Procedure to Restore an Image to a New MMC

  1. Insert blank or previously used MMC (Siemens original only; third-party MMCs fail).
  2. In S7ImgRW → Click “Write MMC” → Select your image file.
  3. Confirm overwrite → Wait for completion.
  4. Insert the new MMC into the CPU → Power cycle → CPU should boot with the original program.

1. What Is an MMC Image File?

An MMC image (usually .img, .bin, or .s7img) contains the complete contents of a Siemens MMC, including:

Important: You cannot download generic “MMC image files” from Siemens’ public website for free — because the image includes proprietary CPU firmware and user program data. Siemens only provides firmware updates (not full card images) via their Industry Online Support.
