About PI North America

PI North America was founded as the PROFIBUS Trade Organization in 1994 and was generally known as simply PTO.  Although an autonomous non-profit trade organization, PTO renamed itself to PI North America to more closely identify with the international umbrella organization, PI (PROFIBUS & PROFINET International).

PI North America is dedicated to supporting industry in achieving beneficial results using the PROFIBUS, PROFINET, IO-Link, and omlox technologies. PI North America also assists device manufacturers in the development and marketing of PROFIBUS, PROFINET, IO-Link, and omlox products.

Over 1,500 companies organized into 27 Regional PI Associations develop and supply fieldbus and Industrial Ethernet solutions for cost efficient and highly reliable automation.

The PI Community

PI is the largest industrial networking standards organization in the world and it is the umbrella organization responsible for the PROFIBUS, PROFINET, IO-Link, and omlox technologies. Its standardization efforts and commitment to openness have guaranteed leading-edge, certified-interchangeable products from an enormous range of suppliers. It has been doing business with PROFIBUS since 1989 and a measure of its success is that there are over 69 million PROFIBUS devices in use today. First PROFINET specifications became available in 2002 and there are more than 65 million PROFINET devices installed today. IO-Link was brought into the organization in 2009 and as to date more than 40 million IO-Link devices have been installed worldwide.


As one of those 27 local PROFIBUS and PROFINET organizations, PI North America, a non-profit, member organization, is responsible for North America. Members of PI North America are vendors of hardware, software and systems, as well as end users and operators, scientific institutes, universities, distributors, and system integrators. PI North America supports its members with a range of services such as joint marketing projects, road shows, training classes, product certification, strategy meetings and webinars.
