protocols worked so well for the Internet have to be selected and extended to meet the requirements for determinism and speed. With both TCP/IP and real-time protocols, PROFINET will be the future backbone network linking lower level fieldbus instruments and upper level enterprise functions making information technology an increasingly integral part of the automation industry.
Manfred will show developers how PROFINET works and how PROFINET solves real-time communication utilising and enhancing the existing Ethernet protocols.
