How to get hold of a copy of the KNX Specifications


If your company has joined the KNX Association as a Shareholder, a Licensee (Royalty-per-Unit License/Sub-License) or as an Interested Party, a copy of the officially released KNX Specifications (currently version 2.1) will be made available as soon as you become member. However, as a member you will also have access to the latest working documents of any updated and new specifications parts, which are currently under discussion in KNX expert and working groups: these documents do not form part of the officially released KNX specifications.


If you are not Member, you have 2 options:

  • Purchase copy of EN 50090 or ISO/IEC 14543-3-1 to 7 standard at your national standardisation body.
  • Obtain a copy of the officially released KNX specifications via a personal account in MyKNX . Start an order in the Shop section and select the KNX specifications:  they will be offered for download free of charge. You will however not receive access to any updated or new parts at your disposal, this is reserved for KNX Members only.
