CSN EN 62026-3 ed. 2 - Low-voltage switchgear and controlgear - Controller-device interfaces (CDIs) - Part 3: DeviceNet

EN 62026-3 ed. 2 Low-voltage switchgear and controlgear - Controller-device interfaces (CDIs) - Part 3: DeviceNet - 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.Original English text of CSN EN Standard.The price of the Standard included all amendments and correcturs.
