Hi,

I've a S7-1500 and every modification (even if I change a contact)  that I do, when I go to download it says that not enough memory to load.  At this moment, I stop CPU, erase data and I could load the block/s.

On online the CPU has 95% Memory Load and 10% rest of memories.

There is any solution in order download?¿

Split from high load memory.

I think you've already found it.

If the changed block doesn't fit the free memory you won't be able to download it during RUN.

Hi,

you need a bigger SMC. Your loading memory is 95%. If you download changes, the program code exists for a little while twice. When Download is finished, new code will be copied to RAM and then the old code will be deleted...

Also check the follwoing FAQ

When downloading to the S7-1500 CPU, why is the message "There is insufficient memory on the memory card for this amount of data" displayed although there is still enough memory available?
