Hi Jeremy,
maybe you wrote a very helpful bit of code but unfortunately I cannot figure out what it does and how to use it:
src/System/Dev_SDCard_Program.L5X

I would like to read data from a file on the SD Card. In case your code should do this,

• where do I input the filename?
• where is the content of the file saved?
• where did you get the magic numbers from and what do they mean? (e.g. Msg.AttrAll.Class = 16#031a, MsgAttrAll.Flags = 16#0200, MsgAttrAll.Path = '$1F$00$00$00', the values in MsgAttrAllResp, 16#031A in line 13 of Sys_SDCard)

I've also found the Sample Code CF_Read_Write_Example from Rockwell but it gave an error when importing for our controller and it's far more complicated to understand (because of Ladder Code and the size and number of routines) and blows up the code due to the many routines instead of nice AOIs.) So it would be great to be able to use your code.

If it's simpler for you to write a bit here than making a proper documentation in the Wiki I will make a PR for writing this documentation and probably add some comments to the code that would have helped me.
