Installation Guidelines

Ensure the PLC power is switched off before inserting or removing the memory card to prevent data corruption or electrical damage.
Handle the card by its edges; avoid touching the gold-plated contact pins to prevent oxidation or contamination.
Insert the card firmly into the designated memory slot on the S7-400 CPU until it is fully seated.
Verify that the CPU recognizes the memory card via the hardware configuration software (STEP 7) after installation.
Store in an anti-static environment when not in use to protect the integrated circuits.

FAQ

What is the primary function of the 6ES7952-1AK00-0AA0?

This module acts as a RAM memory card for the Siemens S7-400 PLC, providing necessary volatile memory for the execution of user programs and data storage during system operation.

Is this memory card compatible with other Siemens series?

No, this specific model is engineered for the SIMATIC S7-400 system. Compatibility with other series such as S7-300 or S7-1500 is not supported.

Does this card retain data without power?

As a RAM (Random Access Memory) card, it is volatile and requires the PLC's backup battery system to maintain data integrity when the main power is disconnected.
