Introduction

The smooth progress of product data exchange, whether in the company, trading systems, engineering design tools or in the future control system (electrical, Measurement and control technology), are dependent on the exchange of information and the use of information have been made a clear definition.

In the past, when the user asked the supplier or the manufacturer for the quotation of the applicable device, they had a representation of the process control device and the system requirements Type can be said to be varied. And suppliers in the answer is usually based on their own file system, using different from the user's terms, structure and vector (paper files, databases, laser discs, electronic catalogs, etc.). Since the information of these devices is frequently in different information Technical system replication, such a dilemma often appear in the planning and design and follow-up process.

Any method that can record all of the data in the planning and ordering process and can be used in subsequent processes will cause the relevant Side of the high degree of concern, the prerequisite for the expression of the target and the standardization of data exchange.

IEC 61987-1 By defining the generic architecture of analog or digital output industrial process measurement and control device product attributes, the above goal has taken an important step. When the product moves from one party to the other, it helps to understand the product. This series of standards the first part applies to the catalog of paper products for process measurement and control devices provided by the product manufacturer.

The purpose of this section is to make process measurement and control devices more efficient. Ie the information contained in the IEC 61987-1 Equipment Product List and then add information about device operation and environmental requirements. The form used to describe and express these aspects should be applied to electrons Exchange and automatic processing.

In this section, the device is described in detail by creating a property table column (LOPs). These properties are compiled into the presentation device Specific attribute in the section. By compiling these sections, it is possible to produce a complete description of a particular device category or such device installation and a list of properties for running the environment information.

This section covers the following.

- It focuses primarily on the various attributes that can be used for business inquiry and quotation, in relation to planning and design, such as computer-aided engineering Design system (CAE), routine maintenance and enterprise resource planning system (ERP) and other business, because of its system process control System integration requirements, but also need to involve some of its detailed attributes.

- It provides a standardized method to help process control equipment and system suppliers and users both optimize their own company Internal and in the exchange of information with other companies when the work flow. According to the role in the project process, engineering design, procurement and Construction (EPC) The general contractor can be either a user or a supplier.

- It ensures that the information provided is clear and clear by its unquestionable data and structural representations.

It should also be noted that the component data dictionary has other uses, such as the production of spare parts list, it can also be used to generate the traditional rules the book.

Electronic data interchange layer.

Figure 1 The level of the electronic exchange process in this standard

This section describes the various levels of data exchange as follows (see Figure 1).

The dictionary layer. In order to achieve the standardization of all types of devices, distributed and general semantics, the standard defines a term for the capture, defined to and the relationship between devices used in the dictionary. It is based on the IEC industrial process measurement and control device component data dictionary, which uses IEC 61360-2 and ISO 13584-42. The proposed IEC 61987-11 will include the attributes and sections of the contents of the dictionary and so on. Other similar series of standards are defined in the various types of process measurement and control device properties list.

Note 1. The first version of the dictionary can not be all-encompassing, in the new technology applications and new devices appear, you can add a new device category.

Specification. The plant's process engineer can use a catalog of electronic specifications when planning a particular area. The content is from the group Data dictionary. Similarly, manufacturers of industrial process measurement devices, when making quotations that meet the conditions of the specification form, it produces the device, will have to be based on another specification form, its content also comes from this component data dictionary. In order to make a solution to the specification , The use of its base or polymorphism assessment method.

Message. The message generated by the product specification, including the sender, the receiver, and the transport protocol.

Note 2. The generation of messages is outside the scope of this standard.

Data exchange framework. Messages are sent from one business partner to other businesses through a data exchange framework. These messages can be used the format shown in Appendix C of this standard is sent in a conventional manner (eg e-mail, fax), or in an XML-based message distribution box Frame of the way to send.

Example. GB/T 19256 is an XML messaging framework.

This standard specifies the methods and mechanisms described in the creation of these specifications, which are required to compile meaningful data into the specifications of. Several aspects of the device are also the standardization of this standard. For example. one is about the device installation site environment, that is, process measurement the amount of equipment that should be operated under its conditions, and the other is how the device specifications meet the requirements of these conditions.

The component data dictionary contains the various attributes that can also be used for other purposes, such as the production unit required for administrative and commercial exchange the precise position or the way the control loop works. Similarly, more accurate engineering data, such as terminal or device tuning data authority , Or by adding a device specification or a supplemental device specification.

The specifications of the transaction data required to exchange electronic specifications between companies, as shown in the message layer of Figure 1, are beyond the scope of this standard Wai Nor does it specify a specific framework for its data exchange.

Each type of device is defined by a list of attributes (LOPs) that apply to such devices, which are information devices in different information technologies (IT) the basic requirements for the exchange between systems. The list of attributes supports enterprise-to-enterprise systems, as well as between systems within the organization, such as.

Computer-aided engineering (CAE) or enterprise resource planning management system (ERP). This standard also belongs to the device data the list of methods (LOP) is specified in the storage of process control systems or field devices.

Figure 2 An inter-firm support relationship created using a list of attributes

This part, IEC 61987-11 and more in more detail.

In order to facilitate the self-control engineering workflow, as well as user and supplier optimization, in the planning and post-maintenance of industrial installations the process and work flow, this part uses a list of structures for electrical and process control equipment (eg measuring devices, actuators, motors, low Pressure switch, etc.) to do a list of attributes.

The forthcoming IEC 61987-11 will contain a list of the properties of the commonly used measurement devices in the process industry.

A subsequent part of IEC 61987 has been planned and will contain a list of attributes for other device classes, such as actuator class or signal converter Category.

These attributes are themselves in the IEC component data dictionary, and their semantics and institutions follow the IEC 61360 and ISO 13584 series of standards Regulations.

Attributes and structured lists are topics that belong to different standards, respectively. This standard uses the IEC 61360 and ISO 13584 series of standards in the data model. This standard uses the IEC 61987-1 for the industrial process measurement equipment made the definition of the structure, but made it Some supplements and modifications are made so that the plates hold the contents of the device properties list (LOP).
