Checking the Expanded I/O
- Confirming Recorded Screen Data During Operation
Screens No. 1997 and No. 1998 are for displaying recorded screen data.
Either screen will be displayed according to the data display order selected.
Screen No. 1997: In order of occurrence
Screen No. 1998: In order of frequency
S When the direct connection system is used, screens No. 1997 and No.1998 are
reserved for recorded screen data display. They are unavailable for any other
purpose.
S If the screen attribute (numeral setting attribute) for screen numbers 1997 and
1998 is "user," the touch switches used to scroll the screen do not appear when
the display history is displayed during operation. In this case, create touch
switches – such as the
advance at the right edge of the screen. The size of the switches should not
exceed 40 dots (two regular touch switch widths). When using an NT30C, select
white as the background color for the screen.
