I'm using a dvp32es2 plc to monitor machine usage in our factory. The PLC is reading a current trasformer to determine when the machine is switched on. However, I would like to be able to log this info as well. At least on an hourly or dialy basis. I'm not sure if there is a way to automatically log data with the PLC or if I hve to sav e the values to an icreading array of registers?
