28、CATION OF TERMINALS WITHIN A SYSTEM 1 Scope This International Standard establishes general principles for the identification of terminals of objects within a system, applicable to all technical areas (for example mechanical engineering, electrical engineering, construction engineering, process engi

29、neering). They can be used for systems based on different technologies or for systems combining several technologies. Requirements for marking of terminal designations on products are not part of this publication. NOTE The standard is based on the general principles for the structuring of systems in

30、cluding structuring of the information about systems, established in the International Standard ISO/IEC 81346 series, published jointly by IEC and ISO. 2 Normative references The following referenced documents are indispensable for the application of this document.

31、tion cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

34、ted in a process of development, implementation, usage and disposal NOTE 1 The object may refer to a physical or non-physical “thing”, i.e. anything that might exist, exists or did exist. NOTE 2 The object has information associated to it IEC 81346-1, definition 3.1 BS EN 61666:2010 6 61666 IEC:2010

35、 3.2 system set of interrelated objects considered in a defined context as a whole and separated from their environment NOTE 1 A system is generally defined with the view of achieving a given objective, e.g. by performing a definite function. NOTE 2 Elements of a system may be natural or man-made ma

36、terial objects, as well as modes of thinking and the results thereof (e.g. forms of organisation, mathematical methods, programming languages). NOTE 3 The system is considered to be separated from the environment and from the other external systems by an imaginary surface, which cuts the links betwe

37、en them and the system. NOTE 4 The term “system” should be qualified when it is not clear from the context to what it refers, e.g. control system, colorimetric system, system of units, transmission system. NOTE 5 When a system is part of another system, it may be considered as an object as defined i

38、n this standard.

41、al network BS EN 61666:201061666 IEC:2010 7 NOTE 1 The connection may refer to: a) a physical interface between conductors and/or contacts, or piping and/or duct systems to provide a signal, energy or material flow path; b) an association of functional nature established between logical elements, so

42、ftware modules, etc. for conveying information. NOTE 2 The external networks may be of different nature and accordingly they may be classified. IEC 81714-3 provides such classifications. 3.10 terminal designation identifier of a terminal with respect to the object to which it belongs, related to one

43、 defined aspect 3.11 terminal designation set group of terminal designations, each identifying the same terminal from different aspects 3.12 object designation identifier of a specific object in a given context NOTE Examples of such designations are: reference designation, type number, serial number

44、, name. IEC 61355, 3.13 4 Terminal designation 4.1 General Terminals establish the interface of objects for connecting them to other objects in a network, for example connecting to an electrical network, logic function network, logic network in software, piping network, etc. An object may be associa

45、ted with any number of terminals. Each terminal shall be unambiguously identified with respect to the object itself as well as to the system to which this object belongs. Figure 1 illustrates the principle of constructing an unambiguous terminal designation. Figure 1 Principle of terminal designatio

46、n IEC 1956/10 BS EN 61666:2010 8 61666 IEC:2010 The terminal designation shall consist of the terminal marking as defined by the manufacturer or designer of the object used as component in the system or of the identifier as defined in the documentation of the object. If it is necessary to indicate t

47、he aspect of the terminal that the terminal designation relates to (for example within human readable presentations), the terminal designation shall be preceded by a prefix sign identifying the aspect. NOTE 1 This prefix sign will exist in addition to the separator sign. NOTE 2 The prefix sign is co

48、nsidered to be part of the terminal designation. The terminal designation shall be formed according to 4.2, 4.3, or 4.4. The terminal designation shall be presented, in documentation, in accordance with IEC 61082-1. The object designation shall unambiguously identify the object to which a terminal i

49、s assigned. This implies that an object designation shall be (or be made) unambiguous in a specified context, i. e. within the considered network. NOTE 3 This requirement can be fulfilled by reference designations in accordance with IEC 81346-1 and such designations are therefore used in the following text. 4.2 Designation of terminals with respect to the product aspect A terminal designation provided with respect to the product aspect shall
