AS-i and AS-i V2 buses are field buses (level 0) and can be used to connect sensors/actuators. They allow "Discrete" type information to be routed between a bus master and sensor/actuator slaves. The AS-i V2 bus also allows for routing of analog information.
AS-i and AS-i V2 buses are made up of three major basic components:
The main types of sensors/actuators
-
Communication sensors/actuators:
With a built-in AS-i function they link up directly to the AS-i bus via a passive distributor or a T-piece connection.
-
Conventional and IP65 sensors/actuators:
They connect to the bus via an AS-i interface (active distributor or Telefast IP20 discrete input-output bus interface). These interfaces are used to connect conventional sensors and actuators to the AS-i bus and provide them with capacity for dialog on the bus.
Illustration:
You can only connect standard slaves to the AS-i bus.
You can connect standard slaves and extended slaves to the AS-i V2 bus.
