SIMATICSiemens 6ES7954-8LC03-0AA0 SIMATIC Memory Card 4MB S7-1200 PLC Memory Card
SIMATIC memory card, 4MB flash-EPROM, for S7-1200 CPUs and SINAMICS drives, 500,000 write/delete cycles minimum.
Description
About the 6ES7954-8LC03-0AA0
About the 6ES7954-8LC03-0AA0
The Siemens 6ES7954-8LC03-0AA0 is a 4 MB SIMATIC memory card for S7-1200 CPUs and SINAMICS drives, using 3.3V flash-EPROM storage. It supports a minimum of 500,000 write/delete cycles and retains data for 10 years when the cycle count stays under 50,000, dropping to 1 year once cycles exceed 450,000. The card measures 24 x 32 x 2.1 mm and weighs 3 grams, sized as a drop-in spare part for S7-1200 CPU slots.
Selection Notes
This is the 4 MB capacity point in the SIMATIC memory card range, sized for S7-1200 CPU program and data storage or SINAMICS drive parameter sets that fit within 4 MB; larger recipe or data-logging storage calls for a higher-capacity card in the same family. Because retention time depends on cycle count, plan for the shorter 1-year window when the card is reprogrammed frequently in service rather than assuming the full 10-year figure.
Applications
Used as the removable program and data memory for SIMATIC S7-1200 CPUs and as a parameter/firmware card for SINAMICS drives, allowing a controller or drive to be replaced without reprogramming from scratch.
