More Information

Overview Manuals Card Format Flash Storage Capacity Check CPU Fit

Features:

  • Eight megabytes of Flash EPROM provide removable non-volatile S7-400 load memory.
  • The card uses the long mechanical format and a 5 V controller interface.
  • Correct selection requires the card technology, capacity, voltage, and physical format to match together.
Siemens 6ES7952-1KP00-0AA0 stores S7-400 project data on removable Flash EPROM media.

The stored load-memory contents remain on the card without relying on normal controller operating power.

An existing card should be identified by its full order number and 8 MB long-format 5 V specification before replacement.

Mechanical and Electrical Identity

  • Long design: The card body uses the documented long S7-400 format.
  • Five-volt interface: The card is identified for the 5 V memory-card slot.
  • Removable media: The card can be removed from the CPU slot when the approved handling procedure is followed.
  • Order check: The complete article number distinguishes this capacity from visually similar cards.

Non-Volatile Load Memory

  • Retention method: Flash cells retain written data without a backup battery.
  • Project storage: The card carries the load-memory image written by the supported engineering process.
  • Write behavior: Project changes are programmed to Flash rather than edited as battery-backed RAM.
  • Power loss: Removing normal controller power does not erase programmed Flash content.

Eight-Megabyte Selection Limit

  • Nominal capacity: The card provides eight megabytes of Flash EPROM storage.
  • Project fit: The compiled load-memory requirement must remain within the available capacity.
  • Replacement match: A previous card with a different capacity is not identified as the same configuration automatically.
  • Archive check: The retained project archive should be compared with the card image before commissioning.

S7-400 Compatibility Checks

  • Controller family: The host CPU must belong to the documented SIMATIC S7-400 memory-card platform.
  • Slot voltage: The memory-card interface must support the 5 V card type.
  • Mechanical length: The controller enclosure must accept the long-format card.
  • Project release: CPU firmware and engineering software must support the saved controller project.
Description
Siemens 6ES7952-1KP00-0AA0 is a long-format 5 V Flash EPROM memory card for SIMATIC S7-400 controllers. Its 8 MB capacity provides removable non-volatile load memory for controller programs and configuration data.

Because 6ES7952-1KP00-0AA0 uses Flash EPROM rather than battery-backed RAM, stored load-memory content remains on the card when normal controller power is absent. Project changes are written through the supported S7-400 engineering workflow instead of being treated as directly editable RAM.

Selection of 6ES7952-1KP00-0AA0 requires the controller slot to accept the long 5 V card format and the project to fit within 8 MB. Capacity, voltage, physical format, and full order identity must all match before an existing S7-400 card is replaced.

Technical notes
Storage on Siemens 6ES7952-1KP00-0AA0 is 8 MB of non-volatile Flash EPROM in the long 5 V S7-400 card format. Capacity and card format must both match the controller.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What must match before replacing an S7-400 card with Siemens 6ES7952-1KP00-0AA0?
Siemens 6ES7952-1KP00-0AA0 requires the long 5 V format, Flash EPROM technology, 8 MB capacity, and a compatible S7-400 CPU.
Will the project on 6ES7952-1KP00-0AA0 disappear when controller power is removed?
No. The non-volatile Flash EPROM in 6ES7952-1KP00-0AA0 retains programmed load-memory content without normal operating power.
Why can a project be too large even when 6ES7952-1KP00-0AA0 fits the CPU slot?
Mechanical fit does not change the 8 MB capacity of 6ES7952-1KP00-0AA0, so the compiled load-memory requirement must still fit.
Can Siemens 6ES7952-1KP00-0AA0 be handled like a battery-backed RAM card during edits?
No. Siemens 6ES7952-1KP00-0AA0 uses Flash EPROM, so project updates follow the supported Flash programming workflow.
What should be checked if an S7-400 CPU does not recognize 6ES7952-1KP00-0AA0?
For 6ES7952-1KP00-0AA0, check insertion, long-card support, 5 V interface compatibility, contact condition, CPU diagnostics, and the project image.
Is the card outline enough to identify Siemens 6ES7952-1KP00-0AA0?
No. Siemens 6ES7952-1KP00-0AA0 must also match the full order number, 8 MB capacity, 5 V marking, and Flash EPROM type.
