Siemens S7 -> Copy RAM to ROM ? - PLCS.net

doowahdiddy · June 30th, 2005, 04:29 AM

Hello,
I use a CPU 316-2DP. Now after additional programming the memory of the CPU gets too small.
There are only Flash Memory Cards available to raise the memory of the CPU, no RAM MC´s.
Now, I should copy the complete programm on the Flash-MC, but can I do this with the PLC option "Copy from RAM to ROM" ?
I can not load the complete programm into the CPU, because the memory is too small.
So, for example, can i copy the datablocks on the CPU, then Copy from RAM to ROM, delete the datablocks on the CPU and copy the functionblocks, then Copy from RAM to ROM etc...
Or do i have to do it offline with the PC. I excpect i need a special adapter to do this :-(

Thanks a lot
