A key technology in the digitalization of our world
Digitalization and the Industrial Internet of Things (IIoT) are driving the demand for faster, seamless networking in various industries. Ethernet has proven effective in intelligent device networking, but Single Pair Ethernet (SPE) will replace serial fieldbus communication protocols in the future. SPE’s innovative characteristics make it valuable for advanced communication infrastructures. Phoenix Contact offers cross-industry expertise and an ideal product portfolio for SPE implementation in various fields. Ethernet solutions typically require two wire pairs, but Gigabit Ethernet may require four for increased data transmission rates. Single Pair Ethernet, which works with a single wire pair, can transmit data and power simultaneously. Its transmission rates range from 10 Mbps at 1,000 meters to 1 Gbps at 40 meters, making it suitable for demanding tasks like networked sensor technology. This technology is suitable for fields previously affected by limitations in data rates, ranges, and seamless communication.
Connections of up to 1,000 meters
Standard Ethernet solutions have limitations, such as a maximum of a 100-meter point-to-point connection distance. Furthermore, To cover longer distances in industrial systems, additional repeaters or switches are needed. SPE technology allows devices to be connected over 1,000 meters with 10 Mbps transmission speed and Power over Data Line (PoDL) technology with only one cable, potentially replacing specific fieldbus technologies in the future.
Speeds of up to 1 Gbps and more
Single Pair Ethernet (SPE) is a reliable solution for complex network topologies with gateways, offering transmission speeds ranging from 10 Mbps to 1 Gbps. Hence, IEEE 802.3 consortia is discussing further SPE standards for higher data rates and distances which will open up the spectrum for SPE for even more fields of applications.
Seamless and secure data communication
Industrial systems, such as Ethernet networks and fieldbuses, are being replaced by more efficient communication systems due to the Industrial Internet of Things (IIoT), requiring seamless, secure data connections for applications.
Cost-effective factory automation
Factory data generation is increasing, necessitating continuous communication. The SPE ensures a consistent networking from sensors to the cloud, offering a simple, secure, compact, and cost-effective cabling solution for industrial applications. Eventually, SPE solutions will be cheaper in the future than current bus and Ethernet components.
SPE and robots: Space-saving and high-performance
SPE provides advantages for autonomous and collaborative robots, including higher data transmission rates, simplified cabling, with data and power in just one line. Hybrid solutions will also be available, providing data and power contacts in one connector. This reduces cables and connections, resulting in fewer fatigue errors, faster troubleshooting, and easier maintenance. Furthermore, SPE also optimizes robot-handling design with a lower bending radius compared to conventional automation cables.
Building automation: Real-time control with SPE
Intelligent buildings require continuous communication between IoT devices and the cloud for real-time data processing. Single Pair Ethernet (SPE) is ideal for bundling and forwarding data generated by a large number of applications, increasing connection density with the compact design of its components. The 10BASE-T1S standard allows multiple sensors to be connected in a line topology, enabling network connection of light, temperature, smoke, air, and window controllers. This unification of OT and IT on the same platform simplifies maintenance and reduces costs.
SPE as the basis for sustainable energy solutions
Intelligent data management is crucial for sustainable energy, especially in wind turbine generators and photovoltaic systems. Conventional copper-based Ethernet connections are not suitable for high-height connections, leading to the use of fiberglass or wireless solutions. Furthermore, Single Pair Ethernet can also be used for extended distances between key connection nodes in solar parks and power-to-grid systems.
Consistent, global data flow: Process automation and SPE
Process automation in the oil and gas sector requires remote control of large sites with consistent data flow. SPE can provide efficient network structures without intermediary devices, and Power over Data Line. (PoDL) offers simultaneous data and power transmission advantages.
Safe and efficient: Advanced Physical Layer (APL) technology based on SPE
APL is an SPE standard for automation, enabling high data and power transmission demands in explosion-protected areas. It uses IEEE 802.3cg’s 10BASE-T1L standard and IEC TS 60079-47, 2021-03 (2-WISE) standard, supporting explosion protection methods. APL bridges large distances, interoperability, and data acquisition for predictive maintenance. It provides efficient network structuring and cost-effective modernization for the oil, gas, and chemicals sectors. With the integration of existing cabling and Ethernet protocols such as EtherNet/IP™, HART-IP, OPC UA, and PROFINET
