Siemens 6ES7954-8LP04-0AA0 SIMATIC S7-1200/S7-1500 Memory Card 2GB PLC Memory Card

The Siemens SIMATIC S7 memory card (6ES7954-8LP04-0AA0) is a 3.3 V flash card with 2 GB capacity for SIMATIC S7-1x00 CPUs, rated for a minimum of 100,000 write/delete cycles at 3 g card weight and 24 x 32 mm footprint. Data retention after the final programming action is at least 10 years under normal use.

Selection Notes

2 GB is the large-capacity option in this memory card family, so choose it over the smaller 24 MB card when the program needs to store large recipe sets, data logs, or web server content on the CPU. Its 100,000-cycle write/delete rating is lower than the 24 MB card's 500,000 cycles, so it suits data storage patterns with fewer, larger writes rather than high-frequency small writes. Data retention holds 10 years if fewer than 10,000 of the rated cycles have been used.

Applications

Bulk data or recipe storage and larger user programs on SIMATIC S7-1200 and S7-1500 CPUs that need more load memory than the base 24 MB card provides.
