This PLC program tutorial by http://www.bin95.com is one of the PLC projects in DVD 10's implementation section. The project starts with converting a motor control circuit to a plc circuit in PLC relay logic. This is just a small, low resolution sample from DVD 10 of the 10 DVD PLC Training Video Course Library. The actually DVDs have much better quality and more details. http://www.youtube.com/watch?v=FpR59v04ptY
