Description
10BASE-T1L is an Ethernet physical layer standard (IEEE 802.3cg-2019) that is dramatically changing the process and factory automation industry by providing seamless Ethernet connectivity to f ield-level devices including machines, controls, indicators, sensors, and actuators. 10BASE-T1L improves on existing standards such as 4 mA to 20 mA, HART, and FieldBus. Similar to conventional process automation networks, 10BASE-T1L allows both data and DC power to be transmitted over a single twisted pair via single-pair power over Ethernet (SPoE) or Ethernet advanced physical layer (APL).Compared to traditional methods, 10BASE-T1L offers higher power delivery, higher bandwidth, longer transmission distances, lowercost cabling in new installations, and reuse of 4 mA to 20 mA and RS485 wiring when retrofitting legacy installations. Ethernet supports PROFINET®, EtherCAT/IP, HART/IP, OPC UA™, Modbus®/TCP, and IoT protocols such as message queuing telemetry transport (MQTT). Ethernet also enables simple, centrally controlled software updates right down to the end nodes, which enables faster network commissioning and maintenance.The circuit shown in Figure 1 is a 10BASE-T1L MAC/PHY interface with SPoE for development of field devices and applications on a Raspberry Pi platform board. The SPoE powered device (PD) and isolated flyback regulator provide 5 V power to the platform board and attached application circuitry. SPoE Class 12 (8.4 W, 24 V nominal) and Class 13 (7.7 W, 55 V nominal) are supported.The MAC/PHY interfaces to the platform board via serial peripheral interface (SPI), allowing it to be used with microcontrollers and processors that lack an integrated media access control (MAC) layer. The circuit includes a digital temperature sensor, LEDs, and push button, which implement a basic field device example application. The example field device’s drivers are in the Linux industrial input/output (IIO) subsystem, providing a host of debug and development utilities, and cross-platform application programming interface (API) with Python, C, C#, and MATLAB® support.
