Memory Function in the S7-400 System
STEP 7 / Programming Device
The user program is prepared on a programming device using STEP 7. The program can be transferred to the Flash memory card through the supported programming procedure.
Flash-EPROM Memory Card
The 4 Mbyte Flash-EPROM card stores the user program in non-volatile memory. Stored data is retained without backup voltage, including when the card is removed from the CPU.
SIMATIC S7-400 CPU
The memory card is used as CPU load memory in the S7-400 system, providing storage for the controller user program.
Program Loading and Retention
The user program can be loaded to the Flash card with the CPU in STOP through STEP 7, or loaded offline using a programming device or programming adapter.
Application & Fault Scenarios
Typical System Application
Used in Siemens SIMATIC S7-400 automation systems as Flash load memory for storing the CPU user program. It is relevant to control cabinets and established PLC installations where non-volatile program storage is required.
Maintenance & Downtime Context
Maintenance teams may search for this card when an installed memory card is missing, damaged, unreadable or needs replacement during PLC memory maintenance. An unavailable program-storage medium can delay program restoration and extend controller or machine downtime.
Memory Card Handling Notes
Confirm the Memory Card Type
The S7-400 platform uses RAM and Flash memory cards. This catalog number identifies a Flash-EPROM card. Check the installed card type and the CPU requirements before sourcing a replacement.
Check the Required Capacity
Verify that the 4 Mbyte capacity is appropriate for the installed application and existing program storage requirements.
Load the User Program
The user program can be loaded to a Flash card through STEP 7 with the CPU in STOP, or loaded offline using a programming device or programming adapter.
Preserve the Stored Program
Flash memory retains stored data when power is removed or the card is taken out of the CPU. Keep a verified program backup and follow the applicable CPU manual during replacement work.
