From the [Project] menu, select [System Settings], and click [Display Unit].
Open the [Extended Settings] tab and select the [Device Monitor] check box.
Transfer Project Files to the Display Unit.
The device monitor screen uses a global window on the display unit. Therefore, other global windows do not display while the device monitor executes.
Enable [Device Monitor] to automatically specify [Global Window Operation] on the [Mode] tab as [Indirect].
