Housing dimensions of the ASI MA IL UNI AS-i master in mm
The AS-i master is used to integrate the AS-Interface system into an Inline station and
connects AS-i to a higher-level network. The primary task of the AS-i master for Inline is to
transmit bits from the higher-level network to the AS-i slaves (actuators) and bits from
AS-i (sensors) to the higher-level network.
On one side, the AS-i master for Inline is controlled by the higher-level master, i.e., it is a
slave device in the network.
On the other side, it is the AS-i master, i.e., it monitors the connected AS-i system and
controls all processes on it.
The processes on both sides are executed independently of one another:
• The information from the process data channel of the Inline Modular local bus is
buffered in the AS-i master for Inline until it can be transmitted to the corresponding ASi
slave.
• The latest available information from all AS-i slaves is forwarded in one local bus cycle
to the Inline master via the process data channel.

Startup
The AS-i master enables complete startup and diagnostics of the AS-i system. Startup,
troubleshooting, and configuration on AS-Interface can be carried out directly on the device
using the two buttons, a display, and LEDs.
