The KNX Standard :: Interworking As mentioned in the introduction Interworking is a major asset of the KNX technology. An Interworking model and extensive functional block descriptions for many application domains are an integral part of the KNX specifications (Volume 3 Part 7 and Volume 7). This is backed up by a certification process, in which next to the conformity to the defined system profiles, compliance to at least the standardised data types or additionally the defined functional blocks is one of the cornerstones (as symbolised by the KNX Trademark). Interworking is defined in the KNX Interworking model as : 'the situation where products sending and receiving messages can properly understand signals and react on them without additional equipment'. In order to profit to the full extend of the use of a Home and Building Control system, it is indispensable that products of different manufacturers ("multi-vendor interworking") and products of different application fields ("cross-discipline interworking") interwork. The advantages of such interworking are : - it enhances the OEM market amongst KNX solution providers; - it gives easy market access for niche products (commonly made by smaller companies) - it allows to set up a common market infrastructure for KNX compatbile products (e.g. training measures) The agreement on common standardised data types and functional block specifications is reached in Application Specification groups of KNX members active in a certain application field (e.g. HVAC), after which the consistency of these proposals with the general interworking model is checked by the KNX Task Force Interworking. The underneath picture gives an example of an Inteworking specification. For a more detailed explanation of the various configuration media, please refer to the presentations of the KNX Technology Tutorial workshop.

Saradnja Uvod Interworking (međusobno delovanje) je glavna prednost KNX tehnologije i definiše se kao: “Situacija u kojoj proizvodi koji šalju i primaju poruke, bez dodatne opreme, mogu pravilno razumeti signale i reagovati na njih” Kako bi u potpunosti iskoristili prednosti koje pruža sistem upravljanja stambenim i poslovnim objektima, neophodno je da proizvodi različitih proizvođača ("multi-vendor interworking") i proizvodi različitih područja primjene ("cross-discipline interworking") mogu zajedno raditi. KNX Interworking: kako? Zahvaljujući strogim pravilima o međusobnom delovanju KNX sertifikovanih proizvoda, danas je sve moguće: - Pre svega, proizvodi koji su etiketirani KNX zaštitnim znakom, obavezni su “razgovarati i razumeti” KNX jezik, t.j. biti u stanju pravilno interpretirati analogne signale sa medija na koji su spojeni i bitove i bajtove kako stoji u KNX specifikaciji sistema; - Dalje, svi KNX sertifikovani proizvodi se mogu konfigurisati sa jednim jedinim alatom koji je nezavistan od proizvođača (ETS™) ili se koriste mrežnim resursima kako bi barem pročitali uređaje uz pomoć ovog alata; - I poslednje, ali ne i manje važno, pri realizaciji određene funkcije – npr. slanje informacije o temperaturi za vreme trajanja operacije – može biti jedino kodirano prema KNX specifikacijama o međusobnom delovanju. Za celi set funkcija (paljenje/gašenje, zatamnjivanje, kontrolu zastora, ceo broj i promenljive vrednosti, postotak, datum/sat, HVAC mod,...), KNX ima standardizovan kompletni set tipova podataka. Prednosti interworking-a u KNX-u Gore navedeni pristup je veoma pridoneo uspehu i statusu koji KNX danas uživa. Bez strogih kriterijuma međusobnog delovanja, ovo ne bi bilo moguće:
