[NB-Designer] HMI "PLC No Response" error [SOLVED]

[olivier123 0]

Hello everybody,

I continued my project this morning and my HMI gives the 'PLC No response 00-02-3" error... I haven't changed anything since last Friday, so in theory it should work. I used this tutorial a few weeks ago and that worked. I also tried so use some old programs which used to work, but they don't work now... 

HMI IP: 192.168.250.1 (the addresses from the tutorial)
PLC IP: 192.168.250.2 (the addresses from the tutorial)

 

Does anyone know what could be the problem? I already tried using another switch, but that didn't work either.

EDIT: I just saw that I posted this in the wrong subforum, excuse me

EDIT2: I found the solution. I cleared the data memory before... So what I did was transfering the settings to the PLC, then completely power off the PLC and then power it on again. That worked for me!

Thanks,

Olivier

This is very common. Thanks for posting your solution.
