I'm using a 1769-L16ER-BB1B. I'm storing recipe data in an array of user-defined data types. For disaster recovery purposes, I need to make sure the recipe data is retained if the controller should shuffle off to automation heaven. Can I save just the array to the SD card? Ideally, I'd like to save it from the logic after every write to the array.
If the tag values are saved along with the program, then perhaps saving the whole lot after every write to the array would be the better option.
Can anyone show me how to do this from the logic or point me to a Knowledgebase article that details it? I've searched the Knowledgebase but couldn't see what I needed.
