Five Ways Single-Pair Ethernet Optimizes Modern Industrial Networks
McKenzie Reed, SPE Lead, HARTING Americas
Industrial Single-Pair Ethernet enables the transmission of Ethernet data over just one twisted pair of wires, rather than two or four, and is ideal for use in industrial-grade applications including factory automation, robotics, and railways.
The automotive industry has successfully used Single-Pair Ethernet (SPE) to replace CAN bus and other in-vehicle communication networks for years. Now, the benefits of SPE have been extended to the industrial automation market thanks to the combined efforts of a number of suppliers that worked closely with international standards organizations to define and standardize new SPE connectivity solutions that fulfill the unique demands of industrial market segments.
SPE will change the way that industrial applications communicate with one another. While other communication protocols may address some of these demands, the combination of benefits provided by SPE is what makes it so important for the future of industrial communications.
» HARTING’s T1 Industrial connector serves as the standard mating face for Industrial SPE and is ideal for the construction of future-proof SPE communication networks with standardized cabling according to ISO/IEC 11801 and TIA 42. The T1 Industrial connector supports common Industrial Ethernet protocols including Ethernet/IP, PROFINET, and EtherCAT with a single twisted pair of wires, instead of four or eight, and employs power-over-data-line (PoDL) technology to provide the communication, voltage, and amperage capabilities needed to power an array of Industrial Ethernet devices.
1. High Bandwidth, Speed, and Security for Critical Applications
Industrial machines produce more data than ever before. Cameras used in machine vision applications, for example, need to be able to produce, send, and receive HD video data in real-time to support critical devices within industrial networks. While fieldbus protocols can provide reliable and deterministic communication, they lack the speed
