Although I agree an electrician with computer skills can begin to understand how to program a PLC you will be a long way from mastering them. I have been working for 10+ years with them and there is still lots more to learn. Sure in a few hours you can understand the basics, but try getting involved in speed regulation and following, PID loops, communication networks, and the like and you will be humbled quickly. A PLC today is much more than a relay replacer. With that said I still encourage electricians to learn them if you took a class a few years ago the principles are the same but much of what you learned is obsolete. Keep up to date, most companies that sell PLCs are more than willing to get you started.
