scope:

This part of IEC 62026 specifies an interface system providing bit-level and word-level communication between a controller and control circuit devices such as sensors, actuators, and switching elements. The interface system uses cabling with round or flat profiles containing a two conductor signalling pair and optionally a two conductor power supply pair. This part establishes requirements for the interchangeability of components with such interfaces. This part of IEC 62026 specifies the following particular requirements for CompoNetTM 1): - requirements for interfaces between a controller and control circuit devices; - 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.
