11、a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represent
12、ed on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are dra
13、fted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International St
14、andard requires approval by at least 75 % of the member bodies casting a vote. ISO 11783-3 was prepared by Technical Committee ISO/TC 23, Tractors and machinery for agriculture and forestry, Subcommittee SC 19, Agricultural electronics. This second edition cancels and replaces the first edition (ISO
15、 11783-3:1998), which has been technically revised. ISO 11783 consists of the following parts, under the general title Tractors and machinery for agriculture and forestry Serial control and communications data network: Part 1: General standard for mobile data communication Part 2: Physical layer Par

17、nary Part 12: Diagnostics services Part 13: File server Sequence control is to form the subject of a future part 14.

18、specifies a communications system for agricultural equipment based on the CAN 2.0 B 1 protocol. SAE J 1939 documents1), on which parts of ISO 11783 are based, were developed jointly for use in truck and bus applications and for construction and agriculture applications. Joint documents were complete
19、d to allow electronic units that meet the truck and bus SAE J 1939 specifications to be used by agricultural and forestry equipment with minimal changes. General information on ISO 11783 is to be found in ISO 11783-1. The purpose of ISO 11783 is to provide an open, interconnected system for on-board
20、 electronic systems. It is intended to enable electronic control units (ECUs) to communicate with each other, providing a standardized system. The International Organization for Standardization (ISO) draws attention to the fact that it is claimed that compliance with this part of ISO 11783 may invol
21、ve the use of a patent concerning the controller area network (CAN) protocol referred to throughout the document. ISO takes no position concerning the evidence, validity and scope of this patent. The holder of this patent has assured ISO that he is willing to negotiate licences under reasonable and
22、non-discriminatory terms and conditions with applicants throughout the world. In this respect, the statement of the holder of this patent right is registered with ISO. Information may be obtained from: Robert Bosch GmbH Wernerstrasse 51 Postfach 30 02 20 D-70442 Stuttgart-Feuerbach Germany Attention
23、 is drawn to the possibility that some of the elements of this part of ISO 11783 may be the subject of patent rights other than those identified above. ISO shall not be held responsible for identifying any or all such patent rights. 1) Society of Automotive Engineers, Warrendale, PA, USA. BS ISO 117
