    Siemens S7 PLC SD memory card

    Hi guys, i've been trying to copy the program on an S7 EPROM mmc and backing it up to another, I'm using a siemens field pc to read the program, i can Copy but not paste, I can't find any way to duplicate what's on it, for some reason the plc will not let me communicate through the mpi.
