GB/Z 19219-2003Industrial automation - Time-critical communications architectures - User requirements and network management for time-critical communications systems (English PDF)

1 Scope

This standard specifies: The system supports time communication systems systems and network management user needs.

This network management is the same for the same or equal to the communication between the application process or each application process time communication architecture -.

The standard use of ISO/IE, JTC1/SC21/WG7 developed-QoS basic framework concepts and terminology, would support time communication system user requirements converted into a communications network management and support time-QoS requirements.

This standard also describes the communication system within the time limit Network Management model, features and functions.

This standard is used for discrete parts manufacturing applications time communication system, however, these time communication system can also be applied to other occasions, including process control.

This standard focuses on event-driven applications time communication systems.

In such event-driven applications, communication information flow and network configuration changes dynamically.

Of course, This standard can also be used to state-driven applications, communication mode in this application and configuration are static -.

Foreword

About this edition

GB/Z 19219-2003 is the first edition of this standard. It was issued on 26 June 2003 and has been in force since 26 June 2003.

There is no earlier edition to compare it with, so a specification that has to refer to this subject can only cite GB/Z 19219-2003 itself.

The interval between issue and effect is the transition period. It exists so that producers, laboratories and buyers can requalify products, revise procedures and use up documentation before the new text becomes the one that applies. The date on this page is the official one from the record of the Standardization Administration.

Edition history and citation

GB/Z 19219-2003 is a first edition: there is no earlier version of this standard, so a document that needs to refer to this subject can only cite GB/Z 19219-2003 itself.

Where an edition is replaced, the Chinese standardization system keeps the number and changes the year: the number identifies the subject, the year identifies the text. That is why a citation without a year is ambiguous and a citation with one is not.

Classification and status

GB/Z 19219-2003 is classified under ICS 25.040.10, in the field of manufacturing engineering. ICS is the International Classification for Standards, the same scheme used by ISO and by the national bodies of most countries, which is what allows a Chinese standard to be placed beside its foreign counterparts on subject rather than on number.

Its Chinese Standard Classification code is CCS J 07. CCS is the domestic scheme, a letter for the sector and two digits for the subject within it, and it is the code by which the standard is filed and searched in China.

The GB/Z prefix marks a guiding technical document, which is a third category beside the mandatory GB and the recommended GB/T. It is issued when a subject is moving too fast, or is too varied in practice, to be settled in a standard: it records the direction the Chinese standardization system intends to take and the vocabulary it intends to use. It carries no compliance obligation and does not become binding when a contract cites it — which is also why GB/Z 19219-2003 is worth reading early, before the requirements it anticipates arrive as a standard.

The document is under the responsibility of the China Machinery Industry Federation, which is the body that maintains it and that will answer a formal question about its interpretation.

How this standard is designated

The full designation is GB/Z 19219-2003. A citation should carry the number with its year, because the year identifies the text that applies.

In a catalogue or a filing system it is found under ICS 25.040.10 and CCS J 07 — the international classification and the Chinese one, which are the two codes by which a standard on this subject is searched.
