One of the greatest challenges industry currently faces is making logistics and production systems more flexible. In order to accomplish this purpose, it is necessary to have sensors, actuators and other automation components located on movable subsystems. Tools on robot arms, slide rails, rotary tables and coordinate tables are examples of such subsystems. They typically need to be connected to the overall control system in a way that ensures very short cycle times. Nowadays cable drag chains, rotary feedthroughs and slide contacts are used for this purpose but have significant drawbacks. For instance, they are heavy, are subject to wear and tear, limit the motion trajectories of the subsystems, restrict the number of attachable automation components, and hinder the retrofitting or the addition of future extensions. Through wireless connectivity it becomes possible to achieve greater flexibility in the production, as well as to increase process quality through the use of additional sensors and actuators, which are wirelessly integrated into the assembly. Moreover, the realization of new novel use cases like the next generation of human-robot collaboration will only be possible with wireless communication systems. Especially ultra-reliable real-time capable radio technologies (like URLLC) with cycle times of less than 1ms will be required for realizing the vision of the smart factory with fluid production. In this contribution, the innovative Ultra Low Latency Wireless Industrial Network (UWIN) – which Fraunhofer IIS is currently raising to product level in the projects IoT-COMMs [1] and IC4F [2], is presented. The UWIN communication system can be used as a wireless extension or as an equivalent replacement for wired fieldbuses for the transmission of industrial Ethernet protocols like Profinet or EtherCAT. UWIN can adapt to various frequency bands and focuses on the use license free frequency bands. Key performance indicators are isochronous cycle times of 125 µs, telegram size up to 35 Byte and packet error rate < 10-6. The presentation will provide a comparison between other relevant wireless real-time communication technologies with focus on ongoing activities of standards developing organizations like 3GPP (RAN 1 – Working item URLLC), ETSI (DECT Working group URLLC) and IEEE (801.11be towards extremely high throughput).
