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.
