KNX releases Version 3.0 for IoT

Business news |
By Nick Flaherty


The KNX Association has launched Version 3.0 of the interconnect standard to align with IPv6 for the Internet of Things (IoT).  

This is the first major release of the KNX Standard since the publication of Version 2.1 in 2013 and adds the KNX IoT 3rd Party API and the KNX IoT Point API. This opens up development possibilities for KNX members. In addition to designing KNX products based on TP, RF and KNXnet/IP, the specifications add the possibility to interface more easily to KNX Installations via RESTful Web Services and allows manufacturers to design KNX products using IPv6 networks, such as Thread, as a communication medium.

The KNX Standard now includes specifications for three supported media (TP, PL and RF in its Ready and Multi flavours), one common system stack (including all of the allowed profiles), security mechanisms for KNX Classic (KNX Secure), KNXnet/IP specifications and now also specifications for KNX IoT 3rd Party and Point API (including their own security requirements).

Still included are updated versions of the Hardware Requirements, Certification Manual, Application Specifications, Test Specifications, Requirements for Basis & System Components and Application Specific Standards such as Logical Tag Extended and M-Bus Mapping.

The association expects the KNX IoT specifications to be further improved with more features and enhanced test specifications.

The standard includes application notes in the body text of the KNX Standard to add system extensions and corrections to and from the body text. When all of these are integrated, all requirements are found in one single place, instead of being spread over multiple documents.

Following publication, all members who have signed the IPR (Intellectual Property Rights) License Agreement will now be invited to come forward with any necessary patents they may hold on aspects that are explicitly described in the standard or are necessary to meet the requirements imposed by the standard. This process normally takes approximately a year to finalise.

Once the IPR process has been finalised, KNX Association plans to offer version 3.0 for download by anyone via MyKNX, not just KNX members.
