Products and Solutions For Single Pair Ethernet In Industrial Environments


Telegärtner, Phoenix Contact, Weidmüller, Reichle & De-Massari and Fluke Networks are developing mutually compatible components for Single Pair Ethernet

Steinenbronn - The companies Telegärtner, Phoenix Contact, Weidmüller, Reichle & De-Massari and Fluke Networks are presenting products and solutions for Single Pair Ethernet (SPE) in industrial environments at the SPS - Smart Production Solutions trade fair. These companies are developing and supporting the mating faces collectively added to the IEC 63171-2 (office environment) and IEC 63171-5 (industrial environment) standards. These standards define IP20 and IP65/67 mating faces for single- and four-pair data transmission in SPE applications. The companies in this partnership are pooling their technological expertise in order to ensure a standardised infrastructure for devices, connectors, cables and measurement technology. As they put it: “There’s no alternative to Single Pair Ethernet. It’s the key technology of the future and will enable end-to-end Ethernet-based communication in an unprecedented variety of application fields."  The purpose of SPE is not to define new higher transmission speeds or distances, rather, it is to form the framework for standardising reduced amounts of cabling for applications. This reduced cabling brings completely new areas of application into focus.

Data cabling with just one pair of wires enables transmission distances of up to 1000 metres at transmission rates ranging from 10 Mbps to 1 Gbps. This means that SPE is particularly well suited for infrastructure applications in machine building and systems manufacturing, process engineering, and also in building infrastructure. The main advantage is that SPE is environment-independent. Field devices, sensors, and actuators can be easily incorporated into the existing company-level Ethernet environment. There is no need for additional gateways or interfaces. SPE is allowing Ethernet to penetrate down to field level, thus making it more consistent, more efficient and more cost-effective than existing fieldbus systems.

Development of the Single Pair Ethernet began in the automotive industry, where the trend towards developing smaller and better performing devices is clear to see. Future-oriented technologies such as autonomous vehicles require a connection technology that enables the high-speed transmission of data with a very small structural footprint. Other industries can also benefit from this approach. “Single Pair Ethernet means a reduction in the amount of work for systems manufacturers. Compared to four-pair Ethernet, installation is easier and enables a noticeable reduction in space and weight,” explains Jörg Scheer, Director of the Device & Field Connectivity Division at Weidmüller. Simon Seereiner, Director of Product Management IE and SAI at Weidmüller, adds: “In new installations, users save on procurement costs and can design the necessary cable runs to be much more compact. The standardised mating faces also enable the efficient cabling of many communication devices that share a common line and interface. This means that users can continue to use the existing cabling and connect up to four devices, instead of just one.”

Thanks to the standardised interfaces, single- and four-pair cabling concepts can be combined with each other just as IP20 and IP6x solutions can. The two-wire technology also enables the application-specific supply of end devices with outputs of up to 60 Watts via the same pair of wires (Power over Data Line – PoDL). “Our collaboration in this standardisation will create security,” says Torsten Janwlecke, President Business Area Device Connectors at Phoenix Contact. “Throughout the world, users will be able to construct efficient network and cabling structures, from the sensors, through the control and company level, right through to the Cloud, all based on standardised interfaces.” Scheer adds: “Thanks to digitalisation, intelligent networking is increasing in every aspect of life. Consistent data transmission is also becoming ever more relevant in the industrial environment. Therefore, Ethernet cabling is already replacing many traditional fieldbus systems today.”

SPE significantly reduces the total cost of the network infrastructure. At the same time it creates a standardised, coordinated, open network for complete consistency within the network levels.

“The smaller footprint frees up space for more ports, especially at the nodes. This in turn achieves more efficient use of the infrastructure," explains Marcel Leonhard, Director of DataVoice at Telegärtner.

“Moreover, SPE will create new potential in various market segments such as factory and process automation, but also in transport and logistics due to the integration of new device technologies.”

“Certification of the installed Ethernet cabling is the most effective way to ensure correct operation. This is independent of the number of conductor pairs in the cable," says Mark Mullins, Global Communications Manager and co-founder of Fluke Networks. “In this way, customers can be sure that their investment in high-quality cabling and components is worthwhile. We have worked with over 30 standardisation committees to define the future of cabling since the company was founded. Our goal is to define effective standards that also allow the development of tools which customers can use to certify this exciting new technology and fix faults, if necessary.”
