SD HC Cards for AB Compact Logix

Can an SD HC Card be used for backup or program storage for an Allen Bradley Compact Logix PLC?


As far as I know, all the most recent CompactLogix PLCs are equipped with an SD card slot. In fact, in my tutorial, I am covering a CompactLogix.


Yes, you can use but you have to be aware of the format and size.
I know that higher than 4G can cause problems as much in PLC as in Panelview, the most recommended is 1G or 2G and the format that brings the cards (1784-SD1) is FAT16.
