Product details

What this memory card does in the S7-300 rack

The 6ES7951-0KD80-0AA0 is a 16 kbyte Flash-EPROM memory card for Siemens S7-300 PLCs, built for the expanded temperature range variant. It stores the user program and data in non-volatile Flash memory so the CPU retains the application after power loss without a battery. The short-version form factor fits the standard S7-300 slot, and the 5V Flash-EPROM technology means the CPU reads it directly without a separate programming adapter.

The 16 kbyte capacity is sized for small to medium S7-300 programs. It is not enough for a large distributed application with extensive DBs and SCL code.
