The Industrial Raspberry Pi Forum

Good morning
this is not the first time that I connect to a revpi from Codesys, I have always installed it and it seems to work, except this time I manage to see the device and I send codesys control for raspberry pi SL 4.6.0.0 on it without problem, however when I try to connect to the device it asks me device user logon I type my user revpi and my password but it doesn't work, it's the same ones that I used to connect to it and to send the codesys control to it, is there a way to get around this or to reset the mdp, namely that I have already changed the mdp user for the revpi and it does not work always not.

Take a look at this tutorial, which implements a "Blinking Light": https://revolutionpi.com/en/tutorials/b ... ng-light-2

To keep your system up-to-date and compliant, I recommend this checklist:
