Open communication in building automation, controls and building management - Control Network Protocol - Part 7: Communication via internet protocols
This document specifies a communication protocol for networked control systems. The protocol provides peer-to-peer communication for networked control using web-services. The document describes services in layer 2 and layer 3.
The layer 2 (data link layer) specification also describes the MAC sub-layer interface to the physical layer. The physical layer provides a choice of transmission media. The layer 3 (network layer), as described in EN 14908 1, is integrated in UDP/IP communication using IPv4 and IPv6 protocols.

Réseau ouvert de communication de données pour l'automatisation, la régulation et la gestion technique du bâtiment - Protocole de contrôle du réseau - Partie 7 : Communication via les protocoles internet
Le présent document spécifie un protocole de communication pour les systèmes de contrôle en réseau. Le protocole établit une communication de poste à poste pour le contrôle en réseau à l’aide de services Web. Le présent document décrit les services afférents aux couches 2 et 3.
Les spécifications de la couche 2 (DLL, Data Link Layer) décrivent également la sous-couche MAC (Media Access Control), interface avec la couche physique. La couche physique procure un choix de supports de communication. La couche 3 (couche réseau) comme décrite dans l’EN 14908 1, est intégrée aux communications in UDP/IP à l’aide des protocoles IPv4 et IPv6.
Odprta izmenjava podatkov v avtomatizaciji stavb, regulaciji in upravljanju stavb - Protokol regulacijske mreže - 7. del: Komunikacija preko spletnega protokola
Ta evropski standard določa komunikacijski protokol za omrežne regulacijske sisteme. Protokol omogoča medsebojno komuniciranje za mrežno regulacijo s pomočjo spletnih storitev. Standard opisuje storitve v slojih 2 in 3. V specifikaciji sloja 2 (podatkovno-povezovalni sloj) je opisana tudi povezava med podslojem MAC in fizičnim slojem. Fizični sloj ponuja izbiro različnih prenosnih medijev. Sloj 3 (omrežni sloj), kot je opisan v standardu EN 14908-1, je integriran v komunikacijo UDP/IP z uporabo protokolov IPv4 in IPv6.
