I just wanted to take the time to thank everyone on this site who takes the time out of their busy schedules to help others learn. I just recently got a job as a maintenance electrician and finally have the oppurtunity to learn about plcs. 15 years as a construction electrician. I have a bit of programming background-took basic in high school and pascal in university. I am totally addicted to plcs. I love learning about them and then going and experimenting with my newly acquired knowledge. This site is the single best resource that I have found. I have a PLC5 in my computer room at home and I am putting it through the ringer. I have learned so much just browsing through this forum. I have noticed that a lot of the "BIG DOGS" give so much of their time and expertise without even as much as a thanks sometimes. I just want to let you all know that I for one truly appreciate your efforts. You all know who you are. Kudos gentlemen.
