Learn about the latest Single Pair Ethernet standards being developed along with examples of how SPE Technology is being used in industrial and building automation applications.
What is Single Pair Ethernet (SPE) and why is it so important for the Industrial Internet of Things (IIoT)? SPE is based on a two-wire cabling protocol offering secure communication over longer distances and with a smaller footprint. These features are central to the question of why SPE is needed. As more and more devices in commercial and industrial applications become “connected”, there are increased demands on space both inside the devices and in the cable ducts that connected them together. And while WiFi has its uses in these environments; it does not offer the security or reliability of a wired communications network.
Single Pair Ethernet (SPE) technology is expected to be a significant driver of Industry 4.0, bringing transmission speeds from 10Mbit/s to 1GBit/s across simplified cabling infrastructure, while saving space and weight. SPE promises to save factories time in setting up, maintaining, and operating industrial networks, while enabling power supply and better reliability of terminal devices through its Power over Data Line (PoDL) capability. Cabling Installation & Maintenance recently sat for an interview with Peter Jones, Chair, Ethernet Alliance and Distinguished Engineer, Cisco; and Bob Voss, Senior Principal Engineer, Panduit and an industrial automation industry technical expert and association member.
The Ethernet Alliance has launched a new industry focus around Operational Technology (OT) networks found in building and industrial automation. With the development of Single-Pair Ethernet (SPE) creating new opportunities for solving challenges in OT networks, the Ethernet Alliance says it is seeking to connect with more expertise in the building- and industrial-automation industries.
As Ethernet transmission speeds increased, the IEEE recognized the need for additional options to sup-port lower-speed transmission rates for specific applications and environments.As a result, the most recent addition to the IEEE Std 802.3 standard is the IEEE Std 802.3cg-2019 amendment specifying 10-Mbit/sec transmission over single balanced twisted-pair copper ca-bling. While initially targeted at industrial and automotive environments, there are also opportunities for building automation functions. This article will examine the network architecture and use cases made possible by the application of this new technology in support of published SPE standards.
Standardization of OT and IoT onto a single protocol is critical to driving widespread adoption of digital transformation. Single Pair Ethernet (SPE) is an enabling technology for many industries and applications with a special benefit to industrial control networks: providing the ability to operate a single, seamless network from cloud to edge and providing the option to power end devices over distances longer than traditional ethernet cabling. In this webinar, Mike Vermeer will discuss how SPE can impact future cabling deployments. Watch on demand.
Single Pair Ethernet (SPE) promises a consistent Ethernet connection from the sensor to the cloud. When it comes to the network infrastructure for the Industrial Internet of Things (IIoT), users hope it will allow them to implement a consistent communication architecture in all applications where data is present by extending the Ethernet connection down to sensor level, i.e. wherever there are no data highways but where users need compact data transmission with a long reach.
Siemon’s TERA cabling system supports 10BASE-T1L single-pair Ethernet (SPE), providing an easily-deployed, standards-based infrastructure that simplifies cable management, reduces costs, and enables more efficient use of pathway space. As explained in a new Tech Brief developed by Siemon’s Valerie Maguire, Distinguished Engineer and Chief Editor of the IEEE Std 802.3cg™-2019 10 Mb/s Single-Pair Ethernet project, 10BASE-T1L operation over TERA SPE cabling offers many advantages over traditional/proprietary operational technology for monitoring and controlling simple, low-speed devices in commercial enterprise environments.
In a live webinar with our Ethernet experts Harding will highlight the capabilities of Single Pair Ethernet and show which IIoT applications are made possible by SPE. We talk about how SPE helps the Smart Factory get on its feet and provide examples from the fields of automation, transportation, automotive and robotics.
Bandwidth-hungry electronics are increasing on aircraft as passengers and crews expect more from in-flight entertainment, cabin lighting, security and freight monitors, and other features. A significant amount of wiring and connectors is required to enable these capabilities, and designers need to implement smarter connectivity solutions without adding weight. This 60-minute Webinar explores how the adoption of Ethernet technology is evolving to support the SWaP and performance needs of modern aircraft cabin networks.
