Dear Ahmed, Although you can read the SIMATIC MMC from PC card reader, but SD cards can not be read from CPUs. due to change in the interface. You can trat the SD card as a formatted MMC and use thirdpart software to put an image of SIMATIC MMC on SD card and try it your self. But again, I do not recommend using this software. (just my two cents.) Here's attached pictures of both MMC & SD card (rear side). Hope this helps.

Hello MMC ( Micro Memory Card ) ( https://en.wikipedia.org/wiki/MultiMediaCard) is different from SD card ( Secure Digital Card ) ( https://en.wikipedia.org/wiki/SD_card) and should not be confused with the same ( Although they look quite similar it first glance ). I think Hardware wise there is no difference between a SIMATIC MMC card and commercial MMC cards available in the market. They are formatted differently. That is probably why once a SIMATIC MMC is formatted in a normal MMC Reader writer it can no longer be usedas a SIMATIC MMC but can be used for normal data storage in a PC and other devices ( Athough most SIMATIC MMCs capacity is much lower than commercially awailable MMCs ) I once had formatted a SIMATIC MMC in my laptop by mistake. Could not use it in S7 again however i could easily read/write normal PC files to the MMC card like any commercial MMC card. Another difference is that all SIMATIC MMCs have a unique serial no while normal MMCs do not have any serial no. Hope this helps Cheers Navnag |
