10 Page 10 of 73 2 LOGICAL DEVICES AND ASSOCIATIONS, M-BUS MODELLING (GENERAL CONCEPT) In DLMS/COSEM, metering equipment is modelled in physical and logical devices. The actual device is the physical device. The physical device can contain multiple logical devices. For this companion standard it is decided that there will be only 1 logical device (the management logical device). Physical device Management device Association object Logical device name Logical Other object Other object 2.1 Clients The logical device has at least 3 associations: Public client (client Id 16), management client (client Id 1) and pre-established client (client Id 102). There will be no direct connection to the M-bus device (used by P2) via the P3 interface. Access to the M-bus device has to be done with the objects offered by the logical device Public client Public client is for test purpose. Due to the fact that the public client is with lowest security (no security), it must not allowed to read metering data, or perform any programming. The services which must be supported within the Public client are: - Block transfer with Get - Get - Selective access
11 Page 11 of Pre established client The pre-established client is for broadcast purposes. It has to be used by the data concentrator, each time a broadcast service is needed. The services which must be supported within the Pre established client are: - Block transfer with Set - Set - Selective access - Action Management client The management client (Client Id 1) is the client to be used by the data concentrator or the central access server in the case of GPRS and Ethernet meters, for regular point to point connections with the meters. This client must be able to perform any allowed operation on the devices, gathering with its own privileges, the ones of the public client and the pre-established client. Additionally, this client is the addressee of the event notification request. It has Get, Set, Action and Event notification facilities. The services which must be supported are within the Management client:: - Block transfer with Get - Block transfer with Set - Set - Get - Selective access - Event notification - Action 2.2 Access right For each client, access right of each attribute for all the objects defined inside this document must be managed. This concerns Get, Set and Action access right. According to the client, a given attribute may not be accessible either for Get or Set or Action facility. When the get, set or action service is not managed for an attribute, the result to return back in the case of an access attempt must be read-write-denied result. This must not be consider as a protocol error. Management client must be able to manage all the necessary attributes access for a normal eploitation and maintenance of any network used. There will be no direct connection to the M-bus device (used by P2) via the P3 interface. Access to the M-bus device has to be done with the objects offered by the logical device..
12 Page 12 of 73 3 COMMUNICATION PROFILES AND SERVICES, SECURITY This chapter gives the required and selected communication profiles and the security requirements to be implement for the P3 interface. There are three communication profiles selected for the Dutch Smart meter. These are: GPRS Ethernet PLC DLMS/COSEM will use only the pull mechanism for the application layer 3. The description how the E-meter will establish a GPRS connection has been added to the profiles part (see chapter 3.1.1). The profile for GPRS meters and Ethernet uses standard COSEM TCP/IP profile as defined in IEC or in DLMS UA Green Book edition 6. The TCP/UDP based profile is given in figure 3.1. Log_Dev_1 (management) COSEM Application layer ACSE DLMS ASE # 01 COSEM Transport layer COSEM wrapper The DLMS/COSEM TCP based profile uses the standardized port number Transport layer TCP or UDP DLMS/COSEM Port 4059 Network layer IP Data link layer e.g. Ethernet Physical layer e.g. Ethernet Figure 3.1: TCP/UDP based profile 3 The operation principle used in this document is based on client / server model. Ecept for the Event notification which is based on unsolicited message sending for alarm management, for all the other services the client always asks for a request and the server send back the response of the concerned request. With respect to event notification, a GPRS meter shall be able to send an unsolicited message. The grid operator shall have the ability to configure which alarms will be sent unsolicited. Also channel set-up will be initiated by the GPRS meter.
13 Page 13 of 73 The required setup objects for TCP/UDP, IPv4 and PPP will be described below. For the detailed attribute descriptions and methods see chapter 4.2 for the relevant paragraph of the Blue book . TCP-UDP setup (Class ID: 41) To set up the TCP or UDP sub-layer of the COSEM TCP or UDP based transport layer 1 Logical name Octet-string 0-b: TCP-UDP_port long-unsigned Default IP_reference octet-string 4 MSS long-unsigned Min=40, ma=65535, default=576 5 nb_of_sim_conn unsigned Value=1 6 inactivity_time_out long-unsigned Default=180 An instance of the TCP-UDP setup class contains all data necessary to set up the TCP or UDP sub-layer of the COSEM TCP or UDP based transport layer of a TCP-UDP/IP based communication profile. In TCP-UDP/IP based communication profiles, all AAs between a physical device hosting one or more COSEM client application processes and a physical device hosting one or more COSEM server application processes rely on a single TCP or UDP connection. The TCP or UDP entity is wrapped in the COSEM TCP-UDP based transport layer. Within a physical device, each application process client application process or server logical device - is bound to a Wrapper Port (WPort). The binding is done with the help of the SAP Assignment object. On the other hand, a COSEM TCP or UDP based transport layer may be capable to support more than one TCP or UDP connections, between a physical device and several peer physical devices hosting COSEM application processes. NOTE When a COSEM physical device supports various data link layers (for eample Ethernet and PPP), then an instance of the TCP-UDP setup object is necessary for each of them. IPv4 setup (Class ID: 42) Handles all information that is related to the IP Address settings associated to a given device and to a lower layer connection on which these settings are used. 1 Logical name octet-string 0-b: DL_reference port octet-string 3 IP_address double-long-unsigned 4 multicast_ip_address array 5 IP-options array 6 Subnet_mask double-long-unsigned 7 gateway_ip_address double-long-unsigned 8 use_dhcp_flag boolean 9 primary_dns_address double-long-unsigned 10 secondary_dns_address double-long-unsigned An instance of the IPv4 setup class handles all information that is related to the IP Address settings associated to a given device and to a lower layer connection on which these settings are used.
14 Page 14 of 73 There shall be an instance of this class in a device for each different network interfaces implemented. PPP setup (Class ID: 44) Handles all information that is related to PPP settings associated to a given physical device and to a lower layer connection on which these settings are used. 1 logical_name Octet-string 0-b: PHY_reference Octet string 3 LCP_options LCP_options_type 4 IPCP_options IPCP_options_type 5 PPP_authentication 4 PPP_auth_type There shall be an instance of this class for each network interface of a physical device, using the PPP protocol. 3.1 Communication profiles The three specific communication profiles are given in the following paragraphs GPRS communication profile GPRS Application Process COSEM Interface Objects IEC , Application Layer COSEM Application Layer IEC COSEM IP Transport Layers IEC COSEM Wrapper TCP or UDP IP Media Dependant Lower Layers Data Link Layer Physical Layer SNDCP LLC RLC MAC GSM Radio Figure 3.2: GPRS communication profile 4 Be aware that if care is not brought to these attribute, even they are managed by the manufacturers, they may be unusable. For eample: as the same way the length of the meter Id is fied, the specification must determine the maimum length of user name & password too

On the server side, only one of them may be implemented. On the Client side, one or more of them may be implemented.the Client (concentrator) finds out the kind of LLC layer used by the server during the Discovery / Registration process and maps the LLC type to the System title.
17 Page 17 of 73 The PLC solution requires support of ISO/IEC , allowing to plug in TCP/IP later. This can co-eist with the IEC LLC layer and the IEC data link layer used in eisting implementations. The selected LLC layer is ISO/IEC LLC layer. The other two are only allowed for backwards compatibility reasons. The nine PLC setup objects are given below with their OBIS codes.

A selection of which modulation band to use, shall be tuned after practical eperiences in the field. The selection depends of the architecture of the Dutch Grid in general.
18 Page 18 of COSEM Security Both access and message security are required to address the requirement for confidentiality and authentication in DLMS/COSEM communication protocol. COSEM Security should be implemented as described in DLMS UA Green Book edition 7 and DLMS UA Blue Book edition 9. Because these documents are not yet published the COSEM security requirements and way to implement are given in reference . Access Security DLMS/COSEM access security provides Low Level Security (LLS) and High Level Security (HLS) authentication mechanisms. LLS enable client only authentication with password and HLS enable client/server authentication with challenge mechanism. Authentication is used for association establishing. Associations offer specific view to COSEM objects with associated access rights to individual objects. During the setup of the connection (the application association) HLS should be used. The Management Logical device should be accessible without security. Message Security DLMS/COSEM message security provides encryption and authentication of the COSEM APDU with standard symmetric key algorithms. It provides combined confidentiality and authentication using GCM cipher mode of operation. Encryption is used to provide confidentiality for data. The data to be protected is called plaintet. Encryption transforms the data into Ciphertet. Ciphertet can be transformed back into plaintet using decryption. Message authentication and encryption should be used in all situations and the Advanced Encryption Standard (AES) is the selected algorithm for ciphering. Selected Security Suite: Security Suite Id Authentication Algorithm Encryption Algorithm 7 AES-GCM-128 AES-GCM-128 Note: Security Suite 7 uses Combined Mode of operation with Authentication and Encryption. This choice covers etensive security at authentication and encryption level and realise full interoperability.
19 Page 19 of 73 4 OVERVIEW OF OBJECT MODEL The object model of the Dutch smart meter is divided in three parts: a. Abstract objects (chapter 5) b. Electricity related objects (chapter 6) c. M-bus related objects (chapter 7) Before all the required objects for the Dutch smart meter are described in more detail in the mentioned chapters an overview will be given of all required profiles. Further an eplanation of the event and error handling is described in paragraph 4.2 of this chapter for better understanding how the required objects for covering that functionality are related to each other. 4.1 Profile structure Dutch smart meter In figure 4.1 the profiles are summarized which will be required in relation to the Dutch smart meter requirements. The Monthly billing values (combined) object is described in more detail in paragraph 5.5 (Abstract objects). The Daily load profile values (E only) and 15 min load profile values are described in more detail in paragraph 6.3 (Electricity related objects). The Hourly load profile values (per channel) are part of paragraph 7.4 (M-bus related objects). 0-0: monthly billing values (combined) captured object list = clock;+a rate 1;+A rate 2; A rate 1; A rate 2;M-bus register channel 1 to 4 capture period = triggered from a single action scheduler at the end of every month profile entries = 13 (13 month) Note: Just for storage in case of problems, not read by CAS regularly P3 0-4: : : Daily load profile values (E only) 1-0: min load profile values (E only) 0-2: : Hourly load profile values (per channel) captured object list = clock; E-status; +A rate 1, 2; A rate 1, 2; capture period = s (daily) profile entries = 10 (10 days) captured object list = clock; E-status; +A; A capture period = 900 s (15 min) profile entries = 960 (10 days) captured object list = clock; status; M-Bus register capture period = 3600 s (60 min) profile entries = 240 (10 days) Note: All load profiles contain eactly one entry per capture period (no gaps, no additional entries). This also applies in case of time shifts and/or power outages Note: Either captured every hour or once a day P3 P3 P3 (P1) Figure 4.1: Structure of profiles of Dutch Smart meter

Standard Event Log Error Register Alarm Register >0 Alarm Events Filter Filter Filter Filter Filter Filter All general events, e.g changes of the clock, changes of the configuration, clearing of profiles, all kind of self check errors, activation of new parameters, activation of new time of use, etc. Control Log 100 entries Events related to the disconnector, e.g connect, disconnect, changing of the disconnector threshold. Power Failure Log Duration of long power outages Fraud Detection Log 10 entries 10 entries Events related to fraud attemps, e.g removal of terminal cover, removal of meter cover, strong DC field detection, access with wrong password M-Bus Event Log 30 entries All events concerning the M-bus devices, e.g changes of the clock, communication erros, etc. 30 entries M-Bus Control Logs Filter Changes of the states related to a M- Bus disconnector, e.g. a gas valve, (connect, disconnect). 1 instance per M-Bus device 10 entries A lot of events are generated by the meter itself or by its environment. All these events are logged in several event logs. The objects are described in chapters 5, 6 and 7 in more detail. Additionally they are also used to set and clear errors as well as to trigger alarms. The diagram above gives an overview about the handling, the details of the objects are described in the chapters 5, 6 and 7.
