Storage media which has been tested and approved by Siemens ensure the best possible functionality and compatibility.
SIMATIC storage media are suitable for industry and optimized for the requirements in industrial environments. Special formatting and write algorithms ensure fast read/write cycles and a long service life of the memory cells.
MultiMediaCards can also be used in operator panels with SD slots. Detailed information on usability can be found in the storage media and panels technical specifications.
The actual memory capacity of the memory cards or USB flash drives may change depending on production factors. This means that the specified memory capacity may not always be 100% available to the user. When selecting or searching for core products using the SIMATIC selection guide, accessories appropriate to the core product are always automatically displayed or offered.
Due to the nature of the technology used, the reading/writing speed can diminish over time. This is always dependent on the environment, the size of the files saved, the extent to which the card is filled and a number of additional factors. SIMATIC memory cards, however, are always designed so that typically all of the data is reliably written to a card even when the device is being switched off.
