OPERATING ENVIRONMENT · MONITORING & CONTROL

Stable project storage for installed SIMATIC systems

◈ Operating environment

Use in the approved memory-card slot of compatible SIMATIC S7-300, C7 or ET 200 equipment.

The target device supplies the card through its 3.3 V interface; the card is not a standalone storage appliance.

Keep the contact edge clean and protected from electrostatic discharge during handling and replacement.

Confirm the CPU hardware release and required card capacity before commissioning.

◎ Monitoring & control

Non-volatile Flash-EPROM preserves programmed information without battery-backed memory.

Defined write/delete endurance supports repeatable engineering and controlled service operations.

Stored controller programs and data remain available to the compatible CPU for startup and operation.

During replacement, validate the project version and memory requirement before restoring the machine.
