AS-Interface (AS-i) provides you with an effective and powerful bus system which connects the sensors and actuators on the lowest field level with the superior control – with unrivaled ease, safety and integration! AS-Interface serves as a cost-favorable feeder for PROFINET or another higher-level fieldbus system. As an alternative, you can plug in a central AS-i communication module directly next to the SIMATIC controller. AS-interface is easy to configure in TIA Portal and standardized as an open standard in accordance with IEC 62026-2. All components comply with the AS-i specification and are correspondingly tested and certified.

AS-i Standard and AS-i Safety
Fast and flexible installation of the AS-i I/O modules by simply plugging them onto the bus line
