Applies to interfaces between low-voltage switchgear and controlgear and controllers, including industrial CDIs for control systems, factory and process automation, specifies an interface system between a single controller or multiple controllers, and control circuit devices or switching elements and establishes requirements for the interchangeability of components with such interfaces. This Standard is identical with and has been reproduced from IEC 62026-3:2000.

This International Standard specifies an interface system between a single controller 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 standard specifies the following particular requirements for DeviceNet:– requirements for interfaces between controllers and switching elements;– normal service conditions for devices;– constructional and performance requirements;– tests to verify conformance to requirements.These particular requirements apply in addition to the general requirements of IEC 62026-1.
