Material wear or a little carelessness on the shop floor: automated production can come to a standstill in a matter of seconds if wired communication lines to industrial robots unexpectedly fail. If this happens, the new "EchoRing Emergency Kit" can be used to create fully-fledged, radio-based substitute connections in no time at all - as the kit has successfully and impressively demonstrated over several months of use at the BMW Group Plant Leipzig.
When robots stop working because trailing cables or tool connections suddenly break down, the EchoRing Emergency Kit allows production to continue within a very short time. While EchoRing, as a bypass solution, ensures the transmission of production data, the causes of a cable malfunction can be fixed without hectic. If the fault can only be repaired during the next regular maintenance or if more extensive repairs are required, the EchoRing emergency kit guarantees the continued operation of the respective system even over longer periods of time.
BMW Group has been using the EchoRing Emergency Kit from R3 - Reliable Realtime Radio at its Leipzig production site for just over a year. Shortly after testing and evaluation in a robot test cell, the system was introduced into productive operation at BMW Group Plant Leipzig and also fulfilled higher requirements of complex robot systems.
The EchoRing Emergency Kit contains all the hardware components required for immediate bridging of defective cable routes via radio data transmission. These include "EchoRing Ethernet Bridges" together with the corresponding antennas and installation cables, device-specific adapter kits (e.g. for PROFINET communication) and individual accessories for mounting the EchoRing components on the respective robot. An optionally available tablet ("Health Monitor") allows quick and optimal configuration of the EchoRing radio network and enables the user to view information on the radio quality at any time or as required.
The scope of the solution provided can be individually adapted to customer-specific requirements. The EchoRing Emergency Kit is compatible with the robot systems used (e.g. ABB, FANUC, KUKA).
Although the provisional bridging is primarily intended for emergencies, the radio links set up can also be converted into permanent solutions if desired. EchoRing technology allows uRLLC-compliant data communication (ultra-reliable and low-latency communication) in the 5 GHz frequency band, making it a fully-fledged alternative to classic Ethernet or Industrial WLAN installations. Based on the Token Ring concept, EchoRing enables data radio connections with latency times of less than five milliseconds at transmission rates of 5 to 36 Mbit/s (depending on bandwidth and priority traffic).
Based in Berlin, R3 - Reliable Realtime Radio develops high-performance wireless industrial solutions. R3’s EchoRing protocol combines the reliability of a cable connection with the flexibility of a wireless network, ensuring latencies of under 5 milliseconds. The protocol is designed for a wide range of industrial machine-to-machine applications, up to and including critical safety protocols such as emergency stops. EchoRing’s expanding list of users includes industry leaders such as Wienerberger, Götting KG, and Kuka.
