field pg p4 MMC read error

Ronnie_B

Hi, I have a problem with our new PG M3.

If I insert a MMC into the cardreader and tries to access it in Step 7 I get an error message "EPROM MMC missing".

If I insert a camera SD into the slot I can access all the photos in Windows Explorer without problem.
So to me the card reader is working fine but not the connection to Step 7.

Also the "Memory Card Parameter Assignment" is set to "Internal".

What else to check?

It used to work fine earlier and I only updated Scout and WinCC Flexible but should that effect?

Hello,

Are you sure that card is OK? Do have another one (Siemens) in order to try it there?

Best regards,

Problem is solved.
I just remembered there is another slot for the Simatic MMC additional to the standard cards.
I guess I will excuse my self with "It's Monday".
