In the program screen, you can enter O-9999 when backing up all programs to back up all programs to PROGRAM.ALL or ALL-PROG.TXT. However, generally this file cannot be imported directly into the system. If you need to input all previously backed up programs into the system at once, you need to modify parameter 3201#6 NPE=1.
Prvý, make sure that there are no programs with the same name as the previous backup in the system list. It is best to clear the current program list.
Then on the program screen, select "Device" --> "Operation" --> "M-CARD" --> "F Vstup". Use F to select the serial number of the program backup file, then enter O-9999 and select execute.
