After using AO for some while, the output voltage becomes max 1 volts instead of 10, is this hardware or software malfunction ?

the integer value that being written to the AO, is 4200 , but still it gives only 1 volt.

any solution for this, so far I changed to another AO channels, I will end up all of the AO channels not working.

How can I sync unipi Neuron PLCs time ( clock and date ) automatically without using Mervis software and laptop. since this process is required after system deploying and commissioning is done.

can I configure the Unipi Neuron PLC to take the time from time server ?

If I have a running unipi, already configured and running using mervis, and I lost the solution folders, can I take upload from the running PLC to my laptop, or can restore mervis sloution from the running unipi ?

Your reply does not help me to close my project.

for your information, they decided to replace by new ones, but I am sure, same issues will come again and again.

I do not know how do you keep selling non-tested products.

and to be honest with you, your products has great options, but indeed they are not reliable at all. especially hardware wise.

another issues I am facing, but I do not expect that you have a solution for those : such as :
Your product when working as modbus server - serial , it stops transmitting and keep receiving after some hours of goodTx and Rx.

your relays outputs stays on even power is off, from time to time.

for my comments on youtube, people should know what they are going to face, if they decided to go with Unipi.

simply , endless project.........................

i am working on project has four L403 unipi, and other models like M503, M403.

none of the L403 working fine.

all of them has problem in one of the groups , one two or three.

the problem is that i can not access the group relays

group run led , goes on then off, or red

and related points in mervis are red.

other models m503 and m403, are fine in this matter.

what should i do ?

i doute that replacing those will solve the issue, since i believe this model has a mal
design issues ?

any body faced my problem and solved it ?
