Phoenix Contact, Weidm ller, 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易损部件2：板卡 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.
随着单对以太（SPE）技术的发展，菲尼克斯电气、魏德米勒、R M、福禄克络, 以及德力格能之间的技术合作不断加强，并成立了SPE系统联盟。该联盟将来自不同行业和应用领域的领先技术公司聚集在一起，整合各自的SPE专业知识并针对性地开展交流。该联盟的成员以追求推动SPE在工业物联（IIoT）以及相关领域的进一步发展为目标。目前，包括德特威勒、东土科技、微芯科技、罗森伯格、西克、威力工业络、Draka/Prysmian集团和University 4 Industry等公司也正式加入该联盟。
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 p卸力后拧紧油处接头,材料rovide 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.

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 Teleg rtner provide Digital Ceiling solutions and can show the implementation of SPE into such a system.
SPE provides consistent I新国标基于风险评估的基础上制定相干规范性要求和限制指标P 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 Teleg rtner develop compact device and cable connectors in accordance with the standardized and fully compatible interfaces in accordance with IEC (IP20) and (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.
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应用领域中，传输信道是由各种电缆和连接器组成。虽然在系统标准（例如ISO/IEC 11801系列标准）中通过传输参数（例如带宽、衰减、回波损耗和防护尺寸）指定了传输通道，但是必须根据各自的通道量身定制连接器和电缆 。
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 series of standards and those following).
IEC46C委员会正在积极推进这项工作，固定路由带宽为20 MHz的线缆，适用于10BaseT1的信号传输，带宽为600 MHz的电缆适用于100BaseT1和1000BeT1的传输（IEC 系列标准及关联标准）。
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的优势实现了信号和电源同步传输，例如从开关到传感器。在建筑布线领域被称为PoE，在这里称作单对电缆（PoDL，power over data line）。基于横截面和线缆长度，传输的电能可达约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.
在工业物联的搭建中，以太尤其是SPE起着核心作用。不过在引进此类技术时，人们往往忽略对员工进行进一步培训。University 4 Industry学习平台帮助开展工业物联相关领域的培训，比如关于以太APL主题。四平工服订做
