GB/71921S—2003/1S0/TR13283:1998 This standard is a technical document equivalent to 1S0/TR133;i Industrial Automation Time-limited Communication System Architecture Time-limited Communication System Application Requirements Network Intelligent Management. 1S0, TR13283:1938 is formulated by 1S/1C184/SC5WG2* "Internet of Things and Interconnection" Working Group. TC184//W has set up a special task force to study the requirements of time-limited communication system architecture, especially the requirements of time-limited communication system. Automation 1 is to use the network to work in a distributed environment. In this application scenario, the communication system must have the general performance of the network and should also have the performance to solve various types of time-limited communication systems under harsh conditions. In In such systems, time is a very important factor. Recently, fieldbus has been widely used in automation and control systems. There must be an intermediate network between the MA and the fieldbus network: this network should ensure accurate data transmission (especially good time information), support operation under abnormal conditions, and achieve efficient data transmission under limited information requirements. It should also support various forces to achieve resilience. Proposing this ultimate demand and establishing a theoretical method to meet it is the purpose of the formulation of a guiding technical document. This guiding technical document is a technical standard for the leading edge of industrial automation. The purpose and basis of this guiding technical document have been explained in the introduction. The main contents of this guiding technical document include Chapter 1: Specification, which includes: Terms and definitions; Chapter 2: User flow of the system; Chapter 3: QoS requirements for network management in TA; Chapter 4: QoS model of CNN; Chapter 5: QoS characteristics of TCA; Chapter 6: QoS capabilities in NM; Chapter 7: Methods and mechanisms of ICA networks; Appendix
With the development of the standard and the actual needs of the Chinese people, the national standard has become a greater technical and economic policy for China. The new foreign advanced standards have become a greater technical and economic policy for China. This new guiding technical document adopts 150/1R13283:1S98 to formulate China's national standard. The formulation of the text follows the original formula, and the technical content is basically the same as the ISR3: standard. The difference is that the abbreviations in the text must be omitted. In order to facilitate the reading and use of the standard, the overall format follows GB/11·Catalytic Work Part 1: Standard Construction Knowledge Writing. In the current standard, some minor details are added in the referenced standard in the zero chapter of the standard.
In order to make the standard as the standard, the original technical document was modified and the details of 150>/TR13383:1I98 were retained. This technical document has important implications for promoting the standardization of American manufacturing and improving the system standards of enterprises. The appendix of this guidance technical document is a normative guidance document issued by the machinery industry. This guidance technical document is mainly issued by: Beijing Machinery Industry Automation Research Institute. This guidance technical document is also the main document of the National Automation System Standardization Technical Committee. The main drafters of this guidance technical document are: Xiaodong Po, Wenjuan Wei, Fen Xu, and Hu Bang: GB/3.19219-2003/IS0/TR13283:1998 ISO Foreword IS (International Standardization Organization) is a joint organization of international national standards bodies (members of ISU). The work of preparing international standards is usually done by a technical committee. Each member country with an interest in the subject established by the technical committee has the right to participate in the work. International organizations with which it has a cooperative relationship, both official and non-governmental organizations, also participate in these works: [S] cooperates closely with the International Electrotechnical Commission (EC) in all aspects of electrotechnical standardization. The main task of the S technical committee is to prepare international standards. Under certain circumstances, the technical committee may propose to publish a technical report in any of the following forms:
.… The first form is that after repeated efforts, the publication of international standards still does not receive the necessary support: - The first form is when the subject is still in technical development or, due to other reasons, it is possible to reach an international standard in the future rather than now.
A third form is when a technical report has been collected from international standards published to date of the same type of validity (e.g. "latest developments").
Technical reports of the first and second forms should be reviewed within three years of publication to determine whether they are valid or not. Technical reports of the first form do not need to be reviewed until the data they provide are deemed no longer valid. Technical reports of the second form were prepared by ISO/TR-32 Technical Committee 1S0/TC184 (Industrial Automation Systems and Design) Subcommittee S5 on Automation and Communications.
It is obvious that in this form. 1) The standard is not suitable for time-limited communications. The standardized network structure is currently mainly used for communication and does not provide the corresponding performance and adaptability for time-limited communication, especially when time-limited non-time-limited communications exist. In many CIM and fieldbus systems, an intermediate network is required between the common enterprise-wide medical network (MAP) and the fieldbus network. This intermediate network should be able to carry large amounts of data and time-sensitive information, and be able to operate across long distances and in hostile environments. To this end, a special group was established under I5O/TC1R4/SC:/WG2 to study the requirements for the architecture of a time-sensitive communication system. The requirements for the intermediate network were considered, and a technical report was presented to address the requirements for time-sensitive communication within the fieldbus. Where the communication system must adhere to specified time windows, some of the requirements must be considered when managing time-sensitive communication networks. The second part of this technical report is the management and support of these requirements, and Figure 1 shows the relationship to other standards.
Time-critical Network Management (TCNM) defines only the requirements necessary to manage a TCCS network and does not describe aspects of system management related to configuration management, accounting, security and incident management, unless there are special requirements for time-critical support, which means that the support of TCM will have a significant impact on the overall performance of the TCM service and will also have an impact on other areas of the time-critical service to perform its functions.
The main focus of this technical report is to provide a close integration of the information requirements of the control system and the management and support of these requirements. This work will complement the work done on the Plant Information Network (MAP), which has the advantage of having a large storage component and a large package service capability between the information processor (small computer) and the control processor dedicated controller. This work will also complement the work done on sensor networks (fieldbuses), primarily to provide a less complex interface for simple plant-level sensors, actuators and other equipment. There is no clear definition of whether the communication system should be wired or non-wired: if certain requirements are met, both solutions may work. However, some requirements may be met by only one solution while others are required. Since MMS is a wired-oriented layer, the networking and communication capabilities are particularly wired, and the overall service can also be wired: GB/Z.19219—2003/1SO/TR13283:1998 This technical report highlights the user requirements for the wired communication system identified by the Task Group and briefly summarizes the requirements. It also provides suggestions for the management and support of these requirements. The good system of the time-consuming and good quality of the system is the user's cost requirement. The system lacks the time-consuming and exhaustive theory. The basic theory of ODF is the basic theory of teaching and sales theory. The result is the dynamic structure of GB/TS7, and the high demand of the safety + children's festival printing is the use of the service to gather the more quality of the whole quality for the iron plus mechanism.

Time-critical Communication System (TCCS) is a communication network system that is suitable for communication with dynamic changes in the order and communication mode of a network system; however, this communication network also supports certain state tracking. Time-critical communication is communication with a specific bounded time window, within which a certain node or action must be completed. TCS provides the ability to coexist with time-critical information, using cross-network data control architecture in distributed time-critical application systems. This distribution is only possible if the communication system provides a certain quality of service, especially with regard to inter-state constraints and cabinet equality. It is important to note that all core systems are independent of other network systems in terms of adaptability requirements. The tighter the constraints, the more flexibility becomes a medical requirement, because if the data is not disturbed by the smallest amount of interference, it will take a lot of effort to meet the network requirements of the time constraints:
TCC architecture should follow SI Huaben conversion when necessary to meet the pressure requirements determined in Chapter 6. The current OSI standards cannot adapt to the time-limited source information because they are originally designed to ensure universal data transmission or meet the internal communication requirements of information format delivery. Therefore, the current model and system architecture need to be modified to support industrial C. The user requirements of TCCS
white automation: The factory uses the network rate for the distributed control application. This industry requires that the communication system can not only meet the normal operation, but also adapt to the worst-case operation. In this system, time is very important. The network should be able to realize the transmission of large amounts of data and the transmission of the total after the time limit. At the same time, it should also support various methods to achieve adaptability. If necessary, a migration table can easily connect TCCS and the installed T" data communication network: F-to operate in a very harsh environment, it requires a highly reliable interface and simulation and transmission method, so it must have very low bit rates and a small amount of medium modem. Users should be able to explore the advantages of communication The network management system can allocate resources, control the access direction of other work groups, discover potential faults, and other confirmed user needs. The reading window should be realized in the SI: Figure 2 shows the relationship between the TCC system structure, the uniformity, or scalability, and the time required for communication and the underlying system environment. The network capacity of TCCA can be converted from the user needs of the CS to meet the time-limited communication network. Some service plans are formulated to meet the time-limited communication network requirements under the dynamic changes of the system. From the perspective of the basic architecture, the QoS requirements can be expressed as part of the network management requirements. When the QoS requirements are transmitted between service entities, they can be expressed as part of the mechanism through QoS: these values ​​are closely related to the strategy used for the operation of the time-limited communication network system. In these time-limited applications, all the requirements may not be met. Therefore, for the network management in a TCCA or a CCA, not all the network management requirements specified must be met. This can be divided into several categories, and the specific examples that meet these requirements are not discussed in this technical report. c

GB/7.19219—2003/TS0/TR13283;1998 Industrial Automation Time-Limited Communication Architecture| |tt||User requirements and network management for time-critical communication systems This standardization technical guide presents the user requirements for the network management of time-critical communication systems that support multiple applications in peer-to-peer or multi-peer communication. This technical guide uses the concepts and terminology of the QoS framework developed by ISO/IEC 11001/1:1994/WT to translate the user requirements of systems supporting time-critical communication into QoS requirements for networks supporting time-critical communication. This technical guide also presents models, comfort and functionality for network management within time-critical communication systems. This guidance technical document is aimed at time-limited communication systems for discrete parts manufacturing applications, however, this time-limited communication system can also be used in other occasions, including process control. If this guidance technical document focuses on time-limited communication systems for event-driven applications, in which the information flow of the source signal and the network configuration change dynamically, this guidance technical document can also be used for state-driven applications, in which the communication mode and configuration are static.
