18、 multiple listeners Ship systems interconnection Documentation and test requirements FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to
19、promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Gui
20、des (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC
21、 also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as p
22、ossible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense.
23、 While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undert
24、ake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to
25、indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents inclu
26、ding individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or relia
27、nce upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the el
28、ements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. IEC 61162-402 has been prepared by Technical Committee 80: Maritime navigation and radiocommunication equipment and systems. The text of this standard
29、is based on the following documents: FDIS Report on voting 80/411/FDIS 80/421/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table.

35、IGITAL INTERFACES Part 402: Multiple talkers and multiple listeners Ship systems interconnection Documentation and test requirements 1 Scope 1.1 General This standard series, IEC 61162-400 and upwards, specifies a communication protocol for use in integrated ship systems. It also specifies an interf
36、ace description language for use together with the protocol, a set of rules for the use of this language and a set of standard interfaces described in the language. This part of the standard specifies a minimum set of tests to be done, test results to be achieved and documents that shall be availabl
37、e for all implementations of general protocol software and applications that are compliant with the IEC 61162-4 standard. Although this set of standard documents is collectively referred to as IEC 61162-4, the actual part numbers are in the 400-series (see 1.4 of IEC 61162-400). 1.2 Limitations in s
38、cope The tests and documentation requirements do not cover electrical, physical or environmental requirements that may apply to the use of software or computers onboard ships. Such requirements may be covered by IEC 60945 or IEC 60092-504. Other standards may also be applicable. This standard does n
39、ot necessarily cover all requirements from classification societies or other authorities. It is the responsibility of the user of this standard to ensure that all appropriate regulations are addressed. This standard contains tests to check that an application using the IEC 61162-4 protocol adheres t
40、o its advertised interface specification. These tests cannot guarantee the correct functionality of that application beyond the possibility of connecting it to the network and with a limited degree of accuracy in the messages transferred. This standard does not cover the system in which the IEC 6116
41、2-4 communication standard is used. Additional requirements will normally apply to the total system configuration. Fundamental requirements relating to ensuring reliable and timely transfer of data across data communication links are included in other standards associated with the integration of equ
42、ipment such as IEC 60092-504 and IEC 61209. This standard does not contain tests to verify compliance with these requirements. In addition, specific equipment related standards may also contain requirements for correctness and timeliness of data transmissions. Neither does this standard contain any
43、tests to verify such requirements. Thus, results from tests carried out in accordance with this standard cannot be used to demonstrate compliance with the requirements of any other standards for system or equipment functionality. -,-,- 61162-402 IEC:2005(E) 7 1.3 Limitations in test coverage The tes
44、t plan only specifies general tests of the protocols and a limited set of other general properties (black box tests). The test procedures will not generally cover tests of operating systems, communication libraries or other software components that are used to implement the standard. Neither does th
45、is standard specify any tests related to the way the system is implemented (white or glass box testing). 1.4 Limitations in degree of detail The test procedures are general in nature and do not generally specify detailed test programs and procedures. The procedures specify a minimum set of functiona
46、l aspects that need to be tested, with, in some cases, a minimum required set of excitations and corresponding required responses. The testers must develop the detailed procedures and test tools themselves. 2 Normative references The following referenced documents are indispensable for the applicati
