Features:
- 2 MB SIMATIC S7 Micro Memory Card (MMC)
- Primarily used with the S7-300, C7, and ET 200 series
- Designed for storing PLC programs and user data, ensuring data retention for at least 10 years without power
The 6ES7953-8LL31-0AA0 is a micro memory card specifically designed for industrial automation control systems. Its primary function is to securely store user programs, system configurations, and firmware data within programmable logic controllers (PLCs). This memory card provides a stable and reliable non-volatile storage medium for control systems, enabling engineers to retain critical control logic and parameter information during equipment power outages or maintenance.
By storing complete project data on the memory card, users can achieve rapid configuration migration between multiple devices and perform firmware upgrades or recovery operations when needed. This convenient data management method not only reduces system downtime but also improves the continuity and reliability of production line operations.
The 6ES7953-8LL31-0AA0 Siemens Micro Memory Card may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

The 6ES7953-8LL31-0AA0 uses industrial-grade flash memory technology as its core storage medium, and communicates with the controller at high speed through the PLC's internal interface. When the memory card is inserted into the controller, the controller automatically reads the program and configuration and loads them into the operating environment; when the system is updated or data is saved, the controller writes the new program and parameters to the memory card, achieving persistent storage and fast retrieval.
- Program and Data Storage: Stores the entire PLC project, including function blocks (FCs), organization blocks (OBs), and hardware configuration.
- Battery-Free Backup: Provides non-volatile storage, ensuring user programs and configurations are retained for at least 10 years even in the event of a complete power outage, eliminating the need for a backup battery.
- Memory Expansion: Can be used to expand load memory when the CPU's internal memory is insufficient to support complex automation logic.
