The primary motivation behind 10BASE-T1S was to bring Ethernet capabilities to edge devices in automotive and industrial settings while addressing the specific needs of these environments such as space constraints, electromagnetic interference, and the need for simplified, cost-effective networking solutions.
Summary of the background and motivation for Ethernet 10BASE-T1S:
- Designed for automotive and industrial applications:10BASE-T1S was developed to meet the needs of automotive and industrial environments where space, weight, and electromagnetic interference are critical factors
- Replacement for legacy protocols: It's designed as a next-generation network to replace protocols like CAN and CAN-FD in automotive applications
- Simplified wiring: 10BASE-T1S uses a single twisted pair of wires, reducing wiring complexity, weight, and cost compared to traditional Ethernet technologies
- Seamless communication: It enables seamless communication from field devices to factory backplanes in industrial settings, eliminating the need for protocol conversion
- Multi-drop capability: Unlike many Ethernet variants, 10BASE-T1S supports a multi-drop bus architecture, allowing up to 8 nodes (minimum) on a single bus segment of up to 25 meters
- Cost reduction: The multi-drop capability and simplified wiring reduce the total system cost by requiring fewer switch ports, cables, and switches
- Standardization: It was standardized by IEEE 802.3cg-2019 to provide a 10 Mbps communication option for short-reach applications
- Compatibility with Ethernet: 10BASE-T1S maintains compatibility with standard Ethernet protocols at higher layers, allowing easy integration with existing Ethernet infrastructure
- Physical Layer Collision Avoidance (PLCA): It introduces PLCA to manage communication on the shared bus, improving efficiency in multi-drop setups
- Versatility:10BASE-T1S is suitable for various applications, including in-cabinet wiring, backplanes, field sensors, and intra-system communication on PCBs.
