DESCRIPTION

BS EN 62026-3:2015 - TC


This standard BS EN 62026-3:2015 - TC Tracked Changes. Low-voltage switchgear and controlgear. Controller-device interfaces (CDIs) is classified in these ICS categories:
  • 35.200 Interface and interconnection equipment
  • 29.130.20 Low voltage switchgear and controlgear
IEC 62026-3:2014 specifies an interface system between single or multiple controllers, and control circuit devices or switching elements. The interface system uses two 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 interoperability of components with such interfaces. This third edition of IEC 62026-3 cancels and replaces the second edition published in 2008. This third edition constitutes a technical revision. The main changes with respect to the previous edition are the followings:
- specification of group 4 messages (5.1.2);
- clarifications on messaging protocol (5.2);
- addition of I/O multicast poll messages (5.5.2 and 5.5.8);
- clarifications on slave behaviour (5.5.4 and 5.5.9);
- clarifications on physical layer (transceiver) in 5.7;
- miscellaneous corrections/clarifications on cable (8.2);
- clarifications on EMC testing (9.2.10) and logical testing (9.3). The contents of the corrigendum of March 2015 have been included in this copy.
