Features:
- A 32 Mbyte Flash EPROM provides removable non-volatile storage for an S7-400 project.
- The long-design card uses the 5 V electrical format named in the exact ordering description.
- Project capacity, storage technology, and mechanical format are identified by the complete article number.
Flash storage retains transferred load-memory content when normal controller power is unavailable.
The removable card lets the stored project remain a separate serviceable component of the S7-400 configuration.
Correct selection depends on the controller slot format and required capacity, not on the external appearance alone.
The Siemens 6ES7952-1KT00-0AA0 32 MB Flash EPROM Memory Card may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Non-Volatile Storage Behavior
- Storage medium: Flash EPROM retains written controller data without a continuously powered volatile-memory circuit.
- Capacity boundary: The card provides 32 Mbyte, so project sizing is checked against this exact limit.
- Write process: Project content is transferred using the engineering procedure intended for Flash load memory.
- Power loss: Stored Flash content remains on the card when controller power is removed.
Long-Design S7-400 Construction
- Physical design: The long card body corresponds to the documented S7-400 memory-card format.
- Electrical identity: The ordering description specifies a 5 V card, which is checked before insertion.
- Removable medium: The memory can be removed from the controller as a separate project-storage component.
- Label check: The full ordering number distinguishes this capacity and storage type from similar-looking cards.
Load-Memory Use in the S7-400
- Project carrier: The card holds transferred controller program and load-memory data for the installed S7-400 CPU.
- Startup source: The CPU reads the stored project information during the configured startup sequence.
- Capacity planning: Blocks and related load-memory content must fit within the available 32 Mbyte.
- Media handling: Power state and controller procedures are observed before the removable card is inserted or removed.
Ordering Attributes to Confirm
- Controller family: Confirm that the installed processor uses the long-design SIMATIC S7-400 memory-card interface.
- Storage type: Choose Flash EPROM when non-volatile removable load memory is required.
- Capacity: Match the engineering project to the documented 32 Mbyte card size.
- Full model: Verify every group in 6ES7952-1KT00-0AA0 rather than selecting by color or outline.
