Hi, check out chapter 4.10.4 of this manual: http://support.automation.siemens.com/WW/view/de/27774410/0/en If WinLC RTX does not find a valid power-down state (showing that the controller had not been shut down correctly), it restores the work memory to its initial state from Load memory (as downloaded from STEP 7). The power-down state can be missing or unreadable if a Windows Blue Screen event occurred and WinAC Data storage is not in NVRAM. |
