Hi All, I have a quick question, in regards to the new logix processors that have SD cards, I have seen the option to save/load a plc program from the SD card. However is it possible to save certain tag values to the SD card and load back again in the case of a power fail or download? if so would you have an example of code that saves two tag values to an SD card and and loads back out again? Certain values like positioner's,timers & calibration values need to be saved but not hard coded. But in the case of a power fail or re download etc this can be lost. so if we could select tags to be saved into the SD card, and if needed be loaded back into the PLC. Any sample code, or info would be appriaciated Thanks
