Siemens enables the transmission of Profinet IO via a private 5G network, which allows data to be transmitted in real time for industrial applications. This is made possible by the VXLAN (Virtual Extensible LAN) transmission technology in the Scalance 5G routers and security appliances from Siemens. VXLAN embeds the Profinet IO protocol, which is transmitted in Layer 2, into Layer 3 packets, which allows them to be transmitted across network boundaries. Since Layer 2 communication now takes place via 5G, a central controller can communicate with decentralized I/O modules on mobile devices such as automated guided vehicles (AGVs) via Profinet in a private 5G network and no local controls have to be used on the individual AGVs. This saves costs and reduces maintenance.
