Being a retired controls electrician for me it would be much easier to find a problem if diagrams were in ladder format instead of wiring diagrams. It would be simple left to right instead of going around in circles.
and also could tell what is normally open contacts and normally closed contacts. Also mark those modules to show what is input voltage and what is output voltage.I agree with you so much on that. It would be so much easier and you could actually see what wire actually connects to what... not just a bulk of wires goes from A to B.
