International Standardization is an important foundation for product design, development and use. Standards underpin interoperability and guarantee consistent performance and high quality for end users.

The major PI application profiles are standardized as follows:

  • PROFIsafe:IEC 61784-3
  • PROFIdrive: IEC61800-7
  • Low Voltage Switch Gear: IEC 61915 (under development)

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.
