MWD error, MWD timeout no connection
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?

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
