36、rastructure is similar to that of other utilities such as heating, lighting and electricity supplies. As with other utilities, interruptions to service can have serious impact. Poor quality of service due to lack of planning, use of inappropriate components, incorrect installation, poor administrati

37、on or inadequate support can threaten an organisations effectiveness. Historically, the cabling within premises comprised both application-specific and multipurpose networks. Standards within the EN 50173 series have enabled a controlled migration to generic cabling (with an associated reduction in

38、the use of application-specific cabling) and supported the development of high data rate applications based upon defined cabling models. This European Standard, EN 50173-3, recognizes the benefit of generic cabling to interconnect several pieces of apparatus within industrial premises (within and be

39、tween structures and buildings) and is to be read in conjunction with EN 50173-1. This European Standard provides, for industrial premises: a) users with an application independent generic cabling system and an open market for cabling components; b) requirements for infrastructures that support crit

40、ical automation, process control and monitoring applications in a range of industrial environments; c) users with a flexible cabling scheme such that modifications are both easy and economical; d) building professionals (for example, architects), production and control engineers with guidance allowi

41、ng the accommodation of cabling both before specific requirements are known, i.e. in the initial planning either for construction or refurbishment, and for further deployment as the requirements of specific industrial areas are defined; e) industry and standardisation bodies with a cabling system wh

42、ich supports current products and provides a basis for future product development and applications standardisation. This European Standard specifies multi-vendor cabling, and is related to: - the associated standard covering general requirements for generic cabling within premises (EN 50173-1); - st

43、andards for cabling components developed by Technical Committees of CENELEC and/or IEC; - standards for the quality assurance and installation of information technology cabling (series EN 50174) and testing of installed cabling (EN 50346); - applications developed by the technical bodies of IEC (inc

44、luding the subcommittees of ISO/IEC JTC 1), study groups of ITU-T and CENELEC TC 65CX “Fieldbus”. Within this European Standard the cabling, defined between the interfaces shown in Figure 1, contains passive components only. The applications listed in , Annex F, have been analysed to determine the r

45、equirements for a generic cabling system. These requirements, together with statistics concerning premises geography from different countries and the models described in Clause 6, have been used to develop the requirements for cabling components and to stipulate their arrangement into cabling system

46、s. As a result, generic cabling defined within this European Standard is targeted at, but not limited to, industrial premises. It is anticipated that the generic cabling system meeting the minimum requirements of this European Standard will have a life expectancy consistent with other infrastructure

47、s within industrial premises. BS EN 50173-3:2007+A1:2010EN 50173-3:2007+A1:2010 (E)EN 50173-1:2011 - 7 - Figure 1 shows the relationship of generic cabling to the OSI reference model.
