4.5.2 Features and technical data
The device can be directly integrated in an AS interface network is parameterized in its factory settings
so that the most frequently used AS-i functionality is available immediately. Only adaptations for
application-specific functions of the device or the bus system, the addressing and proper connection of
the supply, BUS, sensor and actuator cables need to be carried out.
