Frequently Asked Questions
How much memory does 6ES7952-1AP00-0AA0 provide?
The card provides 8 MB of RAM load memory.
Is 6ES7952-1AP00-0AA0 a RAM or Flash card?
It is a volatile RAM memory card rather than a Flash version.
Which mechanical format is used by 6ES7952-1AP00-0AA0?
The card uses the long MC 952 form factor.
Does 6ES7952-1AP00-0AA0 retain its contents without backup power?
No; the CPU backup supply must remain effective to preserve volatile RAM data.
What current should be allowed for 6ES7952-1AP00-0AA0?
Allow for up to 100 mA from the 5 V card interface.
Can 6ES7952-1AP00-0AA0 replace a same-capacity Flash card directly?
No; RAM and Flash variants have different retention behavior and must match the CPU project requirement.
What should be checked before installing 6ES7952-1AP00-0AA0?
Confirm CPU compatibility, required capacity, card type, backup condition and a verified project copy.
Compatibility & Ordering Notes
Compatibility Checklist
- Use the card only with S7-400 CPUs whose technical data supports this capacity and format.
- Maintain a healthy backup supply whenever volatile load-memory contents must be retained.
- Keep a verified offline copy of the project before removing or exchanging the card.
