For information on setting the auto–paging function, please see page 78 (GT10)
and page 100 (GT30).
If using this function, please be aware that the value of the third word in the basic
communication area / word device (the number of the currently displayed screen)
changes to that of the new screen number, but the contents of the first word (the screen
number specified by the PLC) do not change. For detailed information, see page 120.
Clicking on the button displays the value setting dialog box shown below. Specify
the number of the screen to which the display is to be changed.

If the value is entered with the

hexadecimal screen number is speci-
fied, and if the value is entered with

button functions as a Clear key.
KEY POINTS
If the screen does not change as expected
If the screen is changed from the PLC, and the GT main unit
function switch parts are also used to change the screen (Change
Screen operation mode), a case sometimes occurs in which the
screen does not change, even though an instruction to change the
screen has been issued by the PLC.
Example: Screen No. 1 is displayed in keeping with the instruction from the PLC, and
the screen is changed to Screen No. 2 using the function switch parts.
