12、 BS ISO 11783-5:2011ISO 11783-5:2011(E) iv ISO 2011 All rights reservedForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO techn
13、ical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
14、with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted 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 In
15、ternational Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. ISO 11783-5 was prepared by Technical Committee ISO/TC 23, Tractors and machinery
16、 for agriculture and forestry, Subcommittee SC 19, Agricultural electronics. This second edition cancels and replaces the first edition (ISO 11783-5:2001), which has been technically revised. It also incorporates the Technical Corrigendum ISO 11783-5:2001/Cor.1:2002. ISO 11783 consists of the follow
17、ing 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 Part 3: Data link layer Part 4: Network layer Part 5: Network management Part 6: Virtua

20、l equipment based on ISO 11898-11and ISO 11898-22. SAE J19393documents, 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 completed to allow electronic units that meet the truck
21、and bus SAE J1939 specifications to be used by agricultural and forestry equipment with minimal changes. This part of ISO 11783 is harmonized with SAE J1939/814. 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
22、on-board 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 m

26、:2011(E) ISO 2011 All rights reserved 1Tractors and machinery for agriculture and forestry Serial control and communications data network Part 5: Network management 1 Scope ISO 11783 as a whole specifies a serial data network for control and communications on forestry or agricultural tractors and mo
27、unted, semi-mounted, towed or self-propelled implements. Its purpose is to standardize the method and format of transfer of data between sensors, actuators, control elements and information storage and display units, whether mounted on, or part of, the tractor or implement. This part of ISO 11783 de
28、scribes the management of source addresses (SAs) for control functions (CFs) of electronic control units (ECUs), the association of addresses with the functional identification of a device and the detection and reporting of network-related errors. It also specifies procedures, and minimum requiremen

36、ion within the CF. 3.6 suspect parameter number SPN 19-bit number used to identify a particular element, component, or parameter associated with a CF NOTE Suspect parameter numbers are assigned to each individual parameter in a parameter group and to items that are relevant to diagnostics, but are n
37、ot a parameter in a parameter group. 4 Technical requirements 4.1 General Network management for an ISO 11783 network provides the definitions and procedures necessary to uniquely identify CFs on the network, manage the assignment of addresses and manage network errors. A CFs ability to select an ad
38、dress depends on the CFs address configuration capabilities as described in 4.2. Each CF shall be capable of providing its unique 64-bit NAME. The rules for creating this NAME, associating it with an address and giving the ability or non-ability to change that address are specified in 4.3. CFs shall
39、 successfully claim an address in accordance with the procedures detailed in 4.4 prior to sending any other messages on the network. Multiple CFs can work together to perform a function, provided each CF claims its own address following the rules in 4.4.2.3. BS ISO 11783-5:2011ISO 11783-5:2011(E) IS
40、O 2011 All rights reserved 3The inability to successfully claim an address in accordance with the procedure shall be handled and reported to the network following a standard method detailed in 4.4.2.4. Network initialization sequences associated with the address-claiming process are described in 4.5
41、. A set of physical requirements which extends the requirements of ISO 11783-2 is listed in 4.6. Where timeouts are not otherwise specified, the timeout defaults defined in ISO 11783-3 apply. 4.2 Address configuration capabilities 4.2.1 General Address configuration is the method by which a particul
42、ar CF determines the SA it will use for an address claim. For the purposes of the address-claiming process, there are two basic address configuration capabilities: non-configurable address and self-configurable address. These are distinguished by the value in the self-configurable address field in t
43、he most significant bit position in the CFs NAME. CFs conforming to ISO 11783 shall be self-configurable-address-capable. Non-configurable-address-capable CFs shall be tolerated on the network to allow compatibility with CFs conforming to the previous edition of this part of ISO 11783 and CFs confor
44、ming to SAE J1939. There are also two extended address configuration capabilities: command-configurable address and service-configurable address. A CF may implement one or more of the extended address configuration capabilities. 4.2.2 Non-configurable address A non-configurable address CF cannot cha
45、nge its initial address during the address-claiming process. If multiple non-configurable address CFs are claiming the same address, then only the CF with the highest-priority NAME can obtain the address. The others shall announce their inability to claim an address. The self-configurable address fi
46、eld is the most significant bit in the CFs NAME and therefore a non-configurable address CF always has higher priority than a self-configurable address CF. This implies that a non-configurable address CF forces a self-configurable address CF to claim another address. 4.2.3 Self-configurable address
47、A self-configurable address CF is one that can select its initial address based on proprietary algorithms and then claim that address. This CF, in cases of address conflict, is also able to re-calculate its address and re-claim (unless all 120 of the addresses between 128 and 247 are used). The valu
48、e in the self-configurable address field in the NAME (see 4.3.2) indicates whether or not a CF has this capability. The CF shall only change its initial address when it loses address arbitration, and it shall only use addresses in the range 128 to 247 inclusive. But if the CFs function is one that h
49、as an assigned preferred address, then it may also use the preferred address. 4.2.4 Service-configurable address A service-configurable address CF is one whose source address can be changed in the field by a service technician. The address can be altered by any one of a number of proprietary techniques or by using the commanded-address message, while in a “service” mode of operation. A service tool may be used for this operation. 4.2.5 Command-configurable address A command-
