HMI accessories, storage media

Storage media

Storage devices, memory cards and USB flash drives tested and approved by Siemens ensure the best possible functionality and compatibility.

SIMATIC HMI 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.
Further information can be taken from the operating instructions of the respective devices.

The following storage media are available:

• Multi Media Card
• Secure Digital Memory Card
• SD memory card Outdoor
• PC memory card (PC Card)
• PC memory card adapter (PC Card Adapter)
• CompactFlash Card
• CFast memory card
• SIMATIC HMI USB memory stick
• SIMATIC HMI USB FlashDrive
• Pushbutton Panel memory module
• IPC memory expansions

Note:

Do not use SIMATIC S7 Memory Cards from S7 controllers in operator panels or PC systems. When used in this way, these memory cards lose their functionality and can then no longer be used with S7 controllers.

Cyclic archiving may place very high stress on the memory and could lead to failure. In this case, it is necessary to calculate the write cycles in respect of the frequency and size of the data volume in advance. Network drives are more suitable for archiving larger data volumes at short to very short intervals.
This rules out any repair or replacement.
