DIN EN 13321-2:2013-03 EN 13321-2:2012 (E) 5 Introduction This European Standard is intended for the design of new bui

27、ldings and the 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 impl

28、emented within 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

29、 consists of 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

30、” as well as 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 Da

31、ta Acquisition) 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

32、 off-line, e.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 BACn

33、et system environments. 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

34、 general overview of KNXnet/IP and covers security considerations. Clause 2, Core specification DIN EN 13321-2:2013-03 EN 13321-2:2012 (E) 6 Clause 2 “Core Specification” defines a standard protocol which is implemented within KNXnet/IP devices and Engineering Tool Software to support KNX data excha

35、nge over IP networks. This specific implementation of the protocol over the Internet Protocol (IP) is called KNXnet/IP. This standard addresses: definition of data packets sent over the IP host protocol network for KNXnet/IP communication; discovery and self-description of KNXnet/IP servers; configu

36、ration and establishment of a communication channel between a KNXnet/IP client and a KNXnet/IP server. Clause 3, Device Management Clause 3 “Device Management” defines services for remote configuration and remote management of KNXnet/IP servers. Clause 4, Tunnelling Clause 4 “Tunnelling” defines ser

37、vices 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 point-to-point exchange may be established by a super ordinate system for building automation or management functions or by an Engineering Tool Software. I

38、t supports all ETS functions for download, test, and analysis of KNX devices on KNX networks connected via KNXnet/IP servers. This includes changes of single KNX device object properties. Tunnelling assumes that a data transmission round-trip between a KNXnet/IP Tunnelling client and KNXnet/IP serve

39、rs takes less than tKNX_transfer_timeouts. Clause 5, Routing Clause 5 “Routing” defines services for a point-to-multipoint exchange of KNX telegrams over an IP network between KNXnet/IP routers and/or KNX/IP devices. Clause 6, Remote Diagnosis and Configuration Clause 6 “Remote Diagnosis and Configu

40、ration” 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 services provide means for diagnosing communication settings and for changing these remotely. DIN EN 13321-2:2013-03 EN 13321-2:2012 (E) 7 1 Scope This Euro

41、pean 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 transmission speed)

42、 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 annunciation); fast inte

43、rface 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, KNX-PL132); a KNX

44、-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 client (e.g. running

45、 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. DIN EN 13321-2:2013-03 EN 13321-2:2012 (E) 8 Figure 1 Device types and conf
