32、389 D Page 7 EN 61334-4-1 : 1996 3 Description of the reference model 3.1 Introduction The specification of a communication system, such as an industrial local network or a set of interconnected subnetwork serves the following purpose: opening of the corresponding equipment to distributed applicatio

33、ns, giving official recognition to, and perpetuating, ongoing developments, implementing tools and structures for conformance testing in order to promote the interworking capability. The distribution line carrier transmission network fully justifies such a specification since this communication syst

34、em can be used for a large number of devices with various functions (station control unit, remote controlled feeder switch, meters, transformer station concentrators, portable input stations, lighting sources, automatic traffic lights at crossroads) which are manufactured by several competing suppli

35、ers. According to the rules in the field of telecommunication this specification should be comprehensive and unambiguous and should comply with the economic requirements of final applications. 3.2 Basic principles of the OSI model 3.2. I Layered architecture The purpose of the OS1 standardisation is

36、 the development of standardid telecommunication networks capable of supporting a wide range of heterogeneous equipment in order to form an “open system“. So that this heterogeneity may be possible, the OSI standards are restricted to the specification of the functions to be performed by each open s

37、ystem and of the protocols which are to be implemented between these systems. They avoid prescribing a particular mode for the achievement of the corresponding functions. Thus, the OS1 standards specify the behavior of open systems as a whole in their exchanges with other open systems and not their

38、internal operation. The conformity of a real system with the given specifications is based on the external view of its behavior during its exchanges with other systems. Among the different models for the organisation of activities, the OS1 has chosen the layered model and features seven layers: phys

39、ical layer, data link layer, network layer, transport layer, session layer, presentation layer and application layer.
