If you can see 2 lines repeated with different icmp_seq and time, then probably there is another application using the standard RSI port number 49152, try using different port number.

64 bytes from icmp_seq=1 ttl=255 time=0.220 ms
64 bytes from icmp_seq=2 ttl=64 time=0.248 ms (DUP!)

If the ping result is different, then please :

  • Ensure that the Ethernet cable is connected to the controller Ethernet connection labeled X66.
  • Recheck your network connections between the IPC and the controller.
  • Connect the IPC to the controller directly without any network switch/router.
  • Recheck your KRC4 RSI network Configuration.
