Siemens SIMATIC S7 pamäťová karta 256 MB SD Flash pre S7-1200/S7-1500 PLC CPU

Industrial automation projects often stall when the PLC runs out of program memory or needs a reliable medium for firmware updates and data logging. The Siemens SIMATIC S7 memory card solves this by providing 256 MB of industrial-grade flash storage in a standard SD form factor, purpose-built for SIMATIC S7-1200 and S7-1500 CPUs. It stores the user program, recipes, archives, and firmware, enabling fast commissioning and maintenance without a PC connection.

Who is it for

This card is essential for control engineers, system integrators, and maintenance technicians who work with Siemens SIMATIC S7-1200 or S7-1500 PLCs. It is ideal for machine builders who need to duplicate programs across multiple controllers, for plants that require quick CPU replacement without reprogramming, and for any application where data logging or recipe management is critical.

Tips

Always power down the PLC before inserting or removing the memory card to avoid data corruption. For firmware updates, copy the update files to the card and insert it into the CPU; the update starts automatically. Keep a spare card on hand to minimize downtime during CPU replacement—simply transfer the card to the new unit and power up.
