Product details

SIMATIC S7 Memory Card — 6ES7954-8LB01-0AA0

The Siemens 6ES7954-8LB01-0AA0 is a SIMATIC S7 memory card designed for S7-1X00 CPUs and SINAMICS drives, providing 2 Mbyte of Flash-EPROM storage at 3.3 V. Rated for a minimum of 500 000 write/delete operations and 10-year data retention after final programming, this card suits applications requiring frequent recipe changes or firmware updates without premature wear.

Integration Note

The card plugs directly into the memory card slot of S7-1X00 CPUs (e.g., 1200, 1500 series) and compatible SINAMICS drive control units. No tooling or wiring required — insertion is the fit check. Flash-EPROM type means the card retains program and data without battery backup; the 3.3 V supply is drawn from the host device's internal bus.
