Siemens runs Profinet over 5G for industrial communication
Siemens has developed a technique to run the Profinet industrial protocol in real time via a private 5G network.
The move is part of infrastructure being developed by Siemens for private 5G networks where the company has a deal with chip supplier Qualcomm.
Siemens is developing its own 5G ecosystem, which consists of a 5G infrastructure for private 5G networks and end devices. The 5G infrastructure is under development and will be available in 2023.

The VXLAN (Virtual Extensible LAN) transmission technology developed by Siemens for its Scalance 5G routers and security appliances embeds the Profinet IO protocol, which is transmitted in Layer 2, into Layer 3 packets. This allows the packets to be transmitted across network boundaries.
As the 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. With a private 5G network, this means no local controls have to be used on the individual AGVs, saving cost and reducing maintenance requirements.
Siemens is also demonstrating the connection of automated guided vehicles via 5G in a prototype of a private industrial standalone 5G network at the Hannover Fair. This is using the Scalance MUM853-1 industrial 5G router for the control cabinet, connecting local industrial applications with public 5G and 4G (LTE) mobile networks. With the router, plants, machines, controls and other industrial devices can be monitored and maintained remotely via a public mobile network at high data rates. In addition, the device can be integrated into private 5G networks.
Companies can test their applications in a prototype of a private Industrial 5G standalone test network based on Release 15 of 5G from the 3GPP standards group at the fair. This is an industrial 5G network that uses the spectrum for campus networks available in Germany (3.7 – 3.8 GHz band). 3GPP has frozen the Release 17 specification and is working on Release 18.
Industrial ICT company HMS Networks has integrated sensors into the infrastructure via a controller and a 5G router. “The integration of our devices into the Siemens network was very easy,” says Dr. Jens Jakobsen, Head of Development at HMS Labs.
“Within Siemens’ private 5G network, we will be demonstrating at the Hannover Messe how our industrial 5G router can now also transmit security-relevant signals via mobile communications. Commissioning our 5G router within the Siemens network was particularly easy,” said Frank Hakemeyer, Director Communication Interfaces at Phoenix Contact.
