How SPE is driving the digital transformation<\/strong><\/h2>\n\n\n\n

Single Pair Ethernet (SPE) has the potential to transform industrial communication by enabling efficient, cost\u2011effective data transmission over long distances using just one wire pair. As its importance grows, the technology is advancing quickly, supported by progress in standardization, expanded connection technology options, and a unified pin connector pattern for factory automation.<\/p>\n\n\n\n

\"Teaming<\/a><\/figure>\n\n\n\n\n\n\n\n

The current status of standardization<\/strong><\/p>\n\n\n\n

Single Pair Ethernet transmits data over a single copper wire pair, reducing both cost and space. It supports multiple communication standards, delivering speeds from 10 Mbps over 1,000 m to 25 Gbps over 11 m.<\/p>\n\n\n\n

This makes SPE highly versatile and ideal for factory automation and other industrial applications. Its physical properties are defined by IEEE standards.<\/p>\n\n\n\n

\"The<\/figure>
\n

Standardization for SPE starts with IEEE 802.3, with various working groups defining its communication standards. Current standards cover multiple applications and speeds, while two upcoming ones\u201410BASE\u2011T1M (DA group) and 100BASE\u2011T1L (DG group)\u2014are expected in 2026 and will be key for future industrial communication.<\/p>\n<\/div><\/div>\n\n\n\n

The 10BASE\u2011T1M standard extends the existing 10BASE\u2011T1S multidrop standard, increasing range, node count, and enabling shared line transmission (MPoE). The new 100BASE\u2011T1L point\u2011to\u2011point standard will boost 100 Mbps SPE transmission distance from 40 m to 500 m, allowing SPE to cover the classic 100 m Fast Ethernet range in the future.<\/p>\n\n\n\n

Challenges during implementation<\/strong><\/h2>\n\n\n\n

Implementing SPE in industrial applications presents challenges that market players must address.<\/p>\n\n\n\n

Standardization and interoperability<\/strong>: Although standardization has advanced, additional standards still need to be developed and adopted to ensure full interoperability across manufacturers and devices. Different interpretations of existing standards can still cause compatibility issues.<\/p>\n\n\n\n

Infrastructure and cabling<\/strong>: Switching to SPE requires adapting existing infrastructure, which can involve significant cost and effort, especially in large or complex systems. While existing cabling can potentially be reused, its suitability for SPE must be assessed individually.<\/p>\n\n\n\n

Reliability and robustness<\/strong>: SPE components must operate reliably in harsh industrial environments, requiring high mechanical stability and resistance to vibrations, moisture, and temperature fluctuations. Developing and testing such robust components is both time\u2011consuming and costly.<\/p>\n\n\n\n

Security<\/strong>: Security is crucial for SPE. It must maintain data integrity and confidentiality, requiring appropriate security protocols and mechanisms. Ethernet already provides the necessary security foundation and offers clear advantages over outdated bus systems.<\/p>\n\n\n\n

Training and knowledge transfer<\/strong>: Technicians and engineers must be trained in the new technology to implement and maintain it effectively, requiring investment in training and knowledge transfer. However, many outdated fieldbuses can be replaced by SPE, eliminating the need to train new staff on legacy systems.<\/p>\n\n\n\n

Market acceptance<\/strong>: Market acceptance of SPE remains a challenge. Companies must be convinced of its benefits, and it may take time before SPE becomes an industry\u2011wide standard.<\/p>\n\n\n\n

Costs: <\/strong>Although SPE can deliver long\u2011term savings, it requires an initial investment in new components and infrastructure. Companies must weigh costs against benefits and consider the value SPE offers now and in the future.<\/p>\n\n\n\n

Despite these challenges, SPE offers significant advantages for industrial communication. With ongoing progress in standardization, robust component development, and workforce training, these obstacles can be overcome and the full benefits of SPE realized.<\/p>\n\n\n\n

The new face of SPE<\/strong><\/h2>\n\n\n\n

A standardized pin connector pattern is crucial for SPE in factory automation, enabling simple and flexible device connections. Phoenix Contact plays a leading role in developing and promoting this standard through close cooperation with industry partners, user organizations, and standardization bodies. Significant progress has already been made, and broad agreement on a unified pin connector pattern is now within reach. The IEC 63171\u20117 standard\u2014currently in its second edition with Phoenix Contact heavily involved\u2014defines the mechanical requirements for SPE connectors and forms the basis for this standardization. It ensures high mechanical stability, reliability, and easy handling. Many manufacturers have already announced plans to certify their first devices soon.<\/p>\n\n\n\n

Added value of SPE based on specific use cases<\/strong><\/h2>\n\n\n\n

SPE will play a key role in networking machines, sensors, and actuators in smart factories. Its long\u2011distance, highly reliable data transmission makes it ideal for factory automation. Beyond factory and automotive applications, SPE also offers benefits for many other industries.<\/p>\n\n\n\n

Building automation<\/strong><\/h2>\n\n\n\n
\n

Networked buildings increase efficiency, security, and convenience. With a standardized end\u2011to\u2011end IP protocol, devices such as sensors, switches, and thermostats can connect seamlessly to building management systems via the local network and the cloud. SPE enables flexible, energy\u2011efficient lighting control, precise HVAC monitoring, and reliable, fast data transmission for security systems like surveillance cameras, access control, and alarms.<\/p>\n<\/div>

\"End-to-end<\/figure><\/div>\n\n\n\n

SPE integrates various building control systems into the building management system, enabling centralized monitoring and control of all building technologies. It also supports efficient energy and load management by monitoring and optimizing energy use. Another example is the networking and control of elevator systems to improve maintenance and operational safety.<\/p>\n\n\n\n

The broad range of SPE standards enables support for many existing building\u2011technology use cases and paves the way for modernized communication systems.<\/p>\n\n\n\n

Renewable energies<\/strong><\/h2>\n\n\n\n

SPE also elevates networking and control in renewable energy systems. In wind turbines, it links sensors and control units for performance monitoring and optimized maintenance. In solar installations, it enables efficient data transmission between panels and inverters for precise system monitoring. With its extended range, SPE again offers an alternative to fiber\u2011optic cabling.<\/p>\n\n\n\n

In battery storage systems, SPE monitors charge and discharge states to maximize efficiency. In smart grids, it supports the integration of renewable energy sources and improves energy control and distribution. SPE is also used in EV charging stations, hydroelectric plants, and biogas facilities to network and control processes efficiently, always aiming to save energy and reduce costs.<\/p>\n\n\n\n
