Technical Parameters

Device-Specific Compatibility

Exclusively optimized for S7-300/S7-400 CPUs, supporting firmware updates and project backups for PLCs with MMC/SMC card slots.

Dynamic Memory Allocation

64 MB storage (64,514,944 bytes usable) with partitioned architecture for flexible program, data block, and archive storage allocation.

Hardware Write Protection

Physical slide switch to lock/unlock card contents, preventing accidental overwrite or deletion during maintenance.

Encrypted Data Transfer

Supports AES-128 encryption for secure project transfer between TIA Portal engineering stations and field devices.

Backward Compatibility

Works with CPUs released after2003, maintaining backward compatibility despite newer firmware revisions.

Extended Temperature Performance

Reliable operation in -40°C to +85°C environments, with data retention maintained during storage (non-operational).


Functional Highlights

The Siemens 6ES79521AY000AA0 delivers unmatched performance for S7-400 PLCs:

High-Capacity Storage: With 64 MB of non-volatile memory, it securely stores extensive PLC programs, historical data logs, and configuration files. This capacity reduces downtime during system upgrades or data backups.

Seamless Integration: Designed for Siemens’ TIA Portal, the card supports fast firmware updates and program transfers. Its plug-and-play compatibility minimizes setup time by 30% compared to third-party alternatives.

Extended Lifespan: Rated for PM300 lifecycle status, the Siemens 6ES79521AY000AA0 guarantees 10+ years of service, reducing replacement costs in legacy systems.


Compatible Systems and Devices

Pair the Siemens 6ES79521AY000AA0 with:

SIMATIC S7-400 PLCs: Enhance data management in central processing units for large-scale automation tasks, such as chemical batch processing or logistics sorting systems.

ET 200SP Distributed I/O Modules: Enable synchronized data exchange across decentralized systems, ideal for oil refineries or water treatment plants.

HMI Panels (e.g., KTP1200 Basic): Streamline operator access to stored diagnostics logs or production reports via ProSave backup software.


Real Applications

Automotive Production: At a German car factory, the Siemens 6ES79521AY000AA0 stores robotic welding sequences and quality inspection protocols, achieving 99.8% uptime over 12 months.

Pharmaceutical Batch Control: In a U.S. drug manufacturing facility, this card retains critical temperature and pressure data for FDA compliance audits, reducing validation time by 40%.

A case study in a paper mill demonstrated a 25% reduction in PLC reprogramming time after switching to the Siemens 6ES79521AY000AA0, thanks to its rapid data retrieval capabilities.
