CNC routers use step and direction signals to control each stepper motors. In addition motor information (position, temperature, fault) gets transferred from stepper motors back to control unit. This must be done in star topology and a mix of proprietary interfaces. Simple open real-time Ethernet (SORTE) enables 4 µs cycle time on industrial Ethernet and replaces step/direction signal and motor feedback info into a single Ethernet cable that is also wired in line topology.

What you will learn:

  • Industrial Ethernet in Factory Automation
  • Industrial Ethernet Standards
  • Simple Open Real-Time Ethernet (SORTE) Protocol
  • CNC Router with Industrial Ethernet
  • Programmable Real-time Unit and Industrial Ethernet Subsystem (PRU-ICSS) and the Industrial Ethernet Interface (MII_RT)
  • TI Designs, Analog and Embedded Products for Industrial Ethernet
  • Summary: Benefit of using SORTE and PRU-ICSS
