6ES7953-8LJ31-0AA0 Siemens Micro Memory Card SIMATIC S7 512 KB 3.3V NAND Flash-EPROM
The Siemens 6ES7953-8LJ31-0AA0 is a Micro Memory Card, an important component of the Siemens SIMATIC S7 series. This 512KB memory card utilizes 3.3V NFLASH storage technology and is designed for SIMATIC S7-300, C7 series controllers, and ET 200 distributed I/O systems. As the load memory for the S7-300 controller, it stores user programs, project data (including symbols and comments), and equipment-related operational and configuration data.
Program Storage and Execution: As an insertable load memory for the S7-300 controller, it not only stores user programs but also allows the CPU to run programs directly from the card, providing a larger program storage space than internal memory.
Data Archiving and Recipe Management: Provides data logging (archiving) and recipe management functions, which can be used to store equipment-related operational and configuration data.
Firmware Updates: Can be used to update firmware on compatible Siemens modules, ensuring the system remains up-to-date.
Convenient data transfer: Easy two-way data exchange with devices is possible via an SD card reader and Office tools.
System diagnostics: Supports integrated system diagnostics, updating diagnostic information even when the CPU is idle.
