Impressive node counts in anniversary year
Users and manufacturers are increasingly relying on the communication technologies of PI

Right on time for its 25-year anniversary, PROFIBUS & PROFINET International (PI) can shine by impressive node counts. With 10 million PROFINET devices installed in the market today, another goal has been reached. “PROFINET stands for reliable and sustainable communication technology. That is why many many industrial enterprises – both manufacturers and users – are increasingly relying on PROFINET”, commented Karsten Schneider, Chairman of PROFIBUS & PROFINET International (PI) on the latest node counts. The steep growth curve is set to continue. This is consistent with the forecasts of an ARC market study of trends in Ethernet-based systems, which stated that the growth of PROFINET is expected to exceed that of its competitors and the general Industrial Ethernet market. In the future, ever greater amounts of data will have to be transferred to autonomous systems, higher-level systems such as MOM (Manufacturing Operation Management), or other locations via the cloud. PROFINET is the only standard that combines the strict real-time requirements of high-performance machines with the necessary openness for IP communication.


“Users are won over by the integrated overall concept,” named Schneider as another aspect of PROFINET's success. For example, the combination of PROFIsafe and PROFINET is an important deciding factor for the automotive industry, in particular. This is also reflected in the number of PROFIsafe nodes installed, which exceeded the 4 million mark this year. In 2014 alone, over 1 million new PROFIsafe nodes were installed, setting a new record. Outside of the automotive industry, PROFIsafe has been ensuring safety for the past 15 years in amusement rides, cable cars, passenger transportation, synchrotrons, and in particular throughout the machine building sector as well as in many other applications.


Even though it has been on the market for a long time, PROFIBUS continues to report impressive market growth. At the end of 2014, nearly 51 million PROFIBUS devices were installed in industrial plants worldwide, about 3.6 million more than the previous year. This number shows that user confidence in PROFIBUS is as high as ever. PROFIBUS PA is also recording steady growth. Around 9 million PA devices are now installed in the process automation sector including around 800,000 more than in 2013. This sector will receive special attention at PI in the Achema year. Accordingly, PI is currently working closely with users to in introduce the requirements of process automation in PROFINET. 


“It is our international network, above all, that is responsible for the success of PI technologies,” said Schneider. “More than 1500 member companies worldwide are involved in applying their expertise to develop reliable and future-proof communication solutions.” PI thus represents the world's largest and most influential interest group in the field of industrial communications.
