It also specifies procedures for initialization of network-connected ECUs.

ISO 11783 specifies a serial data network for control and communications on forestry or agricultural tractors and mounted, 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. ISO 11783 also provides an open interconnect system for on-board electronic systems used by agriculture and forestry equipment. It is intended to enable electronic control units (ECUs) to communicate with each other, providing a standardized system. This document defines and describes the network's 250 kbit/s, twisted, non-shielded, quad-cable physical layer and an alternative cable and architecture named twisted pair physical layer (TPPL) based on a 250 kbit/s, un-shielded, twisted pair cable network layer which is fully backward compatible to twisted quad based machines and devices. NOTE Where not differently specified, requirements are valid for both twisted quad and TPPL.

This document specifies principles for the design of highly automated aspects of highly automated machines and vehicles (e.g. agricultural tractors, tractor implement systems, implements and self-propelled machinery) during agricultural field operations. In addition, it provides guidance on the type of information on safe working practices (including information about residual risks) to be provided by the manufacturer. The purpose of this document is to assist in the provision of safety requirements, means of verification and information for use to ensure an appropriate level of safety for agricultural and forestry tractors and self-propelled machines with functions allowing highly automated operations (see 3.7). This document deals with all the significant hazards, hazardous situations and events (as listed in Annex A), relevant to agricultural and forestry tractors and self-propelled machines allowing highly automated field operations when used as intended and under the conditions of misuse foreseeable by the manufacturer during normal operation and service. NOTE 1 While this document gives principles for the design, verification, validation and provision of information for use of a highly automated agricultural machine (HAAM), the detailed specification of requirements for a specific application will be dependent on the machine and its operating conditions. Therefore, the principles for design given in this document need to be extended for specific HAAM by the use of relevant specific (type-C) standards, when available, or by the manufacturer of the machine using risk assessment. Such additional specification of requirements, for design, verification, validation or information for use are outside the scope of this document. NOTE 2 Safety requirements for specific machines not related to their highly automated operations can be available in machine-specific type-C standards. This document is not applicable to: — forestry applications; — mobile, semi-mobile or stationary machinery used for farm yard or barn operations; — operations on public roads including relevant requirements for braking and steering systems. NOTE 3 With respect to implements (e.g. their specific design, functions) and the communication between tractors and implements, additional risks can be relevant and can require additional measures. Such additional measures are outside the scope of this document and are the responsibility of the manufacturer. This document is not applicable to agricultural and forestry tractors, tractor implement systems, implements and self-propelled machines which are manufactured before the date of its publication.

This document specifies the application, the network layer protocols and the mapping to the controller area network (CAN) data link layer protocol as specified in ISO 11898-1. The application layer specifies protocol data units (PDU), which can be mapped to Classical CAN data frames using the Classical Extended Frame Format (CEFF). For PDUs exceeding the length of the CEFF-formatted data frames, this document specifies transport layer protocols and the mapping to CEFF-formatted data frames.

This document describes a universal virtual terminal that can be used by both tractors and implements.

ISO 14223-3:2018 describes the information that is stored in the advanced transponder memory, its format and the procedures for accessing such information. This document defines two parts of memory: a) the fixed part (mandatory): ISO 11785 data field; Data_Config field; b) the user part (optional): field of fixed allocation for defined data; uses an Object Identifier for data field separation in order to have maximum flexibility for future requirements.

ISO 11783-1:2017 as a whole specifies a serial data network for control and communications on forestry or agricultural tractors and mounted, 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. It is intended to provide open system interconnect (OSI) for electronic systems used by agricultural and forestry equipment. This part of ISO 11783 gives a general overview of ISO 11783. For ISO 11783 application developers, the content of this electronic database provides the current listing of the ISO 11783‑1 address assignments, identity assignments, and parameter definitions which have been assigned and which are officially registered by SAE J1939. This information is found in the online database on the ISOBUS website (http://www.isobus.net/).

ISO 16230-1:2015 is applicable to tractors and self-propelled ride-on machines, mounted implements, and towed implements used in agriculture and forestry. This part of ISO 16230 specifies general requirements that relate to the protection and safety of operators and bystanders on machines with on-board voltages in the range of 50 V AC to 1000 V AC and 75 V DC to 1500 V DC. This part of ISO 16230 applies to electrical equipment and parts of the electrical equipment on such machines and includes general requirements related to the protection and safety of operators, bystanders, and first responders. ISO 16230-1:2015 deals with significant hazards, hazardous situations, and events, as listed in Annex A, relevant to this agricultural machinery when used as intended and under the conditions of misuse foreseeable by the manufacturer during normal operation and service. ISO 16230-1:2015 is not applicable to the following: - specific design elements of external interfaces (e.g. the interface between a tractor and implement); - externally powered equipment (e.g. line powered equipment, equipment without on-board power generation); - purpose built forestry machines; - stationary electrical generators. ISO 16230-1:2015 is not applicable to machines which are manufactured before the date of its publication.

ISO 11783 as a whole specifies a serial data network for control and communications on forestry or agricultural tractors and mounted, 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. ISO 11783-10:2015 describes the task controller applications layer, which defines the requirements and services needed for communicating between the task controller (TC) and electronic control units. The data format to communicate with the farm-management computer, the calculations required for control, and the message format sent to the control function are defined in ISO 11783-10:2015.

ISO 15639-1:2015 of the injection sites of animal species is related to different species and several fields of interest. After decades of market experience, migration of the transponder is still a problem in most animal species being identified by injectable transponders. Migration is related to several factors. The major issues are the injection site and the application of the injectable transponder but the correct injection site can be dictated by the dimensions (length and diameter) of the injectable transponder. In dogs and cats, this is not a big issue as the transponders used are the smallest readily available. There are several publications which precisely describe the application of injectable transponders anatomically but there is a demand from the community to have a comprehensive overview of all aspects related to the application and use of injectable transponders for different animal species.

ISO 11783 as a whole specifies a serial data network for control and communications on forestry or agricultural tractors and mounted, 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. ISO 11783-7:2015 describes the implement messages application layer of the network, specifying the message set and defining the messages used for communication with and between tractors and connected implements.

ISO 24631-5:2014 specifies rules and procedures for verifying the capability of RFID transceivers of reading transponders used in individual animal identification complying to ISO 11784 and ISO 11785. In addition, ISO 24631-5:2014 specifies how to apply for an approval and the rights and duties to use this approval. ISO 24631-5:2014 does not set out the procedures for evaluating wireless synchronised mobile transceivers and also this document contains no provision for evaluating wired synchronisation of stationary transceivers. This test differs from ISO 24631‑2, which is intended for testing transceivers with all mandatory features described in ISO 11784 and ISO 11785. The test described here is intended for cost-effective non-synchronising transceivers that are capable of reading transponders complying to ISO 11784 and ISO 11785 but have no synchronisation capability and does not have to support the dual adaptive protocol. Furthermore, the activation field frequency accuracy is more relaxed.

ISO 11783 as a whole specifies a serial data network for control and communications on forestry or agricultural tractors, mounted, 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, information storage and display units whether mounted, or part of the tractor or any implement. ISO 11783-14:2013 specifies a sequence control system, such as a headland management system, which includes tractor and implement functions in one system. The system allows recording of multiple sequences of operator-activated functions from a tractor or any other control function on the ISO 11783 network, and replaying them on operator command.

ISO 24631-7:2012 specifies rules and procedures for synchronizing RFID transceivers while reading transponders used in individual animal identification complying to ISO 11784 and ISO 11785. The synchronization scheme described herein may be fully implemented within each reader, and such readers when attached to the synchronization bus create a peer-to-peer network (all readers are equal ? there is no dedicated master). Additionally, a cluster of readers, which could be in a master/slave configuration, may also be added to the bus using a dedicated, manufacturer specific Synchronization Interface. The Synchronization Interface presents to the synchronization bus electrical characteristics identical to those of a single peer-to-peer reader. The transceiver conformance standard ISO 24631-2 permits activation on/off timing tolerances of −0/+1 ms and therefore gives reader manufacturers options as to their preferred method for detecting the HDX header; partial or full. However, when synchronizing readers, irrespective of which header detection method is used, it is critical that all readers adhere strictly to the specific timings and timing tolerances as given in the timing diagrams. Particular attention should also be given to fault diagnostics which becomes more important when a reader network comprises products from different manufacturers. The obvious case is where a reader which is part of a network has become detached e.g. sync cable break, and it considers it's self to be now standalone and thus permitted to operate asynchronously to the detriment of all other readers.

ISO 12188-2:2012 specifies the process for evaluating and reporting the performance of agricultural vehicles equipped with automated guidance systems based on a global navigation satellite system (GNSS) when operating in an automatic steering mode. The main performance criterion is the lateral deviation of a representative point on the vehicle from a desired trajectory for that point. This performance criterion integrates the uncertainties associated with the performance of all components of the vehicle guidance system including the positioning device(s), automated steering components, and vehicle mechanisms and dynamics. ISO 12188-2:2012 focuses on steady-state tracking performance of the automated guidance system while travelling on straight paths over a level surface.

Its purpose is to standardize the method and format of transfer of data between sensor, actuators, control elements and information storage and display units, whether mounted on, or part of, the tractor or implement. ISO 11783-4:2011 describes the network layer, which defines the requirements and services needed for communication between control functions (CFs) in different segments of the ISO 11783 network. The various types of network interconnection units are defined in ISO 11783-4:2011.

ISO 14223-2:2010 specifies the code and command structure between the transceiver and the advanced transponder used in the radiofrequency identification of animals, this specification being fully backwards-compatible with those of ISO 11784 and ISO 11785. As a direct extension of ISO 11785, it is intended to be used in conjunction with that International Standard.

ISO 12188-1:2010 provides a procedure for evaluating and reporting the accuracy of navigation data determined using positioning devices that are based on GPS, GLONASS, Galileo or similar global navigation satellite systems (GNSS). It focuses on the performance of the positioning devices while they are subject to motions typical of ground-based agricultural field operations and specifies common performance parameters that can be used to quantify and compare the dynamic performance of different positioning devices.

ISO 10975:2009 specifies safety requirements for auto-guidance systems used in agricultural tractors and self-propelled agricultural machines. It is applicable to auto-guidance systems which are factory installed as an integral part of the tractor or self-propelled machine as well as systems designed to be retrofitted to equipment after such equipment has left the control of the manufacturer. It is not applicable to guidance systems used in tractors or self-propelled machines that do not require an on-board operator for primary control of the tractor or self-propelled machine. ISO 10975:2009 does not specify requirements necessary to ensure the integrity of the complex electronic control system which can be an integral part of the auto-guidance system. Such requirements are dealt with in other International Standards which address complex electrical/electronic vehicle control systems.

ISO 17532:2007 specifies a protocol for the automatic and interactive communication and control of computer systems used in livestock production. It supports communication within the livestock production as well as across the Internet.

ISO 11783-8:2006 specifies a serial data network for control and communications on forestry or agricultural tractors, mounted, semi-mounted, towed or self-propelled implements. Its purpose is to standardize the method and format of transfer of data between sensor, actuators, control elements, information storage and display units whether mounted or part of the tractor, or any implements. ISO 11783-8:2005 describes the messages required by tractors and self-propelled implements.
