Current market figures for PI (Profibus & Profinet International) confirm that in April 2008 the number of installed Profibus nodes in manufacturing and process plants broke the 25million barrier. Exactly one year previously, in April 2007, PI had broken the 20million node barrier. The installed base has therefore increased by 25 per cent in just one year. The current rate of growth is 5million Profibus nodes per annum.
Jörg Freitag, PI Chairman, says: "With more than 25million installed devices - probably more than all other rival systems combined - Profibus now dominates all sectors of industrial automation. The total value of the Profibus market is estimated at 50billion US dollars with every indication that this is still a growing market. We fully expect Profibus to exceed 30million nodes by the beginning of 2009."
A key factor in the market success of Profibus is the quality assurance and certification system of PI. The Profibus certification test by independent accredited test laboratories ensures that the tested devices comply with the respective specifications, a fact that reassures users and manufacturers alike and gives them confidence in their investment decisions. Customers value not only the comprehensive range of Profibus products, but also the large number of manufacturers, which gives them the freedom to select providers suited to their requirements.
This market success attests to the continuous activities of PI, which is committed to promoting the continual growth of this successful fieldbus system, while at the same time paving the way for a smooth transition to Profinet.
