dan_lorentz Posted November 1, 2011 Report Share Posted November 1, 2011 I am working on a project where I allow the user to perform a dump of information located in the data tables to a .CSV file on the SD card. I am trying to avoid users blaming me if the SD card gets corrupted so I am coming up with a procedure that must be followed before the SD card can be removed. I need to know how the SD Safely Remove function block actually works. What is the DW and what is the MB? I assumed that the MB would go from a 0 to 1 if it was safe to remove the SD Card but I checked this while performing a dump to the SD card and the MB still changed to 1. Also, I need clarification on the following sentence from the help. "It allows a current task to be completed, but prevents new ones from starting." What tasks is that referring to? Basically what I am trying to do is perform a check to make sure that it is safe to remove the SD card. Thanks, Dan Quote Link to comment Share on other sites More sharing options...
