IEC/PAS 62026-7:2009(E) 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 PAS establishes requirements for the interchangeability of components with such interfaces. It specifies the following particular requirements for CompoNet^TM:
- 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.
