PROFINET - the leading Industrial Ethernet Standard

PROFINET has become the leading Industrial Ethernet Standard in the market. This globally established and future-oriented technology is supported by many product vendors, thus ensuring long-term availability and investment protection. With the total number of PROFIBUS and PROFINET products so far installed at plants has exceeded 104 million, an impressive threshold has been crossed. On a yearly basis, PROFINET has beaten all previous records in 2021 with a total of another 8.5 million products placed on the market. The number of installed PROFINET devices rose by more than 20% in comparison to the previous year, reaching a combined total of 48.2 million

All Industries and Branches

PROFINET uses the same Ethernet as offices and IT departments. However, its capabilities have been enhanced to meet the far tougher conditions encountered in industrial applications.Whether the application involves factory automation, process automation, or drives (with or without functional safety), PROFINET is the first choice across the board. As technology that is standard in the automotive industry, widely spread in machine building, and well-proven in the food and packaging and logistics industries, PROFINET has found its way into all application areas.

PROFINET is designed for all branches of industrial automation engineering:


PROFIBUS is a standardized, open, digital communications system for all areas of application in manufacturing and process automation.


PROFINET is the innovative open standard for Industrial Ethernet. It satisfies all requirements of automation technology.

IO-LINK is an independent sensor / actuator interface solution for use with all automation technologies.



Omlox is an open technology standard for real-time indoor localization systems for industrial manufacturing.
