Sorry, to begin with it, I'm a novelty here. Myself can characterize as a 'agelong student'. There are some misgivings in drowings of LADDER LOGIC section of your book. Or at least it is the way I understand it. Unfortunately I do not have a means to drow in this space, I could have put it pricisely. jsz.

 

Can you explain what the "misgivings" are? Without an indication of what the errors might be there is not a lot we can do with respect of correcting them.
