IAS 2020 - Review

Astrid Wang, our colleague from China, reports on the IAS show: “In hall 5.1 at booth B126, AS-International presented its new ASi-5 technology, and attracted the interests of the visitors with its powerful performance and distinctive features. More than 400 brochures are distributed to the visitors, and 75 visitors left behind their contact information for further communication...


Video: AS-Interface und IO-Link

The german video gives a short overview of the advantages of the IO-Link connection with AS-Interface. AS-Interface reduces costs and makes IO-Link devices network-compatible. IO-Link is simply connected and supplied with power via AS-Interface. After rapid contact with the piercing technology, the data is ready for use in host sys-tems and cloud services.


Speed, ready for new automation tasks

The new technology ASi-5 is fast, ASi-5 is easy to connect, ASi-5 is the direct connection to the data highway. ASi-5 uses modern data communication. With OFDM technology the devices can communicate simultaneously by using different channels. Video language German

Communication on the racing line.

Successful communication always follows a clear path. AS-Interface takes this quite literally. It uses a single reverse polarity protected two-conductor cable, carrying power and data, to connect sensors and actuators to the control system of your automation network.

The advantages of AS-Interface

Compared to the typical parallel wiring, AS-Interface’s advantage is its low wiring efforts and reduced hardware deployment. The reliable piercing technology as well as the intuitive and flexible device connection result in a significantly faster installation. Additionally, the system offers easy configuration options, leading to reduced start-up efforts and - in case of system faults – guarantees fast diagnostics and trouble shooting.

In short: AS-Interface reduces costs, while simultaneously increasing system performance.
