Siemens 6es79548lf040aa0 Simatic S7 Memory Card 24 Mb

Product Description

The SIEMENS 6es79548lf040aa0 is a Flash-EPROM memory card in the SIMATIC S7 series, designed for use with S7-1x00 CPUs and SINAMICS drives. This compact solid-state card stores program data, configuration files, and firmware directly on the controller, eliminating the need for a battery-backed RAM module to retain data during power cycles. At 24 MB of storage capacity, it provides ample space for complex automation programs. Licensed automation technicians and industrial electricians install this card as part of PLC commissioning, firmware updates, or program transfers in manufacturing and process control environments.

This memory card is suited for industrial automation installations where SIMATIC S7-1x00 series controllers or SINAMICS drive systems are deployed. Typical applications include discrete manufacturing, process automation, and motion control panels in both new installations and upgrade projects. The card slots directly into the CPU or drive unit and is recognized automatically by the controller during startup, making it a straightforward component in PLC build-out and field service workflows.
