Cant help without info.

  1. can the computer running node-red runtime PING the PLC?
  2. what settings have you entered in the PLC Ethernet setup?
  3. did you power off/ power on the PLC after adjusting PLC settings?
  4. what settings have you entered in the MC-Protocol nodes config?

Thanks for the response Steve .

  • can the computer running node-red runtime PING the PLC?
    Yes . It pings back successfully with the PLC
  • did you power off/ power on the PLC after adjusting PLC settings?
    No. I have not tried that.
  • what settings have you entered in the MC-Protocol nodes config?
    I had selected the PLC Series as "Q" (which I had already used in my Kepserver side).
    Then I have entered my PLC's respective IP with the port address.
    I had tried with TCP first, I was not getting "not connected" result. And then I went with UDP, there I got the "timeout error" (it tries reading the tag and after that timeout error is shown)

  1. Have you added UDP port in the PLC Ethernet settings?
  2. Can you show me exactly what you have entered in PLC Ethernet settings?
  3. Can you show me exactly what you have entered in NODE Config?

cant really help otherwise.

PS: Remember to power cycle the PLC after changing settings (come on mitsi, its 2022 not 1985!)
