Choosing how to drive the bus

Section titled “Choosing how to drive the bus”

AUTD3 is driven over EtherCAT. There are three options, depending on where the EtherCAT master runs.

  • Appliance (recommended)
    • A dedicated board runs the master and the host connects over TCP. For any host OS, and when you want the bus decoupled from the host’s load and OS settings.
  • echocat
    • The host itself becomes the master. When you do not want to add hardware. Needs npcap on Windows and raw socket privileges on Linux/macOS. It may also become unstable under host load.
  • TwinCAT
    • Windows only. Needs a supported network controller and a TwinCAT setup. The most stable of the three.

Unless there is a reason not to, the Appliance is recommended, though it additionally requires a Raspberry Pi 4, a microSD card and a USB Ethernet adapter.
