The information models and information exchange services are interwoven.From a description point of view the two aspects are separated to some degree(see the excerpt shown in Figure 1).The common models (e.g.,LOGICAL-NODE and DATA classes including their services) are applied in part IEC 61850-7-4 and part IEC 61850-7-3 to define many specialised informa- tion models-the substation automation models.

NOTE 1 A server has two roles:to communicate with a client(most service models in IEC 61850 pro- vide communication with client devices)and to send information to peer devices (e.g.,for sampled values). b)LOGICAL-DEVICE (LD)-contains the information produced and consumed by a group of domain-specific application functions;functions are defined as LOGICAL-NODEs. c)LOGICAL-NODE (LN)-contains the information produced and consumed by a domain- specific application function,e.g.,overvoltage protection or circuit breaker. d) DATA-provide means to specify typed information,e.g.,position of a switch with quality information and timestamp,contained in LOGICAL-NODEs. Each of these information models is defined as a class.The classes comprise attributes and services.The conceptual class diagram of the ACSI is depicted in Figure 2. NOTE 2 The classes are major building blocks that provide the framework for substation automation device models.Additional details on the modelling and relations between part IEC 61850-7-4,IEC 61850-7-3.and this part of 61850-7-2 can be found in part IEC 61850-7-1. ⑤ Name 6 SERVER ObjectName ObjectReference △△△△ 1 ⑧/ LOGICAL-DEVICE ●1 1 ⑨ LOGICAL-NODE ●1 1.* 0 DATA 1. ⑩ DataAttribute Figure 2-Basic conceptual class model of the ACSI NOTE 3 The numbers in the circles point to the respective clauses in this part 2002-08-23:(16:30)
