I am a senior in college and have been working with RSLogix5000 and RSView Studio with a PanelView Plus 1000 for a while now. I am very interested in PLC and need a suggestion on any books I can read to further my learning before graduation. I have taken all the courses offered at my college and done a little independent work with them so I understand most of the basics. I would like to get into understanding the motions especially. Any suggestions would be greatly appreciated. Thanks
