Sensors Expo & Conference 2020

The myriad of sensor interfaces are often ultimately transported to an Ethernet network. Specialized protocols on sensor networks are converted to Ethernet and IP in gateways, adding complexity and cost for users. While wireless IoT adds benefits for sensors which may not be fixed to a physical location, or may have their own power source, many sensors are fixed in location and require reliable power – resulting in at least a single pair of wires to them. Recently, IEEE 802.3 has been turning back to look at the speeds needed for sensors and actuators in OT space - industrial and building automation, intra-system applications, and automotive networks. The result is IEEE 802.3cg, published in early 2020, which adds 10BASE-T1L and 10BASET1-S for single-pair operation at 10 Mb/s and associated power delivery to the Ethernet family, enabling all Ethernet networks without gateways, and able to draw on the common Ethernet software stacks. This panel discusses the convergence of process control, industrial automation, building automation, and automotive sensor networking needs which have come together to drive these new developments in low speed ethernet, interfaces being released, and the next steps for the Ethernet ecosystem.
