Hello diosnel, from what you say you have an old CPU "flash eprom" with the big blue card right? Do you want to delete the rom? or do you want to erase the EEprom? How can you obtain an overview of the memory concept of SIMATIC S7-300 CPUs and C7 devices? |

Hi, Please havea look: Which devices can you use to read from, write to or delete from an S7-300 MMC (Micro Memory Card) outside the CPU? If you want with accessible node, open the SIMATIC Manager and go to PLC/Display Accessible Nodes open the view of the blocks Accessible Nodes / MPI = .../Blocks" (click on "+") and here you should see if your blocks are stored in EEPROM or RAM |

Hello, So that's an oldy with battery, right? That one behaves a little different than the new ones without battery an MMC. Maybe this helps: SIMATIC S7-300 CPUs and SIMATIC C7 devices with built-in RAM and an external memory card (MC) |
Problem solved? |
