Hi, By the sounds of it, It is very likely that your CPU "forget" its program, and when you power it up the program gets "loaded" automatically with an older version from the FLASH card. The other possibility is that the program gets only partly erased when you power cycle the rack. This can happen due to starting power supply or battery fault. Please give us bit more information about your configuration. As background info: How can you obtain an overview of the memory concept of SIMATIC S7-300 CPUs and C7 devices? How can I get an overview of the S7-400 memory concept? Cheers |
