In the digitalisation of industrial processes, growing demands for energy efficiency, cybersecurity, and controllability are confronted with legacy technologies such as serial interfaces, proprietary bus systems, or installations that are difficult to scale. With Single Pair Ethernet (SPE), a new technology is emerging that addresses these challenges. But what exactly is SPE? What specific advantages does it offer manufacturers, mechanical engineers, and operators? And how can the transition to this future-oriented technology succeed? Single Pair Ethernet (SPE) is a new, globally rec
