Hi.

Does anyone know which memory cards that are available for S7-1500 CPU series, and for Unified panels? Is there a difference between the memory cards used for CPU's and HMI's, or can they be used for both?

Hi eirik0101,

Yes, they are different cards. You need a specific card for each equipment, you can't use the same ones.

Below, I share with you the links where you can find the necessary cards. In the case of Unified panels you can find these cards (SD Memory Cards):

"SD memory cards, 512 MB, 2 GB to 32 GB for SIMATIC HMI Panels, HMI Unified and IPC"

For your S7-1500 equipment you will need to use a specific S7 Memory Card like the one I show you in the following link:

"SIMATIC S7 Memory Card, 12 MB"

I hope this information is useful for you.

Best regards!
