AS-International: ASi-5 specification now available

During the general meeting mid-December 2019 in Gelnhausen, Germany, the project managers of the ASi-5 development collaboration, Dr. Thomas Sebastiany and Bernhard Wiedemann, officially handed the ASi-5 specification over to AS-International. The specification is now available to all members.

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.
