Use of the screen switching strobe
Create a program to read the number of the currently displayed screen and to
write the number to the “screen switch setting word” at the leading edge of the
“screen switching strobe” of the PT status notify area. This program enables
screen switching by using the touch switches on the NT600S and eliminates re-
peated setting of the same screen number. If the screen switching is not
executed on the NT600S, the screen switching strobe does not need to be
checked.
For the screen switching strobe, refer to the “notifying the displayed screen to the
PC” mentioned below.
Continuous screens and overlapping screens
Continuous or overlapping screens can be displayed by designating the parent
screen. If a child screen is designated, only the child screen is displayed.
For the continuous and overlapping screens, refer to the “Classification of
screens” (page 124).
Example of Display Screen Switching
This example operates the PC switch (bit) to switch the NT600S display screen.

(2) Screen #3 is displayed on the NT600S when bit 00003 turns ON.

played screen is read and written to the currently displayed screen word in the
PT status notify area. In this case, the NT600S will not write the same screen
twice.
