The TIDEP-0085 reference design implements a Simple Open Real-Time Ethernet (SORTE) master with the Programmable Real-time Unit and Industrial Communication Subsystem (PRU-ICSS). SORTE enables customer applications to exchange process data between the master and devices in a 4 µs cycle time. The design contains open source PRU firmware to enable customer to differentiate their products.The SORTE protocol includes device discovery: parametrization: PHY and cable delay measurement: synchronization and process data exchange.
