Omron CPM1A Program recovery from death internal power supply 

In this video I show you how to hook up CPM1A controller portion of the plc to a external power supply and give the correct signal so the plc actually run and communicate. Our company work in automation and find ways to save time and money to customer using creative mean like hardware hacking when needed. In this case no backup and no shematic were available on this machine, so, reverse engineering of the system was hard and the machine is working outside at freezing temperature. Hope this video help you recover some of your machine.
