Note from Ron: For the past several years, I've been writing extensively on several public web forums dedicated to PLCs. Much of the material listed below has been previously posted as answers to specific questions from other forum members. In response to many requests, I've included just a few of my favorite forum posts here in a handy PDF format. Please consider these as samples of the amount of detail which I provide in all of my classes - and demonstrations of the common-sense approach I use when teaching. I hope that you'll find these useful. I'll be adding more material here in the future as my schedule permits.
