Title Low-voltage switchgear and controlgear - Controller-device interfaces (CDIs) - Part 3: DeviceNet
Project Number 20888
Abstract/Scope This part of IEC 62026 specifies an interface system between single or multiple controllers, and control circuit devices or switching elements. The interface system uses two twisted shielded conductor pairs within one cable - one of these pairs provides a differential communication medium and the other pair provides power to the devices. This part establishes requirements for the interchangeability of components with such interfaces. This second edition of IEC 62026-3 cancels and replaces the first edition published in 2000. This second edition constitutes a technical revision. The main changes with respect to the previous edition are listed below: - addition of new services to the base messaging protocol in 5.2; - replacement of detailed application layer requirements in former annexes by references in 5.3 to corresponding specifications in the new edition of IEC 61158 (2007); - addition of requirements for a corresponding safety protocol in 5.6 (by reference to IEC 61784 3); - modified presentation of cable and connector specifications in 8.2 and 8.4, and addition of a new type; - addition of references for safety tests for both EMC and logical tests in 8.10 and 9.3).

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn

(6) This list of normative references is purely indicative. The only official list of normative reference is the list of the published standard.
