Siemens 6ES7 954-8LE03-0AA0 | SIMATIC S7 Memory Card (12 MB)
Product Overview
The 6ES7 954-8LE03-0AA0 (alternatively designated 6ES79548LE030AA0) is an industrial-grade Flash Memory Card (SIMATIC Micro Memory Card, SMC) purpose-built for SIMATIC S7-1200/1500 CPUs and SINAMICS drives. It serves as the load memory for storing user programs, hardware configurations, data blocks (DBs), and system parameters, enabling reliable program execution and rapid system deployment in industrial automation setups. As a legacy spare part (discontinued since October 1, 2024), its successor is the 6ES7 954-8LE04-0AA0.
Key Functions
- Load Memory Storage: Safeguards user programs, hardware 组态 (HW Config), data blocks, and system settings for S7-1×00 CPUs and SINAMICS drives, ensuring non-volatile data retention even during power loss.
- Rapid System Deployment: Facilitates quick program transfer and system startup, minimizing commissioning time and supporting efficient project replication.
- Data Integrity & Reliability: Delivers industrial-grade durability to withstand harsh conditions (vibration, temperature fluctuations, electromagnetic interference) and ensure long-term data retention.
- Firmware & Configuration Updates: Supports firmware upgrades and configuration changes, enabling system flexibility and adaptability to evolving automation requirements.
