Hi ger600, welcome to the Technical Forum! Are you asking because you want to erase the PLCs data? If yes, follow the instructions at 'Resetting to factory settings'. If you are asking because you are afraid that a memory card erased your PLC, then the answer is "This should not happen". You will find more about memory cards in the manual. Kind regards |

Hi ger600, changing the memory card between two PLCs would only work with the same or at least compatible PLC types. Due to technical changes (more memory) it is possible that a PLC that used to require a memory card now runs without a memory card. A typical mistake is not to change the settings for startup after power off. Since the S7-1200 PLC do not have a hardware switch, an alternative way like described in FAQ 'How do you change the operating mode with a S7-1200 CPU?' is needed. Kind regards |
