This standard specifies requirements for a bit-oriented interface system between a single controlling device and control circuit devices or switching elements as defined in EN 60947-1, connected by an unshielded, untwisted two-wire cable carrying data and power. It also enables the interchangeability of components which have such interfaces. This standard specifies: requirements for interfaces and for electromechanical structures for slaves and masters; performance of slaves, electromechanical structures and masters under normal service conditions; constructional and performance requirements; tests to verify conformance to the requirements. Specific requirements for the various profiles for slaves and masters are given in annexes A and B. NOTE 1: The standardized low-voltage switchgear and controlgear products covered by the EN 60947 series are: EN 60947-1: General rules; EN 60947-2: Circuit-breakers; EN 60947-3: Switches, disconnectors, switch-disconnectors and fuse-combination units; EN 60947-4:Contactors and motor-starters; EN 60947-5: Control-circuit devices and switching elements; EN 60947-6: Multiple function equipment; EN 60947-7: Ancillary equipment. NOTE 2: Where inputs and outputs (I/O) are described in this standard, their meaning is relative to the master. The meaning relative to the application is the opposite
