I'm working on a PLC S7-300 and unfortunately this morning I formatted wrongly my MMC memory card and now It is not possible to use it anymore! Do you have any solution about that?

Thanks in advance.

Dear ,

could you explain in detail how you formatted the MMC Card by  USB card reader or Field PG Simatic card reader . IF you formatted with the external USB card reader it is not reusable sorry new you have to use new MMC card only. but if you have formatted with field PG Simatic Card reader you can use it.

Thanks & regards

hi giangybar,

here are official FAQ for this:

How do you format or reset an MMC (Micro Memory Card) for SIMATIC S7-300 CPUs?

Why is the MMC no longer recognized by SIMATIC devices after it has been formatted in a third-party device?

In STEP 7 (TIA Portal), how do you format an MMC or MC and why does a message appear saying that the SDB 7 is not loaded?

hope this helps,

If MMC is formated without Siemens Field PG

 Hello vinit,

there is not only the Field PG for this work

Which devices can you use to read from, write to or delete from an S7-300 MMC (Micro Memory Card) outside the CPU?
