KNX Specifications

1

Primer

•  

• The primer gives a general overview of the whole KNX system and philosophy, and will be useful to all people like product managers, developers, quality assurance people, ... wanting to have a basic knowledge of the KNX system.
• This volume is still under preparation, for the time being we refer therefore to Chapter 3/1/1 “Architecture”.

2

Guide for Development

•  

• Basis for the knowledge needed for development of products based on the KNX technology. It will lead technical people to a sufficiently detailed know-how of this technology in order to develop products in this environment.
• This Volume is also under preparation, it will be built on the contributions of the main system providers within the KNX Association.

3

System Specification

•  

• This volume is the main part of the KNX Specification.
• It shall be used as a reference for hardware and software development of products. As such you need only to refer to the corresponding parts relevant for your development: Architecture, Communication Media, Communication, Application Environment, Management, Standardized Interfaces, Interworking, KNXnet/IP and Supplements.

4

Hardware Specification and Tests

•  

• Provides you with the constructional requirements for KNX devices, dealing mainly with electrical, functional, environmental Conditions and Quality features needed to comply with the KNX certified design quality level.

5

Certification

•  

• Defines the necessary requirements, steps, and procedures to obtain from the KNX Association the granting of the KNX Trademark for products or services.
• It will be particularly useful for people in charge for obtaining the KNX Trademark

6

Profile

• A profile is one allowed and minimal combination within the rich set of system features. Profiles classify the implementation in categories enabling development and certification of KNX certifiable devices and systems. Profiles are certification relevant, as only devices or systems compliant to at least one profile may be KNX certified.

7

Application Descriptions

•  

• This volume describes the KNX application models grouped per Application Domain: lighting, shutters and blinds, HVAC, access control.
• The application model is described with Functional blocks with standard Datapoints and detailed behaviour to the level necessary to guarantee Interwoking.
• This volume also contains the E-Mode Channel definitions.

8

System Conformance Test

• Guidelines for testing: test specifications for the media on which the KNX protocol has been implemented.
• Contains test specifications for the KNX protocol stack layers, especially relate to the KNX Link, Transport, Network and Application Layer.
• Contains test specifications for the Standardized Interfaces and  test specifications for the defined KNX Interworking Standards.

9

Standardized Components & Devices and Tests

•  

• Describes the requirements and tests for certification of standardised and non-standardised KNX cables and connectors and KNX basic components.
• Describes the tests for certification of standardised KNX interfaces and couplers.
  
• Describes the requirements and tests for all currently available and standardised Bus Coupling units and Bus Interface Modules

10

Application Domain Specific Standards

•  

• Describes the specifications for use in specific application fields.
• It contains the HVAC Easy Extension (HEE) part, designed especially for HVAC.
• It also contains the requirements of the support of M-Bus in KNX.
