More Information

Overview Manuals Flash Memory Card Format Controller Role Selection Checks

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).
Siemens 6ES7952-1KT00-0AA0 32 MB Flash EPROM Memory Card Manuals,Datasheets,Link 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.
Description
Siemens 6ES7952-1KT00-0AA0 is a removable 32 Mbyte Flash EPROM memory card for SIMATIC S7-400 controllers. Its non-volatile storage preserves the written load-memory content without relying on the volatile behavior of a RAM card.

The long mechanical format of 6ES7952-1KT00-0AA0 matches the documented S7-400 memory-card slot arrangement. The 5 V designation is part of the electrical and ordering identity and must be checked together with the 32 Mbyte capacity.

When a controller project is transferred to 6ES7952-1KT00-0AA0, the Flash EPROM becomes the removable carrier for stored program and load-memory data. Rewriting follows the engineering workflow for Flash media rather than the direct edit behavior of battery-backed RAM.

Selection of 6ES7952-1KT00-0AA0 therefore depends on three linked attributes: SIMATIC S7-400 use, long card construction, and 32 Mbyte Flash capacity. Matching only the visible card shape does not confirm the required memory size or storage technology.

Technical notes
Siemens 6ES7952-1KT00-0AA0 uses long-design Flash EPROM construction and stores 32 MB of S7-400 program and load-memory data without battery-backed RAM.

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 be matched before replacing an S7-400 memory card with Siemens 6ES7952-1KT00-0AA0?
Selection of Siemens 6ES7952-1KT00-0AA0 requires the long 5 V format, Flash EPROM technology, and 32 Mbyte capacity to match.
Will a project stored on 6ES7952-1KT00-0AA0 remain available after the controller loses power?
Yes. The non-volatile Flash EPROM in 6ES7952-1KT00-0AA0 retains transferred load-memory content without normal operating power.
Why should Siemens 6ES7952-1KT00-0AA0 not be handled like a battery-backed RAM card during project updates?
Siemens 6ES7952-1KT00-0AA0 uses Flash EPROM, so rewriting follows the engineering workflow for Flash media rather than direct RAM editing.
How does the 32 Mbyte rating of 6ES7952-1KT00-0AA0 affect a replacement decision?
The selected project must fit the documented 32 Mbyte load-memory capacity of 6ES7952-1KT00-0AA0 before the card is accepted.
Is visual shape alone enough to identify Siemens 6ES7952-1KT00-0AA0 among S7-400 cards?
No. Siemens 6ES7952-1KT00-0AA0 must be confirmed by its complete order number, long design, 5 V marking, and capacity.
Which controller platform should be verified before fitting 6ES7952-1KT00-0AA0?
6ES7952-1KT00-0AA0 belongs to the SIMATIC S7-400 memory-card platform, so the installed controller family must match that interface.
