Application Profiles

‘Profiles’ define application-specific functionality to ensure the openness of PROFIBUS and PROFINET is utilized consistently.

PI Profiles can cover simple devices such as encoders by defining how signals are used and how they are physically connected.    However, profiles are increasingly covered more  complex systems or requirements. Profiles such as PROFIdrive and PROFIsafe deliver active functionality as well. An advanced profile covering active power management for end devices like lasers and robots is now under development with the aim of bringing significant reductions in energy consumption for the automotive industry.

Profiles guarantee quicker system design and they support faster device interchange, promoting competition amongst vendors, increased choice for users and full interoperability.


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 PROFIBUS and PROFINET.
