Thanks in advance to those that read this and especially those that can help!
I have a Siemens S7-200 (CPU 224) and am stumbling to learn how to use it.
Communications are ok, and even though I'm operating the outputs I'm only getting 3V out (DC/DC/DC version).
Everything looks ok and there seems to be no fault indications.
I also have an input with 24V on it but no LED - is this normal or is my CPU at fault?
It's a used unit so I'm not tooo sure about it and I can't find too much in the manuals.
Once again thanks and apologies if the answer is blindingly obvious!
