19、evice interfaces (CDIs) covered in this International Standard includes industrial CDIs for control systems, factory automation and process automation. Industrial CDIs have proliferated to meet specific user needs, but no single CDI meets all needs. The reason for multiple solutions is the wide rang

20、e of physical, usage, information content and configuration requirements. The physical requirements have resulted in CDIs with widely differing signal and line conditioning mechanisms in order to meet distance, node count and environmental considerations. While there is wide variation in CDI technol

21、ogies, there are common components, interfaces and environmental requirements that are specified by this standard. Standardized definitions of these common CDI requirements assist the user to compare and select technologies to match the distance, node count, throughout and installation requirements

22、for a specific application. This standard simplifies the CDI selection process by providing a common structure for generating a specific CDIs IEC standard while also allowing specific interface features and capabilities to be included. Clauses 1 to 8 contain the outline of general requirements that

23、the CDIs IEC standard identifies. Clause 9 contains the test specification. Standardization of CDI aspects also simplifies the task of writing the software for the higher layer functions of industrial control systems, such as supervisory control, operator interface and control strategy programming.

24、For this standard to be complete and usable, it requires the availability of specific CDI standards, which make up the other parts of the IEC 62026 series. EN 62026-1:2007 4 LOW-VOLTAGE SWITCHGEAR AND CONTROLGEAR CONTROLLER-DEVICE INTERFACES (CDIs) Part 1: General rules 1 Scope This International St

25、andard applies to interfaces between low-voltage switchgear, controlgear, and controllers (e.g. programmable controllers, personal computers, etc.). This standard does not apply to higher level industrial communication networks that have become known as fieldbuses and are considered by IEC subcommit

26、tee 65C. The purpose of this standard is to harmonize and define rules, components and requirements of a general nature applicable to industrial CDIs. Those features of the various CDI standards which can be considered as general have therefore been brought together in this part of IEC 62026. For ea

27、ch CDI, two main documents are necessary to determine all requirements and tests: a) this part, referred to as “IEC 62026-1” or “Part 1” in the relevant CDI parts covering the various types of CDIs; b) the specific CDI part of the IEC 62026 series. A specific CDI part may omit a general requirement

28、if it is not applicable, or it may add to it if it is inadequate in the particular case, but it should not deviate from the requirement unless there is substantial technical justification. NOTE Product-specific requirements for products incorporating a CDI are given in the relevant product standards

29、. These requirements apply in addition to those given in this International Standard. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of
