PI (PROFIBUS & PROFINET International) is publishing a new white paper demonstrating the versatility of PROFINET in a wide variety of applications. The publication demonstrates the strength of PROFINET as a universal Ethernet-based communication system. It is this attribute that makes PROFINET such a market success story. The number of installed PROFINET nodes published in March of 2009 backs this up. By the end of 2008, a notary-certified 1.6 million nodes were in use. This corresponds to an increase of 40% compared to the end of 2007. The white paper is available for download free of charge at the PI website (http://www.profibus.com/ pall/meta/downloads/#Brochures).
