Features:
- A 4 MB Flash EPROM retains S7-400 load-memory contents without battery-backed RAM.
- The long card format fits the assigned SIMATIC S7-400 CPU memory-card interface.
- The full order number and stored project must be checked before a controller exchange.
Siemens 6ES7952-1KM00-0AA0 provides nonvolatile load memory for its assigned S7-400 CPU.
Program blocks move from 6ES7952-1KM00-0AA0 into CPU work memory during loading and startup.
Handling 6ES7952-1KM00-0AA0 requires the documented controller state and an available project backup.
The Siemens 6ES7952-1KM00-0AA0 SIMATIC S7-400 MC 952 4 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).

Program Storage Relationship
- Load memory: The Flash EPROM retains loadable program and configuration contents outside CPU work memory.
- Startup transfer: The CPU uses the stored project during loading and startup according to its configured sequence.
- Capacity check: The project must fit within the documented 4 MB card capacity.
- Backup boundary: A separate project archive is still required before card or CPU replacement.
Physical and Electrical Assignment
- Format: The long card body matches the corresponding S7-400 memory-card slot.
- Interface voltage: The controller slot supplies the documented 5 V card interface.
- Order-code match: Capacity and technology must be confirmed from the complete order number, not appearance alone.
- Insertion state: Card handling follows the CPU operating-state procedure to avoid an unintended startup condition.
Controller Startup Path
- Project storage: The memory card holds the load-memory image used by the assigned controller.
- Work-memory load: Executable blocks are made available to CPU work memory from the stored project.
- Hardware data: System and configuration information must agree with the installed S7-400 station.
- Replacement check: After exchange, verify the expected project, CPU state, and diagnostic buffer before operation.
Exchange and Data Protection
- Before removal: Stop or secure the controller according to the documented memory-card procedure.
- Project backup: Archive the online project and card contents before changing hardware.
- Contact protection: Keep the card connector clean and protect it from electrostatic discharge.
- Restart check: Confirm card recognition, load-memory size, program blocks, and the intended startup mode.
