Urgent: Simatic S7-313C and MMC

[Marjan 0]

Hello everyone, I have a problem with my memory card. I have a S7-313C with memory card. Now I can not download a program, because the the memory card is password protected and do not have a password. Is there any way to format the MMC so that I can download the program? Best regards

Not 100% sure, but I think you should be able to erase it using "SIMATIC USB-Prommer".

Also, the Simens PG has a card slot built in that can read/write the MMC directly. It's a special, proprietary SD card so standard card readers won't work. If you don't have access to a PG, try contacting your distributor. They may be able to help.

Hi, try to find on internet pages the program named S7img reader. For sure this will help you to solve that situation, using even the laptop card reader. All the best, dekor.
