Hi,

I am newbie on Step7 and I had help in this forum for my project.
So, please, help me.

IO not responding but hardwarea configuration should be ok.

Where I am wrong?

Thanks in advance.

OK, resolved.

24Vdc missing.

You have error lights on all your power modules. My first guess is that they are missing 24V.

Step 2, I guess, is to make sure that the part numbers for the PMs (including FW versions) match.


Edit: and you posted at the exact same time I did, hi5 for figuring it out!

 

[L D[AR2P#0.0]]

You can configure the PM/E to give diagnostics if the 24v supply is missing. Unfortunately, the default setting is no diagnostics.

Have a nice day.
