Hello, yesterday again there was a power failure and again the original hardware configuration was restored and the same fault was there what should i do to prevent the CPU from reverting back to its previous configuration?? is it the faulty batteries that are causing this problem or should i copy RAM to ROM after downloading the modified configuration. If you are external flash memories, you need to download the final user program to that,You can find the procedure in the following FAQ.In addition, you need to replace the old batteries by checking the indications on PS or lack of sufficient power (losing internal RAM data of CPU in case of a power failure): How can I get an overview of the S7-400 memory concept?
