Hello Experts [schnippschnapp] And why it is necessary for S7300 cpu to have a memory card. Initially S7 300 Cpu can run without MMC card, but now it is not working why? Splitted from Programm stored in CPU?. |

The old S7-300 CPUs uses internal memory and require a "battery" or a Memory Card (MC) The actual CPUs uses the MMC (Micro Memory Card) and no "battery". For details look here. |

In fact S7-300 use MMC as their load memory. So they'll not run any program whithout MMC. |
