Card reader for S7-300 MMC

Hello SIOS Forum Community

The SIMATIC Micro Memory Card (MMC) is used in the SIMATIC S7-300 CPUs.

These MMC cards can also be read in card readers outside the CPU.

We would like to refer you to some FAQ's that provide important information on this.

Which devices may be used to read, erase from or write to a SIMATIC MMC outside of a CPU?

The prommer 6ES7792-0AA00-0XA0 mentioned in the article is set to the status P.M400, i.e. announcement product discontinuation of the external prommer "SIMATIC USB Prommer".

Information on which MMC cards may be used in the S7-300/ET 200 CPUs can be found here.
