Group DNP3 is administered by an independent body called the DNP Users Group, a consortium of device vendors and users of the protocol A function of this users group is to voluntarily register DNP3 implementations and to serve as an unbiased mediator to develop DNP3 for various classes of devices (i.e., meter, regulator, relay, etc.) Vendors, prior to beginning any DNP3 implementation, may become a member of the users group to identify what DNP3 developments already exist and which features should be supported for their device The – 230 – BS EN 61400-25-4:2008 61400-25-4 © IEC:2008(E) users group embodies a number of users and vendors who represent an experience base and market expertise that assures DNP3 developments are relevant to the largest body of potential users DNP3 uses data set prototypes to specify the structure and ordering of data within an entire data set or a portion of a data set This part of IEC 61400-25 specifies data set prototypes for use in DNP3 data sets DNP3 uses namespaces to assign unique meaning to common names that could otherwise be confused with the same name used elsewhere The DNP3 Users Group accepts voluntary registration of Namespaces submitted by any vendor or user Once a namespace is registered, the vendor or user is free to define, redefine or delete any data set prototype(s) within that namespace Each data set prototype is assigned a UUID when it is defined or modified to uniquely identify it Any user or vendor is free to make use of data sets defined by data set prototypes in any namespace where they have knowledge of those data set prototypes This permits the creation of private data sets where required and also permits definition of shared data sets for common usage, such as the data sets prototypes described in this part of IEC 61400-25 E.5 Mapping of the Information Exchange Model to DNP3 services The following services defined in 61400-25-3 shall be mapped to services defined in DNP3: – Data model (GetDataValue, SetDataValue) – Control model (Select, SelectWithValue, Operate, CommandTermination) The mapping to DNP3 provides services for the process data (signal) exchange only It is the intent of this mapping to use the services of DNP3 as they are No extensions of the definitions provided by DNP3 are intended E.6 Protocol stack details E.6.1 DNP3 DEVICE PROFILE DOCUMENT Minimum implementation for compatibility with IEC 61400-25 shall have a device profile that permits the selections shown in this clause and Table E.6.1 Compatible devices may support any other options in

(normative) Time synchronization F.1 General Any implementation claiming conformance to this part of IEC 61400-25 and declaring support for objects containing an attribute of type TIMESTAMP shall use the SNTP protocol as a minimum in order to guarantee the synchronism inside the wind power plant The use of other more precise synchronisation protocols is not within the scope of this part of IEC 61400-25 In order to get the same interpretation of the TimeQuality attribute of the TIMESTAMP, the following rules should apply: – On the device start-up, its ClockNotSynchronized flag shall be set to TRUE until the device synchronises with an external SNTP server or another more precise synchronisation source (for example GPS, PTP or IRIG-B) – If no other more accurate external synchronism source exists and the SNTP server does not reply to the synchronisation requests or the SNTP responses arrive with the LI indicator indicating that the TimeServer is not reliable, the ClockNotSynchronized flag shall be set after an specific timeout defined by the vendor, in the Protocol Implementation eXtra Information for Testing (PIXIT) document This timeout depends on the precision of the internal clock and shall guarantee a specified maximum deviation (PIXIT) – If the TimeStamp information cannot be considered valid due to, for example, a failure in the internal clock, the ClockFailure flag shall be raised – A value TRUE for the TimeQuality attributes ClockNotSynchronized or ClockFailure, indicating that the timestamp is invalid, shall remain set for all data objects containing the TIMESTAMP attribute until the clock has been succesfully synchronized F.2 A-Profile The A-Profile for Time Sync Services shall be as defined in 6.5.1 of IEC 61850-8-1:2004 F.3 T-Profile The T-Profile for Time Sync Services shall be as defined in 6.5.2 of IEC 61850-8-1:2004 BS EN 61400-25-4:2008 61400-25-4 © IEC:2008(E) – 237 – Annex G (informative) Interfaces – Implementation considerations G.1 General To give some guidance in the understanding of the IEC 61400-25 series of standards, the following discussion of an example is intended to show what the IEC 61400-25 series of standards covers compared with a real system The IEC 61400-25 series of standards does not constrain any implementation of the information, service models, communication stacks, actions, and application program interfaces (APIs) NOTE The example is not representative Many other possible interfaces on both sides are possible G.2 Example interfaces of a real system The information exchange between a wind power plant (WPP) device and supervisory and control systems mainly comprises – according to Figure G.1 – a client, a server, several interfaces, and actions The server (WPP server) represents the information and information exchange models The client (WPP client) represents the complementary to the server For example, a service provided by the server can be requested by the client The client itself is not specified (it mainly provides the complementary roles of the server) The complete chain from a source of information up to a SCADA visualisation is described (from right to left in the figure): – The data value source is the real WPP The exchange of data (raw) values between the real WPP process and the WPP server is realised by the interface (IF1) and (IF2) – these interfaces are implementation specific How many interfaces are implemented at the server side is implementation specific – The WPP server adds useful information to the (raw) process data (e.g., hierarchical name, time stamp, quality, etc.) This is defined in the model and the addition of the name etc is defined as the action (Act1) – this action is implementation specific – The model of the information (as it is seen from the network point of view) is defined by IEC 61400-25-2 – the model realisation is implementation specific – Monitoring of value changes of process data values delivered from the real-time data source is represented by (Act1) – this action is implementation specific, but behaviour and services are defined in IEC 61400-25-3 – Exchange of data values between WPP server and supervisory and control systems via (IF3) – the behaviour and services are defined in this part of IEC 61400-25 – Exchange of the model description located in the server with another system (IF3) – the behaviour and services are defined in this part of IEC 61400-25 – Exchange of data values between (communication) client and client application (visualisation, HMI) via (IF4) and (Act2) – this action is implementation specific BS EN 61400-25-4:2008 61400-25-4 © IEC:2008(E) – 238 – DLL e.g., visualize at HMI Model/ behavior Act2 IF3 SCADA Visualization HMI TCP/IP

(IF3) is the only interface that is defined by the IEC 61400-25 series of standards This interface (IF3) is defined by the information that is accessible through this interface and by the messages
