How 10BASE-T1L Building Controllers Are Enabling Sustainable Building Management Systems

This article highlights the benefits of using Ethernet direct digital controllers (DDCs), also known as building controllers, in building management systems (BMSs) and explains how the 10BASE-T1L protocol can fit into a typical BMS architecture. With its 10 Mbps data rate, support for various topologies, and power over a single-twisted pair cable, 10BASE-T1L provides seamless Ethernet connectivity to DDC controllers and edge nodes in point-to-point, ring, and line network configurations. It offers real-time control and overcomes the limitations of previous protocols while supporting virtually unlimited numbers of edge nodes. Its ability to transmit data over long distances up to 1 km makes it an ideal retrofit solution for existing BMSs as it can reuse existing single-twisted pair cabling. Its features eliminate the need for power-hungry gateways, enabling seamless edge-to-cloud connectivity. This makes it a valuable resource for those interested in the latest BMS technology and its potential impact on energy efficiency in buildings.
