AS-Interface is a networking alternative to the hard wiring of field devices. It can be used as a partner network for higher level fieldbus networks such as Profibus, DeviceNet, Interbus and Industrial Ethernet, for whom it offers a low-cost remote I/O solution.

The “Association for Promoting Interfaces with Bus Capability for Binary Actuators and Sensors” (AS-i Association) is responsible for promoting the application and dissemination of the AS-i system; in particular the specification, standardization, certification and general user information.

Companies worldwide are relying on simple wiring and automation technologies to improve their overall plant efficiency and availability. Always present: AS-Interface. The sophisticated AS-Interface technology offers high reliability, noise immunity and diverse diagnostic capabilities.

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 higher-level controller – with unrivaled ease, safety and flexibility!

La definición clásica de AS-Interface es la de un bus maestro-esclavo, en el que un solo maestro controla hasta 62 esclavos. Cada esclavo puede transferir hasta cuatro entradas y cuatro salidas en un ciclo de bus. Además, proporciona un sistema de cableado único que es rápido, fácil de cablear y fácil de operar.

3 天之前 · An AS-i bus system is TÜV-certified up to Performance Level e, or PLe or Safety Integrity Level 3, or SIL 3. An advantage of ASIsafe is that components can be connected directly to the AS-Interface network, such as Emergency Stop pushbuttons, or safety door contacts.

AS-Interface, often abbreviated as AS-i, is a manufacturer-independent industrial networking standard connecting actuators and sensors of the first field level. It streamlines the integration of sensors and actuators with a control system. This AS-i bus system uses a two-wire flat cable to carry power and data.

2025年2月14日 · Welcome to AS-Interface, the efficient, easy, and worldwide standardized bus system for the lower field level.

2020年3月27日 · AS-Interface is a master-slave bus, with a single master controlling up to 62 slaves. It operates at the lowest level of the fieldbus hierarchy, but when implemented with an AS-I master/gateway (sometimes referred to as simply an AS-I gateway) it can connect to a higher-level network, such as DeviceNet, EtherNet/IP , PROFIBUS, or others.

AS-Interface enables cabling while freely choosing your topology. It replaces the complex, conventional parallel wiring. The cabling can be connected to control systems with different fieldbus systems (such as EtherNet/IP, Profibus-DP, Profinet, EtherCat etc.). How do you benefit from AS-Interface?
