The goal of the new SPE standards is a single-network vision where all devices in plants communicate using the same set of protocols–balancing node cost, node size and ease of commissioning smart systems.
Harting Americas has launched their Single Pair Ethernet technologies.SPE communicates across the common industrial Ethernet protocols available today but instead of using 4 or 8 total wires, it accomplishes communication across just two wires, a single twisted pair. It uses Power over Data Line technology to bring communication to the device along with the voltage and amperage needed to power the device. This is hugely beneficial for three reasons:. First, space and number of connections are reduced on the device. Second, the need for an external power supply is eliminated. Finally, devices on the plant floor that have traditionally communicated over Fieldbus protocols can now join the same IP-based network that the rest of the devices on the network are using. This enables peer-to-peer communication, open-loop feedback of all devices, and smart functionality all the way from the main control room down to the individual device.
The IEEE 802.3cg standard is a single-pair Ethernet standard that that supports speeds up to 10 Mbps and extends Ethernet range up to 1,000 meters. Learn about 802.3cg’s two link-layer standards, 10Base-T1S and 10Base-T1L, and what they mean for IoT and automotive applications.
TIA’s TR-42.7 Engineering Committee on Telecommunications Copper Cabling Systems (568) has issued a call for interest for document ANSI/TIA-568.6, initially titled, “Single Pair Multi-Drop (SPMD) cabling and component specifications.” The standard will address the need to support applications that use a bus topology with multiple branches connecting communication devices.
In its outlook for 2020, R&M has identified 8 key trends spanning across public, data center and local area networks.These include: Convergence, Single Pair Ethernet vs. Field Bus, Leveraging FTTX, WDM and Blown Microfiber, Leveraging 5G, Greater Importance of the Edge, High Density Data Centers, and Automated Infrastructure Management in Data Centers.
Fluke Networks demonstrated a prototype single pair Ethernet (SPE) adapter for its DSX-8000 at the Rockwell Automation Show. SPE is making waves in the industrial-automation world as a potential replacement for fieldbus architectures. The adapter is being made in very limited quantities and is currently only available to industrial automation and cabling manufacturers for their use in labs but has been released with the expectation that SPE will become widely adopted.
Cabling Installation & Maintenance interviews Frank Straka, Panduit’s product line manager for copper products, about the Single Pair Ethernet Consortium, discussing the group’s objectives, the single-pair ecosystem, Panduit’s role in the group, and some forthcoming products related to this emerging technology.
A new Ethernet protocol has been designed to operate over a single pair of UTP/STP cable – otherwise known as single-pair Ethernet. Although, individually, these devices don’t call for much power or bandwidth, the sheer number joining our networks (75 billion or more by 2025) will increase overall bandwidth needs.To discuss advances in technology, the Single-Pair Ethernet Consortium (SPEC) was formed, bringing together organizations that make single-pair Ethernet devices, equipment and connectivity. The group’s hope is to nurture the adoption and growth of single-pair networks in a standards-compliant ecosystem that discourages proprietary network types and instead makes use of Ethernet.
From the BICSI Fall Conference in Las Vegas, NV, our chief editor Patrick McLaughlin previews some of the technical content that will be delivered to attendees. He also interviews a founding member of the TIA’s newly created Single Pair Ethernet Consortium
The Telecommunications Industry Association (TIA) established the Single Pair Ethernet Consortium (SPEC) to accelerate the adoption of next-generation operational technology (OT) and Internet of Things (IoT) connectivity. Founding members of SPEC include Belden, CommScope, Panduit and the Siemon Company. SPEC will provide vendor-neutral representation for technology leaders and users across the building automation technology ecosystem.
