      Dear all,
      if have encountered this problem the second time now. The first time it dissapeared again but now I can´t get rid of it.

      My PLC signals a MWD communication time out by LED blinking 2s on/off.
      I am not able to run any programms anymore, in debugging mode every DI/DO/RO... is red, not working and loses its ID.
      I tried to set the MWD_enable flag again but all MWD varaivles are alos red and do not allow to change theier values (see attached pictures).
      I also tried new image flashing, countless reboots, upload new RT and configuration upload.
      Can you please help me to get rid of this error ?
      Thank you, best Regards

        @csacher I expect that all variables of Neuron are red, not only the MWD related right? What did you tried to accomplish?

        If MWD_timeout is 0 and MWD_enable is True and the HW configuration is saved (by setting NV_save to 1 of a given group) then the HW will get stuck in a bootloop because. This has been fixed in since one of the recent FW so that such value is not alowed...

          yes all variables were red
          I did not try to accomplish anything special, just deployed my solution which worked before and then I got this error.
          I did not change any of the MWD_ variables....at least not to my knowledge

            is it possible the B48_Smart_Average is the causing this ?
            it generally seems to not work properly

              @csacher Can you share your project? Do the LEDs RUN 1-3 blink somehow?

                Hi,

                I have the same behavior with my Neuron S103 using Codesys programming tool.

                RUN LED is 2 s on/off

                I can download a program to the plc and switch it to Run mode but I/O are not refreshed.
                I can see a Red triangle just before the Unipi Relays.

                Let me know how i can share my project.

                Let me know if you need additional information.

                  @nash_78 Does not seems to be related to the previous topic. It seems you are using UniPi 1 guide instead of UniPi Neuron - https://store.codesys.com/unipi-neuron-for-codesys-sl.html
