There are backup functions for the NJ-series Controllers that save data to SD Memory Cards and oth-

The SD Memory Card backup functions are used to back up, restore, and compare data on SD Memory
Cards. Related functions include disabling backups to SD Memory Cards and automatic transfers from
SD Memory Cards.
