As nobody responded yet... It sounds like a firmware issue. Maybe try to contact Siemens Support and confirm it with them. Firmware version of the hardware can be modified, see the Operating System Update for S7-400 Standard CPUs (FW V5.1.1) article for further info. |

Hi, Just a small information you may find usefull: You do not need flash card to update firmware. See SIMATIC Configuring Hardware and Communication Connections STEP 7 V5.5 under chapter "13.1.5 Updating Firmware in Modules and Submodules Online" I hope I could help! |

Hi, Unfortunately I can't do this because my CPU doesn´t support the "Update firmware" function. I already asked SIEMENS about it and they told me that I realy need the memory card. Thanks for your information Romero Spinasse

Hello, Is this memory reset happening in both the CPUs or only one? I had the similar problem. Turns out that problem with the sync module can erase your CPU. Please refer to my post. In your case also may be some of the faulty component is causing this memory reset? hope this helps. Kbv. |
