Standardization (IEC)

IO-Link is a fieldbus independent and manufacturer independent communication standard and can be integrated into any existing fieldbus via a corresponding interface. This fieldbus independence allowed the creation of a corresponding specification by the IO-Link community, which has already been published by the IEC (International Electrotechnical Commission) as IEC 61131-9 (International Standard).

IO-Link device profile

A smart sensor profile was also made available by the consortium. The standard functions of IO-Link devices are described in it. So, the user (e.g. mechanical engineering) can be sure when using devices from different manufacturers that the specified functions can always be found at the same indices.
