Frequency History Screen
A frequency history screen displays the screen numbers recorded by the display
history (Screen History) function in the order of frequency of screen display. This
function records the date/time of display and the number of times the screen has
been displayed for screens for which the [History] attribute is ticked in the screen
property.
The frequency history screen, provided with NT30, NT30C, NT620S, NT620C,
and NT625C, has a blank area at the right side in the screen so that scroll and
screen switching touch switches can be created. Other area of the screen must
not be changed.
The screen number of the frequency history screen is shown below.
