28、) 5 Introduction In March 2009, the European Commission issued a mandate M/441 for the standardization of smart metering functionalities and communication for usage in Europe for electricity, gas, heat and water applications to ensure interoperability of technologies and applications within a harmon

29、ized European market. As a result, a Technical Report, CEN/CLC/ETSI TR 50572, Functional Reference Architecture for Communications in Smart Metering Systems, was published in December 2011. As a consequence of this work and in line with the CEN/CLC/ETSI TR 50572 functional reference architecture, CL

30、C/TC 205, responsible for Home and Building Electronic Systems, was entrusted with the task to formulate standards for the communication from the smart metering system towards the home. BS EN 50491-11:2015EN 50491-11:2015 (E) 6 1 Scope This European Standard specifies a data model to abstract the me

31、tering world towards a simple external consumer display. The data model, as described by means of functional blocks contained in this European Standard, lays down the format of metering data accessible by a simple external consumer display. This data interface would be typically part of the meter co

32、mmunication functions and be accessed by a simple external consumer display via the H1 interface of the CEN/CLC/ETSI TR 50572 between the display and the meter communication functions. The data interface specified in this document may also be accessed by the LNAP or NNAP through the C or M interface

33、, after which the data could be accessed by HBES devices through the H2 and H3 interface. In other words, in this way the same data model can be used both on the H1 as well as the H2 and H3 interface. The document specifies neither the communication mechanisms used on the data interface, nor the app

34、lied data privacy and security mechanisms nor the ergonomics of the simple external consumer displays, where national regulations may apply. The document does also not specify the communication protocol used between the meters and the meter communication functions. However, it takes into account the

35、 existing European standards like the EN 13757 series (in particular EN 13757-3:2013 and its Annex O) and the EN 62056 series for the definition of the data model. 2 Normative References The following documents, in whole or in part, are normatively referenced in this document and are indispensable f

43、nce architecture diagram for smart metering communications as given in CEN/CLC/ETSI/TR 50572. In this European Standard, a functional block is specified for each typical metering function, grouping a number of in- and output data points, as depicted in Figure 1. Figure 1 depicts logical entities and

44、 not physical devices. NOTE 1 This standard does not define requirements for devices acting as data sources for the simple external consumer display (devices sending input on the I interface shown in Figure 1) and are covered by other European standards. In line with the M/441 architecture, the info

45、rmation flow on the H1 is predominantly from the meter communication function in one or more meters to one or more simple external consumer displays (or optionally one common display), whereby the latter acts as sink of the information obtained through the H1 interface from the meter communication f

46、unctions. Where necessary, the consumer display may poll data from the meter communication functions, e.g. historical values. In no case shall it be able to alter metering data through the consumer display. Hence, most functional blocks of the data interface specified in this European Standard conta

47、in data that are intended as output data to a connected display. BS EN 50491-11:2015EN 50491-11:2015 (E) 9 The data structures used on the H1 interface are part of this European Standard. All other underneath described interfaces are informative. NOTE 2 The wired Meter communication according to EN

48、13757-2 / EN 13757-6 is only applicable if it is used exclusively for the H1 interface. The functional blocks specified in this document may also be accessed by the LNAP or NNAP through the C or M interface, after which the data could be accessed bi-directionally with HBES devices through the H2 and

49、 H3 interface. The communication on the H2 and H3 interface is part of prEN 50491-12. For each connected metering function (Tx Meter in Figure 1), the corresponding metering communication function shall hold an entity of the corresponding functional block. The input for each connected metering function is supplied by meters complying with the EN 62056 and EN 13757 series and is not part of this standard. The input to the LNAP and NNAP is due to be part of the IEC 627461). The measurable quantities
