This real-time Ethernet switch can be used to set up networks using the vendor-agnostic communication solution OPC UA over TSN. The TSN machine switch allows cycle times under 50 µs. It offers four real-time capable TSN ports and one standard Ethernet port—to connect a display, for example. The switch also opens up the possibility of star, tree or ring topologies in addition to daisy-chaining. Multiple switches can be cascaded to reach remote cabinets or implement large, complex real-time networks. Non-TSN nodes also can be incorporated in the network via the switch.
