Hello sukhoi; So, you have a battery module plugged into your CPU? A battery cartridge can normally sustain the remamnent areas of memory for a period of 200 days while the CPU is powered off, as long as it is not discharged. Unsused, the battery module has a shelf life of 5 years. See the screenshot below, taken from the S7-200 System Manual. https://support.industry.siemens.com/cs/ca/en/view/1109582 How old s the battery module? How long has the CPU been powered off? What is the status of SM0.2? Hope this helps, Daniel Chartier |
