AS-Interface Network
Actuator-Sensor-Interface, abbreviated AS-Interface
The can be connected to the AS-Interface network using the AS-Interface master module (FC4A-AS62M).
MicroSmart
AS-Interface is a type of field bus that is primarily intended to be used to control sensors and actuators. AS-Interface is a
network system that is compatible with the IEC62026 standard and is not proprietary to any one manufacturer. A master
device can communicate with slave devices such as sensors, actuators, and remote I/Os, using digital and analog signals
transmitted over the AS-Interface bus.
The AS-Interface system is comprised of the following three major components:
• One master, such as the
• One or more slave devices, such as sensors, actuators, switches, and indicators
• Dedicated 30V DC AS-Interface power supply (26.5 to 31.6V DC)
These components are connected using a two-core cable for both data transmission and AS-Interface power supply. AS-
Interface employs a simple yet efficient wiring system and features automatic slave address assignment function, while
installation and maintenance are also very easy.
For details about AS-Interface communication, see see page 2-57 and chapter 28.
