AS-Interface – the clever field bus standard
AS-Interface (AS-i) provides you with an effective and powerful bus system which connects all 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 PROFIBUS and PROFINET and supports easy engineering. It is standardized in accordance with IEC 62026-2. All components comply with the AS-i Specification and are correspondingly tested and certified. The AS-i standard is manufacturer-neutral.
The right solution for each application:
AS-i supports perfect adjustability – to any system size and any safety requirement.
AS-Interface – the powerful system
The best choice for AS-i networks for universal application
The master, a power supply unit as well as various standard and safe stations (slaves) form the basis of every AS-i system. The master ensures data exchange with the slaves by means of cyclic polling. The AS-i power supply units supply the network's slaves and sensors with energy
AS-Interface networks can be connected to the SIMATIC controller, SINUMERIK, or other controllers in a very user-friendly way: With the CM AS-i Master ST module in the ET 200SP for connection to all controllers and for any plant size. With the AS-i master module on the S7-1200 Basic Controller for smaller automation solutions. Or with the other AS-i master modules from Siemens for other applications. The integration is just as easy as with other expansion modules of the SIMATIC controllers
Key data per AS-i network
•Number of slaves: up to 62
•Number of I/Os: up to 496 inputs and 496 outputs
•Topology: any, as line, star, tree
