21、ntrol 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 range of physical, usage, information content and configuration requirements. The physical require
22、ments 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 technologies, there are common components, interfaces and environmental requirements that are specifi
23、ed 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 for a specific application. This standard simplifies the CDI selection process by providing a
24、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 the CDIs IEC standard identifies. Clause 9 contains the test specification. Standardization of
25、 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. For this standard to be complete and usable, it requires the availability of specific CDI stan
26、dards, which make up the other parts of the IEC 62026 series.

27、 General rules 1 Scope This International Standard 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 fi
28、eldbuses and are considered by IEC subcommittee 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 brough
29、t together in this part of IEC 62026. For each 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 speci
30、fic CDI part may omit a general requirement 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
31、 are given in the relevant product standards. 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.
