1 Scope and object
This part of IEC 62026 specifies a method for communication between a single control device and switching
elements, and establishes a system for the interoperability of components with the
specified communication interfaces. The complete system is called “Actuator Sensor
interface (AS-i)”.
This standard describes a method for connecting switching elements, such as low-voltage
switchgear and controlgear, standardized within IEC 60947, and controlling devices. The method may also be applied for connecting other devices
and elements.
Where inputs and outputs I/O are described in this standard, their meaning is regarding
the master , the meaning regarding the application is the opposite.
The object of this standard is to specify the following requirements for control circuit
devices and switching elements:
– requirements for a transmission system and for interfaces between a slave , a master and electromechanical structures;
– requirements for a complete interoperability of different devices within any network,
when meeting this standard;
– requirements for an interchangeability of devices within a network, when fulfilling
the profiles of this standard;
– normal service conditions for th...
