18 ADI | Industry 4.0 and Beyond the challenges that, to date, have limited the use of Ethernet to the field assets. These challenges include power, bandwidth, cabling, distance, data islands, and Intrinsically Safe Zone 0 (hazardous areas) applications. By solving these challenges for both brownfield upgrades and new greenfield installations, 10BASE-T1L will enable new asset health insights previously unavailable and seamlessly communicate them to the control layer and to the cloud/private server. These new insights will awaken new possibilities for data analysis, operational insights, and productivity improvements through a converged Ethernet network from the field assets to the cloud or private server (Figure 2). Advantages of 10BASE-T1L Ethernet Connectivity 10BASE-T1L removes the need for complex, power- hungry gateways required by legacy communications to connect to the control and management network and enables a converged Ethernet network across the information technology (IT) and operating technology (OT) networks. This converged network delivers a simplified installation, easy device replacement, and faster network commissioning and configuration. This results in faster software updates with simplified root cause analysis and maintenance of field-level assets. The 10BASE-T1L physical layer combined with messaging transport protocol (MQTT) provides a messaging protocol for field assets with a low memory footprint for lower-power smart sensors. MQTT provides direct connectivity of asset health insights to the cloud or a private server for advanced data analytics for predictive maintenance techniques. To communicate with a 10BASE-T1L enabled field asset, a host processor with integrated medium access control (MAC), a passive media converter, or a switch with 10BASE-T1L ports is required. Additional software, special drivers, or customized TCP/IP stacks are not required (Figure 3). This results in clear advantages for 10BASE-T1L devices: 10BASE-T1L is a very low-power physical-layer technology that can enable very low-power smart sensor deployments with a high-data bandwidth connectivity solution. A smart sensor connected with 10BASE-T1L is accessible over the network and can be remotely updated anywhere, at any Figure 2: Asset health insights on a converged IT/OT network.
