BSI DD IEC/PAS 62026-7:2009 2010

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.
