Hello

I would like to know how to format MMC which is inserted In S7-300 PLC by means of deleting all data and make it just like brand new bought MMC. I have looked for it and all I found was I need to have Siemens prommer or PG to read and delete. I have also found mRes but I don't think this is the function that I was looking for.

Thank you
