21、ical Committee CEN/TC 247 “Building Automation, Controls and Building Management”, the secretariat of which is held by SNV. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2013, and conflicti

22、ng national standards shall be withdrawn at the latest by June 2013. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document sup

23、ersedes EN 13321-2:2006. Whereas ENV 13321-2:2000 described the transmission of EIB packets over Ethernet including the frame encoding, this document describes the transmission of HBES packets using the Internet Protocol. Details of the HBES packet frames are covered in part 1 of EN 13321, removing

24、the need to explicitly describe the HBES frames in this document. This document is Part 2 of the EN 13321 series of European Standards under the general title Open data communication in building automation, controls and building management Home and building electronic systems, which consists of the

25、following parts: Part 1: Product and system requirements; Part 2: KNXnet/IP communication. According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Cz

28、e retrofit of existing buildings in terms of acceptable indoor environment, practical energy conservation and efficiency. This standard defines the integration of KNX protocol implementations within the Internet Protocol (IP) named KNXnet/IP.It defines a standard protocol, which is implemented withi

29、n KNX devices, Engineering Tool Software (ETS) and other implementations to support KNX data exchange over IP networks. In fact, KNXnet/IP provides a general framework, which accommodates several specialised “Service Protocols” in a modular and extendible fashion. The KNXnet/IP standard consists of

30、the following clauses: Clause 1, Overview Clause 2, Core Specification Clause 3, Device Management Clause 4, Tunnelling Clause 5, Routing Clause 6, Remote Diagnosis and Configuration Additional clauses may be added to the KNXnet/IP standard in the future at which time Clause 1 “Overview” as well as

31、Annex A will need to be updated. KNXnet/IP supports different software implementations on top of the protocol. More specifically, these software implementations can be Building Management, Facility Management, Energy Management, or simply Data Base and SCADA (Supervision, Control and Data Acquisitio

32、n) packages. Most of these packages need to be configured for the specific user application. In order to simplify this process and cut costs for engineering, KNXnet/IP provides simple engineering interfaces, namely a description “language” for the underlying KNX system. This may be done off-line, e.

33、g. generated as an ETS export file, or on-line by a mechanism that self-describes the underlying KNX system (reading data from the system itself). In conjunction with the EIB/KNX-to-BACnet mapping described in EN ISO 16484-5, EIB/KNX installations can very easily be integrated into BACnet system env

34、ironments. KNXnet/IP supports: on-the-fly change-over between Operational modes (configuration, operation); event driven mechanisms; connections with a delay time greater than tEIB_transfer_timeout(e.g. network connection via satellite). Clause 1, Overview Clause 1 “Overview” provides a general over

35、view of KNXnet/IP and covers security considerations. Clause 2, Core specification BS EN 13321-2:2012Copyright European Committee for Standardization Provided by IHS under license with CENNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-EN 13321-2:2012 (E) 6 Clause

36、2 “Core Specification” defines a standard protocol which is implemented within KNXnet/IP devices and Engineering Tool Software to support KNX data exchange over IP networks. This specific implementation of the protocol over the Internet Protocol (IP) is called KNXnet/IP. This standard addresses: def

37、inition of data packets sent over the IP host protocol network for KNXnet/IP communication; discovery and self-description of KNXnet/IP servers; configuration and establishment of a communication channel between a KNXnet/IP client and a KNXnet/IP server. Clause 3, Device Management Clause 3 “Device

38、Management” defines services for remote configuration and remote management of KNXnet/IP servers. Clause 4, Tunnelling Clause 4 “Tunnelling” defines services for point-to-point exchange of KNX telegrams over an IP network between a KNXnet/IP device acting as a server and a KNXnet/IP Client. This poi

39、nt-to-point exchange may be established by a super ordinate system for building automation or management functions or by an Engineering Tool Software. It supports all ETS functions for download, test, and analysis of KNX devices on KNX networks connected via KNXnet/IP servers. This includes changes

40、of single KNX device object properties. Tunnelling assumes that a data transmission round-trip between a KNXnet/IP Tunnelling client and KNXnet/IP servers takes less than tKNX_transfer_timeouts. Clause 5, Routing Clause 5 “Routing” defines services for a point-to-multipoint exchange of KNX telegrams

41、 over an IP network between KNXnet/IP routers and/or KNX/IP devices. Clause 6, Remote Diagnosis and Configuration Clause 6 “Remote Diagnosis and Configuration” defines services for a point-to-point exchange of KNX telegrams over an IP network between KNXnet/IP routers and/or KNX/IP devices. The serv

42、ices provide means for diagnosing communication settings and for changing these remotely.

43、1 Scope This European Standard defines the integration of KNX protocol implementations on top of Internet Protocol (IP) networks, called KNXnet/IP. It describes a standard protocol for KNX devices connected to an IP network, called KNXnet/IP devices. The IP network acts as a fast (compared to KNX tr

44、ansmission speed) backbone in KNX installations. Widespread deployment of data networks using the Internet Protocol (IP) presents an opportunity to expand building control communication beyond the local KNX control bus, providing: remote configuration; remote operation (including control and annunci

45、ation); fast interface from LAN to KNX and vice versa; WAN connection between KNX systems (where an installed KNX system is at least one line). A KNXnet/IP system contains at least these elements: one EIB line with up to 64 (255) EIB devices; OR one KNX segment (KNX-TP1, KNX-TP0, KNX-RF, KNX-PL110,

46、KNX-PL132); a KNX-to-IP network connection device (called KNXnet/IP server); and typically additional software for remote functions residing on e.g. a workstation (may be data base application, BACnet Building Management System, browser, etc.). Figure 1 shows a typical scenario where a KNXnet/IP cli

47、ent (e.g. running ETS) accesses multiple KNX installed systems or KNX subnetworks via an IP network. The KNXnet/IP client may access one or more KNXnet/IP servers at a time. For subnetwork, routing server-to-server communication is possible. BS EN 13321-2:2012Copyright European Committee for Standar
