Flash ROM Backup
CX-Programmer supports the Monitoring function of Flash ROM Backup for the CS1x-H, CJ1x-H, or CP1H
series of PLCs. When a backup is started for a CS1x-H, CJS1x-H, or CP1H PLC the Backup Monitor dialog is
displayed automatically in online mode, when the option
‘Display Backup Monitor Dialog automatically’ is
selected on the PLC Properties dialog. It can also be invoked manually from the View | Windows | PLC
Memory Backup Status option.
The dialog is an information only dialog (or modeless) thereby enabling other operations to be executed during
the backup process.
CX-Programmer always monitors the backup status while operating in online mode.
