PROFIBUS & PROFINET International (PI) is the world’s leading industry association, the active Community for the standardization and dissemination of industrial communication and information technologies, a core topic of digitalization, automation and Industry 4.0.

With its core technologies PROFIBUS, PROFINET, IO-Link and omlox, PI is responsible for the development of its market-leading, open standards for all fields of application in industrial manufacturing. PI achieves this goal with its 24 regional PI associations (RPAs), all of which are members of the international umbrella organization PI, and their 1,700 members.

PROFIBUS and PROFINET are the standardized solutions for this from PROFIBUS & PROFINET International (PI) that combine full integration with high application orientation. With its standardized protocol, PROFIBUS encompasses all subprocesses found in factory and process automation, including safety-related communication and drive applications, thereby providing the ideal basis for horizontal integration in an automation system. With its similarly standardized protocol, PROFINET enables not only horizontal communication but also vertical communication and thus the connection from the field to the corporate management level. Both communication systems are the basis for solutions that are comprehensively networked, integrated, and optimized for the respective automation tasks.
