Many of today’s automation networks were built using different communication protocols, from serial to bus to ethernet. Ideally, networks would be built up using Ethernet, eliminating inefficient protocol conversions and/or transparency limitations in the information flow. The factory floor is the last part of the industrial network that has not been using Ethernet (yet). Single Pair Ethernet (SPE) will help drive this. SPE gives engineers a solution that goes together with the traditional 2x2 and 4x2 Industrial Ethernet, building an all-Ethernet network that allows full transparent communication. TE Connectivity believe SPE is essential to build the infrastructure supporting the Industrial Internet of Things (IIoT). Here are the top three benefits of SPE in machine-to-machine communication:1. SPE helps accelerate the trend in smart manufacturing because it brings secure, real-time, high-speed communication connections up to 1Gb/second on to the factory floor and cable length up to 1,000 meters for 10Mb/second supporting the process industry.2. SPE helps build more efficient network systems because of Ethernet communication from the sensor to the cloud. It helps reduce network complexity and costs.3. SPE helps brings Ethernet usage to the factory floor. Where RJ45 was not an option for the network edge, SPE uses smaller connectors. SPE makes equipment miniaturization possible and combines data with remote powering to link an edge device with a single cable: Data with power over data line (PoDL) or with a separate supply wire pair (for high power) in a hybrid connector solution.SPE combined with the traditional Industrial Ethernet allows for the build of all Ethernet networks (from the sensor to the cloud). This is the basis to build the infrastructure supporting the Industrial Internet of Things (IIoT).
