Backup processing triggered by turning on SM1351 (CPU module
auto exchange function)
Data in the CPU module is backed up at a desired timing. The operation during back up differs according to the SD9350
(operation mode setting) value.
CPU module auto exchange mode (Deleting existing data)
When the SD9350 value is 1, each time the backup is requested, all of the data under the CPU data folder in the SD memory
card is deleted, and a date folder, number folder, and the backup data are created. (Only the latest backup file is stored on the
SD memory card.)
CPU module auto exchange mode (Holding existing data)
When the SD9350 value is 2, each time the backup is requested, the year, date, and serial No. of the date folder and number
folder are updated (newly created), and the backup data is created. (Multiple backup folders are stored on the SD memory
card.)
The backup files created during the backup processing triggered by turning on SM1351 (CPU module auto exchange mode)
