  1. 1

    Verify the physical EtherNet/IP cable connections between the Omron EtherNet/IP driver and the external device, ensuring secure connections and checking link/activity LEDs on both devices.

  2. 2

    Check the IP address and subnet mask configurations for both the Omron EtherNet/IP driver and the external device to confirm they reside within the same network segment.
