Note
SIMATIC Memory Card
Ensure that there is enough available storage space on your SIMATIC Memory Card for
downloading projects.
Please remember when selecting the memory card capacity that the project data of both the
CPU and SINAMICS Integrated is stored on the memory card.
In order to be able to download and back up projects, the project size and the size of files on
the SIMATIC Memory Card may not exceed 2 GB.
Do not manipulate any contents in the OMSSTORE directory on the SIMATIC Memory Card.
You can find information on reading out the storage space capacity utilization of the CPU and
the SIMATIC Memory Card in the Structure and Use of the CPU Memory
(https://support.industry.siemens.com/cs/ww/en/view/59193101) function manual.

Backing up, restoring and deleting SINAMICS Integrated NVRAM data

Backing up the non-volatile memory
The SINAMICS Integrated has a non-volatile memory, NVRAM (Non-Volatile Random Access
Memory), for operating data. Data stored in this memory includes the data from the fault
buffer, diagnostics buffer and message buffer.
In certain circumstances, for example, a defect or device replacement, this data needs to be
backed up. After changing the hardware, you transfer the backup data back to the NVRAM.
p7775 (Control Unit parameter) is used to execute the following operations:
• p7775 = 1 backs up NVRAM data to the memory card.
• P7775 = 2 copies the NVRAM data from the memory card to the NVRAM.
• p7775 = 3 deletes the data in the NVRAM.
A POWER ON is executed automatically once the data has been successfully deleted. If the
operation was successful, p7775 = 0 is automatically set. If the operation was not successful,
p7775 displays an error value. You can find further details on error values in the SINAMICS
S120/S150 list manual (https://support.industry.siemens.com/cs/ww/en/view/109822659).
