11、aintenance of reference data. 11 ISO 15926-1:2004(E) iv ISO 2004 All rights reserved Foreword ISO (the International Organization for Standardization) is a worldwide federation of national stan- dards bodies (ISO member bodies). The work of preparing International Standards is normally carried out t
12、hrough ISO technical committees. Each member body interested in a subject for which a techni- cal 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 col
13、laborates closely 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 S
14、tandards. Draft International Stan- dards 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. Attention is drawn to the possibility that some of the element
15、s of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 15926-1 was prepared by Technical Committee ISO/TC184, Industrial automation systems and integration, Subcommittee SC4, Industrial data. ISO 15926 consists of
16、the following parts, under the general title Industrial automation systems and integration Integration of life-cycle data for process plants including oil and gas production facili- ties: Part 1: Overview and fundamental principles Part 2: Data model ISO 15926-1:2004(E) ISO 2004 All rights reserved
17、v 0 Introduction 0.1 Background Information concerning the engineering, construction and operation of process plants is created, used and modified by many different organizations throughout a plants life. Economic, safety and envi- ronmental considerations demand that this information is available t
18、o owners and operators of facili- ties, contractors, and regulatory bodies in a consistent, integrated form. This requirement can be satis- fied by specifications that prescribe the structure and meaning of data that is shared by organizations and disciplines involved in all stages of a plants life-
19、cycle. The need to increase the cost efficiency of process plants is leading to business practices that depend on the efficient integration and sharing of plant information in a computer processable form. These business practices include the following. Many users needs now span more than one of th e
20、 traditional information views. Safety and envi- ronment are two examples of this. Concurrent engineering requires design work to progress in parallel, with the state of the design being available electronically, in computer processable form, to other engineering, planning, pur- chasing and logistic
21、al activities. Significant cost savings are expected from standardization of component specifications. The in- formation about these specifications is required in computer processable form for easy incorpora- tion into plant designs and requirements. In the past, hand-over of plant design informatio
22、n was often restricted to design drawings and pa- per documents. Use of this information in managing the operation and modification of the plant was restricted to manual processes, or the information had to be redefined in a format suitable to the required application. Having the plant design and eq
23、uipment information in computer proc- essable form increases the efficiency and effectiveness of the operational phase of the plant. Accurate computer processable information about a plants performance throughout its lifetime is of high value, for optimising future modifications to the plant and for
24、 designing new plants on the basis of experience with existing plants. By using a consistent context for data definitions, the information used in the various aspects of the plants life-cycle can be brought together. This allo ws information to be integrated, shared and ex- changed in a consistent,
25、computer processable form. 0.2 Purpose of ISO 15926 The purpose of this International Standard is to facilitate integration of data to support the life-cycle activities and processes of process plants. To do this, this International Standard specifies a data model that defines the meaning of the lif
26、e-cycle information in a single context supporting all the views that process engineers, equipment engineers, operators, maintenance engineers and other spe- cialists may have of the plant. Traditionally, data associated with a process plant have been concentrated on some individual view of the plan
27、t at a point in time. Such data are usually defined and maintained independently of other groups of users, resulting in duplicated and conflicting data that cannot be shared either within an en- terprise or with business partners of an enterprise.

28、0.3 Description of ISO 15926 ISO 15926 is an International Standard for the representation of process plant life-cycle information. This representation is specified by a generic, conceptual data model that is suitable as the basis for implementation in a shared database or data warehouse. The data m
29、odel is designed to be used in con- junction with reference data, i.e. standard instances that represent information common to a number of users, process plants, or both. The support for a specific life-cycle activity depends on the use of ap- propriate reference data in conjunction with the data mo
30、del. ISO 15926 is organized as a series of parts, each published separately. This part of ISO 15926 pro- vides an overview. It specifies the contents and functions of the different parts of ISO 15926 and the relationships between them, and describes: an overview of ISO 15926; the fundamental princip
31、les that are the basis of ISO 15926; the relationship of ISO 15926 to other industrial data standards; definitions of terms used throughout ISO 15926. 0.4 Typographical conventions The following typographical conventions are used in this International Standard. A numbered reference enclosed in brack
32、ets (for example, 2) is a reference to a document that is listed in the Bibliography. In this International Standard the same English language words may be used to refer to an object in the real world or to a concept, and as the name of an EXPRESS data type that represents this object or concept. Th
33、e following typographical convention is used to distinguish between these. If a word or phrase occurs in the same typeface as narrative text, the referent is the object or concept. If the word or phrase occurs in a bold typeface, the referent is the EXPRESS data type. Names of EXPRESS schemas also o
34、ccur in a bold typeface. The name of an EXPRESS data type may be used to refer to the data type itself, or to an instance of the data type. The distinction between these uses is normally clear from the context. If there is a like- lihood of ambiguity, the phrase entity data type or instance(s) of is
35、 included in the text. Double quotation marks denote quoted text. Single quotation marks denote particular text string values. Some components of this International Standard are available in electronic form. This access is pro- vided through the specification of Universal Resource Locators (URLs) th

38、 Industrial automation systems and integration Integration of life-cycle data for process plants including oil and gas production facilities Part 1: Overview and fundamental principles 1 Scope This International Standard specifies a representation of information associated with engineering, con- str
39、uction and operation of process plants. This representation supports: the information requirements of the process industries in all phases of a plants life-cycle; NOTE 1 The process industries include those involved in oil and gas production, refining, power generation, and manufacturing of chemical
40、s, pharmaceuticals, and food. sharing and integration of information amongst all parties involved in the plants life-cycle. The following are within the scope of ISO 15926: a generic, conceptual data model that supports representation of all life-cycle aspects of a process plant; reference data that
41、 represents information common to many process plants and users; scope and information requirements for additional reference data; methods for the analysis of requirements and development of reference data; procedures for registration and maintenance of reference data; templates for the exchange of
42、data used in a particular context and their mapping to the concep- tual data model; methods for the development of such templates and their mapping to the conceptual data model; conformance to the requirements of this International Standard. The scope of business activities that are supported by thi
43、s International Standard is illustrated in Figure 1, which shows the main activities and data flows associated with the life-cycle of a plant.

EXAMPLE A reference data library cover
46、ing technical data about process systems, electrical systems and instrumentation systems can support design, engineering and maintenance activities for these systems within a process plant. The following are outside the scope of ISO 15926: commercial, business, and administrative data that are not d
47、irectly related to the engineering, operation and maintenance of process plants. This International Standard is applicable to implementation of databases or data warehouses that en- able integration and sharing of data amongst different participants in the life-cycle of a process plant. The generic
48、data model specified in ISO 15926-2 provides a suitable conceptual data model for such a database or data warehouse. NOTE 4 See 5.2 for further information concerning the nature of conceptual data models. This part of ISO 15926 provides an overview of this International Standard. The scopes of the o
49、ther parts of ISO 15926 are defined within those parts. 2 Normative references The following referenced documents are indispensable for the application of this document.
