Thanks for the info guys. It is presently at the Radwell Int (PLC Center) in NJ. They will test it and call me. $67.00. That includes getting it back to me. Bigleo, they sell this same PLC for about 200 bucks. It is an S7-200, CPU 212. Any idea what my distirutor sold it to me for?????? Try $700 bucks. Again, thanks. Bud
