If you choose to develop your own motion control algorithms but still use EtherCAT to simplify and support your network configuration, KINGSTAR Fieldbus powered by EtherCAT is the way to go. Because KINGSTAR supports EtherCAT, you can use Ethernet cables to connect EtherCAT-enabled servo drives to your PC, and KINGSTAR will auto-configure the complex EtherCAT settings for you. You no longer need a physical PLC; the PLC software bundled with KINGSTAR can not only define the logic of devices on your PC, but control the input and output of devices through the EtherCAT connection.
