The Embedded World trade fair, held in Nuremberg, Germany has become the world’s largest show for the embedded community. While the embedded market is fragmented into thousands of different application areas, the focus on automation has grown in recent years, as the IIoT is picking up pace and automation suppliers put more and more intelligence into their field and edge devices.

Increasingly, this approach is now entering the traditionally conservative automation industry and was discussed in depth at the fair.
