Low-voltage switchgear and controlgear. Controller-device interfaces (CDIs) - CompoNet

DD IEC/PAS 62026-7:2009 Low-voltage switchgear and controlgear. Controller-device interfaces (CDIs). CompoNet

DD IEC/PAS 62026-7 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.

DD IEC/PAS 62026-7 establishes requirements for the interchangeability of components with such interfaces. It specifies the following particular requirements for CompoNetTM:

• 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.

CompoNetTM is intended for use in, but is not limited to, industrial automation applications. These applications may include devices such as limit switches, proximity sensors, electropneumatic valves, relays, motor starters, operator interface panels, analogue inputs, analogue outputs and controllers.
