Phoenix Contact, Weidmüller, Reichle & De-Massari (R&M), Fluke Networks, and Telegartner partner to create SPE System Alliance

The technology partnership between Phoenix Contact, Weidmuller, Reichle & De-Massari (R&M), Fluke Networks, and Telegartner for the Single Pair Ethernet (SPE) has progressed to create the SPE System Alliance. In this group, technology companies from various industries and fields of application have come together to bundle their respective SPE expertise and ensure the target-oriented exchange of this knowledge. The partners in this group are pursuing the goal of driving the development of SPE further forward for the Industrial Internet of Things (IIoT) and may branch out to other areas as well. The System Alliance has now also been joined by Datwyler, Kyland, Microchip Technology, Rosenberger, SICK, ORing, Draka/Prysmian Group, and University 4 Industry.

隨著單對以太網(SPE)技術的發展,菲尼克斯電氣、魏德米勒、R&M、福祿克網絡, 以及德力格能之間的技術合作不斷加強,并成立了SPE系統聯盟。該聯盟將來自不同行業和應用領域的領先技術公司聚集在一起,整合各自的SPE專業知識并針對性地開展交流。該聯盟的成員以追求推動SPE在工業物聯網(IIoT)以及相關領域的進一步發展為目標。目前,包括德特威勒、東土科技、微芯科技、羅森伯格、西克、威力工業網絡、Draka/Prysmian集團和University 4 Industry等公司也正式加入該聯盟。
The network aims to collaborate on the technological challenges faced when implementing SPE in IIoT applications. The goal of the companies is to accelerate their own development of expertise in SPE technology and to allow it to be implemented in their products.


Through this orientation toward a cross-industry and cross-application exchange platform, companies from all future SPE ecosystems are coming together. The focus is not, however, on individual aspects such as connection technology. Instead, the focus is on questions and challenges that continue to exist with many market participants in connection with SPE. Rule exchange formats and collaborative project activities provide the freedom for close cooperation. The members are already working together in the first sub-communities, in the fields of connection technology, standardization, SPE use-case reports, and even for cable solutions, among others.

Thanks to its lineup, the SPE System Alliance already covers a range of applications and fields of application:


Ethernet systems are being installed increasingly in the vehicle generations of today. Through the networking of control devices and sensors, further innovations in the fields of driver assistance systems such as LiDAR, high-resolution displays, autonomous driving, 4K cameras, and infotainment can be realized.


The development of the automobile Ethernet has led to the creation of two IEEE standards: 100BASE-T1 (100 Mbps based on BroadR-Reach technology) and 1000BASE-T1 (1 Gbps). Limit values for the connectors and cables and the associated measurement methods were defined from the demands on the overall channel. The partner company Rosenberger played a leading role in the standardization in both standard committees in the fields of automotive connector design, signal integrity, and EMC.

汽車以太網的發展推動兩個全新的IEEE標準的建立:100BASE-T1(基于BroadR-Reach技術的100 Mbps)和1000BASE-T1(1 Gbps)。根據對整個通道的要求定義了連接器和電纜的極限值以及相關的測量方法。合作伙伴羅森伯格在汽車連接器設計、信號完整性以及電池兼容測試的兩個標準委員會的標準化工作中發揮了領導作用。

The Internet of Things (IoT) allows smart buildings and factories to become a reality more easily and cost-effectively. With this IP protocol, LED lamps, switches, sensors, thermostats, machine control systems, and motors for window blinds are connected via the local data network and the cloud to the building management system. Application-specific fieldbus systems are no longer needed, meaning that gateways, complex interfaces, and different protocols are not necessary either. With the structured ceiling cabling (the Digital Ceiling), intelligent building automation can be combined via IP. This simplifies installation, maintenance, and network management. In most cases, high data rates are not needed, but a high connection density is. SPE is considered an ideal addition for the Digital Ceiling. The existing cabling infrastructure can easily be expanded with SPE for higher port density. Both, R&M and Telegärtner provide Digital Ceiling solutions and can show the implementation of SPE into such a system.

物聯網使智能建筑和工廠更容易、更經濟地成為現實。通過該IP協議,LED燈、開關、傳感器、恒溫器、機器控制系統以及百葉窗的電機等通過本地數據網絡和云連接到建筑管理系統。不再需要專用的現場總線系統,這意味無需網關、復雜的接口和不同的協議等等。借助數字化天花板(Digital Ceiling)的框架,智能樓宇控制系統就可以通過IP實現無縫連接。這簡化了安裝、維護和網絡運維。在大多數情況下,智能建筑不需要高速率傳輸,但需要高的連接密度。SPE被認為是數字化天花板的理想補充。SPE可以輕松擴展現有的布線基礎設施,以實現更高的端口密度。R&M和德力格能提供了數字化天花板解決方案,并且可以展示SPE在此類系統中的實施。

SPE provides consistent IP communication from the field level right through to the corporate level, and therefore from the sensor through to the cloud. Standardized pin connector patterns form the basis for the barrier-free networking of a wide range of components and devices. Phoenix Contact, Weidmuller, R&M, Rosenberger, and Telegärtner develop compact device and cable connectors in accordance with the standardized and fully compatible interfaces in accordance with IEC 63171-2 (IP20) and 63171-5 (IP67). The pin connector pattern can be integrated into all conventional and standardized connector versions (M8/M12) and enables efficient and future-proof cabling thanks to the high packing density and low space requirements.

SPE提供從現場層到企業層的一致IP通信,因此也可以提供從傳感器到云端的一致IP通信。標準化的引腳連接器模式構成了各種組件和設備無障礙聯網的基礎。菲尼克斯電氣、魏德米勒、R&M、羅森伯格和德力格能按照符合IEC 63171-2(IP20)和63171-5(IP67)的標準且完全兼容的接口開發緊湊型設備和電纜連接器。引腳連接器模式可以集成到所有傳統和標準連接器(M8/M12)中,并且由于緊湊和較小的空間要求,因此可以實現高效且面向未來的布線。

Now,in addition to their use in classic automation technology, sensors are increasingly being integrated as intelligent data suppliers into IIoT applications via Ethernet networks. Due to the miniaturization of the connection technology that has become possible with SPE, smaller and spatially limited sensors can also be connected to Ethernet networks.

An additional advantage is yielded by combining SPE with the power supply over the data line. This means that additional plug connections to the voltage supply are no longer needed. Moreover, the use of SPE as the standard interface allows device manufacturers to provide an optimized range of devices with fewer versions. Sensors in a machine or system can be cabled more easily and reduce the installation work for the user.

In SPE fields of application, the transmission channels are created from various cables and a varying number of plug connections. While the transmission channels are specified through transmission parameters such as bandwidth, attenuation, return loss, and shielding dimensions in the system standards (e.g., the ISO/IEC 11801 series of standards), the connectors and cables must then be tailored to the respective channel.

在SPE應用領域中,傳輸信道是由各種電纜和連接器組成。雖然在系統標準(例如ISO/IEC 11801系列標準)中通過傳輸參數(例如帶寬、衰減、回波損耗和防護尺寸)指定了傳輸通道,但是必須根據各自的通道量身定制連接器和電纜 。
The work being performed in the IEC46C committee is taking the lead here. Cables with a 20 MHz bandwidth for fixed routing, connecting cables suitable for the 10BaseT1 channels, and cables with a bandwidth of 600 MHz for 100BaseT1 and 1000BaseT1 are available (IEC 61156-11 series of standards and those following).

IEC46C委員會正在積極推進這項工作,固定路由帶寬為20 MHz的線纜,適用于10BaseT1的信號傳輸,帶寬為600 MHz的電纜適用于100BaseT1和1000BeT1的傳輸(IEC 61156-11系列標準及關聯標準)。

Along with the transmission of signals, the advantage lies in the simultaneous transmission of power along the single-pair cable, for example from the switch to the sensor. Known as PoE in the field of building cabling, the single-pair cable is called PoDL (Power over Data Line) here. Coordinated with the cross-sections and channel length, powers of up to approx. 15W can then be transmitted.

SPE的優勢實現了信號和電源同步傳輸,例如從開關到傳感器。在建筑布線領域被稱為PoE,在這里稱作單對電纜(PoDL,power over data line);跈M截面和線纜長度,傳輸的電能可達約15W。 

The different ambient conditions in industry and in building technology result in requirements on the mechanical, chemical, thermal, fire-related, and even electromagnetic resistance aspects. The system partners contributing their experience in this field are Datwyler and the Draka Prysmian Group.

Ethernet in general and SPE in particular play a central role in the establishment of the Industrial Internet of Things. Often, however, the need for further training of employees is not considered when introducing such technologies. This is where University 4 Industry helps with online learning content from various areas of IIoT, e.g. on the topic of Ethernet APL.

在工業物聯網的搭建中,以太網尤其是SPE起著核心作用。不過在引進此類技術時,人們往往忽略對員工進行進一步培訓。University 4 Industry在線學習平臺幫助開展工業物聯網相關領域的培訓,比如關于以太網APL主題。
