Only a PG or a portable MMC reader can read these cards directly. It appears that someone has inserted the 'bad' MMC into a PC and allowed the PC to format it (put a FAT table on it). The card is no longer usable in SIMATIC. I do not know for sure if Siemens offers a reformatting service or not, but it would not hurt to ask. Wish I had better news.

Warning: Do not use the MMC for non-SIMATIC purposes and do not format it with a third-party device. This would possibly overwrite the internal structure of the MMC that cannot be restored. In this case the MMC is no longer recognized/accepted in a SIMATIC CPU and can no longer be used with SIMATIC devices Please have a look on this thread. So My recommendation is to order a new MMC specially it's not so expensive. Hope this helps, Regards,

Now i have only one (formated) memory card . could anybody send simatic images and files of the simatic MMC. is it possible to send that file to MMC through mmcport(not using card reader). If i should use card reader means should i use normal card reader or simatic card reader.

If you get the image from any where, I am sure that Siemens does not grantee that MMC. Please check the following FAQ: Why is the MMC no longer recognized by SIMATIC devices after it has been formatted in a third-party device? Regards,
